CLASSROOM OPENER: GREAT BUSINESS DECISIONS- 5G CHANGING THE BUSINESS WORLD
5G takes advantage of higher-frequency bands in the radio spectrum that have a lot of capacity but shorter wavelengths.
5G towers are significantly smaller (the size of a minifridge) and, therefore, can be put in a variety of locations that would never have worked in the past. In urban areas, that might mean 5G towers will be on every lamppost.
Ultimately improvement to coverage will depend on carriers expanding cell towers.
5G promises to supercharge business with:
Lower latency
Greater stability
Connect numerous devices (30 billion connected devices)
Move big data fast (Gigabyte browsing speeds)
Ask your student how each of the above benefits will impact business?

Networks and telecommunications are the transmission of signals over a distance for the purpose of communication. In modern times, this process almost always involves the sending of electromagnetic waves by electronic transmitters but in earlier years it may have involved the use of smoke signals, drums or semaphore.
Today, network and telecommunication is widespread and devices that assist the process such as the television, radio and telephone are common in many parts of the world.
There is also a vast array of networks that connect these devices, including computer networks, public telephone networks, radio networks and television networks.
Computer communication across the Internet, such as email and instant messaging, is just one of many examples of telecommunication.

Computer networks are continuously operating all over the globe supporting our 24/7/365 always on and always connected lifestyles.
You are probably using several different networks right now without even realizing it.
You might be using a school’s network to communicate with teachers, a phone network to communicate with friends, and a cable network to watch TV or listen to the radio.
Networks enable telecommunications or the exchange of information (voice, text, data, audio, video).
The telecommunication industry has morphed from a government-regulated monopoly to a deregulated market where many suppliers ferociously compete.

CLASSROOM EXERCISE: QUESTION YOUR THINKING
Start the class by asking students who understands how the Internet works?
How does email go from the University of Denver to Boston University? Or how does a web page go from client to server back to client?
Go to http://computer.howstuffworks.com/internet-infrastructure.htm for an overview of how the Internet infrastructure works.
There are some great diagrams and easy to understand explanations.
To transmit one page of text over a 128,000 bps (128 kbps) DSL line would take only four-tenths of a second.
Graphics require approximately one million bits for one page. This would require about 8 seconds over a 128 kbps DSL line.
Full-motion video transmission requires the enormous bandwidth of 12 million bps, and thus data compression techniques must be employed to be able to send video over the existing telephone network.
The bandwidth determines what types of communication — voice, data, graphics, full-motion video — can reasonably be transmitted over a particular medium.
Ask your students how 5G that will reach gigabyte browsing speeds will impact business

CLASSROOM EXERCISE: BUSINESS DRIVEN DISCUSSION: DATA BITS
Have you ever wondered how your computer stores your data?
The answer: Bits. A bit, which is short for binary digit, is the smallest unit of storage on a computer. 8 bits is equal to one byte.
A byte is big enough to store a letter, number, space, or symbol.
Each time you press a key the computer translates the keystroke into a numerical code that takes up one byte of space.
For example, the sentence “Your computer stores your data.” uses 31 bytes of storage, with 8 bits per byte.
One megabyte is equal to 1 million bytes
One gigabyte is equal to 1 billion bytes
One terabyte holds a trillion bytes
Original computer hard drives only had the capacity to store 250 megabytes of data.
The first Google server had only ten 4-megabyte hard drives.
Today, personal computers can save and analyze gigabytes of data.
This is one of the key drivers of the technologies radically changing our world and environment.
It is estimated that by 2025, every second there will be 1.7 megabytes of new data created for every person in the world. That is an unimaginable amount of data.
It has been stated that future business leaders must be data literate to survive and thrive in the hyper-competitive business arena. Do you agree or disagree with this statement?
If you are a marketing major how will understanding inventory data help your career?
If you are a management major how will analyzing employee data help your career?
If you are a future business leader how will analyzing competitor data help drive your business strategies?
Overall, how will this course help prepare you for your future career?

Before networks, transferring data between computers was time-consuming and labor intensive.
People had to physically copy data from machine to machine using a disk.
Networks offer many advantages for a business including:
Sharing resources
Providing opportunities
Reducing travel
There have been many network security problems - networks are a tempting target for mischief and fraud
An organization has to be concerned about…
Proper identification of users and authorization of network access
The control of access, and the protection of data integrity
CLASSROOM EXERCISE: QUESTION YOUR THINKING
Ask your students how they would write a group paper without any networks?
How would they research if they can’t get to Google?
How would they share the paper with other students?
Why are networks so important to businesses?
Can they imagine how businesses shared data prior to networks?

CLASSROOM OPENER – 5G SET TO CHANGE EVERYTHING
5G is a capital improvement project the size of the entire planet, replacing one wireless architecture created this century with another one that aims to lower energy consumption and maintenance costs.
It’s also a huge gamble on the future of transmission technology, doubling down on consumers’ willingness to upgrade.
The most important promise made by the proprietors of 5G wireless technology -- the telecommunications service providers, the transmission equipment makers, the antenna manufacturers, and even the server manufacturers -- is this:
Once all of 5G's components are fully deployed and operational, you will not need any kind of wire or cable to deliver communications or even entertainment service to your mobile device, to any of your fixed devices (HDTV, security system, smart appliances), or to your automobile.
If everything works, 5G would be the optimum solution to the classic "last mile" problem:
Delivering complete digital connectivity from the tip of the carrier network to the customer, without drilling another hole through the wall.
An important goal of 5G is to erase the differences between wireline and wireless networking to accommodate the exploding mobility of network users.
5G promises to provide better speeds and coverage than the current 4G.
5G operates with a 5 Ghz signal and is set to offer record speeds 100x faster than 4G our current connection.
5G also increases network expandability connecting hundreds of thousands of devices.

An organization has to be concerned about proper identification of users and authorization of network access, the control of access, and the protection of data integrity.
Almost all networks require some kind of logon, including user name and password.
Many people are casual with their passwords, making them easy to guess.
A good password has both letters and numbers along with a few punctuation marks for added security.
Most corporate security goes far beyond passwords such as using a "firewall," a computer that sits between an internal network and the Internet.
The firewall allows access to internal data from specified incoming sites but tries to detect unauthorized access attempts and prevent them from occurring.
CLASSROOM EXERCISE: CELL PHONES AND AIRPLANES
Break your students into groups and ask them to research the Internet to find the reasons why people are required to turn off their cell phones when they are on an airplane. There are two reasons why cell phones are not allowed on an airplane:
The Federal Communication Commission (FCC) bans the use of cell phones on airplanes because they could wreak havoc with cell phone systems on the ground. Signals from your cell phone, when you use it on or near the ground, reach just a few cell phone nodes near you and the node that is getting the strongest signal picks up your call. If you move, while driving your car or walking, the next node picks up the call. From the air, however, your phone's signal could reach miles, hitting many nodes at once, all with equal strength. Plus, you are moving at several hundred miles an hour. Cell phone systems were not designed to handle that.
The Federal Aviation Administration, for its part, supports the FCC ban for its own reasons. They fear cell phones may interfere with navigation and other aircraft systems.
Incident reports submitted by airline crews also demonstrate the potential for trouble. NASA's Aviation Safety Reporting System's "Passenger Electronic Devises Database Report Set" -- which could be subtitled "passengers behaving badly" -- contains several reports of incidents involving passengers whose "personal electronic devices" seemed to create disturbances in aircrafts' electronic systems.

Untethered connectivity, anytime, anywhere, has fueled a major market and technology disruption, which has permeated almost every consumer market worldwide. The domino effect of the success of wireless technology has resulted in a unique opportunity for innovation and creativity in technology, marketing, and business strategy.
CLASSROOM DISCUSSION: NET NEUTRALITY
Net neutrality—the great debate has been raging for some time now, with the battle lines clearly drawn. Net neutrality is about ensuring that everyone has equal access to the Internet. It is the founding principle that all consumers should be able to use the Internet and be free to access its resources without any form of discrimination.
On one side of the debate are the ISPs, such as Comcast, that are building the Internet infrastructure and want to charge customers relative to their use, namely, the amount of bandwidth they consume. The ISPs argue that more and more users accessing bandwidth-intense resources provided by the likes of YouTube and Netflix place huge demands on their networks. They want Internet access to move from a flat-rate pricing structure to a metered service.
On the other hand, content providers, such as Google, support the counterargument that if ISPs move toward metered schemes, this may limit the usage of many resources on the Internet such as iTunes and Netflix. A metered service may also stifle the innovative opportunities the open Internet provides.
The U.S. Court of Appeals for the District of Columbia Circuit struck down the Federal Communications Commission’s net neutrality rules, which would have required Internet service providers to treat all Web traffic equally. The ruling will allow ISPs to charge companies such as Netflix and Amazon fees for faster content delivery.
Do you agree that the government should control the Internet? Should website owners be legally forced to receive or transmit information from competitors or other websites they find objectionable? Provide examples of when net neutrality might be good for a business and when net neutrality might be bad for a business. Overall, is net neutrality good or bad for business?9

QUESTION YOUR THINKING: WHERE WOULD YOU GOPRO?
Just imagine a beautiful white-tailed eagle soaring high above the French Alps.
Well, you can soar right along with this beautiful creature, getting a true bird’s eye view from the streaming wireless video sent from a GoPro camera attached to its back.
The incredible footage went viral, and now everybody from new fathers to Olympic athletes is sharing their GoPro footage.
Wil Tidman, who runs GoPro’s 40-person production team, stated, “We want to show the cameras’ diverse uses and give the users the ability to edit and share videos online.”
Currently, the company is averaging three GoPro-hashtagged videos uploaded to YouTube per minute.
Who’s Shooting All That Action Footage
People with dramatic jobs, from soldiers to oil riggers, use GoPro in their work, and Tidman’s team scours the web for potential hits. He found footage of a firefighter rescuing a cat from a burning building, and the resulting YouTube post got 18 million views.
“A father sent us footage of him throwing his baby into the air,” says Tidman. “The child had a camera on his head, and you saw the excitement of their relationship.” GoPro aired it as a 30-second spot during last year’s Super Bowl.
GoPro equipped the Rolling Stones with 40 cameras for their 2013 tour. Tidman’s team also helps indies, some of whose clips have earned them a degree of fame, proof of a GoPro bump.
In a group, choose one of your favorite products or services and create a marketing strategy using GoPro.

BUSINESS DRIVEN ETHICS AND SECURITY: WAR DRIVING: ENGINEERING OR PRIVACY?
Wired connections can be intercepted physically only via wiretapping. Wireless connections have no such security. A wireless connection is by nature radiated in all directions, and unsecured connections are especially vulnerable to attack by hackers and cybercriminals.
Google engineers decided to use their Street View cars for war driving, which is the practice of driving streets and using equipment to locate LANs using Wi-Fi, such as wireless hotspots at coffee shops and home wireless networks. Google collected information about Wi-Fi networks (such as the MAC address, SSID, and strength of signal received from the wireless access point) and associated it with global positioning system (GPS) information. Google also added code to record all unencrypted packets—or what‘s known as payload data—within range of Google’s Street View cars. But capturing payload data raises numerous privacy questions. The data captured by Google’s Street View software could be highly sensitive.7
Google’s recent controversy over war-driving Street View vehicles brings up core ethical issues regarding the wireless Internet. Google’s defense claims that there is nothing wrong with collecting data from unsecured wireless networks because those networks by nature broadcast their activity for the world to see. Do you believe that is what you are agreeing to when you join an unsecured wireless network at a coffee shop or in a hotel? When you join an unsecured network, do you agree that your activity is public? Is this agreement implicit? If it were explicit, would you agree to it?

The latest trends in cell phones reflect a convergence of voice, video and data communications
By blending information with entertainment, cell phones are center-stage in the evolving trend of mobile infotainment
A WiMAX tower station can connect directly to the Internet using a high-bandwidth, wired connection (for example, a T3 line). It can also connect to another WiMAX tower using a line-of-sight, microwave link. This connection to a second tower (often referred to as a backhaul), along with the ability of a single tower to cover up to 3,000 square miles, is what allows WiMAX to provide coverage to remote rural areas.
BUSINESS DRIVEN GLOBALIZATION: Pokémon Go for Playgrounds
John Hanke, the CEO of Pokémon Go developer Niantic, posted a video of himself testing out the Augmented Reality Playground function in the game.
Its goal is to get kids moving and have fun.
With its technology embedded in some 4,000 playgrounds worldwide, Pokémon Go gets sedentary kids to move by creating augmented reality mobile games that encourage physical play such as an enhanced hide-and-seek.
The applications are designed for children to be active 80 percent of the time.
Can you think of another way to get kids moving using wireless technologies?
How can Pokémon Go be used to help children exercise beyond a playground?

Cellular telephones (cell phones) work by using radio waves to communicate with radio antennas (or towers) placed within adjacent geographic areas called cells
A telephone message is transmitted to the local cell by the cellular telephone and then is passed from antenna to antenna, or cell to cell
In less than twenty years, the mobile telephone has gone from being rare, expensive equipment of the business elite to a pervasive, low-cost personal item.
Several countries, including the UK, now have more mobile phones than people. There are over five hundred million active mobile phone accounts in China. Luxembourg has the highest mobile phone penetration rate in the world, at 164%. The total number of mobile phone subscribers in the world was estimated at 3.3 billion at the end of 2007, thus reaching an equivalent of over half the planet's population. At present, Africa has the largest growth rate of cellular subscribers in the world, its markets expanding nearly twice as fast as Asian markets. The availability of prepaid or 'pay-as-you-go' services, where the subscriber is not committed to a long-term contract, has helped fuel this growth in Africa as well as in other continents.
BUSINESS DRIVEN ETHICS AND SECURITY: TEDDY THE GUARDIAN
Two London-based entrepreneurs are building an Internet of huggable things for sick children to make any hospital visit more like a trip to Disneyland.
Teddy The Guardian captures heart rate, temperatures, and blood-oxygen levels when a child grabs it by the paw to give it a cuddle.
All measurements are sent wirelessly to nurses' and parents' mobile devices.
The cute, cuddly teddy bear is packed full of sensors designed to track children’s vital signs and help quickly find out potential issues.
Teddy The Guardian takes from 5 to 7 seconds to record measurements and is programmed to run five times per hour.
Future versions of Teddy The Guardian will be interactive, using machine learning to find out the child’s favorite song or bedtime story and then play the related content for a more soothing hospital visit.
Big pharmaceutical companies in the United States have already placed over $500,000 in orders and plan to donate the bears to hospitals and clinics.
This is clearly a brilliant idea, and soon we will see Teddy The Guardian in many local hospitals and clinics.
Can you identify any additional markets on which Teddy The Guardian should focus?
Can you think of any ethical issues related to huggable things?
Can you think of any security issues related to huggable things?

Personal digital assistants (PDA) are small, handheld computers capable of entirely digital communications transmission
The first generation of successful PDAs were Palm Pilots.
They primarily functioned as electronic organizers with support for address books, calendars, email, notes, etc.
The PDA only occasionally needs to connect to a companion PC for "synchronization."
For instance, a PDA can be synchronized with a PC address book, calendar, and email inbox, via a USB cable.
Newer PDA models can also connect to PCs wirelessly via Bluetooth (which we describe in the next section), or connect to the Internet via wireless.
CLASSROOM EXERCISE: SPORTS SENSORS
A sensor is a device that detects or measures a physical property such as heat, light, sound, or motion and records, indicates, or otherwise reacts to it in a particular way. With wireless apps and sensors, a number of new, high-tech tools for amateurs provide coach-quality feedback to athletes of all levels, including:
Tennis (Sony): Sony recently created a tennis-tracking device and app that will let users collect the kind of game-play data that used to be available only to professionals.
Golf (Swingbyte): The ultralight sensor clips to the club and monitors speed, acceleration, arc, and other statistics.
Hockey (Fwd Powershot): The ultralight sensor fits into the handle end of the stick and measures swing speed, angle, and acceleration.
Basketball (94Fifty Smart Sensor): Embedded in a standard ball, the sensor tracks shot speed, arc, and backspin plus dribble speed and force.
Baseball (Zepp): Stuck to the knob of the bat, the sensor tracks the speed and plane of a swing and the angle of impact.
In a group, create a product that takes advantage of sensors, including what the sensor would measure and how it would deliver the feedback to the user.

CLASSROOM EXERCISE: WI-FI FOR FISHES
Not too long ago, the Seattle Aquarium decided it needed to take a deep dive into its network infrastructure and deploy wireless across its facilities.
Now, a year and half in, the aquarium has found Wi-Fi to be a tool that not only lets it serve visitors in unique ways but enriches the exchanges possible between staff members and the community, says Pam Lamon, the aquarium’s web and social media coordinator.
For instance, there are long stretches when Umi, the aquarium’s 40-pound giant Pacific octopus, doesn’t move at all.
Now, staff members armed with tablets can roam around the exhibit showing visitors videos of Umi feeding while they field questions.
Wireless even lets the aquarium interact with people who can’t visit in person.
For instance, during a recent Google + Hangout on Air, a young boy from an East Coast school asked an aquarium diver how many fish were swimming in the tank with her.
The diver, wearing a wetsuit and a facemask with a microphone and speaker, began pointing out fish.
“One, two, three, four, five, six, seven,” she counted off, before giving up and telling him there were 500, give or take a few. “It’s a little bit hard to know for sure because they just don’t hold still while we count them,” she joked.
The Seattle Aquarium is far from alone among businesses and organizations that are tapping into wireless to expand or improve services.
As wireless has morphed from a pleasant perk to a necessity for employees and clients across industries, many businesses are finding they can no longer make do without wireless or with limited Wi-Fi services.
Today, not only is there incentive to find better solutions, but companies also have access to more sophisticated equipment to help them pinpoint network problems.
From next-generation access points to cloud-based management systems, wireless tools can provide expanded capabilities, are easy to manage, and are available in a range of prices.
In a group, choose a business in your area that could benefit from wireless technology, like the Seattle Aquarium, and create a plan detailing the additional services it could offer its customers.

If using a Wi-Fi connection, WEP encrypts the data using a key converting the data into a non-human readable form.
The purpose of WEP was to provide wireless networks with the equivalent level of security as wired networks.
Unfortunately, the underlying technology behind WEP has been demonstrated to be relatively insecure compared to newer protocols such as WPA. WLANs that use Wi-Fi have a built-in security mechanism called
Wi-Fi Protected Access (WPA), a wireless security protocol to protect Wi-Fi networks.
It is an improvement on the original Wi-Fi security standard, Wired Equivalent Privacy (WEP), and provides more sophisticated data encryption and user authentication.
Anyone who wants to use an access point must know the WPA encryption key to access the Wi-Fi connection.
War chalking is the practice of tagging pavement with codes displaying where Wi-Fi access is available.
The codes for war chalking tell other users the kind of access available, the speed of the network, and if the network is secured.
War driving is deliberately searching for Wi-Fi signals while driving by in a vehicle.
Many individuals who participate in war driving simply map where Wi-Fi networks are available.

SSL Certificate An electronic document that confirms the identity of a website or server and verifies that a public key belongs to a trustworthy individual or company.
Secure hypertext transfer protocol (SHTTP or HTTPS) A combination of HTTP and SSL to provide encryption and secure identification of an Internet server.
Networks are a tempting target for mischief and fraud. A company first has to ensure proper identification of users and authorization of network access.
Outside suppliers might be allowed to access production plans via the company’s extranet, for example, but they must not be able to see other information such as financial records.
The company should also preserve the integrity of its data; only qualified users should be allowed to change and update data, and only well-specified data.
CLASSROOM EXERCISE: SNAPPING A THEFTIE
Has your smart phone ever been stolen? If so, you are not alone; more than 3 million Americans’ phones were stolen in 2013, which is twice the number in 2012, according to a Consumer Reports survey. Of course, every good entrepreneur can spot an opportunity, and a new antitheft app is one step ahead of criminals who are targeting smart phones.
Lookout is among the latest additions to the growing antitheft industry, and the app features some smart ways of helping you get one step ahead of thieves. A smart phone’s front-facing camera is often regarded as merely a portal to endless selfie photographs. But Lookout puts the camera to good use by capturing a photo of you—or of any would-be thief—when someone inputs your phone’s password incorrectly three times. That photo, or theftie, is instantly emailed to the phone’s owner, along with the device’s approximate location. The antitheft app is free to download, but this handy photo feature is not available on iPhones due to Apple restrictions and comes with an annual charge of $30.37
Lookout’s team has been adding new features to the app’s alerts, based on the methods thieves use to steal phones undetected. The app also will send emails to its owner if anyone attempts to remove the phone’s SIM card, enables airplane mode, or turns off the device. From that point, the owner can choose to lock or wipe the phone remotely.
Do you agree that antitheft apps are smart business? Are any ethical issues involved in taking thefties? How would you feel if company security policy required you to install Lookout on your cell phone? If you could add a new feature to Lookout, how would it work and what would it do to deter smart phone theft?
y on the Internet where companies need to guard against fraud, invalid purchases, and misappropriation of credit card information.

CLASSROOM EXERCISE: DIGITAL DIVIDE
Only a small fraction of the world’s population has access to the Internet, and some people who have had access in the past have lost it due to changes in their circumstances such as unemployment or poverty.
Providing network access to those who want or need it helps to level the playing field and removes the digital divide, a worldwide gap giving advantage to those with access to technology.
Some organizations are trying to bridge the divide such as the Boston Digital Bridge Foundation, which concentrates on local schoolchildren and their parents, helping to make them knowledgeable about computers, programs, and the Internet.
Other organizations provide inexpensive laptops and Internet access in low-income areas in developing countries
Why is the digital divide an issue for global business?
How can we combat issues associated with the digital divide?
Is the digital divide good or bad for society?

Untethered connectivity, anytime, anywhere, has fueled a major market and technology disruption, which has permeated almost every consumer market worldwide.
The domino effect of the success of wireless technology has resulted in a unique opportunity for innovation and creativity in technology, marketing, and business strategy.
Today’s workforce grew up with the Internet, and its members do not differentiate between corporate and personal technology.
Employees want to use the same technology they have at home in the office.
This blending of personal and business technology is having a significant impact on corporate MIS departments, which traditionally choose all of the technology for the organization.
Examples of pervasive computing devices include Apple watch, Amazon Echo speaker, Fitbit, smart traffic lights, and self-driving cars.
Pervasive computing devices are small, Internet-enabled devices and are always on or constantly available.
The goal of pervasive computing is to make devices “smart,” by collecting, processing, and sending data in real time creating a network that can understand its surroundings and improve the human experience and quality of life.
BUSINESS DRIVEN DEBATE: AUTONOMOUS VEHICLES LAWS
Each year, the number of states considering legislation related to autonomous vehicles has gradually increased.
In 2018, 15 states enacted 18 AV related bills.
In 2017, 33 states have introduced legislation. In 2016, 20 states introduced legislation.
Sixteen states introduced legislation in 2015, up from 12 states in 2014, nine states and D.C. in 2013, and six states in 2012.
Since 2012, at least 41 states and D.C. have considered legislation related to autonomous vehicles.
Twenty-nine states—Alabama, Arkansas, California, Colorado, Connecticut, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Maine, Michigan, Mississippi, Nebraska, New York, Nevada, North Carolina, North Dakota, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Virginia, Vermont, Washington and Wisconsin —and Washington D.C. have enacted legislation related to autonomous vehicles.
Governors in Arizona, Delaware, Hawaii, Idaho, Illinois, Maine, Massachusetts, Minnesota, Ohio, Washington and Wisconsin have issued executive orders related to autonomous vehicles

MDMs helps to enforce epolicies for maintaining the desired level of MIS control across platforms and geographic locations.
Just imagine your sales force deployed all over the country or the world and attempting to ensure every network they use is safe and every device is protected.
Most MIS departments implement MDM by requiring passcodes on corporate devices to ensure data encryption and, in the event of a lost device, that all data on the device can be deleted remotely.
MDM tools can also enforce policies, track inventory, and perform real-time monitoring and reporting.
An MIS department may use MDM to enforce basic security measures, such as the use of a device passcode
Bring your own device (BYOD): Employees use their own device. Save company money. Zero control over security, reliability, and compatibility
Choose Your Own Device (CYOD): Employees choose a company approved and configured device. Costs company money to purchase and maintain device. No personal use allowed. Complete control over security, reliability, and compatibility.
Company-Issued, Personally Enabled (COPE): Employees provided with corporate devices. Costs company to purchase and maintain devices. Partial control over security, reliability, and compatibility as employees can use for personal use.
CLASSROOM EXERCISE: QUESTION YOUR THINKING
Does your university or company have any of the three MDM policies?
If so, does it protect the company?
Are there any vulnerabilities in the plan?
If you had to choose one plan to implement, which would it be and why?

Mobile information management
There are three key security considerations to keep in mind as you enter the wireless world:
Start with the right equipment
Make security an ongoing process, not a one-time event
Understand that not all threats are purposeful

There are three key security considerations to keep in mind as you enter the wireless world:
1. Start with the right equipment—The wireless equipment you use in your home is not designed to meet the demanding environmental requirements of corporate environments. For corporate applications, always choose wireless gear built for corporate applications, and be sure it includes a built-in firewall to prevent unauthorized access.
2. Make security an ongoing process, not a one-time event—You can have the best cybersecurity strategies in the world—wired or wireless—but things change. Researchers continually identify new threats, and automation equipment vulnerabilities are frequently revealed. Therefore, an important part of your security strategy must be setting up systems to monitor your network and making regular updates.
3. Understand that not all threats are purposeful—Unintentional cybersecurity incidents happen regularly. Most cybersecurity threats and incidents are accidental and occur inside corporate networks. Make sure you have the policies and processes in place to keep employees from unintentionally introducing vulnerabilities to your wireless networks.

MasterCard now provides cardholders with a mobile, location-based search and directory service, so they can request the location of the nearest ATM be sent to their mobile phone via SMS (Short Message Service, aka “text message”).
The service, which works with all major mobile operators in the United States, is provided by MasterCard to cardholders free of charge (although operator text message rates may apply).
The most popular location based service used today is Global Positioning System (GPS)
The GPS is owned and operated by the U.S. Department of Defense but is available for general use around the world.
In 1993, the Defense Department made this global positioning technology available for commercial use to anyone who has a GPS device. GPS devices have special microprocessors that analyze satellite signals.

An RFID tag is an electronic identification device that is made up of a chip and antenna.
An RFID reader (RFID interrogator) is a transmitter/receiver that reads the contents of RFID tags in the area
Passive RFID tags do not have a power source, whereas active RFID tags have their own transmitter and a power source (typically a battery).
The power source runs the microchip’s circuitry and broadcasts a signal to the reader (similar to the way a cell phone transmits signals to a base station).
Passive RFID tags draw power from the RFID reader, which sends out electromagnetic waves that induce a current in the tag’s antenna.
36
RADIO FREQUENCY IDENTIFICATION (RFID)
Semipassive RFID tag - Uses a battery to run the microchip’s circuitry, but communicate by drawing power from the RFID reader
Asset tracking - Occurs when a company places active or semi-passive RFID tags on expensive products or assets to gather data on the items’ location with little or no manual intervention
RFID accelerometer - A device that measures the acceleration (the rate of change of velocity) of an item and is used to track truck speeds or taxi cab speeds
Chipless RFID tag - Uses plastic or conductive polymers instead of silicon-based microchips, allowing them to be washed or exposed to water without damaging the chip

Semipassive RFID tags use a battery to run the microchip’s circuitry, but communicate by drawing power from the RFID reader.
Asset tracking occurs when a company places active or semi-passive RFID tags on expensive products or assets to gather data on the items’ location with little or no manual intervention. Asset tracking allows a company to focus on its supply chain, reduce theft, identify the last known user of assets, and automate maintenance routines.
Active and semi-passive tags are useful for tracking high value goods that need to be scanned over long ranges, such as railway cars on a track.
The cost of active and semi-passive RFID tags is significant hence low-cost items typically use passive RFID tags.
RFID accelerometer is a device that measures the acceleration (the rate of change of velocity) of an item and is used to track truck speeds or taxi cab speeds.
Chipless RFID tags use plastic or conductive polymers instead of silicon-based microchips, allowing them to be washed or exposed to water without damaging the chip.

Social Networking Gets Mobilized. Mobility is added to existing Internet business models, services and behaviors, driving traffic for wireless operators. Teens and twenties accustomed to constant connectivity and habit-forming websites, such as MySpace and Facebook, lead a wave of membership in mobile social networks. Location social networking including friend and event finder services are gaining popularity, even in the professional and over-50 segments. Google, Yahoo!, and Skype are more compelling for users than wireless brands, which are hard-pressed to compete. Social networking applications initially are preloaded on many mobile devices sold and later become downloadable.
Mobile TV — Now Showing for Early Adopters. In the short term, wireless users are unlikely to plunk down $5.99-9.99 per month for mobile TV service. Instead, look for per-view or per-minute pricing for “sneaking,” a consumer tendency to watch key minutes of a sports event or drama while engaged in another activity. Sneaking leads to more regular viewing, and within 3-5 years, mobile TV will become an indispensable service. Broadcast TV is the primary driver of revenues and consumer adoption, but peer-to-peer video is gaining interest, too. Operators are squaring off with content providers over control of the subscriber relationship and user experience.
Multi-Function Devices Become Cheaper and More Versatile. Intense competition and margin pressure will continue in the handset market, forcing prices of third-generation (3G) handsets below $90 and making them affordable for a wide range of users. Seeking to replicate the success of camera phones, device manufacturers will produce more multi-function units with music-playing, location, video and other capabilities. Twenty percent of all handsets sold in North America are application specific — built for a usage proposition, such as music or video consumption or business productivity.
Location-Based Services: And the Winner Is ... GPS! Yes, GPS is the location technology of choice for the wireless industry. Handset manufacturers will continue to push GPS-enabled handsets as the technology evolves from popular in-car satellite navigation systems like TomTom to a broadly accepted feature in wireless phones. With Nokia having launched its first GPS-enabled handsets in early 2007 and bandwidth available to support new multimedia services, location-based service providers are building critical mass. Since there are 10 to 20 times more mobile phones sold than any other consumer electronics device, wireless is a huge driver for GPS adoption.
Mobile Advertising Breaks Loose. Major brands are shifting from basic SMS marketing to more sophisticated multimedia advertising. RBC Capital Markets expects mobile marketing revenues to balloon from $45 million in 2005 to $1.5 billion by 2010. With the technological ability to target and measure the effectiveness of mobile advertising, brands are more strategic in their approach. Rich 3G content and video services and accuracy advancements in GPS-based location services deliver further value to brands targeting existing and potential customers in innovative ways.
Wireless Providers Move into Home Entertainment. Mobile makes headway against fixed broadband operators, who have dominated Internet and cheaper voice service provision in the home. Wi-Fi will remains the primary wireless access technology. The fixed operators may be strengthened by Wi-Fi capabilities in consumer electronics devices (set-top boxes, game consoles and MP3 players) that enable cost-effective content downloads.
Wireless Security Moves to the Forefront. There is a monumental need to put strong security measures in place. This could be the year that hackers really start paying attention to millions of wireless devices, the growth in mobile data usage and vulnerable points between mobile and fixed networks. CIOs consistently cite security as their number one concern in extending network access to wireless devices. Attacks, viruses and data security now exceed device loss or theft as concerns. Emerging services, such as VoIP and mobile payments, provide additional challenges. Vulnerabilities directly affect the bottom line, corporate image, regulatory compliance and competitive advantage.
Enterprise Mobility — It’s for Real Now. Enterprises can’t resist the convenient, reliable, attractively priced, bundled mobile solutions entering the market. Corporations switch from phones to mobile computers for transactions, data collection and messaging for a wide variety of employees. Many voice communications processes, such as order placement and delivery notifications, dispatch operations and remote asset monitoring, continue to shift to wireless data to increase information access and field transaction volume across organizations. Many corporations will completely replace their cellular handsets with a combined voice/data device or a data-only device.
