Wireless networks have widely been accommodated in many telecommunication industries and businesses due to their cost-saving nature as the organization do not need to install cables in order to transmit information.  A good example of a wireless network is WLAN commonly known as wireless local area network. It uses waves to link computer devices or internet devices within a limited range but through the gateway, WLAN can provide a larger coverage. To enhance the security the system is equipped with WEP and WPA that enables the users to customize the security of their connections against unauthorized access. (Lu et al., 2014) Since the time of its inception into commercial use, WLAN has exhibited the following prevalent merits to its users.

The network provides connections to areas where it would be hard to lay cables. The WLAN connections are created by the hosts that are dependent on the waves hence no need to lay cable to provide the connection between the host and the ISPs. This makes its installation very fast and less costly as no cables are needed to be laid through the walls or through a ceiling. Cabbing costs are also eliminated through the use of WLAN amongst the business and the homes use. It is, therefore, an ideal data network for both small scale and large scale users

Another advantage of the WLAN is its area of coverage, WLAN can cover up to a diameter of 100 meters when there is a need to extend the coverage it is made possible through roaming. The use of RF radio waves makes it possible for the connections to penetrate through various walls and surfaces. Where the coverage areas overlap, the users can freely move from one access point to another without even noticing the change. Due to its tailor-made features WLAN gives the users the choices of complexity to simplicity, hence making it user-friendly, ease of use and installation are also advantages of this network. (Patel & Wang, 2010).

WLAN also have some problems associated with its use. In a local area connection, when the number of users increases, the speed of the data transmission goes down. Each user is therefore subjected to a decline in the speed of the internet.  This has been the main challenge of the WLAN, the network is, therefore, unable to guarantee a user a static speed instead the speed is wholly dependent on the number of users. It is not, therefore, suitable for many users as they may end up surfing at undesirable speeds.

For people who are not experienced setting up a WLAN is really hard expertise power is needed amongst such people. Security of the network has also remained to be a prevalent problem.  Bandwidths can also be stolen by the people near the network especially if the network is not protected or the passwords can be easily predicted.

Advantages of the wireless access point

Adaptable systems administration

It is realized that aside from home systems administration, wireless systems administration in business areas frequently includes the utilization of numerous wireless gadgets, and diverse systems administration examples ought to be received in view of the earth and prerequisites. The systems administration method of the wireless switch is moderately single with low adaptability. Despite what might be expected, an AP has an assortment of modes for you to pick, which intended to be exceptionally adaptable, for example, Simplex AP, Wireless Client, Wireless Bridge, Multi-point Bridge, and so forth and it can be overseen centralized with the participation of wireless AP controller.

Multi-AP interconnection

The undertaking can plan the wireless program adaptable as indicated by its real circumstance. Multi-AP interconnection can give full play to its advantages. Multi-AP applications are commonly found in organizations however once in a while uncovered at home. In the business, the scope of single AP is constrained, so with a specific end goal to expand the scope of wireless systems and enable customers to wander consistently in the system, multi-AP interconnection will be a most loved for an undertaking.

Disadvantages:

Powerlessness to be utilized alone

Presently, numerous individuals would right off the bat consider wireless switches rather than wireless AP at the sway of building wireless systems, unless it's an expansive lodging or open spots. The fundamental reason is that a wireless AP can't be utilized alone, can't be straightforwardly associated with ADSL (Asymmetrical Digital Subscriber Loop) modem and it should be utilized as a part of conjunction with other hardware like switches, controllers, Ethernet center points, and so forth. In this way, numerous individuals would think that it’s exceptionally troublesome and less advantageous as a wireless switch.

Poor steadiness

Poor robustness is going for interface frameworks. It's not hard to realize that the link arrange is quicker and more steady than the wireless system. Wireless AP just capacities well when neglecting to manufacture a link organize.
