There are two WLAN modes. One is how a small number of devices to communicate with each other directly called Ad Hoc mode (Ad Hoc Mode). The other is how to communicate with each device via the Access Point is called infrastructure mode. The WLAN also has a standard name which is IEEE 802.11. The IEEE 802.11 standard was created in 1997, 802.11b, 802.11a, 802.11g, 802.11n as a standard order.

Each WLAN network has a value of the SSID (Service Set ID). This is the value to use the WLAN network classification and identification is accomplished to 32 ASCII characters. Typically, programs that help (for example: ZCF-Zero Configuration Utility- MS Windows) users, etc. to automatically collect the SSID of the AP for the WLAN easy to use without any special operation in the detection range for most of the operating system provides The. Separately, also most of the NIC manufacturer offers dedicated control programs for their products. The overlapping cells using two or more AP called the Extended service set.

Finally, if the engineer to install the WLAN before or after the installation does not work, do the work of a site survey (Site Survey). Determine the appropriate AP position during this operation, oozing around the signal strength measurement, dead spots (areas WLAN is not working) Checking presence, client checks such things as whether a problem with the signal received from the AP and in particular the site survey when the notebook equipped with a WLAN card and a useful way to determine traveled directly back.

The IEEE 802.11 standards are used to define wireless technologies. Most of us, if not all of us are familiar with the term Wifi. These standards are used to define the technologies that operate using non-wired transmission mediums. There are many subsets of standards for the 802.11 family.

            The 802.11b standard supports speeds of up to 11 Mbps and operates at 2.4 Ghz. 802.11a replaced the b standard and offers 54 Mbps speeds at 5 Ghz. 802.11g operates on the 2.4 Ghz band for longer broadcast distances, while offering 54 Mbps. 802.11n is backwards compatible with b/g, offers 300 Mbps, and uses MIMO to combine wireless signals for higher speeds. 802.11ac offer up to 1300 Mbps at 5 Ghz and 450 at 2.4 Ghz (Mitchell, 2015).

Bluetooth is a wireless technology that allows devices to be connected within a very short range. Bluetooth uses standard specific protocols for network communication. Bluetooth works in a range up to 10 meters and can offer 25 Mbps speeds (Mitchell, 2016). Bluetooth does use the 2.4 Ghz range, interfering with any other network or electronic device operating in that band.
