Wireless Lan Port

WLAN include an access point (AP) which is used to connect to the internet. AP sends and receives radio frequency signal to the connected devices. In 1990 WLAN installation was expensive and was only deployed where the wired connection was not possible. In the late 1990s, cost decreases to implement WLAN because of using IEEE 802.11 standard. It works with a bandwidth of 2.4 GHZ (802.11b) or 5 GHZ (802.11 a). The devices which WLAN connects are also called clients.

WLAN port gives a high data transfer rate. It uses star topology in which all nodes send/receive data through access points. It works better in homes and offices. Especially in offices no extra cables are required and arranging a meeting is also easy.  It has a data transfer rate of 1-10 Mbps. Wireless LAN uses security which includes WEP or WPZ. It also uses infrared technology if required.
