Wireless LAN (local area network) Benefits and Limitations

qa-featured

 

Hi there,
 
How does WLAN work?
 
Wireless Land Area Networks use Radio Frequency (RF) to transmit data from one point to another without wired connections. The frequencies may vary depending upon the specific equipment being used. 
 
Cables are no longer required to make a connection with the network! Therefore WLAN ensures a way to build Local Area Network without cables. This WLAN can then be attached to an already existing larger network like internet.
 
 
Benefits of WLAN:
 
* Can access shared resources without looking for a place to plug in.
* Easier to provide connectivity in areas where it is difficult to lay cable.
* Installation is fast and easy, and no need to pull cable through walls and ceilings.
* Can be accessed to the network anywhere within range of an access point.
* Installation expenses are lower compared to wired connections.
 
Limitations of WLAN:
 
* As the users of WLAN increases, the data transfer rate to each computer will decrease accordingly.
* Lower wireless bandwidth, applications such as video streaming will be more effective on a wired LAN.
* Security is more difficult to guarantee and requires configuration.
* Devices will only operate at a limited distance from an access point. 
* Data transfer rate may change according to the obstacles between the access point and the user.
 
Latest innovation in WLAN is MIMO antenna technology.
 
Thanks.
