This module provides an introduction to wireless networks in general and wireless LANs in particular Wireless networks work similar
Wireless routers perform the same job as wired routers, only they convert network traffic to a radio signal Routers in a home network are most often connected
How Wireless Networks Work Moving data through a wireless network involves three separate elements: the radio signals, the data format, and the network
OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver
A wireless LAN is a LAN that utilizes radio-frequency communication to permit central or distributed infrastructure devices or computers to operate
Even though wireless networks directly contribute only to a portion of the overall network infrastructure, attention to all network functions is necessary to
This kind of resource sharing has become more prevalent as computer users have changed their habits from using single, stand-alone computers to working on
In order to make the most effective use of wireless networking technology, 802 11b networks operate in a special band of radio frequencies around 2 4 GHz
Wireless networking has grown from only being a tool employed by academia Commercial wireless networks operate in the 2 4 to 5 GHz radio frequency (RF)
Wireless networks now operate over four orders of magnitude in data rate It provides an interface that enables the Network layer to work with any
