1.6 Summary

Wireless network refers to any type of computer network that uses wireless (usually, but not
always radio waves) for network connections.
It use electromagnetic waves to communicate information from one point to another without
relying on any physical connection. Radio waves are often referred to as radio carriers because
they simply perform the function of delivering energy to a remote receiver.
A wireless network is a flexible data communications system, which uses wireless media such
as radio frequency technology to transmit and receive data over the air, minimizing the need for
wired connections
Wireless local-area networks (WLAN) have evolved as the quantity and types of mobile devices
have increased. The number of devices that support Wi-Fi continues to expand.
The Institute of Electrical and Electronic Engineers (IEEE) is a professional organization of
electrical engineers that has organized a highly successful and unique standards making activity.
Wireless networking hardware requires the use of underlying technology that deals with radio
frequencies as well as data transmission. The most widely used standard is 802.11 produced by
the Institute of Electrical and Electronic Engineers (IEEE).
