4.3 Summary

Wireless LAN (WLAN) is very popular nowadays
Wireless LANs enable users to communicate without the need of cable. Each WLAN network
needs a wireless Access Point (AP) to transmit and receive data from users.
The major difference between wired LAN and WLAN is WLAN transmits data by radiating
energy waves, called radio waves, instead of transmitting electrical signals over a cable.
WPAN describes an application of wireless technology that is intended to address usage scenarios
that are inherently personal in nature.
WLAN on the other is more focused on organizational connectivity not unlike wire based LAN
connections.

WLAN addresses connectivity within a defined region, WWAN addresses the need to stay
connected while traveling outside this boundary. Today, cellular technologies enable wireless
computer connectivity either via a cable to a cellular telephone or through PC Card cellular
modems.
The basic purport of establishing PAN (Personal Area Network) is provide a communication
channel to the individuals, who want to carry their own digital devices .
Wireless PAN technologies utilize both radio frequencies and infrared light, depending on the
application.
