This book explains the functional parts of a Wireless LAN system and their basic operation. You will learn how WLANs can use an access point to connect to each other or how they can directly connect between two computers. Explained is the basic operation of WLAN systems and how the performance may vary based on more....

802.11B Radio System

This diagram shows the basic radio size used in the 802.11b system. This example shows that the radio channel in the 802.11b system is 25 MHz wide and that the center frequency of the radio channel can be assigned to different points (channels) in the 96 MHz industrial, scientific, and medical (ISM) unlicensed frequency band. This example shows that there can be up to 3 non-interfering (non-overlapping) 802.11b radio channels operating in the same ISM frequency band.

802.11 System Types

This figure shows the different product groups of 802.11 systems and how the data transmission rates have increased in the 802.11 WLAN over time as new more advanced modulation technologies are used. The first systems could only transmit at 1 Mbps. The current evolution of 802.11A and 802.11G allows for data transmission rates of up to 54 Mbps.
