PRO 11 SERIES WIRELESS ETHERNET
Each wireless LAN cell requires some communications and traffic management.
This is coordinated by an Access Point which communicates with each wireless
station in its coverage area. Stations also communicate with each other via the
Access Point, so communicating stations can be hidden from one another. In this
way, the Access Point functions as a relay, extending the range of the system.
The Access Point also functions as a bridge between the wireless stations and the
wired network and the other wireless cells. Connecting the Access Point to the
backbone or other wireless cells can be done by wire or by a separate wireless link,
using wireless bridges. The range of the system can be extended by cascading
several wireless links, one after the other.
