Wireless Bridge Applications Wireless Bridge

IEEE Standards - Wireless IEEE a, provides 54Mbps data rate at 5GHz. IEEE b, or Wi-Fi, has a maximum data rate of 11Mbps, at 2.4GHz. IEEE g, provides 54Mbps data rate at 2.4GHz. IEEE n, a proposed standard to provide 540 Mbps data rate at 2.4 GHz or 5 GHz, using MIMO (Multiple-In, Multiple-Out) MIMO transmits two or more data streams in the same radio channel at the same time. With MIMO, the maximum data rate per channel grows linearly with the number of different data streams that are transmitted in the same channel.

Channel Assignment GHz2.441 GHz2.483 GHz Frequency

802.11b & g Extended Geographic Coverage using 3 - Channel Layout Three non-overlapping channel frequencies in a non- adjacent configuration allows maximum coverage of a geographic area without cross channel interference and ensures complete RF coverage. Channels 1, 6, and 11 most popular configuration for this type of layout. Other combinations are possible.

Typical Site Survey Process Obtain floor plan / campus site map Visually inspect the floor plan Identify user areas on the floor plan Identify potential problems areas on floor plan Identify Access-Point locations and Antenna types Document all findings

Typical Site Survey Tools Laptop or PDA with Wireless adaptor Site Survey Software for Wireless Access-Points RF Analyzer Two-Way Communication Devices Antennas – Variety of types Distance measuring devices Handheld GPS device with cordinence measurement capabilities
