3Com 3CRWEASYA73, WL-575 manual Data Rates

DATA RATES

Using the 5.0 GHz integrated antenna, two WL-575 bridges can operate over a range of up to 15.4 km (9.6 miles) or provide a high-speed connection of

54 Mbps (108 Mbps in turbo mode). However, the maximum data rate for a link decreases as the operating range increases. A 15.4 km link can only operate up to 6 Mbps, whereas a 108 Mbps connection is limited to a range of 1.3 km.

When you are planning each wireless bridge link, take into account the maximum distance and data rates for the various antenna options. A summary for 5.0 GHz (802.11a) antennas is provided in the following table.
