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.

9 Mbps	14.7 km
12 Mbps	14 km
18 Mbps	12.8 km
24 Mbps	11.1 km
36 Mbps	6.5 km
48 Mbps	2.9 km
54 Mbps	1.8 km
12 Mbps Turbo	13.4 km
18 Mbps Turbo	12.8 km
24 Mbps Turbo	12.2 km
36 Mbps Turbo	11.1 km
48 Mbps Turbo	8.2 km
72 Mbps Turbo	4.6 km
96 Mbps Turbo	2.1 km
108 Mbps Turbo	1.3 km

Distances provided in this table are an estimate for a typical deployment and may be reduced by local regulatory limits. For accurate distances, you need to calculate the power link budget for your specific environment.
