Integrated High-Gain Antenna
The MRW55 wireless bridge includes an integrated high-gain (17 dBi) flat-panel
antenna for 5 GHz operation. The antenna can provide a direct line-of-sight link up
to 15.4 km (9.6 miles) with a 36 Mbps data rate.
External Antenna Options
The MRW55M Master bridge unit does not include an integrated antenna, but
provides various external antenna options for both 5 GHz and 2.4 GHz operation. In
a point-to-multipoint configuration, an external high-gain omnidirectional, sector, or
high-gain panel antenna can be attached to communicate with bridges spread over
a wide area. The MRW55 and MRW55M units both require the 2.4 GHz 8 dBi
omnidirectional external antenna for 2.4 GHz operation. The following table
summarizes the external antenna options:
External antennas connect to the N-type RF connectors on the wireless bridge using
the provided coaxial cables.
