WirelessGRID-300 Backhaul 

Ethernet Compatibility 

WirelessGRID-300 wireless bridges can be attached directly to 10BASE-

100/1000 BASE-TX (twisted-pair) Ethernet LAN segments. These 
segments must conform to the IEEE 802.3 specification. 
 
Each WirelessGRID-300 bridge functions as an Ethernet node and 
performs layer 2 bridging by moving packets from a network in one 

building to a network in another building. 
 

Radio Characteristics 

WirelessGRID-300 bridges utilizes a radio modulation technique known as 
Orthogonal Frequency Division Multiplexing (OFDM) capable of operating 
in the4.940-4.990 & 5.725-5.850 GHz bands.  Data is transmitted over a 
radio channel at signaling rates up to 300 Mbps in 5.8 GHz band and 130 
Mbps in the 4.9 GHz band.   
 

Antenna Options for 5 GHz Operation 

The outdoor version of the WirelessGRID-300 bridge uses FCC certified 
antennas to achieve a maximum operating range up to 30 miles under FCC 

rules in the 5.8 GHz band. When using antenna in the 4.9 GHz band, an 
antenna gain greater than 26 dBi, will require the user to reduce the radio 
output power by the amount of gain abover 26 dBi.   
 
This device has been designed to operate with the antennas listed 

To reduce potential radio interference to other users, the antenna type and its 

gain should be so chosen that the equivalent isotropically radiated power 

(e.i.r.p.) is not more than that permitted for successful communication.
