4.9-GHz Band
This band is available only in the USA. The radio operates on 16 channels, either 5-MHz wide or
10-MHz wide between 4940-MHz and 4990-MHz for the public safety community. To reduce the
interference between two consecutive intersections, use two different channels in line-of-sight, cascaded
deployments.
The throughput is a minimum of 4 Mbps half-duplex at a range of one mile line-of-sight for a
5
-MHz-wide channel, and 8 Mbps half-duplex at on mile line-of-sight range for a 10-MHz-wide
channel.
