specification, but it is not supported by the 4.9 GHz (public safety) WMIC.
Throughput
The throughput is a minimum of:
• 4 Mbps half-duplex at one mile line-of-sight for a 5 MHz-wide channel
• 8 Mbps half-duplex at one mile line-of-sight range for a 10 MHz-wide channel.
• 16 Mbps half-duplex at one mile line-of-sight range for a 20 MHz-wide channel.
