Note
One-MHz channel spacing for Channel Center Frequencies is documented in the TIA TR-8
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 range 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.
Modulation
Table 6-9
lists the modulation supported modulations and data rates.
