Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
* \! y- L5 ~; y6 Kdifferent country spectrum requirements.
The system support data rates from 6 Mbps to 60 Mbps.
The system supports video bit rates from 3 Mbps to 45 Mbps.
Proprietary radio resource control with dynamic frequency selection (DFS) and close-loop
7 @. s2 E( c( n8 v. Vpower control (CLPC).
Overall video propagation delay of less than 30 ms.
Receive sensitivity is –86 dBm for video rate of 6 Mbps, and –78 dBm for video rate of 20
