Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
" k' V. }: r7 Edifferent 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
