The WAV3000 supports standard MPEG Transport Stream input and output in either
. J7 P- _& B2 r
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the

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
