The WAV3000 supports standard MPEG Transport Stream input and output in either
3 ^, s: n( L5 i0 @% `, m& F9 J Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ Y' L+ a( a# o/ i8 cWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
, G1 T& u$ P9 G, L different 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
2 @ p$ i0 g, K7 g2 [5 lpower control (CLPC).
Overall video propagation delay of less than 30 ms.
