The WAV3000 supports standard MPEG Transport Stream input and output in either
/ G J+ e: j. J8 P$ L4 oParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
9 Y0 V& m6 U0 C* Z: e2 V& mWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
) |$ L# l W$ o* v/ d' v7 S, R( P 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
; h% {) g7 U% @3 `1 p power 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
