The WAV3000 supports standard MPEG Transport Stream input and output in either
( v2 Y/ r# {. l; u+ V1 l U! zParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
4 @, y' g# B/ i- E4 S& fWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
5 ?) s! I: Y9 P: e% v- G; ~1 D9 D) Ydifferent 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
% O+ Q, W" r, G% t4 s7 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
