The WAV3000 supports standard MPEG Transport Stream input and output in either
: u( P; O2 ^6 E4 X6 k* H; B- ~; Q- R9 oParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
8 ^8 X1 h/ |: I( P5 ~WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
U* h; J0 ]& O8 O8 S+ m8 Idifferent 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
8 [* p0 ~& F/ O+ I- cpower 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
