The WAV3000 supports standard MPEG Transport Stream input and output in either
4 ?9 Q8 [* x5 R- e8 e# L( HParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
3 N) p e9 F/ PWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
1 @) I) l4 ?( H6 V0 ?( G) r6 [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
7 Z; y! s- S1 P# {; ]* x7 ~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
