The WAV3000 supports standard MPEG Transport Stream input and output in either
5 P7 L+ M {* m" x. m( F7 L
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
5 O9 S6 p1 Q; I/ E$ ]2 CWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
6 c6 Z( x; ?- }; J% \2 ^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 \' B& i2 E: M# g4 @- Wpower 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
