( j# m$ H/ G) }' u2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
2 h* M: v0 `- s/ A5 ]Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ P" x0 ?3 s+ m" B! F7 H
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
( l5 H" q; a( ^" s; V* J! Z3 V
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
4 T+ f! Y) s& I5 Ipower 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
