( ^% \" E+ `1 s, W7 w2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
3 \& J! H; G! x7 b Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
3 [: H k0 L2 aWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
& [ |( t1 d% E, a; U$ h 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
0 N8 W/ E" S. Z$ m6 ]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
