2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
6 @1 T1 t# f, w; X6 Z3 gParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
/ j! [' w- W9 k" i8 i4 r! d! Y" [
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
8 @2 r. Y" ~' G! E0 \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
( L& Y* E6 x/ x9 |* _
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
