) w3 ]+ s8 f$ D& ^) a 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
( K5 I! s! R7 U1 oParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
7 s$ T: A1 `/ l WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
) K8 c3 Y* }% [0 adifferent 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 A Z/ r/ ]6 r8 _ 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
