2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
3 i N4 f0 o* |$ [8 s0 `) M8 z8 [: UParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
1 q8 l a/ e7 D7 uWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
( T! Q2 [( O- c/ ~& l
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 c! \# G2 r7 f' x; I$ _
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
