The WAV3000 supports standard MPEG Transport Stream input and output in either
4 H; Z: {% R# S" O- R6 `, h5 k- l) W Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ F- r; p' s7 z' m0 d! a# @3 v0 s! [WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
$ Q& y- k( u7 o8 U6 _" 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
; b& e2 I! j3 O 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
