The WAV3000 supports standard MPEG Transport Stream input and output in either
0 B7 P. S- a: w7 G( y* H0 C" t" d RParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
# c6 U. |; C3 x/ e, H/ Q
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
5 N9 }- ~5 Y, E6 V z) W- ?, kdifferent 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
3 Q; f" W/ J6 u6 ?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

3 System Security
; u' P1 k' [/ s
The communication is authenticated and the media stream is encrypted to assure for
