2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
5 G% {* Q/ q# h0 \
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
- \4 Q$ h5 U+ Z0 R* O1 zWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
, k$ F5 L |5 U/ v& }* W8 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
$ t9 u7 X( @/ Q: H# c# ^/ cpower 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
