$ c+ f" J. l9 J+ { g7 {0 R2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
$ K+ i* ^5 x4 n F& U8 r Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
1 n% ]. k6 U7 G+ E( X+ Z WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
* O' `4 u2 k6 p R& Z% c+ H9 Xdifferent 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
- I; o: C' N- T& b( m: H; w& ^9 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
