6 f1 Z; H. j H5 M9 r6 B F! v% M9 Y 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
s% t5 p+ @( W Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the

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 A3 }. _! d5 f+ N8 j 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
