2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
4 E- S6 |" p$ u( ^& b1 l d- _" CParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the

Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
- T% y" [4 |$ n2 Udifferent 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
