2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
* y+ ?0 J0 s: w3 q1 OParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
6 i$ [" C; O/ t0 f0 TWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
' F& q5 A& S2 ~
different 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
