2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
) E* j& S* l2 z7 sParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
. `& c9 Z- C' I& x R0 |7 a8 Y' f4 MWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with

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
