The WAV3000 supports standard MPEG Transport Stream input and output in either
4 O1 Q' n! n' W7 [# T! }- B; CParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
5 C3 Y( S. J0 R, ]5 _9 |WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
0 N2 c7 {1 W3 jdifferent 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
