The WAV3000 supports standard MPEG Transport Stream input and output in either
4 d. H3 ^. f$ a- W G* L Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
: G( }) J- s( u2 t8 @& p2 G' J WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
& u. l" y& z1 o5 j0 \# h: Ydifferent 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
