2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
$ i# e# A/ p6 T2 I
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
7 ^# o+ g D S! q$ q- r4 T
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
; T( {. e* ]! \2 z0 P9 q. ~( ]. h/ Pdifferent 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
8 q0 e/ Y/ h6 |" a+ T0 j0 gpower control (CLPC).
Overall video propagation delay of less than 30 ms.
Receive sensitivity is –86 dBm for video rate of 6 Mbps, and –78 dBm for video rate of 20
