2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
! p& f7 a+ \+ r) k. RParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
) d6 c; x5 ]! e4 e+ A6 s5 a
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
' Y) [( n$ g1 K0 V" O. `* ndifferent 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
4 _$ w$ h: C4 Fpower 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
