The WAV3000 supports standard MPEG Transport Stream input and output in either
, [' @. F1 [& q% mParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the

WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
; Q/ r) [; \8 A; y& p; ?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
" E' z' m! _) l. Y6 Y0 Q5 P2 hpower 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
