5 A% P, b7 A: a: H 9) HCI interface to the host CPU to enable flexible application development at the host level.
$ x, J2 {% ]% p' s10) Transmission of IR control signals to the video source devices from the TV location.
5 j* J f; i* o" B9 Z2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
5 B0 L8 L) L" C2 r; X2 w" h* d% n Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
O3 P9 e8 V# h u. g5 d# K3 w WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with

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
! A9 e/ g x1 Rpower 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
