+ _1 u" }+ |, t+ u1 G 9) HCI interface to the host CPU to enable flexible application development at the host level.
7 j( E5 t: s- y8 H2 [- X0 p$ Y10) Transmission of IR control signals to the video source devices from the TV location.
4 m8 U9 V' Y" d& M; `/ ]2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
( o+ ?3 M! ]8 ~( E2 x I' [Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the

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
' c& E# D& v9 t) h7 S1 r0 Q power 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
