: E5 c7 @, E8 Y/ R/ V1 {10) Transmission of IR control signals to the video source devices from the TV location.
6 H+ R" {4 a' }, M0 | 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
! J- n$ b2 o& s% mParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the

Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
V5 h. Z/ x' r: p& b$ `& tdifferent 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
' e7 T% v* h, E 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
