6 S' c- d& u1 u/ z2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
- t0 P/ O# B4 @( S' ^
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
1 ^( o; `0 T4 E7 R' vWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
8 M( g7 m( {9 O0 V6 ?2 z+ f5 k2 sdifferent 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
; _- S3 a: j; z; \" jpower 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
