2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
- ?' z/ J* f$ ~ q: tParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
7 t: C2 y4 x: M% A
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
7 A. x8 I* e" Y/ o3 @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
8 |0 ~& Y: Q6 n7 ^2 `: W/ _
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
