7 s/ F7 q6 A$ K9 y2 m 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
( G* k0 E9 q2 n" a Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
" r; B' W: f' z2 k# {, r7 s' o3 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
3 L+ p' k5 R. Z) Udifferent 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
* Y; U- ~& M6 j! c 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
