The WAV3000 supports standard MPEG Transport Stream input and output in either
/ B! A5 d e, Q! q) Y8 L0 m( aParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
+ A/ h7 G5 L, i+ w2 J& Y6 c WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
9 A# r/ |, w3 r+ ddifferent 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
5 c' Z9 ]/ b/ Z l& U! h; u4 } 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
