2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
( a9 d; k7 B- p3 X; u, H
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
0 r. E: {* ?/ l: J. ]WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
+ c9 N0 e1 u- [& d7 G7 |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 G$ s' q5 ^, h- D5 h$ S# A' S/ Z
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
