/ i* e3 i1 p. @; N* { 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
2 B$ {8 v' N; {9 m; w. k. z Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
+ h1 e1 M( W; U9 A T1 W WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
; P$ G- H( e# E i# E 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
/ X- P# }; s9 G# lpower 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
