" ~5 Z* g0 {& F7 o4 N* ]' i. y2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
$ d7 E7 }" V$ l2 k3 \1 q5 W' K Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
' m! B; X3 G# v5 s( U WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
+ l2 F" r/ I) D; n# S& [. X9 `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
% {" L9 [& d( L. npower 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
