& t- [7 j. V9 J! y3 D3 \" o 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
h8 W Z$ I u* T) l Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
7 h9 i# I) j0 I- q& F' t WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
+ n7 x) ^) R4 Jdifferent 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 J$ Q' [( ?1 ?, O. rpower 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
