2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
) \8 K: @2 F" m5 D# b0 u
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
- ]& ?+ l7 \9 Z2 }3 s
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
5 f6 k; ?: }6 j: w/ J5 f rdifferent 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
) c7 O4 g. t- U7 r
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
