* a& J$ Z$ \! K2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
( U) K6 ^! o+ g4 s. o
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
7 Z; ^# }9 x2 H% G1 ^: V
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
2 g4 i, w }1 D
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
$ c$ ]9 u, c0 H# Spower 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
