2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
8 L4 D# V7 U6 E# \4 a, m
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
: q4 `4 Z# |' ]8 |& q5 a. O
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
- ^4 D, ?# W- k0 [% ]2 l
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
