2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
( P; T3 [ B" S9 Z/ f& p- H% z5 H9 ]Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
2 J4 ^$ \; N( n4 F# N8 x
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
6 R7 D4 X# v( d0 G) Sdifferent 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
