2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
) d) H/ m9 T: g- C
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ i- A# a4 M5 x6 ] d0 YWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
$ n$ X q, n" B: c! ^5 B# Bdifferent 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
