The WAV3000 supports standard MPEG Transport Stream input and output in either
" E9 l1 g) X6 a) E5 I3 q7 YParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
2 N% t& Q6 D1 wWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
4 e8 @' g' ^, ?2 C) D& @1 X' @/ f$ N 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
