2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
, W3 J( I7 _& {% y+ FParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ q( a, V6 A3 O8 d8 X1 l7 j( h ^
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
9 C' I( ?* Z. ?; r+ ?( o6 |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
' n* C+ }( y9 M6 w
power 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
