$ Z1 K2 J% a" P- h5 u 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
# L3 r: D& T% r* h7 C Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
' S7 ]" o; B5 n6 S* I1 F# A: w* m* R 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 R# _! Z9 h+ s" \* 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
; F, `0 t J% V% L 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
