: p S6 [- P6 f4 I/ H 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
) i1 [' Z1 f. F/ }3 t0 \) r2 ^: H7 T0 w Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
( M) F# h- ^; [2 S( EWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
+ T( U; b/ x9 c/ a# ^ 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
$ T# i6 S4 ^2 O7 T2 i! l+ _5 [' a2 b 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
