2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
2 v+ C( o( Q. m. Y, a3 V+ u2 s' [
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
! P0 M- m, G# x/ E0 D7 E% uWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
# R- V+ V& L, |( N+ |1 pdifferent 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
, x6 [2 t6 L9 v8 I) k/ ?9 z6 v
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
