4 @1 u" z5 E; r3 j9 h 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
3 x" S% t9 g+ Y( v( i) L4 b" H5 b Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
; s/ Y: a5 T* F( x! X) V R% p3 ~- z WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
( Z- e3 E7 _2 e+ s5 F 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+ f( t( ]$ n% X 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
