2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
5 B, V F+ `& L' Y7 s5 W$ XParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
" ~. l5 l( w, Q" iWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
3 f" ^" v( Z. T' \
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
2 u f1 c4 N& Q4 g
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

3 System Security
: S1 H. P, m; [% P% Z& G! o: R W
The communication is authenticated and the media stream is encrypted to assure for
" {# E0 W$ N$ W/ O; Eprotection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
