- K1 j! A% i$ {2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
8 z' h+ A3 Q- @* b/ b% R' b* e
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
" y, x4 O3 [' Y, B# ?WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
2 T' e9 F1 `: _, P
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
* ^6 t; y* M" Z5 f
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
3 c. p' r& _: Y6 E/ z
The communication is authenticated and the media stream is encrypted to assure for
6 N& E0 d6 Z3 {* Mprotection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
, } f% c7 K& h1 W" c; q
ensures private communications between each pair of units. This also allow for coexistence of
2 T9 ^, m. T; pmultiple pairs of simultaneous operations without cross talk.
