* j- I0 O- l2 X: z# e/ k 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
% R7 @5 v' }( ]' Z6 d" ^5 SParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
: g! O) u8 N- L# d0 v* [1 wWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
# X+ x8 [: L/ J4 z/ v6 ~6 S+ j2 u 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
% r, _: N8 E# O9 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

$ J- l' z( e f The communication is authenticated and the media stream is encrypted to assure for
/ @: e. T2 J/ s protection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
' }& N5 T) Z- b) _! nensures private communications between each pair of units. This also allow for coexistence of
