2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
& ]1 b M' m9 U* ^& _Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
1 N8 X8 V/ t7 z+ d% \9 j1 }WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
$ a, Z7 x1 _9 M: N2 g( w0 ^
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
# g: T* i! E/ Q
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
& w" r' K( }; r8 b: S/ h
The communication is authenticated and the media stream is encrypted to assure for
& r/ J2 Y. k8 p2 V" @6 a5 Hprotection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
3 [8 e G- Z- l1 xensures private communications between each pair of units. This also allow for coexistence of
