The WAV3000 supports standard MPEG Transport Stream input and output in either
+ h5 ]$ A3 |2 F6 A mParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
3 N* y+ Z6 }5 k& Zdifferent 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
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
. z8 w1 g- q8 {# BMbps.
3 System Security
The communication is authenticated and the media stream is encrypted to assure for
protection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
9 L* Q Q9 f; ~' w9 I* W7 s# Sensures private communications between each pair of units. This also allow for coexistence of
