2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
, O5 D$ m' @. q6 C8 P% [* 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
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
/ C0 J9 N' u0 L) \8 {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
/ E: }, _3 C; C; U# y4 SMbps.
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
3 D8 K g2 C/ q7 X2 ^( u+ L% g8 I- Uensures private communications between each pair of units. This also allow for coexistence of
multiple pairs of simultaneous operations without cross talk.
