The WAV3000 supports standard MPEG Transport Stream input and output in either
& e6 G$ g& o/ P- b! R. PParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
- p6 M4 g/ V/ L/ i, E
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
6 D- W4 r7 a: z; Y# G
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
2 ~0 n/ H; C7 A1 {9 G8 }
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

protection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
- u( H- q! d1 N. S
ensures private communications between each pair of units. This also allow for coexistence of
