2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
9 _1 }5 A+ l$ p) E' |: i0 m- zParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
# S+ S/ G. c# D' x, ^3 {WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
. [, V h" V6 S' M2 u& j" hdifferent 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
' j1 }) Q% Y) \4 apower 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
