The WAV3000 supports standard MPEG Transport Stream input and output in either
7 F( I4 X1 Z- NParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
, ~0 L/ g; ?" h3 Z3 J2 P, c
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
]/ e: a3 V: m5 b; w& N& Pdifferent 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
; L/ e, h" C3 C. y
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
