% J" V; r9 g, m- R5 p& \ 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
' P( X/ Q5 }2 R" c- l Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
s" W# T8 N5 b# e- ZWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
5 l( |# W* R- t2 c( a/ Mdifferent 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
: s3 M( T% D$ m+ q9 {" m 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
