2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
2 g: z$ [! ?3 \7 J6 DParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
. p/ ^1 b3 m( \1 |WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
0 @' V" y1 L9 g* d( K+ L: Z# zdifferent 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
8 G* L! D* e- ~1 ?1 npower 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
