- t$ T8 z/ \& i7 b% W 2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
' \5 E( \8 A! b! q# I/ W different country spectrum requirements.
/ i; I; K# k0 l% b1 s+ Y 3) Dynamic frequency selection to resist interferences.
0 c$ K- ?! A. B- }4 J4) Close-loop power control to minimize power consumption and be a friendly neighbor to

% T& F& l2 Q2 a( a 8) Configurable expansion I/O connector enabling easy integration with existing host
# j1 w2 W. s m5 y& q Jsystems.
7 l$ [' y( l! d9) HCI interface to the host CPU to enable flexible application development at the host level.
- ]! \0 ^( F6 q7 F6 i+ z" ]/ n3 }: ] 10) Transmission of IR control signals to the video source devices from the TV location.
+ c; w$ r) u" _0 d5 m$ d- Z 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
( U5 Q1 k0 L# G) s Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
- p9 F7 g/ g: U# G+ v* B! jWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
S* T! h ?! b5 a1 v( b9 ]5 Ydifferent 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
9 q2 V6 p% l6 _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
