1. Key Features
4 n0 n2 B# x4 }$ t3 E 1) Complete transceiver design of wireless communication at 5 GHz.
( h/ r! ~5 _2 l 2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
& ?- o# W3 t5 F7 V$ s* Qdifferent country spectrum requirements.
4 e2 @- W$ O9 I3 l e- n( f3) Dynamic frequency selection to resist interferences.
: @+ j4 L3 O- ?: L4) Close-loop power control to minimize power consumption and be a friendly neighbor to

5 Y$ V' P: {4 [' u: `' J) G 8) Configurable expansion I/O connector enabling easy integration with existing host
6 {$ y: z/ T8 w) Esystems.
8 [, U9 E/ t( f; _: D0 _% i8 _. M6 _ 9) HCI interface to the host CPU to enable flexible application development at the host level.
' T8 J" R4 Q& D5 k- `! Y* e10) Transmission of IR control signals to the video source devices from the TV location.
6 ^+ z3 ` I6 Q2 Z$ ]0 |9 L- B, F2 O 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
! p& f7 a+ \+ r) k. RParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
) d6 c; x5 ]! e4 e+ A6 s5 a WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
' Y) [( n$ g1 K0 V" O. `* ndifferent 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
4 _$ w$ h: C4 Fpower 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
