1. Key Features
( h% G7 z) i8 }. Y2 j6 h1 S1) Complete transceiver design of wireless communication at 5 GHz.
, Y0 e8 G0 y5 P$ P, V, d5 P2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
& {" V3 D: V- X: l6 k! Q different country spectrum requirements.
5 [3 G% L, c; e8 f 3) Dynamic frequency selection to resist interferences.
8 A/ W4 a1 s3 O' ]# ^& w4) Close-loop power control to minimize power consumption and be a friendly neighbor to
5 W T8 p/ U. K3 h other WLAN networks at 5 GHz.
" O- e& d6 `. y8 y3 [4 X# r5 l 5) Secure networking to assure privacy and content rights protection.
0 A1 i/ x h5 E' V2 G- l6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,

z' A3 m8 Q+ |8 Z" r$ V systems.
, U' [- g8 O, q2 t8 e9) HCI interface to the host CPU to enable flexible application development at the host level.
. h! E* {! W% e) s10) Transmission of IR control signals to the video source devices from the TV location.
8 g5 P' R6 A. ^' p% H" w6 g 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
& a" I& H" e; j1 y( t) C% VParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
) H( g! l* Z* U+ T& \- C) O WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
B {) |! @7 s7 E" P, ]different 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
& V% N7 d% C- ]$ B/ U9 s 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
