1. Key Features
1 t' |) U* |. u. t+ @5 G) r% v) D. J2 ^1) Complete transceiver design of wireless communication at 5 GHz.
' K; O( w: @" u 2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
, Y! g! V5 V8 t- g2 Pdifferent country spectrum requirements.
7 M% g" U7 \& \' E0 r/ z4 Q 3) Dynamic frequency selection to resist interferences.
: [$ A6 M4 I5 v 4) Close-loop power control to minimize power consumption and be a friendly neighbor to
8 F) [ F4 e6 @+ M3 Iother WLAN networks at 5 GHz.
8 s: t# a6 V' [) p$ h8 Q4 w; p: O' ?5) Secure networking to assure privacy and content rights protection.
+ t6 g) X5 P8 ^7 u6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
5 R5 ?2 e" d4 y8 U H.264 and VC-1 (WM-9).
" b1 @/ V3 O+ m: O3 T3 U6 F 7) Supports point-to-point video connection with full QoS and point-to-multipoint video
" H6 b, Y' A6 Q/ [: p. d, ]# ^broadcasting.
3 i2 ~' X* {) P; U2 @9 s! R0 B+ r9 b 8) Configurable expansion I/O connector enabling easy integration with existing host
, N9 w& r0 m. o& n5 Z% o3 dsystems.
/ n' ^! L5 p, d0 U; s* A; u. Z3 y/ M9) HCI interface to the host CPU to enable flexible application development at the host level.
. `; ~* m4 _+ ?6 s# j 10) Transmission of IR control signals to the video source devices from the TV location.
0 t6 ^3 `2 K( v N0 E 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
: X6 C2 j- \' U2 y ?) B. i* e" h Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
7 ?9 z6 t! r9 T& i3 z% PWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
" D" {- \6 z& E+ G& k4 q$ T 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
U0 ]0 M4 ?8 b/ c! z5 k 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
3 [/ a6 B! @9 w0 M Mbps.

- Z0 Q+ `8 K2 G. C8 E The communication is authenticated and the media stream is encrypted to assure for
% _" Q# ]0 o: }' \, k+ G protection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
6 I# J' P/ A3 a6 `8 _ ensures private communications between each pair of units. This also allow for coexistence of
