1. Key Features
+ H% u3 G7 T- }$ ]' C% u/ M6 t 1) Complete transceiver design of wireless communication at 5 GHz.
( L& X' c2 G6 s. Z' h- ]2 c2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
# l/ u5 t/ Z. u1 ?0 w4 \ different country spectrum requirements.
7 z- t) U( [! ?& L 3) Dynamic frequency selection to resist interferences.
4 [/ j* V, Q1 e 4) Close-loop power control to minimize power consumption and be a friendly neighbor to
( j) b+ M! u2 C9 Y3 ]other WLAN networks at 5 GHz.
1 ^5 S# H. }9 E5 e8 t1 D0 {! Q 5) Secure networking to assure privacy and content rights protection.
+ \9 r! r) k1 w i+ c( l, F 6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
7 [ K; F! B' g. [9 f$ E( d H.264 and VC-1 (WM-9).
7 g9 O" p( @; z/ k- l6 u, ] 7) Supports point-to-point video connection with full QoS and point-to-multipoint video
* s) Q; Q- l3 o6 q! I' `broadcasting.
' u; E. G9 k0 T1 n% M# {- h; T8) Configurable expansion I/O connector enabling easy integration with existing host
$ C% L2 n' K! v6 y; p; C systems.
% F" b& r3 \, ~6 @2 s 9) HCI interface to the host CPU to enable flexible application development at the host level.
4 }# B. i8 g$ W1 z( v5 @ 10) Transmission of IR control signals to the video source devices from the TV location.
/ F7 f8 I6 A8 y; r! U+ v2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
- u* u# ~5 h0 D) B) v: ] Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
# ~, J$ W+ j; a; l+ I+ V u+ |WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
, v6 Y' a% Y2 ?( A2 ]" `; h9 ldifferent 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
. J+ ]7 O5 a6 g5 i/ 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

5 e& K/ H! L; ^( k f2 } 3 System Security
, `9 Q L& j" w2 B' R* m# `& f) jThe communication is authenticated and the media stream is encrypted to assure for
# ?& E4 a5 N5 A: I. [3 I6 [) n protection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
8 f$ ~/ p; \. n9 Z4 F$ y5 M0 e' xensures private communications between each pair of units. This also allow for coexistence of
