1. Key Features
" b1 n7 D6 v$ d1) Complete transceiver design of wireless communication at 5 GHz.
4 S! q; R ^4 {1 y$ \4 s9 b2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
2 L! K6 _ B; Z$ S different country spectrum requirements.
% z: v0 E# k/ {2 J6 o; ^5 u 3) Dynamic frequency selection to resist interferences.
3 a7 l/ k' Y, e8 U 4) Close-loop power control to minimize power consumption and be a friendly neighbor to

0 \0 N& [! V" v9 J7 {0 s0 V( ~5 X7 S5) Secure networking to assure privacy and content rights protection.
7 [ L- p1 ?# u7 R; A 6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
$ V" t" l) I2 JH.264 and VC-1 (WM-9).
8 u$ [ c& M- H/ _; r! [ 7) Supports point-to-point video connection with full QoS and point-to-multipoint video
3 x4 n7 k1 G+ l1 A% F! N# X broadcasting.
, R; }- M0 p7 L/ }* J5 N 8) Configurable expansion I/O connector enabling easy integration with existing host
/ l8 h) H1 l: N' }6 }; Dsystems.
8 {' H/ F1 F' p9 u- a1 J 9) HCI interface to the host CPU to enable flexible application development at the host level.
# t- g6 H" l7 x- Q9 T4 \) a4 i 10) Transmission of IR control signals to the video source devices from the TV location.
& v2 _6 P3 d7 z. \5 ? 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
: s/ ]% n1 J9 i+ t1 cParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
& m+ u8 z9 `6 d6 U1 h& OWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
/ T( f6 {( C. f" m. Z# c! |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
2 c0 N; [9 E1 |5 Y* b 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
s; e0 v" j9 ]4 i$ ~4 B& C- f Mbps.
' h2 |5 { j' x+ S# D3 System Security
i- U3 i1 |" J+ h! Z$ B/ OThe communication is authenticated and the media stream is encrypted to assure for
# J; V+ d5 L, M4 Y3 Z protection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
( w9 f; A7 G4 o- n# }6 S+ f ensures private communications between each pair of units. This also allow for coexistence of
3 L* [2 Z5 ?4 f3 Z0 y1 emultiple pairs of simultaneous operations without cross talk.
