1. Key Features
a- I7 g8 M0 }& @1) Complete transceiver design of wireless communication at 5 GHz.
9 @# |# I2 P, B J: X2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
% |7 U. a# Q8 N1 u( r. Y' Ddifferent country spectrum requirements.
% l1 p% G* S: A. C f3) Dynamic frequency selection to resist interferences.
3 y2 D7 d# [# O( Q/ [: J4) Close-loop power control to minimize power consumption and be a friendly neighbor to
v7 h3 S& Z7 C C other WLAN networks at 5 GHz.
?8 c X6 \, E, n- v 5) Secure networking to assure privacy and content rights protection.
W) `& ~2 u. v& J4 f6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
1 f* a- b. u6 N6 H( U3 h+ y$ T H.264 and VC-1 (WM-9).
6 a7 }7 I( L: `2 ?7) Supports point-to-point video connection with full QoS and point-to-multipoint video
9 x+ v5 P7 n* G+ D5 ^) _$ p6 Cbroadcasting.
# f7 U! ^- a) |) T/ e 8) Configurable expansion I/O connector enabling easy integration with existing host
X$ G8 u N/ `. n$ M W systems.
7 y; x0 h' l: H+ l; }- f 9) HCI interface to the host CPU to enable flexible application development at the host level.
4 c- x# G5 g( {2 Z( v10) Transmission of IR control signals to the video source devices from the TV location.
2 C3 f1 s. ]( q 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
/ Q- L. K N- `9 i XParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
: |2 E, r: u8 u) a4 k WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
- e) p7 {! s6 L% `! Tdifferent 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
5 ^. w9 E5 g9 Z' b$ C& o 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
& f0 w8 }% C5 t5 } Mbps.
7 f1 _# P6 T; U) x3 System Security
: z9 l9 e$ `1 G+ [+ c1 X5 A The communication is authenticated and the media stream is encrypted to assure for
: ]0 x N( r& b8 n n# T protection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
' `/ L, m9 Y% s' _; y2 O9 e, G" Fensures private communications between each pair of units. This also allow for coexistence of
% a! c6 r0 F* wmultiple pairs of simultaneous operations without cross talk.
