1. Key Features
5 U, G$ r5 T6 X' D& n6 ] 1) Complete transceiver design of wireless communication at 5 GHz.
. Y& B6 R$ H3 t+ e8 Z4 p8 d 2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
3 C1 Z; V0 w* W: U& y3 U( J* Xdifferent country spectrum requirements.
! @) V8 `" O n0 ^3) Dynamic frequency selection to resist interferences.
, v9 O! _+ _" X1 J 4) Close-loop power control to minimize power consumption and be a friendly neighbor to
7 R/ K4 e+ A6 Q7 Xother WLAN networks at 5 GHz.
' [" h4 m" {1 g* m5) Secure networking to assure privacy and content rights protection.
$ Y( i) F" q7 v0 s: y 6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
3 R' F5 r( R" `% c, k+ h, [ H.264 and VC-1 (WM-9).
# q: \. L0 \; j! l* d( L! Y! h7) Supports point-to-point video connection with full QoS and point-to-multipoint video

U$ d9 b: `8 q. E' q" `* Q2 z 8) Configurable expansion I/O connector enabling easy integration with existing host
# d9 f) F" j: I7 [+ q' _systems.
+ q2 G6 j9 p/ N2 S; r9) HCI interface to the host CPU to enable flexible application development at the host level.
) f U. [" B: N! r8 D( r) r9 `10) Transmission of IR control signals to the video source devices from the TV location.
+ P# F0 L( B$ ?# }: @$ T7 Q! _2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
4 L* v5 ^" b& g0 u1 RParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
; E8 P a2 X4 b0 p6 MWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
8 s# h/ f; c3 Odifferent 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
0 O7 S& X' m/ e 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
" [7 }" X. N9 @Mbps.
4 r, F9 _, ]/ y6 B: U/ I3 X$ M# P 3 System Security
- t) ?1 _9 o* F The communication is authenticated and the media stream is encrypted to assure for
