1. Key Features
; j& c ?* ?0 z( `/ ^1) Complete transceiver design of wireless communication at 5 GHz.
( H9 ?+ X- V6 l, R) ]* ~2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
1 C- Q$ [* L8 q3 e% ^different country spectrum requirements.
* _: S I, l) W! I7 Z. D 3) Dynamic frequency selection to resist interferences.
9 @( l1 A% S& s9 t4) Close-loop power control to minimize power consumption and be a friendly neighbor to
H( P0 @% [: l- f" H other WLAN networks at 5 GHz.
5 u0 s E' N; X 5) Secure networking to assure privacy and content rights protection.
1 u9 d- Q6 E9 {+ a/ ^1 w* l1 ?. S 6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
( Q U; _$ V% ^8 { H.264 and VC-1 (WM-9).
: J3 |6 u( ? z+ e/ [0 n2 E% s 7) Supports point-to-point video connection with full QoS and point-to-multipoint video

# x/ j- H6 T; _& r! w( F; W: C 8) Configurable expansion I/O connector enabling easy integration with existing host
$ I* |# D5 `* N" q$ n$ zsystems.
. M' t7 C5 s8 J2 S; L2 ?) h 9) HCI interface to the host CPU to enable flexible application development at the host level.
) s' H) x: C: D* P/ K3 h( W 10) Transmission of IR control signals to the video source devices from the TV location.
& X8 [! A u, d* }) t 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
' L+ v) E v+ ]! `5 w- U Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
5 K; g& ^ V( [( a1 a WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
: c( X9 J; F/ @ 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
, Y7 ^5 l3 y: B9 ^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
