1. Key Features
w/ c0 Y$ h' D8 H& c( R: U4 \ 1) Complete transceiver design of wireless communication at 5 GHz.
1 o: s" x1 a x9 A( P8 m* b8 d 2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
7 ]* p$ v& E- Q: g different country spectrum requirements.
U% A0 _/ l) g. U3 u3) Dynamic frequency selection to resist interferences.
) E) ]) Q. L7 `1 g. C4) Close-loop power control to minimize power consumption and be a friendly neighbor to
3 G( i0 h- v2 g) rother WLAN networks at 5 GHz.
( z9 o. y% J. ~ 5) Secure networking to assure privacy and content rights protection.
* s" R- |* B! `/ t g& n 6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
+ _# E' M! S. u% x3 I, l3 @1 R H.264 and VC-1 (WM-9).
5 U$ b2 ^7 w$ @" t" U2 D+ } 7) Supports point-to-point video connection with full QoS and point-to-multipoint video
7 E- ^) A: e- s5 F/ s7 Y broadcasting.
1 ]1 _( x0 m6 P6 s5 J& z" I8) Configurable expansion I/O connector enabling easy integration with existing host
# k7 T' X8 w* ssystems.
) b' \, c- ~% B' e7 q4 F 9) HCI interface to the host CPU to enable flexible application development at the host level.
8 d: E8 y/ t! K; a8 S2 O+ \$ H7 C10) Transmission of IR control signals to the video source devices from the TV location.
7 v5 O" J. d; T5 o; q. A! { 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
: Y4 ~) P" U2 Q* l+ w8 f$ k Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
, F% N. Z$ y& o HWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
( J, e, L: ~1 j) P+ ]0 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
4 c1 f0 d) R- U 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
