1. Key Features
5 j8 T& I- c5 k. _ 1) Complete transceiver design of wireless communication at 5 GHz.
+ P# y5 n& i3 b$ z# V2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
' c. X. `& s- K6 ^ different country spectrum requirements.
, a7 w: Q( i* F( \8 t6 K3) Dynamic frequency selection to resist interferences.
' }6 f7 D" a1 F8 [! F; V- c& h4) Close-loop power control to minimize power consumption and be a friendly neighbor to
7 u5 d2 Y( |5 }! H0 k7 wother WLAN networks at 5 GHz.
; `5 l7 l4 A0 p& @5) Secure networking to assure privacy and content rights protection.
/ e5 Y$ [) [) N; l/ o9 y! O 6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
& o3 G; U* E6 o# |8 u/ d H.264 and VC-1 (WM-9).
; ~+ G2 l/ D# E; h3 ?1 C9 O7) Supports point-to-point video connection with full QoS and point-to-multipoint video
) e! A. F( o$ S3 pbroadcasting.
' \6 F3 `& {- ?. [. t 8) Configurable expansion I/O connector enabling easy integration with existing host
' d4 Y. R- T( H* }systems.
4 o( }( \. } j5 u0 j9) HCI interface to the host CPU to enable flexible application development at the host level.
. b+ j/ R! S3 I: {10) Transmission of IR control signals to the video source devices from the TV location.
) L' \$ X3 x: E 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
- j+ H: G( q) x$ v7 X$ \/ hParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
9 }3 ^# f1 j/ x. p; V) s9 v" Q' t7 X- _WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
2 r% o+ n0 {- {: l0 ]1 V8 v! d+ Y 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
" W8 r; P" T9 U& apower 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
4 R# V I) P# D! T3 R0 M& AMbps.
3 _$ b q V: o 3 System Security
, E Y- n) J: u! e$ O- ~ The communication is authenticated and the media stream is encrypted to assure for
5 }0 W1 y: K6 E6 P protection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
$ ]9 K( K5 S/ x$ `7 Tensures private communications between each pair of units. This also allow for coexistence of
* j- d% \: q; H4 e8 E multiple pairs of simultaneous operations without cross talk.
