1. Key Features
$ U; E, D, z1 G& n- `! B 1) Complete transceiver design of wireless communication at 5 GHz.
* p8 Y/ S1 Y- k1 `2) Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
4 F1 r$ m# Y" {7 L8 \ different country spectrum requirements.
" s6 w1 ^: k& o) y1 S3) Dynamic frequency selection to resist interferences.
( a, Z- x0 d% r/ j+ U) B 4) Close-loop power control to minimize power consumption and be a friendly neighbor to

" Z" \5 h2 d1 \; V- d1 S( u 8) Configurable expansion I/O connector enabling easy integration with existing host
/ i2 w6 D* H! k, O8 Y' ysystems.
: ` ^ ]2 w$ J z. \9 U) w$ i 9) HCI interface to the host CPU to enable flexible application development at the host level.
( A4 k ?, y4 m, r 10) Transmission of IR control signals to the video source devices from the TV location.
" z; b; U' g( L& t& M2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
9 t+ ~4 Z7 ^# p, F+ M' s8 [ Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ d+ f! G" h" n4 ?5 YWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
4 o f" i0 G- _5 u/ E4 K# Wdifferent 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
- u9 \5 |! E( F/ b# rpower 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
