海华科技营销业务处处长王明德指出，随着中国大力布建无线城市，电信运营商积极发展WLAN技术及其增值服务，中国市场上无线通讯应用正从PC 快速扩展至手持终端。「支持WAPI的模块IC，可大幅缩减手持终端开发时程、降低开发成本，可为系统厂商快速打开WAPI手持终端的应用市场。」
海 华科技的WAPI手机无线模块IC，传输速度是现行GPRS或3G上网速度的数倍以上。WAPI标准强调的网络安全加密技术，具备可控性与管理性，可以改 善信息遭窃，非法入侵等问题，解决安全疑虑。为了符合手机轻薄小巧的设计要求，海华科技采用先进的半导体微型化设计及IC封装技术，模块尺寸仅有 9.6mm x 9.6mm，并具备高可靠度，高散热性等特点。同时，搭配完整的软件支持，可符合各种手机系统，有效为手机厂商缩短产品开发时程。海华科技营销业务处处长 王明德指出，中国市场的消费者对于使用手机上网，具有高度需求，系统厂商必须快速推出多样化的手机满足市场需求，无线模块IC将是最佳方案。
在 中国网通技术发展上，有线网络、无线局域网络(WLAN)以及3G将成为中国最广泛的基础宽带网络，而在中国移动、中国电信和新联通等电信运营企业标准 中，已经明确要求WLAN设备必须支持WAPI功能。根据中国WAPI产业联盟表示，包括Marvell、Broadcom、Atheros 都正积极研发支持WAPI之芯片，预计2009年将有更多WAPI芯片在中国上市。

with WEP/WPA/WPA2/ IEEE 802.11i
The AW-GH381 is a IEEE 802.11 b/g Wireless LAN & Bluetooth Module IC;
支持wlan和Wireless PAN plan ieee802.15.1
it’s targeted to mobile devices including Mobile Phones, Digital Still Cameras (DSCs), Portable Media Players (PMPs), Personal Digital Assistants (PDAs), and Gaming Devices which need small footprint package, low power consumption, multiple interfaces and OS support. By using AW-GH381, the customers can easily enable the Wi-Fi and BT embedded applications with the benefits of high design flexibility, short development cycle, and quick time-to-market.
Compliance with the IEEE 802.11b/g standard, the
AW-GH381 uses Direct Sequence Spread Spectrum (DSSS), Orthogonal
Frequency Division Multiplexing (OFDM), DBPSK, DQPSK, CCK and QAM
baseband modulation technologies. A high level of integration and
full implementation of the power management functions specified
in the IEEE 802.11 standard minimize the system power requirements
by using AW-GH381. In addition to the support of WPA/WPA2 and WEP
64-bit and 128-bit encryption, the AW-GH381 also supports the IEEE
802.11i security standard through the implementation of Advanced
Encryption Standard (AES)/Counter Mode CBC-MAC Protocol (CCMP),
and WEP with TKIP security mechanisms. The AW-GH381 also supports
IPSec with DES/3DES/ASE encryption and MD5/SHA-1 authentication.
For the video, voice and multimedia applications the AW-GH381 support
802.11e Quality of Service (QoS).
For Bluetooth operation, the AW-GH381 is Bluetooth 2.0+Enhanced
Data Rate (EDR) compliant. In addition, the AW-GH381 also supports
Bluetooth 2.1 features.
The AW-GH381 supports SDIO and G-SPI for WLAN to the host processor. High speed UART,PCM/Inter-IC Sound(I2S), and SDIO interface are available to connect the BT core the host processor. AW-GH381 is suitable for multiple mobile processors for different applications. With the support cellular phone co-existence, the AW-GH381 is also the best solution for mobile phones and PDA phones applications.
AW-GH381 module adopts the leading-edge highly-integrated WLAN SoC. All the other components are implemented by all means to reach the mechanical specification required. AW-GH381 uses IC module integration package technology that provides customers mounting mechanism to secure the AW-GH381 module against vibration and shock on the host system. AW-GH381 uses module IC integration package technology can provide more reliable and strong electrical and mechanical performance.The AW-GH320 is a IEEE 802.11b/g wireless module IC
