Aug. 01, 2012 [Wi-Fi Network Controller Module] Copyright © LG Electronics. All Rights Reserved. 6 1 System Descriptions 1.1 Applications HWM-300 is a complete low power self-contained embedded wireless solution to address the connectivity demand in M2M applications. It integrates micro-controller, Wi-Fi BB/MAC/RF IC, RF front end, clocks, and on-board antenna into a small form factor module. HWM-300 can be controlled by a host device through a serial interface; it can also serve as a stand-alone Wi-Fi station or network controller. Thus, it can be used to enable wireless connectivity to the simplest products with minimal engineering resources. The HWM-300 provides standard IEEE802.11 b/g functions. The integrated CPU supports software. It can be used for a variety of different applications, such as wireless sensor node, serial to Wi-Fi transceiver, Wi-Fi network controller, Wi-Fi gateway/bridges plus internet server. When used in a system where the HWM-300 is controlled by a host CPU, the serial host interface makes it very easy to integrate. When used in a system without a host CPU, the integrated ARM9 CRUNOS can be used to run a variety of applications. 1.2 Module Summary • 2.4GHz IEEE 802.11b/g radio technology • Dimension: 33 mm × 48 mm × 1.2 mm • On-board antenna • Transmit power: +17 dBm @ 11b /11Mbps • Max receive sensitivity: -92dBm • CPU: ARM9 CRUNOS • Diverse serial interface: UART • Operating temperature range: -30ºC to 85ºC • RoHS compliant 1.3 Block Diagram Figure 1.
