G2 Microsystems Intros Wi-Fi Networking Module

October 20, 2008

The small, low-power module is complemented by new software applications and allows you to rapidly create Wi-Fi-based sensing and telemetry systems.

CAMPBELL, CA -- It is now possible to Internet-enable anything—even battery-powered or microcontroller-based devices—in an instant with a complete, fully-calibrated Wi-Fi networking module from G2 Microsystems.

The new G2M5477 module provides the comprehensive networking communications hardware and software that designers require—speeding product time to market, eliminating redesign and testing hassles, and making it simple to deploy basic wireless systems in as little as one day.

The new module is built on G2's powerful Wi-Fi/wireless sensing/RTLS system-on-a-chip, the G2C547, also announced today. Aided by the new chip, the module uses less power and takes up less space than any other solution on the market—and it is the only module that can enable alkaline battery-powered devices.

"Wi-Fi's growth in consumer devices is about to accelerate," said Michael Stanford, analyst at large for The Linley Group. "New low-power Wi-Fi solutions with TCP/IP offload and flexible onboard processing, like the latest products from G2 Microsystems, now make it easy to Internetenable simple, battery-powered devices."

G2 also has introduced two new software applications, Icon and Recon, that help customers dramatically reduce how much time they must spend developing software to enable the wireless systems they need. All of the G2 solutions are shown next week in booth 1022 at the Embedded Systems Conference in Boston.

"We're making it fast and easy to put Wi-Fi in anything that manufacturers and innovators can imagine. You don't have to be an RF or wireless expert, you don't have to invest in a lot of customization, and you don't have to wait to get Wi-Fi going," said Geoff Smith, G2 co-founder and CEO. "The G2 module is a complete Wi-Fi and networking solution that will truly deliver WiFi freedom as it should be."

The G2M5477 module includes a built-in antenna, a 32-bit CPU, network stack, power management system, real-time clock, and a sensor interface. The module is pre-certified for FCC regulations, and works with a simple processor—or autonomously, with no external processor at all—all helping reduce development and testing time and costs.

Further, the G2M5477 was engineered from the ground up to use the least amount of power possible. With its one-of-a-kind "sleep" and "active" modes, the module is smart enough to know just when and only when to tap its power supply, yielding years of battery life. Its "instant-on" feature also ensures the module wakes up and authenticates to the network in <35 ms, delivering no noticeable user delay.

Both new Icon and Recon software applications work with the G2M5477 module to deliver added customer benefits:

  • Icon provides easy Internet connectivity to any 8- or 16-bit microcontroller by offering a full Wi-Fi and networking slave for mains and battery-powered devices.


  • Recon makes it simple to create a sensing and telemetry application that delivers reports—communicating temperature, motion, location, battery voltage and more—over a Wi-Ficonnected Internet. It easily can be modified to meet a customer's precise requirements.

A G2M5477 evaluation kit is immediately available for designers to quickly prototype Wi-Fi applications. The module loaded with Icon software is available today in sample quantities and will sell for $22 in quantities of 10,000. High-volume production is planned for February 2009.
