RF Monolithics Intros 11Mb/s Version of WSN802G Module

By SIP Trunking Report Contributor

Dallas-based RF Monolithics has released the 11Mb/s version of its Battery-Powered Wi-Fi Module -- the WSN802G, a 2.4 GHz IEEE 802.11g radio transceiver module.

With WSN802G, original equipment manufacturers (OEMs) can build low-power wireless local area networking (WLAN) and sensor monitoring solutions for the global market.
The new WSN802G Revision F features GainSpan’s GS1011 System on Chip (SoC). Company officials said that it delivers more features for leveraging existing Wi-Fi infrastructure. These features include upgraded enterprise-level security; new Ad Hoc network support; and Master/Slave SPI ports delivered in a low-power 802.11b/g RF module transceiver than can run for years on batteries.
In comparison to the previous version of WSN802G, the higher 11Mb/s data rate of the newest version provides the ability to send even more sensor or application data, according to company officials.
Moreover, the upgraded WSN802G module also offers 802.1x with RADIUS support and WPA2-Enterprise security. Plus, it complies with the security protocol created by the Wi-Fi Alliance and the IEEE 802.11i standard to secure wireless computer networks.
The 11Mb/s version of the WSN802G module offers more than just more speed, said Tim Cutler, director of M2M products at RFM, adding that medical applications, among others, will benefit from the enterprise security, while wireless sensor Network (WSN) applications can make use of the SPI port functionality to directly interface the module to sensors or low-cost microprocessors.
Cutler said that the Ad Hoc mode simplifies commissioning for residential and commercial deployments as well as providing a secure point-to-point capability.
RF Monolithics is a provider of solutions-driven, technology-enabled wireless connectivity for a broad range of wireless applications -- from individual standardized and custom components to modules for comprehensive industrial wireless sensor networks and machine-to-machine (M2M) technology.
Recently, the company expanded its M2M portfolio of wireless communications products by adding a new WirelessHART-compliant RF module -- the XDM2510H -- to the company's industrial-grade RF module products.
