Wi-Fi network controller module introduced for M2M market

Murata Wireless Solutions (MWS), a manufacturer of wireless modules, on Tuesday announced the introduction of its Wi-Fi Network Controller Module.  The SN8200 is a small, low power, self-contained, certified Wi-Fi network controller module that provides serial-to-Wi-Fi connectivity to the internet, and can be used by manufacturers who are looking to add wireless connectivity to machine-to-machine (M2M) applications, such as home appliances,

Murata Wireless Solutions (MWS), a manufacturer of wireless modules, on Tuesday announced the introduction of its Wi-Fi Network Controller Module.  The SN8200 is a small, low power, self-contained, certified Wi-Fi network controller module that provides serial-to-Wi-Fi connectivity to the internet, and can be used by manufacturers who are looking to add wireless connectivity to machine-to-machine (M2M) applications, such as home appliances, healthcare equipment, industrial control, and monitoring applications. 

The SN8200 is enabled with Broadcom Corporation’s (Irvine, Calif., USA) Wireless Internet Connectivity for Embedded Devices architecture.  It hosts 11n Wi-Fi, TCP/IP network stack, security supplicant and other network application features, such as web server, all integrated within the module, says Murata.  It provides Murata’s Simple Network Interface Card (SNIC) serial-to-Wi-Fi interface protocol that treats the Wi-Fi module as a simple serial port.  This reduces the development and integration effort for design engineers and shortens time-to-market, says the company.

The SN8200 module is FCC and IC Certified and is compliant with ETSI standards EN 300 328 and EN 301 489.  

The SN8200 includes the latest and most advanced IEEE 802.11b/g/n Wi-Fi system-on-chip from Broadcom and an STM32 32-bit ARM Cortex M3 microcontroller from STMicroelectronics that hosts the networking application and provides the network stack and Wi-Fi API.  The module also combines a diversity enabled RF front end, PMU and on-board antenna, says Murata.

The SN8200 is the first module from MWS’s Network Controller Module product line.  The family is comprised of footprint compatible modules with flexible software personalities and hardware configurations.  Variants include antenna diversity, microcontroller speed, flash memory size, peripheral interfaces and advanced software feature options like access point mode, Wi-Fi Direct, Smart Energy Profile 2.0, and IPv6, says the company.

“Wi-Fi has become ubiquitous, with 1.1 billion enabled devices shipped in 2011. An easy-to-integrate, low power Wi-Fi module that leverages features such as advanced security and network stacks can help manufacturers connect smart devices and sensors in the home, office or industrial environments,” said Alex West, Research Director of IMS Research.

The SN8200 Serial-to-Wi-Fi Network Controller development kits are available for $199.  The SN8200 module is priced in the mid to high teens.
