Redpine Signals Launches 802.11n Wireless Sensor ModuleFebruary 19, 2009
The SenSiFi is an ultra low-power, fully integrated 802.11n single stream module that provides over 3 years of battery life for sensor devices.
SAN JOSE, CA /PRNewswire/ -- A new wireless sensor module that provides all the control and wireless functionality required to build and deploy wireless sensor nodes is now available from Redpine Signals, Inc. The SenSiFi module, designated as RS9110-N-11-31, is based on the company's ultra low-power Lite-Fi 802.11n technology to provide the benefits of ultra low-power wireless connectivity and the network capacity advantage of 802.11n to sensor networks in the industrial and enterprise arena. Redpine a leading developer of ultra low power multi-standard OFDM and MIMO silicon- based solutions for Wi-Fi, WiMAX and 3GPP LTE.
Redpine's SenSiFi wireless sensor module offers a complete foundation for building sensor applications utilizing its onboard ultra low-power microcontroller and wireless sub-system. It is able to collect a full range of telemetry information—including temperature, humidity, motion, light, pressure, location, and battery level—through standard analog and digital sensor interfaces. The microcontroller implements a small, embedded operating system on which multiple applications can be built. The fully self-contained module includes standards-compliant WLAN functionality with WPA2 security, a network stack that terminates TCP/IP and UDP connections with IPv6 capability, and configuration capability through UART or wireless. The module also includes a built-in antenna, frequency reference, power management, and flashed-in firmware. The module is available in an easy-to-assemble 31mm x 44mm QFN package.
"Our SenSiFi module is based on our proven and highly integrated RS9110 SoC, the industry's first and lowest power 11n single-stream solution," said Venkat Mattela, CEO of Redpine Signals. "Conventional sensor solutions have used a number of wireless transmission methods including Zigbee, Bluetooth, and proprietary methods, while some use legacy 802.11b/g Wi-Fi, but as enterprise networks embrace the 802.11n standard, designers need a solution such as ours that supports the requirement for all clients, irrespective of bandwidth needs, to use the 802.11n protocol," he added.
The SenSiFi module is built for extremely low power consumption using system-level and profile-driven fine-grained power control, a microcontroller with an ultra low-power mode working off a low-frequency clock source, and a WLAN subsystem with multiple power modes. With a single 3V, 2000 mAh battery, and uploading sensor data every two minutes over an IPv6 framework, the wireless sensor module can achieve over three years of battery life. The high-performance WLAN subsystem in the module further enhances range and effectiveness of data transfer, at the same time providing energy savings.
The SenSiFi module is available for evaluation through a fully implemented evaluation board that integrates temperature, humidity, and pressure sensors, an accelerometer, battery management, full-functional firmware for WLAN protocol and device control, a configuration utility, and a web-based tracking application that provides a graphical representation of sensor data. Redpine also provides sample sensor management functions on the microcontroller, along with APIs for applications development. The module is sampling now.
The SenSiFi module will be demonstrated at Redpine Signals' booth # 1606 at the Embedded Systems Conference being held in San Jose McEnery Convention Center from March 30 to April 3, 2009.
