Redpine Signals Releases Industry’s First Future-Proof, Seamless 802.11n Wi-Fi(R) IO Connectivity for Embedded Systems
SAN JOSE, Calif., Dec. 15 /PRNewswire/ — Redpine Signals, Inc., a leading developer of ultra low power multi-standard wireless chipsets and systems, today announced the launch of its Connect-io-n(TM) series of modules, the industry’s first suite of highly integrated single-stream 802.11n Wi-FiÃ‚® IO modules to provide future-proof wireless connectivity for embedded systems, particularly those involved in connecting the Internet of Things. Redpine’s Connect-io-n technology offers self-contained single-stream 802.11n modules at a smaller size, lower cost and lower power than legacy 802.11b and 802.11g modules. Priced below many 802.11b/g modules, the Connect-io-n series removes the last barrier to widespread adoption of the 802.11n standard.
The products include the RS9110-N-11-23, a self-contained 2.4 GHz Wi-Fi client device with a standard serial or SPI interface to the microcontroller host, the RS9110-N-11-24, a fully contained 2.4 GHz Wi-Fi client device with networking stack included, the RS9110-N-11-27, a dual-band 2.4/5 GHz Wi-Fi client device with a standard serial or SPI interface to the microcontroller host, and the RS9110-N-11-28, a dual band 2.4/5 GHz Wi-Fi client device with networking stack included.
Wireless connectivity for embedded devices is typically characterized by low throughput, low power consumption, and relaxed latency requirements. However, Wi-Fi embedded devices are seen in ever greater numbers in a variety of environments, many of which are 802.11n-based. Legacy 802.11b/g devices and 802.11b devices in particular, cause considerable disruption to an 11n network. First, they occupy the airways far longer to transmit a given amount of information than other nodes in the network. Second, they force the Access Point — and all nodes on the network — to adopt bandwidth-consuming protection mechanisms to accommodate the legacy device. The explosive growth in adoption of Wi-Fi into embedded devices has prompted major industry groups, such as the Wi-Fi Alliance, to start disallowing 802.11b devices in upcoming certification programs such as Wi-Fi Direct. (Wi-Fi Direct is the groundbreaking specification from the Wi-Fi AllianceÃ‚® to support direct Wi-Fi connections between devices).
Redpine’s modules are the first in the industry to bring single-stream 802.11n connectivity to standard 8-bit microcontrollers. Aimed at plug-and-play integration of Wi-Fi into such platforms through an SPI or UART interface, these modules are available in software variants that can either provide a built-in TCP/IP stack or enable the use of the microcontroller’s networking stack.
The Connect-io-n series is based on Redpine’s mature Lite-FiÃ‚® chipset, the industry’s first Wi-Fi certified 802.11n single-stream device, which has been successfully integrated into a significant number of embedded systems over the past two years. Connect-io-n modules have best-in-class transmit power of 18dBm and receiver sensitivity down to -98dBm, enabling excellent range. With shutdown power of less than 0.01mW, associated mode power of less than 3mW and active operational power of less than 30mW (UART 115K baud), the Connect-io-n series enables ultra-low-power wireless battery operated applications, such as wireless sensors, with battery life of greater than 10 years and update rates faster than once in 15 minutes.
The module is small at 11mm x 13mm and it is FCC/IC/CE certified. This means that the system integrator’s task is simplified when integrating it into an embedded system. The Connect-io-n family is also the first in the industry to offer variants that support dual-band 2.4/5GHz band operation for serial-to-WiFi applications that demand better reliability and QoS in crowded wireless environments.
“Our experience has shown that single-stream 802.11n always results in lower energy consumption, independent of the data rate at which a device communicates. The reason is that the 802.11n device is on air for a shorter time and hence uses up less network bandwidth and less energy per bit,” said Venkat Mattela, CEO of Redpine Signals. “Redpine’s 802.11n Connect-io-n technology provides lower-cost, lower-power wireless connectivity to any device, with or without a TCP/IP stack. At the same time, it future-proofs the customer’s investment into the wireless solution,” he added.
Price and Availability
The technology maturity of the Lite-Fi chipset and high levels of integration of the Connect-io-n modules enable Redpine to offer the modules at lower cost than competing legacy 11b or 11g modules. The Connect-io-n single-band (2.4GHz) modules are available now and are priced at less than $19 in volumes of more than 1000 units. Evaluation kits are available for $195.
