Redpine Signals, a developer of multi-standard wireless chipsets and systems, has launched Connect-io-n series of modules, a suite of integrated single-stream 802.11n Wi-Fi IO modules that provides wireless connectivity for embedded systems.
The company claims that the Connect-io-n technology offers single-stream 802.11n modules at a smaller size, lower cost and lower power than legacy 802.11b and 802.11g modules.
According to Redpine, the products include RS9110-N-11-23, a self-contained 2.4GHz Wi-Fi client device with a standard serial or SPI interface to the microcontroller host; the RS9110-N-11-24, a 2.4 GHz Wi-Fi client device with networking stack included; the RS9110-N-11-27, a dual-band 2.4/5GHz Wi-Fi client device with a standard serial or SPI interface to the microcontroller host; and the RS9110-N-11-28, a dual band 2.4/5GHz Wi-Fi client device with networking stack included.
The company said that the Connect-io-n series is based on Lite-Fi chipset and the Connect-io-n modules have transmit power of 18dBm and receiver sensitivity down to -98dBm, 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).
Venkat Mattela, CEO of Redpine Signals, said: 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.
“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.
