The RS9110-N-11-21 module from Redpine's Connect-io-n™ family of products is a complete IEEE 802.11bgn Wi-Fi client device with a standard serial or SPI interface to a host processor or data source. It integrates a MAC, Baseband processor, RF transceiver with power amplifier, a frequency reference, an antenna, and all WLAN protocol and configuration functionality in embedded firmware to provide a self-contained 802.11n WLAN solution for a variety of applications. No WLAN driver functionality is required on the host processor. Based on the Redpine Signals’ RS9110 SoC which includes an embedded processor, it is designed to provide standards compliant wireless connectivity to devices and systems that have a serial port and implement a TCP/IP stack. As a wireless serial modem, the RS9110-N-11-21 handles SLIP packets and accepts AT Commands for configuration, enabling a variety of M2M applications at low cost and small footprint. It uniquely provides connectivity in the single stream 802.11n mode, preserving overall network throughput in the emerging enterprise environments. Features : Compliant to 802.11b/g and single stream draft 802.11n Does not require any WLAN driver on the host processor Includes all the protocol and configuration functions required for WLAN connectivity in open and WPA/WPA2-PSK secure modes of operation Host interface through Serial Interface and SPI Terminates UDP and SLIP connections and offers transparent serial modem functionality Configuration through AT commands Bluetooth Coexistence support Integrated antenna, frequency reference, and low-frequency clock Ultra low power operation with power save modes Single supply 3.1 to 3.6 V operation
