GHI's .NET Micro Framework modules, such as EMX and ChipworkX, provide WiFi support through RS9110-N-11-21-01 WiFi module. This allows for real "Socket" connection over WiFi for example with EMX module you can open up to 127 TCP/UDP sockets simultaneously with SSL security. This is not a simple WiFi-Serial bridge commonly used on simple embedded systems.
This module from Redpine's Connect-io-n™ family is a complete IEEE 802.11bgn WiFi client device with a standard 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.
Features
• Compliant to 802.11b/g and single stream 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 SPI
• Integrated antenna, frequency reference, and low-frequency clock
• Ultra low power operation with power save modes
• Ad-hoc and infrastructure modes for maximum deployment flexibility
• Single supply 3.1 to 3.6 V operation
• Certification : Module is based on RS9110-N11-02 which is certified by FCC, IC and CE.
GHI Electronics offers WIFi RS21 Module with UEXT Expansion to evaluate this WiFi module with the available GHI's .NET Micro Framework Development Systems and ODMs.
