smxWiFi Supports Ralink RT5370 Wireless Chipset

Costa Mesa, California, May 17, 2011 — smxWiFi™ now supports the Ralink RT5370 chipset used in USB WiFi adapters. smxWiFi supports all current Ralink USB WiFi chipsets:  RT2573, RT2870, RT3070, RT3572, and RT5370, and it supports the RT2760 PCI chipset. For maximum flexibility, all can be purchased and used in a system, and the proper one is selected at run-time when the WiFi adapter is plugged in.

smxWiFi provides the necessary software to easily add wireless connectivity to an embedded system. It is a robust, 802.11 Media Access Control (MAC) stack specifically designed and developed for embedded systems. (An 802.11 network is a wireless local area network (WLAN) that conforms to the 802.11 standards.) smxWiFi conforms to 802.11 a/b/g/i/n. It is a mature product, released in June 2008.

Due to the complexities of the 802.11 protocol, smxWiFi requires a multitasking environment; for this, it has been integrated with our SMX® RTOS. A TCP/IP stack is also required; for this it has been integrated with our smxNS™ TCP/IP stack. smxWiFi is written in C. It can run on any hardware platform and can be easily ported to another RTOS and/or TCP/IP stack.

WiFi ordinarily requires a high level of security. There are two aspects of security. One is the Authentication Type and the other is the Encryption Algorithm/Protocol. For authentication, smxWiFi supports WPA, WPA-PSK, and the similar WPA2 protocols. For encryption, smxWiFi supports WEP, TKIP, and AES.
