Micro Digital Offers Full USB WiFi Support

Costa Mesa, California, August 31st, 2010 --- 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.   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 (personal), WPA-EAP (enterprise) and the similar WPA2 protocols. For encryption, smxWiFi supports WEP, TKIP, and AES.   smxWiFi supports the Ralink RT2573, RT2870, RT3070, and RT2760 chipsets, which are extensively used in USB WiFi adapters. These provide an easy, low-cost way to add WiFi to an embedded system and they work with the smxUSBH USB host stack. smxWi also supports the Ralink RT2860 PCI chipset, which is available on many PCI cards. This chipset is supported directly by smxNS without smxUSBH being required.
