Micro Digital Announces smxWiFi Upgrade

by Bryon Moyer

Costa Mesa, California, November 16, 2009 – Micro Digital Inc. is pleased to announce that smxWiFi, first released in June of 2008, has been upgraded to support 802.11n (high speed) and additional chips sets from Ralink. smxWiFi now provides support for USB WiFi dongles using the Ralink RT2500, 2573, and 2870 chipsets. In addition, it now supports PCI bus WiFi cards using the Ralink RT2860 and 2760 chipsets. Support for other chipsets can be added.

This software package is IEEE 802.11 a, b, g, i and n compliant and supports connection to an Access Point (AP) or peer to peer connection. smxWiFi is available with or without security. For security, Open, Shared, WPA-PSK, and WPA2-PSK authentication types are supported and WEP, TKIP, and AES encryption modes are supported.

smxWiFi allows an embedded device developer to easily add wireless connectivity to an embedded device by plugging in one of the many USB to WiFi adapters or PCI bus WiFi cards available on the market that use the supported Ralink chipsets. smxWiFi operates seamlessly with the Micro Digital smxUSBH host stack, smxNS TCP/IP stack, and SMX® RTOS. Together, these products provide an out-of-the-box solution for embedded systems requiring wireless connectivity. They can also be used with other RTOS’s.

For the RT2573 chip set with x86 and ISP1761, 205 KBps has been measured. For the RT2870 chip set with x86 and EHCI, performance increases to 300 KBps. For the 2860 PCI chip set with x86, performance is 350 KBps. Security, of course, reduces these numbers considerably unless hardware cryto engines are available. With security and the RT2573 driver, the ROM requirement is about 80 KB and RAM is 25 KB. Hence, smxWiFi is well-suited to small embedded systems.

Pricing and Availability
smxWiFi is available now. The price for a single-product, royalty-free license starts at $7,000 for smxWiFia,b,g, including the RT25xx driver. WEP is $1,000 extra; WPA is $5,000 extra.

High Power Charging Inlets

Sponsored by Mouser Electronics and TE Connectivity

All major truck and bus OEMs will be launching electric vehicle platforms within the next few years and in order to keep pace with on-highway and off-highway EV innovation, our charging inlets must also provide the voltage, current and charging requirements needed for these vehicles. In this episode of Chalk Talk, Amelia Dalton and Drew Reetz from TE Connectivity investigate charging inlet design considerations for the next generation of industrial and commercial transportation, the differences between AC only charging and fast charge and high power charging inlets, and the benefits that TE Connectivity’s ICT high power charging inlets bring to these kinds of designs.
