Moxa's New Dual-RF Wireless Technology Enables Reliable Train-to-Ground Communications for Brazilian Railway


Taipei, Taiwan, Aug. 11, 2010—Moxa's next generation AWK-6222 and AWK-5222 dual-RF wireless AP/Bridge/Clients were chosen to create train-to-ground communication networks in Sao Paulo, Brazil's largest city.

In this project, industrial-grade WLANs are responsible for on-board video surveillance, passenger information systems, and train control, which are important components in ATO (Automatic Train Operations) and ATC (Automatic Train Control). Moxa's wireless networks allow rail operators to share real-time information between trains, OCC, and station to provide immediate status updates and emergency controls. This network is located aboveground in a busy urban area, where there is a great deal of wireless interference. In response, Moxa's next generation dual-RF modules, the AWK-5222 and AWK-6222, come with dual-band operations to allow the simultaneous use of two distinct channels to prevent transmission interference.

“Major concerns for wireless adoption in railway automation are reliability and security,” said Jackie Shi, senior manager of Moxa Industrial Wireless division. “Passenger safety and highly available connectivity are top priorities to create reliable and capable train-to-ground communications. Fortunately, Moxa’s proprietary wireless redundancy technology is designed for railway industries and offers a full suite of industrial WLAN products with dual RF redundancy, fast Turbo Roaming, wide operating temperature, WPA/WPA2, IEEE 802.1X authentication, as well EN50155 and EN50155/50121 certifications to provide outstanding wireless reliability and complete wireless network security for railway applications.”
