Driven by the development of wireless networks, wireless technologies have been integrated with rail transport. The wide availability of smartphones further boosts demand for wireless connections. Wireless networks such as Wi-Fi, 3G, and 4G LTE have penetrated into every aspect of our lives. However, in-vehicle wireless communications require higher standards in order to cope with severe electromagnetic interference and long-term vibration in harsh environments.

ORing has developed a series of EN50155-compliant 3G/4G cellular routers and access points boasting high performance and reliability. The wide variety of products, as shown in the following table, aims to address the needs of different rolling stock applications. Featuring built-in IEEE 802.11a/b/g/n connectivity, these devices are able to provide long-haul transmission, roaming, and wireless redundancy. In addition, the devices support several communications standards including GSM, GPRS, HSDPA, and 4G LTE. The compact design with a small footprint means the devices are space-efficient.

Apart from 4G LTE support, the next generation of wireless technology, the TGAR-2062-3G/4G cellular router provides two SIM card slots. When one SIM card fails, the other one will be activated immediately to provide network redundancy, thereby reducing the risk of system downtime. The leading-edge TGAR-1662-3G/4G cellular router can operate on either the 2.4GHz or 5GHz band. All of ORing’s industrial routers for rolling stock applications provide a wide temperature range of -25 to +70oC, making them the best choice for our customers. In addition to the rolling stock-oriented products, ORing’s newly launched standard industrial routers have also seen brisk sales.
