Broadband Radio Transmission in Railways

Carrying on the communications between onboard and wayside equipment, radio systems are widely used in railways. Higher transmission speed is being demanded for the radio system in recent years. A survey on the current situation to discover the application of radio transmission in railways is carried out in this research. Survey results include comparisons that showed that a broadband environment using Worldwide Interoperability for Microwave Access (WiMAX) is being put in place around conventional lines in the greater Tokyo area. Also conducted were transmission tests using broadband radios to clarify the technical issues of and possibilities for broadband radio transmission services on Shinkansen trains. Transmission at a rate of 4.4 Mbps is confirmed by the tests.
