DescriptionAs a common transportation, Railways transportation increases the carrying capacity, shortens the transportation time and decreases the transportation cost which improve the quality of transportation services, yield greater customer satisfaction, and help to create the socioeconomically balanced societies. And this highly efficient transport mode creates significant challenges in terms of investment, technology, industry, and environment.
Railway radio communication which offering voice or data services needed for daily operation. Various radio communication system/technology have been used for many years for railway operational applications, such as analog radio, digital radio, TETRA, GSM-R, LTE-R are used for railway communication. Radio communication networks are critical to train operations including stringent requirements for reliability, availability, safety and security for these operations.
Helios® Single Band Digital Optical Transport System is designed to integrate single band systems and extend the coverage of Public Safety Radio and Commercial Cellular into large Public Venues, such as Hospitals, Hotels, Shopping Malls, Office Buildings, long Tunnels sections and large area outdoor coverage.
