Most onboard Wi-Fi solutions work over commercial cellular networks. This technology requires low CAPEX but provides limited connectivity due to circumstances beyond the train operators control. For example, commercial cellular network coverage levels can vary, cellular phone users connect directly to cellular cell sites and operators also have to deal with challenging environmental elements such as tunnels and more.
Cellular based solutions require substantial OPEX that will continue to grow, together with the bandwidth demands of passengers consistently hungry for new services and applications.
RADWIN addresses these demands with a dedicated trackside radio solution that provides passengers with uninterrupted, fiber-like onboard Wi-Fi services. This type of solution minimizes OPEX and provides new monitezation opportunities when leveraging upon the infrastructure for additional applications.
