An effective way to address this challenge is to use train-mounted antennas which simultaneously emit signals both along the direction of the train and in the opposite direction. Return radiation ensures that the train does not break off the connection with the base station even when it enters the shadow zone.
Radio Gigabit Systems has developed a special
RGA-T5 series of Wi-Fi antennas for use on the railway cars. This series features antennas that emit signals only along the direction of railway traffic, and antennas that emit in both directions (forward and reverse directions). Our unique innovative technology allows to keep the level of the reverse radiation of the
RGA-T5-14 bipolarization antenna at about -10 dB, which ensures that the train does not disconnect from the base station even in the shadow zone. These antennas are already widely used in daily operation and have already proven to be effective.
The portfolio of Radio Gigabit Systems products also features antennas for base stations located along the routes. These include the
RGA-P5-19 bipolarization antenna, which can be used as the base station antenna due to its small dimensions, high gain, and high degree of protection against moisture and dust.
