Connectivity on the Trains

Orange Polska said travelling by train is the perfect time to watch movies or work, and a few hours can be spent in a pleasant and effective manner. Of course, this can only be possible as long as users are within a mobile network coverage zone. Therefore, Orange has taken the initiative to install amplifiers in train coaches to enhance connectivity inside trains.

Signal Amplifiers

Orange said cellular network signal amplifiers, known as repeaters, are installed to facilitate the transmission of radio signals between base stations and consumer devices that utilise the mobile network. This setup and solution are employed to enhance the signal and extend the coverage range.

Technology Behind Signal Amplifiers

In the case of trains, special donor antennas are affixed to the roofs of the wagons, receiving signals from the base station. These signals are then transmitted via coaxial cable to the repeater, where they are amplified, and subsequently, the strengthened signal is conveyed through leaky coaxial cables extended along the wagons, ensuring radio signal coverage throughout the length of the train.

Orange reported that in October, PKP Intercity launched amplifiers in 300 train cars, with another 254 planned to be installed by the end of this year. These amplifiers are also equipped with GPS receivers to ensure they can be remotely monitored and configured based on their location. The GPS facilitates insights into the dynamic nature of traffic and users on a moving train.
