As the city's only railway network, the Metro in Bursa Turkey, provides the general public with an excellent supply for the local public transport system. On such a long route of 31 Km, a digital radio data transmission system is an essential part to guarantee the smooth operation of the railway. In 2012, Hytera replaced the existing MPT system with the latest TETRA technology.
