During the emergency (1948-1960), there was a strong focus on providing communications links for the police and armed forces. This included the installation of radio stations in the jungle as well as very high frequency (VHF) radiotelephony over the normal state network. By 1953, all hill stop stations required for the police VHF network were completed, enabling every police station and police vehicle to communicate with headquarters and with each other. The police radio services were thought to be the largest scheme of its kind in the world.
