<p>The device has a central radio network-control device (11) and two radiocell devices (10) for common wave-radio communication of digital signal based terminal. Two radiocell devices are provided for digital coded radio signals, and stay with the control devices for synchronized radiation of the digital receiving signals of the terminal received by the radiocell devices over communication connection (12) in a controlled communication. The digital receiving signals of the terminal are received by the radiocell devices. Independent claims are also included for the following: (1) a method for operating the terrestrial trunked radiocommon-wave-radio network device; and (2) a method for upgrading of an existing analog common-wave-radio device in a terrestrial trunked radio network device.</p> |
