IRD62/E mobile radio repeater as center of a cell in the single-sight/multi-sight radio network under the DMR Tier standard with capability of high reliability and analogue/digital facilities is proper to establish an advanced full digital communication. This repeater can be operated in both analogue and digital modes, since it is compatible with available analogue networks. IRD62/E automatically switches between analogue and digital modes, based on the type of the received signal.
On the whole, in civil radio networks, vehicular/rack-mount digital repeater is considered to establish reliable and high quality communication for covering more operators and exchanging vital and online information.
