CarTel Communications is a dynamic, well established company at the forefront of mobile communications technology. Established in 1983 CarTel has grown rapidly to become one of the Midlands leading suppliers of two-way radio, mobile data, trunked radio systems, and fleet vehicle tracking providers.
Digital PMR radio offers a host of new innovations and features for the radio user. Digital transmissions offer much clearer “interference free” communications and cannot be “eavesdropped” with a radio scanner making the conversations far more secure.
The Kenwood Nexedge® and dPMR systems occupy half the space of a conventional analogue signal so licensing costs are much reduced.
DMR (Digital Mobile Radio) uses a 2 slot TDMA (time division multiple access) system which can provide 2 simultaneous independent conversations. A single DMR repeater will re-transmit both signals simultaneously. DMR repeaters can also be inter-connected to another repeater in a different location using IP (internet protocol) connectivity to provide extra coverage.
Digital radio also incorporates “radio addressing” so that a single radio or any group of radios can be called.
Nexedge® and DMR (tier 3) both have trunking modes which provide a digital equivalent to MPT1327 trunked radio for cutting edge applications.
