It increases the capacity and speed using a different radio interface together with core network improvements. The goal of LTE is to increase the capacity and speed of wireless data networks using new digital signal processing techniques and modulations that were developed around the turn of the millennium. Some manufacturers are using LTE/ DMR/ Tetra multimode devices to incorporate rich broadband technologies while ensuring that critically important voice services remain accessible using multimode smart devices.
