Green solutions for future LTE PMR networks

In this paper we propose different green solutions for adapting the Long Term Evolution (LTE) technology to the Professional Mobile Radio (PMR) requirements. The PMR networks, currently using second generation (2G) technologies, have to evolve to new broadband solutions in order to satisfy their target user demands. The energy consumption is one of the critical points of the broadband solution, and an important constraint for PMR services. We propose different solutions, going from Radio Frequency (RF) level up to the MAC level, for adapting the 4G LTE technology to PMR requirements, reduce the energy consumption and increase autonomy of mobile PMR terminals.
