Every year around 200 million people are affected by hazards of different nature. In most of these situations public protection\nand disaster relief personnel are usually the first responders to provide help. To provide differential relief coverage in these\nscenarios, novel communication and network functionalities are being demanded, relegating todayâ??s narrowband private radio\n(PMR) emergency systems to the background.These are data-support, increased coverage, broadband communication, and high\nreliability which will be addressed by novel communication technologies such as Long Term Evolution (LTE), LTE Advanced-pro,\nand future 5G. In this work we tackle two key technological solutions for future emergency communication networks such as\nan architecture based on relay nodes and enhanced user equipment by means of multiple-input-multiple-output (MIMO) techniques.
