University of Missouri--Kansas City, 2017Mission-critical communication is one of the central design aspects of 5G communications. But there are numerous challenges and explicit requirements for development of a successful mission-critical communication system. Reliability and delay optimization are the two most crucial among them. Achieving reliability is influenced by several difficulties, including but not limited to fading, mobility, interference, and inefficient resource utilization. Achieving reliability may cost one of the most critical features of mission critical communication, which is delay. This thesis discusses possible strategies to achieve reliability in a mission-critical network. Based on the strategies, a framework for a reliable mission-critical system has also been proposed. A simulation study of the effects of different pivotal factors that affect communication channel is described. This study provides a better understanding of the requirements for improving the reliability of a practical communication system.Introduction -- Related works -- Case studies for mission critical communication -- Strategies to achieve ultra-reliable M2M -- Adaptive mimo system with OSTBC -- Simulation results -- Conclusions and future aspect

Reliable communication between rescuers during interventions using textile antenna systems

The safety of on-duty firefighters in indoor environments could be increased by ensuring reliable, high-data rate communication in potentially life-threatening situations. This increases their situational awareness, strengthens their decision making and decreases response time by ensuring efficient indoor communication of sensor data, biometric data, pictures or videos. Therefore, a real-life rescue operation was replicated by means of two simultaneously moving firefighters in an office environment. These wideband channel sounder measurements were performed at 3.6 GHz with 80 MHz bandwidth. Four Ultra-Wideband Substrate Integrated Waveguide cavity-backed slot textile antennas were integrated in the front, back, left shoulder and right shoulder sections of the firefighters' jackets, providing up to 4x4 MIMO communication. For this indoor environment, we extract the pertinent OFDM parameters using the RMS delay spread and 50% correlation bandwidth of the sixteen individual SISO channels. Furthermore, we calculate the potential SISO-, 2 x 2 MIMO-and 4 x 4 MIMO-OFDM capacities and corresponding data rates. Finally, we show that the 4x4 MIMO setup is more energy efficient and increases both the link reliability and link quality
