الملخصIn this chapter, Long Term Evolution (LTE) for public safety is investigated. Particularly, Distributed Antenna Systems (DAS) are studied, and their impact on LTE public safety networks is analyzed. Furthermore, resource allocation algorithms for the purpose of real-time video transmission, in both the Uplink (UL) and Downlink (DL) directions, are proposed, and a proportional fair scheduling algorithm, applicable in both the UL and DL directions, is presented. The proposed algorithms are compared in several scenarios with and without distributed antenna systems. In addition, Quality of Experience (QoE) metrics are used to measure the quality of the video transmissions, and joint uplink/downlink quality metrics, tailored to video transmission over public safety networks, are presented. Simulation results show large enhancements in video quality due to the application of DAS with smart resource allocation in LTE public safety networks.
