The main purpose of this thesis is a presentation of different communication technologies for Public Protection and Disaster Relief (PPDR) and possibility of their use. Fourth generation mobile networks LTE are currently one of the most developed technologies in the world of mobile communications which are already available for commercial use. Because of the potential these mobile communications have for PPDR purposes, I will focus more on this generation mobile networks. In the following sections below I talk about the advantages / disadvantages of that technologies over LTE, PPDR services and flexible harmonization of radio spectrum for broadband PPDR.
For easier understanding of the entire contents I initially pointed out a brief history of the development of technologies in different mobile networks. In the following I am concentrating mainly on the technologies operating modes over LTE. Through a case in the fifth chapter, I also want to present the practical operation of public safety communications and and in the end I will conclude with final thoughts about my thesis.
