This chapter illustrated the impact of network architecture on EMF exposure of a person and of the population in an area. The main factors shaping the EMF exposure are technology used, radio conditions and network load conditions, along with the service used under these circumstances. Network architecture, i.e. technology and topology used for an area, with the set of network policies, determines network behaviour for given traffic fluctuations in the area and radio and network conditions for every single user. In this complex environment with constant and instant changes and mutual dependencies between factors affecting the EMF exposure, statistical analysis may be performed and some conclusions drawn.
