Terrestrial broadcast has traditionally targeted TV receivers in the home. But today’s most popular screens are those of SmartPhones and Tablet PCs. (Painful) Experience has shown that in order to reach those gadgets, IEEE- and 3GPP-specified solutions are required. Starting with TOoL+, the authors have proposed bridges between traditional broadcast and today’s wireless connectivity. Within the set of specifications of 3GPP such bridges named MBS, MBMS, and FeMBMS now exist – with limited acceptance by cellular network operators so far. The rapidly growing number of popular data services to SmartPhones, connected cars, etc., and 5G New Radio may change this in the future. Therefore, this paper presents a broadcast extension of today’s 5G New Radio supporting the implementation of High Tower High Power/Medium Power Medium Tower networks overlaying cellular networks. The extension was implemented using software defined radio and tested in a real-world field trial in Germany. [ABSTRACT FROM AUTHOR]

A hybrid mobile communication network as considered in this paper consists of a point-to-point network (UMTS) and a point-to-multipoint network (DVB-H). The benefit of combining these two networks is an optimized transfer of data by collecting several user requests for a single response via the broadcast network. Thus, capacity can be saved, UMTS cells can be unloaded and the mean response time of the system can be reduced. Besides these advantages, hybrid networks can be applied to decrease electromagnetic exposure, especially at hot spot areas. In this paper, it is analysed how the hybrid network structure influences the electromagnetic exposure. Therefore, different scenarios have been developed consisting of different user behavior and different network structures. In order to evaluate the grade of exposure, criteria have been defined. These criteria have been used for comparing a hybrid network with a single UMTS network in terms of electromagnetic exposure. The results are shown for the different network structures and network configurations. [ABSTRACT FROM AUTHOR]
