Представлен подход к формированию порядка определения и применения показателей и индикаторов стадий жизненного цикла поколений сетей подвижной связи (СПС) в их эволюционном развитии. Подтверждена необходимость использования этих инструментов в решении прикладных вопросов регуляторного, нормативно-правового и других видов обеспечения для упреждающей разработки мероприятий, обуславливающих возможность внедрения СПС с учетом сложившихся национальных регуляторных процедур. Показана взаимообусловленная связь и приведено соотношение поколений СПС с поколениями социотехнических систем. An approach to the formation of the procedure for determining and applying indexes and indicators of the stages of the life cycle of generations of cellular mobile communication networks in their evolutionary development is presented. It is shown that it is necessary to use these indexes and indicators in solving applied issues of regulatory and other types of support to enable the proactive development of measures that determine the possibility of implementing the mobile networks, taking into account the existing national regulatory procedures. A mutually dependent relationship is presented, and the ratio of generations of mobile communication networks with generations of socio-technical systems is given.

For today's cellular mobile communication networks, the needed capacity is hard to realize without much more of (expensive) bandwidth. Thus new standards like LTE were developed. LTE advanced is in discussion as the successor of LTE and cooperative multipoint transmission (CoMP) is one of the hot topics to increase the system's capacity. System simulations often show only weak gains of the signal-to-interference ratio due to high interference from noncooperating cells in the downlink. This paper presents an interference mitigation framework to overcome the hardest issue, that is, the low penetration rate of mobile stations that can be served from a cluster composed of their strongest cells in the network. The results obtained from simulation tools are discussed with values resulting from testbed on the TU Dresden. They show that the theoretical ideas can be transferred into gains on real systems.

This work reviews the main related problems of electromagnetic compatibility (EMC) of the locomotive radio system GSM-R in modern railway transport. The typical internal electromagnetic interference (EMI), caused by the high density of the equipment layout in the rolling stock, and external electromagnetic interference generated by public cellular mobile communication networks and other radio systems are considered. The results of experiments to determine the parameters of public cellular mobile communication networks along the selected railway section show a rather high level of signals that are EMI for GSM-R and affecting on EMC.
