Evaluation of subscriber movement velocity influence on specific intensity of connection loss streams in networks with OFDM signals

Abstract. Relationships were found setting dependence between the connection-loss intensity in mobile communication networks with OFDM and subscriber movement velocity. It was defined that the maximum of the loss intensity occurs in lines with the most complicated modulation types (QAM64). It was found that the for less complicated modulation types (QPSK) there was no significant influence of subscriber movement. It is also shown that in the main bands of McWiLL network (300…400 MHz) the subscribers’ movement up to velocity of 100 meter/s had no impact on connection-loss intensity. At the same time, it was found for the main LTE band of 2600 MHz that the connection-loss intensity became prohibitive at velocities of 30 meter/s and higher.
