Spatial Methods for Increasing the Bandwidth of a Mobile Information Network

In the presented work, a comparative analysis of the bandwidth of information networks of mobile communications is carried out, with a change in the frequency resource of the network and the spatial selectivity of the antenna systems of base stations. It was shown that the use of adaptive antenna systems at the base station allows to achieve a significantly larger increase in network bandwidth compared to an increase in the frequency resource. It is also possible to implement parallel data reception with simultaneous suppression of interfering signals and to coordinate the maximum coverage area of the base station both in the downlink and in the uplink. This allowed us to propose methods to increase the bandwidth of the information network, based on spatial and random methods, in which complex signals are used to coordinate the energy budgets of the downlink and uplink.
