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.enbandwidthinformation networkmobile communication networkSpace Division Multiple Accessadaptive antenna systemMultiple Input Multiple Outputantenna patternArticle
