N2 - In this work, we analyze the deployed Releases of Long Term Evolution (LTE) technology, their advantages and drawbacks. Based on the existing Releases, from 5 to 10 [1, 2], we put a question on how to integrate the advanced LTE technology and multiple-input-multiple-output (MIMO) system for multi-user (MU) multiple access deployment, which we call the Advanced LTE Release 10/MIMO network. We analyze this integrated network in order to increase the communication capacity. We take into account multi-parametric stochastic approach that combines the statistical description of the terrain and the built-up overlay with description of the signal intensity spatial distribution, taking into account the channel multipath effects from various natural and artificial obstructions located in the urban scene. The Rician K-parameter is used for multiplicative noise description, as a ratio of the coherent and incoherent components of the signal intensity [3]. Using the K-factor spatial distribution depending of the features of built-up terrain, an information data stream both for MIMO correlated antennas (the good case) and uncorrelated MIMO antennas (the worst case), as well as the capacity and spectral efficiency are predicted, depending on the 'reaction' of different kinds of the terrestrial channel - rural, mixed residential, rural and urban. Finally, we give practical recommendations of how using the proposed combined LTE/MIMO Network with a Multi-beam antenna system will increase the system's capacity. This will allow the designers of wireless networks to obtain maximum data rate, better channel spectral efficiency and less bit error rate, and as a result, much better service and transmission performances.
