The novel concept of single path multiple access (SPMA) using new advanced antenna technology

The aim of this paper is to introduce a novel frequency reuse concept especially for macro cellular networks to substantially increase mobile network capacity, and simultaneously to avoid the implementation of low efficient small cells. Single path multiple access (SPMA) utilizes the characteristics of independent propagation paths for particular geographical location in the coverage area of mobile network. In SPMA concept, a communication between base station and mobile station happens through single independent propagation path, and the frequency resources can be reused in 5m × 5m areas, or even more often in 1m × 1m areas. Thus, the capacity of the network will be increased dramatically, and it can be managed in centralized manner at certain macro site locations. In already deployed cellular networks, these macro sites are mostly easily available, and that would help to implement SPMA to enhance the network capacity. Simulation results provided in this paper show the applicability of single path multiple access technique, by limiting the radiation of signal as single path propagation between base station and mobile station.
