要約(英語): Recently, since many wireless terminals become to be used, the introduction of small cells is considered to increase data throughput. This paper proposes allocation of indoor base stations for multiple-carrier and multiple-communication systems. The base station antenna allocation is determined by using a genetic algorithm and electromagnetic simulation based on the ray-tracing method. Evaluation of each gene, in addition to the area coverage according to the communication quality index, including the wiring cost, such as cable length and coupler number of the wiring. The novel genetic operation enables to create a gene that meets the conditions of communication areas in the building. We confirmed that how our genetic operation is effective in the case of WCDMA (Wideband Code Division Multiple Access) /CDMA (Code Division Multiple Access) 2000 1x, LTE (Long Term Evolution), and WiMAX (Worldwide Interoperability for Microwave Access).
