In-door Base Station Systems

Improving GSM to meet low-tier challenge


In this paper the base station issues for two indoor environments, home and office, are discussed. The two environments differ greatly in their characteristics and, consequently, different solutions are needed. At homes, the key issue is the cost of the base station. To meet the low-cost requirement, a MS based HW architecture for the base station is needed. The usage of only few timeslots instead of eight will cause the air-interface to change. Two proposals for air-interface standard are discussed: Adaptive Frequency Allocation (AFA) and Total Frequency Hopping (TFH) In offices, the key issue is spectral efficiency. The GSM operators will face the challenge of providing high capacity in urban down town areas with only few carriers. Contemporary base station fail in doing it in a cost effective way. New hybrid solution, where the best parts of a single cell and multicell architecture are used, is presented.
