Indoor location technique for 2G and 3G cellular/PCS networks

Although many outdoor location techniques have been proposed, there is no cost-effective indoor location technique. This paper presents a practical indoor location technique applicable to all 2G and 3G cellular/PCS indoor systems. Two typical indoor cellular/PCS architectures are considered. Recommendation for how to deploy the indoor location system with respect to each architecture is given. Simulation has been performed to validate the proposed concept. Also discussed is how to design a cost-effective indoor base station considering location service as one of the critical requirements.
