Abstract
A location estimation system includes non-directional stationary devices having respective non-directional antennas configured to receive a radio signal transmitted by a mobile device; and directional stationary devices having respective directional antennas configured to receive a radio signal transmitted by the mobile device. The non-directional stationary devices output, as pieces of location estimation information for estimating a location of the mobile device, pieces of information indicating received signal strength indicators of the received radio signal. The directional stationary devices output, as pieces of complementary information for identifying a non-directional stationary device used for location estimation from among the non-directional stationary devices, pieces of information indicating received signal strength indicators of the received radio signal.
