Information communication system e.g. for city guide information, compares information received from communication device with data bank information for selecting information fed back via base station

摘要

The communication system has at least one base station (2) and at least one cooperating communication device (1), each provided with a transmitter and a receiver, for bidirectional transmission of information via electromagnetic signals. Each communication device has an information input/output device and an information storage memory, each base station linked to a processor (4) for comparing information received from a communication device with information held in a data bank, to allow extraction of information for feeding to the communication device via the base station. An Independent claim for an information communication device is also included.
