Sensor, a mobile user terminal and a method of a sensor sensing a mobile user terminal

Abstract:In this invention, a method for broadcasting a common signal at distinct carrier frequencies is provided. The method comprises: means for broadcasting a common signal at each of multiple carrier frequency bands; the user terminal receiving the signal in the associated carrier frequency band of its network; the user terminal checking information in the received signal, and upon determining that the information is acceptable to allow connection to the sensor, the user terminal acknowledging to the sensor its receipt of the signal. The main idea centers on:

1. A single baseband signal, multiple carriers. TX – base band signal is replicated. RX – multiple carriers are combined onto a single carrier and presented for baseband processing as a single signal.
2. Baseband signal’s PLMN set such that it is acceptable to the UE. E.g. equivalent PLMN (EPLMN) or virtual PLMN
