Abstract: A method of estimating the distance between a first wireless communication terminal and a second wireless communication terminal includes: (i) receiving at the first terminal a received signal comprising a composite multipath derivative of a RF transmission signal transmitted by a second terminal which transmission signal comprises an OFDM signal; and (ii) processing the received signal including performing a demodulation operation to produce a demodulated signal; and characterised by: (iii) resolving the demodulated signal into a plurality of components corresponding to different path length components included in the received signal; (iv) identifying which of the resolved components corresponds to a shortest path length; and (v) for the identified component, computing a time of travel from the second terminal to the first terminal. the first terminal may be operable to determine a strength value for each of the resolved components. The strength value may be compared with a threshold value to determine if the strength value is to be considered as non-zero, whereby the component having that strength value is to be included to find the component having the shortest path length. Also described is a terminal which operates to carry out these steps and a method of transmitting and receiving an OFDM signal which includes these steps. The transmitted signal which is transmitted by the second terminal and received in a multipath derivative form by the first terminal may conveniently be the PLCP (Physical Layer Convergence Procedure) Training Signal defined in the 802.11 standard. This is the 'Long Training Sequence' normally provided at the beginning of a transmission by a terminal in a LAN (e.g. a RU). The purpose of this signal is to allow another terminal (e.g. an AP) to synchronize with the terminal.

Abstract: A method and apparatus of operation of a mobile communication system comprising at least one mobile station is disclosed. The method and apparatus comprise storing in a database information relating to coverage areas of a plurality of wireless networks and monitoring the mobile station for its location while the mobile station is connected to a serving network. The method and apparatus then require comparing the monitored location of the mobile station with the stored coverage area information to produce an alert signal in the mobile station which indicates to the mobile station that one of the wireless networks is nearby. The method and apparatus then initiate a procedure to handover connectivity from the serving network to a nearby network, wherein the serving network and the nearby network use routing address protocols which have a common internet protocol (IP) address routing portion.
