In order to identify a fault location, a fault detection method in which a base station installed in each of a plurality of sections of a route, an antenna which is connected to the base station and installed along the route, and a control device which controls all the base stations installed along the route are used comprises: measuring a strength of a signal emitted from the antenna in at least one mobile body in operation; acquiring a temporary failure determination result based on the signal strength, transmitting announcement information by the control device via the base station and the antenna to which it is determined that a failure occurs when the temporary failure determination result is acquired, transmitting an answer to the control device by the arbitrary mobile body in operation and receives the announcement information, and making a final failure determination based on the answer transmitted from each mobile body in the control device.

The present invention relates to a wireless communication arrangement comprising a node and a leaky cable running between a first and second converter arrangement. The first converter arrangement connects a first downlink signal and a second downlink signal to the cable, and converts the second downlink signal from a first frequency to a second frequency. The cable's other end is connected to the second converter arrangement which converts the second downlink signal from the second frequency to the first frequency. The second converter arrangement also converts a first uplink signal from a third frequency to a fourth frequency. The first converter arrangement receives the converted first uplink signal from the second converter arrangement and converts it from the fourth frequency to the third frequency. The first frequency is separated from the second frequency, and the third frequency is separated from the fourth frequency.

The various embodiments herein provide a system and method for providing short range wireless communication. The system comprises a transmitting end, a first electrical circuitry provided at the transmitting end to generate a propagating EM wave on a connected wire according to an input data signal, a transmitting antenna provided at the transmitting end designed to maximize scattering of the propagating EM wave, a receiving end, a receiving antenna provided at the receiving end to detect the scattered EM wave and a second electrical circuitry provided at the receiving end to recover the input data signal from the signal received by the receiving antenna. Here a wireless link is established by means of the scattered EM waves generated by near field emissions from a surface of the transmitting antenna.
