A method of wireless communication, via a network, of occurrence of an exception event to a vehicle locating unit and at least one of a plurality of peripheral devices (PD1, PD2) linked to the a vehicle locating unit, the method comprising: - determining a location and a temporal point of occurrence of the exception event; - reserving a unique data transfer period for each source of detected transmission signals, wherein the unique data transfer period comprises N number of timing periods of equal temporal length and having a first boundary and a second boundary, wherein N is an integer greater than one and the N number of timing periods of the unique data transfer period are delineated between a unique first boundary and a unique second boundary that no other peripheral device have; and if the location of the occurrence of the exception event occurs in the vehicle locating unit, the method further comprises: - transmitting a data package from the vehicle locating unit to the corresponding source of detected transmission signals at a next unique boundary if the exception event occurs within one timing period of the next unique boundary, otherwise transmitting the data package at a next timing period boundary; and if the location of the occurrence of the exception event occurs in any of the plurality of peripheral devices (PD1, PD2), the method further comprises: - reserving a discrete time slot (81, 83, 85, 87, 91, 93, 95, 97) during the unique data transfer period for the purpose of data communication, wherein the discrete time slot (81, 83, 85, 87, 91, 93, 95, 97) is unique to the corresponding peripheral device that is the source of detected transmission signals; and - transmitting an exception occurrence signal from the corresponding peripheral device that is the source of detected transmission signals to the vehicle locating unit during the reserved discrete time slot (81, 83, 85, 87, 91, 93, 95, 97) of the corresponding peripheral device if the exception event occurs within one timing period of the next unique boundary of the unique data transfer period; otherwise - transmitting a data package (71, 73) concatenated to a shortened prolonged preamble signal from the corresponding source of detected transmission signals to the vehicle locating unit at a next timing period boundary. - determining a location and a temporal point of occurrence of the exception event; - reserving a unique data transfer period for each source of detected transmission signals, wherein the unique data transfer period comprises N number of timing periods of equal temporal length and having a first boundary and a second boundary, wherein N is an integer greater than one and the N number of timing periods of the unique data transfer period are delineated between a unique first boundary and a unique second boundary that no other peripheral device have; and - transmitting a data package from the vehicle locating unit to the corresponding source of detected transmission signals at a next unique boundary if the exception event occurs within one timing period of the next unique boundary, otherwise transmitting the data package at a next timing period boundary; and - reserving a discrete time slot (81, 83, 85, 87, 91, 93, 95, 97) during the unique data transfer period for the purpose of data communication, wherein the discrete time slot (81, 83, 85, 87, 91, 93, 95, 97) is unique to the corresponding peripheral device that is the source of detected transmission signals; and - transmitting an exception occurrence signal from the corresponding peripheral device that is the source of detected transmission signals to the vehicle locating unit during the reserved discrete time slot (81, 83, 85, 87, 91, 93, 95, 97) of the corresponding peripheral device if the exception event occurs within one timing period of the next unique boundary of the unique data transfer period; - transmitting a data package (71, 73) concatenated to a shortened prolonged preamble signal from the corresponding source of detected transmission signals to the vehicle locating unit at a next timing period boundary.
