A method of obtaining timing information between first MS and second BS devices is discloses together with methods of ranging using said timing information and devices for the same. The method of obtaining timing information comprising the steps of transmitting a timing signal from the first device MS to the second device BS at a time t1 relative to the local clock of the first device MS and measuring the time of arrival t2 of that signal at the BS second device relative to the local clock of the second device BS; transmitting a timing signal from the second device BS to the first device MS at a time t3 relative to the local clock of the second device BS and measuring the time of arrival t4 of that signal at the first device MS relative to the local clock of the first device MS; and assembling the values of t1, t2, t3 and t4 in one of the devices.
A method of obtaining timing information between first and second devices comprising the steps of:
A device comprising a transmitter, receiver and processor adapted to receive and measure the time of arrival t1 relative to its local clock of a timing signal transmitted by another device;
A device adapted comprising a transmitter, receiver and processor adapted to transmit at a time t1 relative to its local clock a timing signal to another device;
