Abstract
An aspect of the invention provides a method of synchronising a first clock of a first device and a second clock of a second device comprising. The method includes transmitting 302 a dummy packet from the second device to the first device over a wireless network; determining 304 a time D2 on the second clock associated to a time that the second device initiates transmission of the dummy packet; determining 306 a time D1 on the first clock associated to the time that the first device receives transmission of the dummy packet; transmitting 308 a value of D2 from the second device to the first device; and applying 310 a correction to the first clock based at least partly on a difference between D1 and D2.
