Abstract
Some demonstrative embodiments include devices, systems and methods of synchronizing between wireless communication devices. For example, a wireless communication device may include a clock to count a local time; a controller to count a virtual master clock corresponding to a group of wireless communication devices according to master clock information defining the virtual master clock, the controller to determine a time drift between the local clock and the virtual master clock, and to determine the virtual master clock based on the local time and the time drift; and a radio to communicate with one or more devices of the group of wireless communication devices a synchronization frame including a master clock time stamp of the virtual master clock.
