Abstract

Some demonstrative embodiments include apparatuses, systems and/or methods of communicating positioning transmissions. For example, an apparatus may include a controller to control at least one light transmitter to transmit from a mobile object Intensity-Modulated (IM) optical signals including On-Off-Keying (OOK) signals of one or more positioning transmissions, the controller is to control the at least one light transmitter to transmit from the mobile object one or more first OOK signals over a first ranging frequency, and to transmit from the mobile object one or more second OOK signals over a second ranging frequency, the second ranging frequency is different from the first ranging frequency.
