Abstract
A wireless synchronization device is used to coordinate the timing and activities of individual, possibly physically separated, wireless service providers with defined coverage area. Further, the synchronization information is used to coordinate the timing and activities of portable wireless client devices in an autonomous, wireless proximity sensing and data transfer network. Moreover, one or more of the wireless service providers can be arranged to simultaneously monitor broadcasts from the wireless synchronization device and communicate with one or more of the portable wireless client devices.
