1. A method of facilitating data exchange, comprising:
- assigning a first specific time slot for a first client device to wirelessly communicate with a fixed proximity-based reader device, the first specific time slot set according to a first class; and
assigning a second specific time slot for a second client device to wirelessly communicate with the fixed proximity-based reader device, the second specific time slot set according to a second class,wherein the first and second specific time slots are determined based on synchronization information wirelessly received by the first and second client devices and priority level data associated with the first class and with the second class, andwherein the first class is associated with one or more of the first client device and a user of the first client device, and the second class is associated with one or more of the second client device and a user of the second client device.

Abstract
Wireless client devices within a wireless network exchange data with other wireless devices during particular time slots determined by the network. More particularly, the system generates and wirelessly broadcasts synchronization information to the client devices, where the synchronization information contains individual masks to be applied to bit fields of individual client devices, where said time slots are determined in accordance with the masked bit fields. In such a manner, client devices can be coordinated to communicate with the system in a dynamic real-time tiered manner.
