1. A method for radio frequency identification tracking, comprising:
- transmitting a first radio frequency identification signal by a first radio frequency identification reader to a first group of passive radio frequency identification tags;
receiving at the first radio frequency identification reader first data from the first group of passive radio frequency identification tags in response to the first radio frequency identification signal;
transmitting the first data by the first radio frequency identification reader to a gateway radio frequency identification tag;
transmitting a query by the first radio frequency identification reader requesting second data from the gateway radio frequency identification tag, wherein the second data was previously transmitted to the gateway radio frequency identification tag by a second radio frequency identification reader; and
receiving the second data from the gateway radio frequency identification tag by the first radio frequency identification reader.

Abstract
A system and method are disclosed for transporting deterministic traffic in a gigabit passive optical network. A system that incorporates teachings of the present disclosure may include, for example, an Optical Line Termination (OLT) for exchanging data traffic in a Gigabit Passive Optical Network (GPON) having a controller programmed to generate a timeslot schedule for transport of a desired bandwidth of constant bit rate (CBR) data traffic by selecting one or more timeslots from periodic frame clusters operating according to a GPON Transmission Convergence (GTC) protocol. Additional embodiments are disclosed.
