Low power beacon scheduling

A method of channel selection within a tracking system comprising:

• receiving radiofrequency signals, at an antenna, from a surrounding environment;
• attenuating the radiofrequency signals at a set of first signal conditioning elements coupled to the antenna, the set of first signal conditioning elements being associated with a different channel and being configured to attenuate electromagnetic fields at frequencies of the received radiofrequency signals outside a selected frequency range for a corresponding channel;
• converting the attenuated radiofrequency signals at a set of converters each having an input operatively coupled to a corresponding one of the set of first signal conditioning elements, the set of converters each configured to convert attenuated radiofrequency signals from each corresponding first signal conditioning element into a voltage;
• averaging the converted radiofrequency signals at a set of second signal conditioning elements each operatively coupled to an output of a corresponding one of the set of converters, each second signal conditioning element being configured to output a voltage value of each converted radiofrequency signal;
• comparing, by a comparator operatively coupled to the set of second signal conditioning elements, the converted radiofrequency signals, the comparator being configured to compare the voltage value of each converted radiofrequency signal to identify whether there is one channel having a lowest power level among the different channels;
• and
• selecting a channel, by one or more processors operatively coupled to the comparator, to cause a beacon signal to be transmitted to a reader apparatus via the channel having the lowest power level.
