Abstract: The technology relates to a wireless system that can be used indoors or outdoors, and is configured to reduce interference of beacon signals on channels used by the system. Aspects of the technology provide for evaluation of channel activity to determine an optimal transmission channel. This is beneficial where there is a high density of tags that may be configured for data transmission. Tags may include an antenna to receive signals; a set of first conditioning elements to attenuate received signals corresponding with system channels; a set of converters and a set of second conditioning elements to prepare attenuated signals for analysis; a comparator to determine which attenuated signal corresponds to a channel having the lowest power level; and a processor to transmit a beacon signal to a reader apparatus on the channel with the lowest power level.
