Patent abstract
A method, apparatus, and system for periodically measuring the level of ambient noise found on a radio frequency channel used by a radio frequency identification interrogator to read radio frequency identification tags. The ambient noise is measured after the radio frequency identification interrogator has transmitted a signal. The measured level of ambient noise is then used to dynamically adjust a threshold value used to predict collisions on the channel.
