Abstract
A wireless communication system for use in a process control environment includes a reference node adapted to determine geographic positions of at least some of the reference node, a base node, and a field node and determine RF power settings of transceivers attached to the reference node, the base node, and the field node based on the position of determined geographic positions. Additionally, the reference node is adapted to determine RF noise level at a plurality of locations within the process control environment at a plurality of times and to adjust the RF power settings based on the determined RF noise levels. The reference node may be implemented on a hand-held device.
