Abstract:
1. A wireless communication network, comprising: a base node, a field node, a reference node and a host; the base node communicatively coupled to the host; the base, field and reference nodes each comprising a wireless conversion unit and a wireless transceiver; the wireless transceivers of the base, the field and the reference nodes effecting wireless communications amongst the base, field and reference nodes; the field node comprising at least one field device providing process control data; the reference node comprising a geographical positioning apparatus to determine geographical position of the reference node; an RF noise measurement apparatus located on at least one of the base, field and reference nodes, wherein the RF noise measurement apparatus is to determine RF ambient noise levels at the RF noise measurement apparatus over a predetermined time period; and a power settings apparatus located on at least one of the base and reference nodes, wherein the power setting apparatus is to determine the geographic position of each of the base and field nodes relative to the reference node, and determine RF power settings of the wireless transceivers of at least one of the base, the field and the reference nodes using the geographic position of the at least one of the base and field nodes and using the RF ambient noise levels determined by the RF noise measurement apparatus.
