In September 2008, Emerson became the first process automation supplier to begin production shipments for its WirelessHART enabled products.
During the summer of 2009 NAMUR, an international user association in the chemical and pharmaceutical processing industries, conducted a field test of WirelessHART to verify alignment with the NAMUR requirements for wireless automation in process applications.
In April 2010, WirelessHart was approved by the International Electrotechnical Commission
(IEC) unanimously, making it first wireless international standard as IEC 62591.
Description
The protocol utilizes a time synchronized, self-organizing, and self-healing mesh architecture. The protocol supports operation in the 2.4 GHz ISM bandISM band
The industrial, scientific and medical radio bands are radio bands reserved internationally for the use of radio frequency energy for industrial, scientific and medical purposes other than communications....
