An example of high level consultancy is the work done on the GTAG Project. GTAG was an initiative to develop a global standard for UHF RFID. Nick Long was the RF expert on the three man team working for the Uniform Code Council that first drafted the technical standard for GTAG.
 
Prior to GTAG, each manufacturer offered his own proprietary standard, and protocols and frequencies varied around the world. GTAG was the global standard that brought them all together. It led to the ISO 18000 standard and the EPG Global specifaction which have enabled UHF RFID to take off worldwide.
 
The Uniform Code Council formed the EPCGlobal organisation. Nick remains active as an expert in the underlying technology making RFID work.
