On October 28, 2019, the International Telecommunications Union’s (ITU) World Radiocommunication Conference (WRC-19) will convene in Geneva for four weeks of multinational deliberations on possible updates to the ITU Radio Regulations (RR). RR is a document setting out the basic international rules of spectrum use and is a treaty between the 193 member nations of the ITU. Such conferences are held every four or five years. This article is the second in a series reviewing the impact of issues on the agenda and their possible impact on radiocommunications spectrum use. The point here is to both inform readers about issues under consideration and to encourage them to get involved in their national process for inputs to the conference.
