 Global communication depends on a shared radio frequency spectrum and well-managed satellite orbits. Global use of these resources is governed by an international treaty, the Radio Regulations. The International Telecommunication Union, ITU, is the custodian of the Radio Regulations. As the United Nations Specialised Agency for Information and Communication Technologies, ITU also provides innovative tools to help countries and industry navigate the radio regulations. ITU's Radio Regulations Navigation Tool spans the treaty and all associated publications. Developed by the ITU Radio Communication Bureau, the software gives you one stop access to the ITU Radio Regulations, the rules of procedure which guide practical implementation, ITUR recommendations or international technical standards for efficient spectrum use by all radio communication services, frequency allocation tables, relevant articles of the ITU Constitution and Convention. The navigation tool works with all widely used operating systems. The tool helps you navigate over 15,000 references including articles, provisions and annexes. You can also easily access ITUR recommendations cited but not included in the radio regulations. The tool keeps your navigation history for easy reference and enables powerful searches across all four volumes of the radio regulations and quick identification of the rule of procedure applicable to a given provision. Consulting the ITU Radio Regulations has never been easier. Get your ITU Radio Regulations Navigation Tool license now. Contact sales at itu.int to place your order.
