GENEVA, Oct. 28 (Xinhua) -- The World Radiocommunication Conference (WRC-19), which opened in Sharm El-Sheikh, Egypt on Monday, focuses on the management of the radio frequency spectrum and its use by the rapidly evolving terrestrial and space-based communication technologies, the International Telecommunication Union (ITU) said on Monday.

The conference, held every three to four years, is scheduled to review and revise the ITU Radio Regulations, the international treaty governing the use of radio frequency spectrum, a scarce resource, and satellite orbits.

Participants will discuss the cutting edge technological innovations that are set to play a pivotal role in tomorrow's digital economy and the future development of services, systems and technologies, according to ITU Secretary General Zhao Houlin.

One of the major fields to be covered at the conference is 5G services. In that context, mobile technology innovations will be discussed, additional frequency bands for the future development of international mobile telecommunications will be considered, and the rollout of IMT-2020 networks, also known as 5G networks, is expected to be finalized.

The conference will consider additional frequencies for Earth Stations in Motion (ESIM) communicating from aircraft, maritime vessels and land vehicles with satellites on geostationary orbit (GSO) to include the 18 gigahertz (GHz) and 28 GHz bands. This reflects the advances in technology and the growing demand for satellite-based connectivity systems.

The more than 30 items on the conference's agenda also include proposals to enhance the international regulatory framework to improve satellite broadband connectivity from new non-geostationary satellite systems, and to provide effective communication for portable and mobile computer-based equipment over wireless access systems, including wifi.

Decisions taken at the conference will "not only allow for new technologies and services to be deployed without interfering with existing ones, but also extend the benefits of technological advancement to all the world's citizens, bringing potential benefits to our society, the global economy and the environment," said Mario Maniewicz, director of the ITU Radiocommunication Bureau.

This year's conference is expected to bring together over 3,500 participants from the ITU's 193 member states, 267 observers from its 900 private sector members, as well as representatives of international organizations. Enditem
