Both themes were highlighted during the 2019 World Radiocommunication Conference (WRC-19) promoted by the International Telecommunication Union (ITU), a United Nations body and could have an impact on broadening the bandwidth available for high speed mobile phone communications. but also in connection with other equipment from the Internet of Things.
For mobile services additional frequency bands have been identified, globally harmonized for the implementation of 5G, namely the 24.25-27.5 GHz bands; 37-43,5 GHz and 66-71 GHz, as Anacom indicates in a statement. However, there are some conditions associated with the use of this additional spectrum, which goes beyond the power limits for the protection of the satellite (passive) Earth Exploration service in the bands below 24.25-27.5 GHz and at 36-37 GHz.
The same conference also identified other regional mobile bands that do not cover the whole of Europe and which, together with the bands already identified for 5G, could contribute to "the development of scenarios requiring bandwidths". higher communications, massive machine-type communications and lower latency and higher reliability communications, "the same source indicates.
In the area of satellites, WRC-19 has decided to approve "a broad set of technical and regulatory provisions to promote the development and implementation of new low-frequency orbit satellite systems shared with geostationary satellites", which will increase supply. from the space component under the concept of “network of networks” to more efficient broadband applications such as remote sensors for space research, meteorology, astronomy, technology demonstration and scientific experiments.
"It was intended to lay the groundwork for the new satellite systems to be mega constellations, consisting of hundreds to thousands of low-orbiting space objects that could become a solution for global telecommunications and other applications ", explains Anacom.
Satellites can create a complementary offering to the terrestrial component, either as backhauling, in areas where terrestrial coverage is adequately secured, or in locations where satellites can be used in remote or oceanic terrestrial areas.
The next World Radiocommunication Conference will be held in 2023 and the approved agenda will include the debate on additional spectrum for mobile communications between 3,300 MHz and 10,5 GHz; and reviewing spectrum use and spectrum needs of existing services in the 470-960 MHz frequency range in Region 1; among other topics.
