name: EESS
full_form: Earth Exploration Satellite Service
context: The International Telecommunication Union World Radiocommunication Conference 2019 (WRC-19) created an internationally recognized 24.25 to 27.5 GHz band aiming at primary mobile allocation for licensed/IMT networks deployments. In addition to it, the limits of unwanted emission power from active service stations in that band were specified to protect 23.6-24 GHz EESS (passive) band. A summary of the WRC-19 agreement related to EESS unwanted emission limits is given below [13]: For 5G Base stations: - -33 dBW in any 200 MHz of the EESS (passive) band for IMT/5G base stations brought into use before 1st September 2027. - -39 dBW in any 200 MHz of the EESS (passive) band for IMT/5G base stations brought into use after 1st September 2027. - The -39 dBW/200 MHz limit will not apply to 5G base stations which have been brought into use prior to this date. - For those base stations, the limit of -33 dBW/200 MHz will continue to indefinitely apply after this date. For 5G User equipment: - -29
description: The Earth Exploration Satellite Service (EESS) involves using satellites for earth exploration tasks like remote sensing and data collection. Within 3GPP specifications, EESS focuses on safeguarding this service from interference caused by IMT/5G base stations and user equipment.
explanation: The text explicitly states that EESS is a type of satellite service requiring protection from unwanted emissions. This emphasis on its role as a service needing specific safeguards classifies it as a Service.
