It includes information on various satellite delivery and broadcasting services, such as BO, BR, BS, and BT. The document details series titles and corresponding services. Additionally, it presents data related to power density in dBW/100MHz across different frequencies in GHz, with a focus on EESS protection. Furthermore, it provides comparative study results from Annexes A, A1, B, and C, detailing link densities per km² for urban and rural areas, and link percentages for high elevation angles. These studies appear to assess the performance and protection requirements of Earth Exploration Satellite Service (EESS) within the fixed service context.","| Series of ITU-R Reports\u003Cbr>(Also available online at [http://www.itu.int/publ/R-REP/en](http://www.itu.int/publ/R-REP/en))\u003Cbr>Series Title\u003Cbr>BO Satellite delivery\u003Cbr>BR Recording for production, archival and play-out; film for television\u003Cbr>BS Broadcasting service (sound)\u003Cbr>BT Broadcasting service (television)\u003Cbr>\u003Cbr>F Fixed service |  |\n| --- | --- |\n| M\u003Cbr>P\u003Cbr>RA\u003Cbr>RS\u003Cbr>S\u003Cbr>SA\u003Cbr>SF\u003Cbr>SM | Mobile, radiodetermination, amateur and related satellite services\u003Cbr>Radiowave propagation Radio astronomy Remote sensing systems Fixed-satellite service\u003Cbr>Space applications and meteorology\u003Cbr>Frequency sharing and coordination between fixed-satellite and fixed service systems Spectrum management |\n\n| FS Power density ( dBW/100MHz) | -30\u003Cbr>-35 -40 -45 -50 -55 -60 -65 -70 -75 -80\u003Cbr>|\n| --- | --- |\n| 86 86.5 87 87.5 88 88.5 89 89.5 90 90.5 91 91.5 92\u003Cbr>Frequency (GHz)\u003Cbr> Required reference unwanted emission limit for EESS protection  Equivalent unwanted emission mask for EESS protection |  |\n\n\n|  | Study 1\u003Cbr>(Annex A) | Study 1\u003Cbr>(Annex A1) | Study 2\u003Cbr>(Annex B) | Study 3\u003Cbr>(Annex C) |\n| --- | --- | --- | --- | --- |\n| Urban (hot spots) | 0.5 links/km² | 0.1 to 0.5\u003Cbr>links/km² | 0.1 to 0.19\u003Cbr>links/km² | 0.1464 to\u003Cbr>0.2382 links/km² 1) |\n| Rural\u003Cbr>(outside hot spots) | 0.06 links/km² | 0.01 to 0.06\u003Cbr>links/km² | 0.01 to 0.02\u003Cbr>links/km² |  |\n\n|  | Study 1\u003Cbr>(Annex A) | Study 1\u003Cbr>(Annex A1) | Study 2\u003Cbr>(Annex B) | Study 3\u003Cbr>(Annex C) |\n| --- | --- | --- | --- | --- |\n| High elevation links | 0.39% of links with elevation higher than 20° | 0.1 to 0.5 % of links with elevation between 30° and 45° | ± 30° (normally distributed) | Less than 2% of links with elevation between 20° and 65° |","cbCairpwHYi2EBx8","https://ap.wps.com/l/cbCairpwHYi2EBx8","pdf",4430344,66,"English","en",105,"# Series of ITU-R Reports\n## BO Satellite delivery\n## BR Recording for production, archival and play-out; film for television\n## BS Broadcasting service (sound)\n## BT Broadcasting service (television)\n## F Fixed service\n## M Mobile, radiodetermination, amateur and related satellite services\n## P Radiowave propagation Radio astronomy Remote sensing systems Fixed-satellite service\n## RA Space applications and meteorology\n## RS Frequency sharing and coordination between fixed-satellite and fixed service systems Spectrum management\n## S Spectrum management\n## SA Spectrum management\n## SF Spectrum management","[{\"question\":\"What is the primary focus of the F series in ITU-R Reports?\",\"answer\":\"The F series in ITU-R Reports focuses on the Fixed Service, which involves the exchange of information between fixed points, often utilizing satellite or terrestrial means.\"},{\"question\":\"What does EESS stand for and what is its relevance in this document?\",\"answer\":\"EESS stands for Earth Exploration Satellite Service.
