Introduction Growing demand for satellite services has resulted in hundreds of satellites worth tens of billions of dollars already deployed, and continuing to be deployed, in Ka-band, including the 28 GHz (27.5-29.5 GHz) band for Earth-to-space transmission. It is critical to preserve and expand the satellite systems in the 28 GHz band and consider other mmWave bands for 5G terrestrial mobile services, such as 26 GHz, to allow for the growth of both 5G mobile networks and satellite services.1 This is especially clear when considering the demand for satellite services that already exists in the 28 GHz band, the critical role of satellites in the 5G ecosystem, the adverse impact of repurposing satellite spectrum, and the low likelihood of global harmonization of the 28 GHz band for 5G terrestrial mobile services. 2. Satellite operations in the 28 GHz band Over the past two decades, the satellite sector has launched a substantial number of Ka-band satellite systems, and has continued to develop even more efficient and powerful space and ground segments. Today, the 28 GHz frequency portion of the Ka-band plays a key role in current satellite operations with upwards of 130 geostationary (GSO) and non-geostationary (NGSO) satellite systems, including High Throughput Satellite (HTS) systems, using the band globally (see Annex 1) and providing valuable service to end users globally. The number of satellite systems will continue to grow in order to accommodate increasing customer demand for existing services as well as new market opportunities that are currently developing. Latest reports available from the International Telecommunication Union (ITU) show that over 1500 satellite network filings have been submitted in the Ka-band demonstrating the importance of this band for continued satellite uses. The same developments are taking place in the Americas region, where satellite operators have been deploying or are planning to deploy GSO and NGSO, HTS systems in both low Earth orbit (LEO) and medium Earth orbit (MEO) in the 28 GHz band. Governments and consumers in the region are increasingly relying on the 28 GHz band for a wide range of services that are most efficiently delivered by satellites, and that sometimes can only be delivered over satellites. Brazil, the largest country in both South America and Latin America, is a good example with the SGDC satellite providing government- mandated broadband services as well as commercial services. In the border state of Amazonas, a remote area covering a population of 500,000 currently accesses broadband connectivity using MEO satellite capacity. Table 1 shows a non-exhaustive list of operational and planned GSO Ka-band satellites in Brazil.

Table 1: An Example: Existing and new Ka-band satellites in Brazil It is imperative that the global, regional and national regulatory landscapes support continued operation and growth of satellite services in the 28 GHz band without constraints in order to protect the substantial, long-term investments of satellite operators. The investments in the (non-exhaustive) list of operational and planned HTS systems in Annex 1, along with associated ground infrastructure, amount to billions of USD. Sudden changes in the regulatory environment would jeopardize these investments and reduce commercial viability of existing satellite services. Indeed, long-term regulatory certainty is required to maintain thriving satellite operations in the 28 GHz band as the design and deployment cycles for satellites approach or exceed 20 years. This includes a design period that ends as early as 30 months prior to launch for a typical geostationary satellite with a design lifetime of 15 years, and which often has an actual service lifetime that is a few years longer. 3. Use of 28 GHz band by satellite earth stations 3.1 Ubiquitously deployed earth stations There has been significant growth in satellite services that involve the deployment of a large number of small, transmit-receive user terminals. This growth is fueled by consumer demand for high quality broadband connectivity regardless of their location, a demand that satellites are often uniquely positioned to address. The technological developments of space and ground segments are further enabling the ability to service this demand by providing higher data rates at reduced cost. Much of this growth in satellite services is expected to be met by the deployment of small user terminals, particularly in the 28 GHz band. In line with this trend, some satellite operators are planning to move their gateway links into higher frequency bands in order to accommodate more user terminals in the 28 GHz band. This illustrates the demand for a large quantity of spectrum in the 28 GHz band for user terminals. It is essential that the operation of FSS user terminals are not constrained by the addition of any other services in the band. Because of the importance of the 28 GHz band for satellite systems, the entire 27.5-29.5 GHz band currently is available for broadly deployed FSS earth stations in numerous Latin American countries. For example, in Mexico, the entire 27.5-29.5 GHz band is both exclusively allocated for the FSS and licensed for ubiquitously deployed user terminals on a blanket-license basis. In Brazil, the 27.5-29.5 GHz band is available for “block” (or blanket) licensing of FSS user terminals operating on a primary basis. In fact, in 2017, ANATEL limited the use of the 27.9-28.4 GHz band segment to the FSS. Blanket licensing of CCPII-2018-32-4775r1_i 18.12.18 2 FSS user terminals also is possible throughout the 27.5-29.5 GHz band in Uruguay, among other countries in Latin America. The FCC in the U.S. has made the bands 28.35-29.1 GHz and 29.25-29.5 GHz available only for the FSS, including ubiquitously deployed satellite user terminals. The FCC also has committed to consider allowing ubiquitously deployed satellite user terminals at 27.5-28.35 GHz in light of “the evolving nature of technology and deployment.”2 Millions of satellite broadband user terminals already have been deployed under these types of rules. As demonstrated above, individual licensing is not feasible for ubiquitously deployed earth stations because of the licensing process required and the siting restrictions that would result. As other countries have found, user terminals are appropriately licensed on a blanket licensing basis. Requiring individual licensing for user terminals would be overly burdensome to regulators, operators and users, resulting in significant delay in end users receiving broadband services 3.1.1 Earth Stations in Motion Agenda Item (AI) 1.5 of the 2019 ITU World Radiocommunications Conference (WRC-19) will consider the use of the frequency bands 17.7–19.7 GHz (space-to-Earth) and 27.5–29.5 GHz (Earth-to-space) for Earth Stations in Motion (ESIMs) communicating with geostationary space stations in the FSS. Aircraft, ships and land vehicles need consistent connectivity when they travel long distances, and also operate in areas outside terrestrial coverage. There is soaring demand by passengers to be connected while travelling.
