TOP INTERESTING FACTS ABOUT 5G SATELLITES

THE ROLE OF SATELLITES FOR 5G AND BEYOND

· Satellite systems are expected to play an important role in 5G and beyond wireless network systems. The vision of 5G is driven by the increased data rates and connection density, significantly reduced network latency, and optimized network efficiency. However, there are several use cases where standard terrestrial coverage is either not present or possible, making satellite systems uniquely positioned to provide a solution to bridge this gap. Satellite communication will play a significant role in 5G and beyond as a complementary solution for ubiquitous coverage, broadcast/multicast provision, aeronautical & maritime communications, emergency/disaster recovery, and remote rural area coverage.
· Recent years have also seen several advances in satellite systems and networks, allowing better efficiency, reliability, increased data rates, and new applications. By 2020-2025 there will be more than 100 High Throughput Satellite (HTS) systems using Geostationary (GEO) orbits but also mega-constellations of Low Earth Orbit (LEO) satellites, delivering Terabit per second (Tbps) of capacity across the world.

· The new systems will encompass a multi-layer aerial component with LEOs, HAPs, UAVs, and drones. New cost-effective system architectures such as CubeSat and Starlink systems should be considered. Some standards organizations like 3GPP (Release 16 and now Release 17) have worked on these Non-Terrestrial Networks (NTN). 5G and beyond 5G satellite systems have to meet the KPIs in peak data rates, spectral efficiency, connection density, e2e latency, delay jitter, and mobility.

Indian start-up to launch 35+ satellite constellation for 5G

· BENGALURU: Vestaspace Technology, an Indian nano, cube, and small satellites manufacturing company and space service provider on Tuesday, announced its plans to launch a constellation of more than 35 satellites to build 5G speed network connections and IoT functionalities across all the industries.
· “With an AI-Powered novel communication architecture, we are set to release a beta version of the next-generation satellite constellations this September 2020 and the launch of a fully operational constellation of satellites in early 2021 into Low-Earth-Orbit or Geosynchronous Equatorial Orbit,” the firm said in a release.
· The company plans to replace traditional fiber networks with all the satellite constellations and provide high-speed 5G network connections pan-India with its unmanned software data

Processing along with successful launches of orbiting satellites and understanding next-generation satellites data needs. To provide accessible solutions, the company says it has come up with a concept of services where a commoner can uplink and downlink the data while browsing the internet.

“The solutions will prevent any fraud and illegitimate operations while uploading or downloading data from the satellites, there are 10 layers of security firewall put up that does data assessment and possibly takes immediate actions if any false data is found,” the firm said.

Initially, Vestaspace claims it accomplished good results at the proprietary system by pointing out the accurate antenna, tracking, seamless beam, and satellite handovers.

“The outcome reflected in a live-streamed video of 1080p (Full HD) with less than 34 milliseconds latency with the speed of more than 400 Mbps,” the firm said.

· Arun Kumar Sure ban, Founder & CEO, Vestaspace Technology, said that their advanced AI-technology-based unmanned satellites data would bring in-depth solutions to the telecom industry and the common people.

“...to solve the complex system and to provide 5G internet network solutions to the urban, rural and unserved regions, we have positioned eight ground stations and 31,000 data receptors all over India. This is made possible with the help of accurate positioning, and telemetry related activities,” Sure ban said

Recently, the company has secured $10 million funding from US-based Next Capital LLC, an American investment and advisory firm, to expand the reach of Vestaspace's innovative solutions across India and the world.

The company has also been working with ISRO, NASA, and other leading space agencies on various strategic projects which will help Vestaspace to expand globally.

AMERICA’S 5G FUTURE SPECTRUM (5G SPEEDOMETER)

The FCC is taking action to make additional spectrum available for 5G services.

· HIGH-BAND: The FCC has made auctioning high-band spectrum a priority. The FCC concluded its first 5G spectrum auctions in the 28 GHz band, the 24 GHz band, and the upper 37 GHz, 39 GHz, and 47 GHz, bands. With these auctions, the FCC is releasing almost 5 gigahertz of 5G spectrum into the market—more than all other flexible use bands combined. The FCC is also working to free up 2.75 gigahertz of the 5G spectrum in the 26 and 42 GHz bands. It has initiated a more efficient use of additional millimeter-band spectrum in the 70/80/90 GHz bands.
· MID-BAND: mid-band spectrum has become a target for 5G buildout given its balanced coverage and capacity characteristics. With our work on the 2.5 GHz, 3.5 GHz, and 3.7-4.2 GHz bands, we will make more than 600 megahertz available for 5G deployments.

Low-band: The FCC is acting to improve the use of low-band spectrum (useful for wider coverage) for 5G services, with targeted changes to the 600 MHz, 800 MHz, and 900 MHz bands.

Unlicensed: Recognizing that unlicensed spectrum will be important for 5G, the agency creates new opportunities for the next generation of Wi-Fi in the 5.9 GHz, 6 GHz, and above 95 GHz band.

MODERNIZING OUTDATED REGULATIONS:

· The FCC is modernizing outdated regulations to promote the wired backbone of 5G networks and digital opportunity for all Americans.

· 5G FUND FOR RURAL AMERICA: The Commission established the 5G Fund for Rural America in October 2020 to make up to $9 billion in Universal Service Fund support available to carriers to deploy advanced 5G mobile wireless services in rural America (including up to $680 million for deployment on Tribal lands). The Fund also sets aside at least $1 billion specifically for deployments facilitating precision agriculture needs.

One-Touch Make-Ready: The FCC has updated its rules governing the attachment of new network equipment to utility poles to reduce cost and speed up the 5G backhaul deployment process.

· SPEEDING THE IP TRANSITION: The FCC revised its rules to make it easier for companies to invest in next-generation networks and services instead of the fading networks of the past.

Supply Chain Integrity: The FCC adopted a rule banning the use of taxpayer dollars (in the USF programs) from being used to purchase equipment or services from companies that pose a national security threat to the integrity of American communications networks or the communications supply chain.

JAPAN'S 5G NETWORKS :

· Japan is an attractive market for U.S. suppliers of 5G equipment and related services. Over the next five years, the four Japanese mobile carriers will spend more than $14 billion combined in capital expenditures to build their 5G networks. This includes investments in base stations, servers, and fiber optics. In 2019, U.S. suppliers exported more than $720 million in telecom equipment (HS 8517.62) to Japan. The establishment of 5G is a high priority for the Japanese government.
· The Ministry of Internal Affairs and Communications (MIC) is the lead agency on 5G. Four companies submitted plans to MIC for the development of 5G networks. All four plans were approved based on certain conditions, including

: 1) focusing on the needs of both urban and rural areas; 2) maintaining appropriate and sufficient optical fibers to provide 5G service; and 3) taking adequate cybersecurity measures, including measures against supply chain risks. Three of the four companies — NTT DOCOMO, KDDI au, and Softbank — are established carriers, while the fourth, Rakeem Mobile, is relatively new. All four were assigned 5G spectrum by the Japanese government on April 10, 2019. According to Fitch Research, 4G subscriptions in Japan will start declining in 2022, with 5G becoming the dominant technology by 2026. Fitch forecasts that by 2029, there will be roughly 45 million 4G subscriptions and more than 151 million 5G subscriptions in Japan.

SOUTH KOREAN 5G NETWORK :

· Thales Alania Space will be taking part in a 5G demonstration in Asia, the company announced Thursday. It will partner with South Korean operator KT SAT, a subsidiary of one of the world’s first 5G commercial service providers, Korea Telecom, to lead a 5G demonstration using the Geostationary (GEO) Koreasat 5A telecommunication satellite to provide a 5G network to remote areas. KT SAT will use

5G backhauling as a key element of satellite integration in the 5G world. This experiment consists of backhauling the connection between a 5G core network and a 5G gNB through KT SAT Koreasat-5A. In this case, the satellite is not only a complement to terrestrial 5G network but a fully integrated part of it by receiving the 5G network from Earth and then returning it to remote areas where traditional backhauling technologies (wired, fiber, radio beams) are not suitable for technical and/or economic reasons. In November last year, KT SAT unveiled a router for hybrid satellite-terrestrial 5G transmission. The hybrid router, demonstrated online, was developed with the KT Institute of Convergence Technology, further expanding the role of satellites in 5G services.
· “This satellite-based 5G backhaul experiment using Koreasat has opened possibilities for 5G communications without geographical divisions caused by mountains and oceans. Based on this technology, KT SAT will expand its global outreach, particularly in Southeast Asia where terrestrial network construction faces difficulties,” KT SAT CEO Song Kyung-Min said in a statement.
