To power immersive mobile experiences in 5G, Samsung has introduced advanced 5G solutions that include new baseband units and radios. Among these 5G radios, Massive Multi-Input Multi-Output (MIMO) radios are one of the most attractive options for mobile operators looking to deploy or enhance their 5G networks. The massive MIMO radio is a breakthrough solution that is equipped with a lot of antennas for better coverage and more capacity than a radio. As 5G networks continue to expand around the world using mid-band spectrum, 5G Massive MIMO radios with hundreds of antennas are commonly deployed in the market to help handle the growth in mobile data traffic.

To develop these powerful 5G Massive MIMO radios, numerous tests must be conducted to inspect the products for performance and reliability. One of the tests is conducted at a special facility called an anechoic chamber. Samsung Electronics has several anechoic chambers that are used to analyze and test the antenna performance of its radios. Recently, the company opened a large anechoic chamber at its Digital City campus in Suwon, Korea in order to enhance its ability to introduce more advanced and compelling 5G solutions to its customers.

Testing in Anechoic Chambers

The term “anechoic” comes from “an-echoic”, meaning non-echoing or non-reflective in Greek. As its name suggests, this room can emulate a non-reflective environment by using special walls and ceiling and floor designs to completely absorb all reflected electromagnetic waves. This is extremely important since even a small electromagnetic wave can disrupt an accurate antenna measurement. The interior walls are built with a number of absorbers that have a pyramid shape and help to minimize interference in the shielded room. This concept is very similar to how a stealth aircraft evades radar detection by absorbing and scattering radar signals.

The chamber’s interior is also equipped with a parabolic reflector. This reflector is used to collect radio waves from a generator and re-project the waves to the 5G radios placed inside the chamber. By collecting and re-projecting the waves at different angles, the parabolic reflector can simulate long distances, making it seem as though the 5G radio were transmitting radio waves to a mobile device from a far-off location. While the size of the chamber is relative to the simulated distance, Samsung’s chambers can simulate a distance of as much as hundreds of kilometers, creating what is called a “far field condition”. To measure the accuracy of radio performance, the size of the chamber is critical.

The newly added non-reflective chamber in Samsung’s Digital City is the size of a basketball court. Beneath the reflector, the engineer looks as small as an insect!

Samsung’s anechoic chambers are also able to cover a wide range of spectrum across low, mid and high-bands. This is especially useful in evaluating 5G radio performance since 5G spans various spectrum bands. Specifically, Samsung’s facilities have the ability to test mmWave antennas, which power high-capacity 5G mobile services. The mmWave spectrum is not used in 4G technology but is crucial to supporting immersive 5G use cases due to its wide-bandwidth.

By enabling tests to be conducted using a range of spectrum, the data sets collected in this way will help Samsung’s engineers verify and analyze a very high number of radio patterns. Based on the findings, engineers are able to refine and improve 5G radio performance to deliver best-in-class solutions for mobile services.

“We are extending our capabilities by developing powerful 5G solutions with the newly added anechoic chamber,” said Seunghwan Yoon, Vice President and Head of the RF Lab at Samsung Electronics’ Networks Business. “With vigorous quality control and verification processes, we look forward to bringing the full benefits of cutting-edge 5G solutions to more users for immersive mobile experiences.”

Better, More Powerful and Reliable 5G Solutions

The establishment of anechoic chambers is part of Samsung’s ongoing efforts to provide superior, reliable 5G solutions that deliver ultra-fast connectivity to users. These chambers help Samsung develop innovative antenna systems tailored to advanced 5G solutions in a wide array of spectrum bands. By leveraging a range of tools and facilities like anechoic chambers, Samsung looks forward to delivering leading-edge 5G solutions that offer consumers and enterprises around the globe new and immersive mobile experiences.

In partnership with Samsung Networks, Jio has built the world’s largest green-field and all IP based 4G LTE network, which supports over 340 million LTE subscribers as of August 2019.

At the event, the two companies present new business opportunities using 5G NSA mode, with advanced 4G LTE and 5G technology used in combination as a dual-connected mode network. These will demonstrate how innovations from the latest technology can benefit consumers, enterprises and the society.

“The unprecedented data growth and the mobile internet adoption and revolution that Jio brought to India has fundamentally changed the life of every Indian,” said Mathew Oommen, President of Reliance Jio Infocomm. “We as Jio, working closely with key partners like Samsung will ensure that we continue to help India leapfrog traditional technologies by advancing the existing 4G all-IP infrastructure and leverage the end-to-end fiber, 5G, and IoT ecosystems towards a digital infrastructure platform. This digital platform will deliver on the aspirations of all Indians, our businesses, and the emerging digital society that is fundamental to accelerating the digital economy and ensuring digital freedom for India.”

“Having superior LTE networks is a key asset for operators in moving towards the 5G era, and Jio has reached that compelling competency,” said Paul Kyungwhoon Cheun, Executive Vice President and Head of Networks Business at Samsung Electronics. “Samsung has been working in close cooperation with Jio to bring a digital transformation including the transition to 4G throughout India for over seven years. Samsung and Jio will continue to join forces in bringing next generation innovation across the country, harnessing the full 5G potential in driving further growth of a ‘Digital India’.”

5G Use Cases for Digital India

Samsung and Jio jointly highlight immersive and live applications of 5G that will demonstrate the value that 5G has to offer in India. The trial will feature solutions from Samsung Networks’ 5G product portfolio, including its 3.5GHz solution for 5G Massive MIMO Unit (MMU), its 28GHz Access Unit (AU) and CPE device, its virtualized radio access (vRAN) and core, and 5G mobile devices. Demonstrations will include:

• Virtual Classroom allows attendees to watch 360-degree virtual lecture taken from a classroom in Jio’s Reliance Corporate Park (RCP) in Mumbai.

• Massive Full High-Definition (HD) Content Streaming shows FHD video streaming on multiple smartphones (Galaxy S10 5G) simultaneously and 4K video streaming using multiple 5G tablets, which will showcase the unparalleled entertainment experience powered by 5G.

4G Use Cases for Public Safety Communications

Jio and Samsung will demonstrate a live “public safety network over LTE” featuring Mission-Critical-Push-To-X (MCPTX) communication. Conceptualized as “OneNet”, a potential India’s Emergency Communication Network, this will enable first responders to connect with each other using a broadband network in a controlled and “geo-fenced” manner.

Public Safety LTE (PS-LTE) using MCPTX goes beyond what was possible through legacy technologies in which they were limited to providing voice-oriented communications. By highlighting the use of LTE for real-time streaming of videos and high-definition images of scenes during emergencies, it enables multi-lateral communications to be connected at once to transfer video, images and voice simultaneously using multicast technology. As allowing the first responders and control towers to engage in highly effective communications, PS-LTE is enabled to make better decisions during time-critical situations.

As Jio has already built the largest and most advanced LTE network nationwide reaching every corner of Pan-India, MCPTX for PS-LTE is among the most effective ways to maximize the current LTE network to serve public safety for over 1.3 billion people.

Samsung is one of the first companies to launch a 5G commercial network in Korea and the U.S. in the first half of 2019 using its end-to-end 5G solutions ranging from chipsets, radios, core network solutions and smartphones for both mid-band and mmWave.

Korean operators have been transmitting 5G signals in Seoul and metropolitan areas since December 1, 2018 using 5G base station radios and 5G core solutions from Samsung’s Networks Business unit. To further expand the 5G network, Samsung has supplied 5G core solutions and more than 53,000 5G radio base stations to Korea’s three operators.

“Korea is one of the first markets in the world in which the 5G experience is opening up for consumers, and we’re thrilled to play a key role in the nationwide rollout of 5G with our unparalleled 5G network solutions,” said Paul Kyungwhoon Cheun, Executive Vice President and Head of Networks Business at Samsung Electronics. “As a longstanding innovator in the 5G space and one of the few vendors offering a full end-to-end 5G solution, Samsung is at the forefront of pushing the limits of 5G and beyond.”

Korean operators rolled out their commercial 5G networks using Samsung’s 5G Massive-MIMO Unit (MMU) radio base station in the 3.5GHz spectrum. A key characteristic of Samsung MMUs deployed in Korea is that they are among the smallest and lightest in the industry, ensuring they can be easily installed in existing operators’ cellular sites requiring minimal changes. This ability to re-use existing site has been key to enabling the Korean operators to deploy 5G network consisting of tens of thousands of radios within just few months since the Dec 1^st launch.

The virtualized 5G core solutions, provided to all three Korean operators for their 5G commercial launch, support both legacy 4G networks and next generation 5G services in Non-Standalone (NSA) mode. They can also migrate to Standalone (SA) mode through a simple software upgrade in the future. Samsung’s solution implements many of the key technologies of 5G networks, such as Control and User Plane Separation (CUPS), which are essential for network operators to scale their networks and support the new services enabled by 5G technology.

“Korea has long been regarded a leader when it comes to mobile technology and service adoption, and it is a market that other operators and vendors follow closely, said Daryl Schoolar, Practice Leader for Service Provider Technologies at Ovum. Samsung’s significant role in helping all three Korean mobile operators roll out their commercial 5G networks gives the vendor significant credibility as it looks to expand its 5G network solutions into other markets around the globe.”
