In order to use MU-MIMO, the system needs to find two or more users that need to transmit or receive data at the very same time. Active and Passive Antennas. Such features are already used with conventional systems in today's LTE networks. There is a trade-off between sub-array gain and beam width – the larger the sub-array, the higher the gain and the narrower the beam width, as illustrated in section B of Figure 3. Recent technology developments have made advanced antenna systems (AAS) a viable option for large scale deployments in existing 4G and future 5G mobile networks. AAS is a powerful option for MNOs that want to improve coverage, capacity and user performance using existing network sites. Together with the high site density, this leads to a situation where the signals from interfering base stations are strong, and severe interference problems may occur. We continue to work and innovate to bring the best end-user experience to our 5G subscribers.”, “The acquisition of KMC is a key component in enhancing our end-to-end portfolio. A good trade-off between complexity and performance is an AAS with 8 to 16 radio chains. Working with Ericsson and deploying the Hybrid AIR, we are now delivering wide mid-band capacity, while re-using established sites and minimizing additional footprint, with the Hybrid AIR. As the tech firm that created the mobile world, and with more than 54,000 patents to our name, we’ve made it our business to make a mark. As with SU-MIMO, the total DL power is shared between the different layers, and therefore the power (and thus SINR) for each user is reduced as the number of simultaneous MU-MIMO users increases. Figure 4: Suitable AAS configurations, schematic MU-MIMO and SU-MIMO usage ranges, and typical capacity gains in different deployment scenarios. The potential diminishes when the mutual interference between streams increases. This is due to the bursty (chatty) nature of data transmission to most users. There is generally a mix of building types, which creates multipath propagation between the AAS and the UE. Due to larger ISDs and decreased vertical spread of users (lower buildings), the vertical coverage range can be decreased compared to dense urban high-rise; hence, larger vertical sub-arrays can be used and there is less gain from vertical beamforming. We have chosen three typical use cases that illustrate different aspects of AAS deployment: rural/suburban, urban low-rise and dense urban high-rise. Single-user MIMO (SU-MIMO) is the ability to transmit one or multiple data streams, called layers, from one transmitting array to a single user. AIR 4488 Triple-band antenna, 4T/4R, 3 bands, low-band and mid-band, 7 frequency bands AIR4488 3. For TDD, the same frequency is used for both UL and DL transmission. For full channel estimation, signals should be sent from each UE antenna and across all frequencies. This 448-platform solution with frequencies from 698 MHz up to 3800 MHz received 20+1-ports and measures with 2m height and 448 mm width. When transmitting, beamforming is the ability to direct radio energy through the radio channel toward a specific receiver, as shown in the top left quadrant of Figure 1. The potential is large when the received signal quality is high and the streams do not interfere with each other. Steerability is achieved by individually controlling the amplitude and phase of smaller parts of the antenna array. AAS enables state-of-the-art beamforming and MIMO techniques that are powerful tools for improving end-user experience, capacity and coverage. Ericsson Massive MIMO Macro 5G layer antennas 1. Using larger sub-arrays for a given antenna area means that fewer radio chains are required. AIR 8828 FDD AIR8828. In multi-user MIMO (MU-MIMO), which is shown in the bottom right quadrant of Figure 1, the AAS simultaneously sends different layers in separate beams to different users using the same time and frequency resource, thereby increasing the network capacity. Along the walls at one of Ericsson's demos, the strip was embedded behind a … in engineering physics and a Ph.D. in electrical engineering, specializing in signal processing, from Uppsala University, Sweden. Since the AAS and the transport network must be dimensioned for the maximum number of layers, the MNO needs to consider how many layers are required in their networks. End-to-end solutions for the construction of 5G radio sites that are both future-proof and cost-effective for mobile networks that will operate profitably. Similarly, when receiving, beamforming is the ability to collect the signal energy from a specific transmitter. The strip contains printed circuit boards and tiny antennas able to pick up and send 5G data. Ericsson announces smaller 5G antennas News Wire Feed Light Reading 6/30/2020 Comment (0) STOCKHOLM – Communications service providers can now deploy mid-band 5G … Ericsson Massive MIMO 5G integrated passive antennas 1. Compared to conventional systems, this solution provides much greater adaptivity and steerability, in terms of adapting the antenna radiation patterns to rapidly time-varying traffic and multi-path radio propagation conditions. This is particularly important when introducing 5G on existing site grids. Ericsson Massive MIMO 5G integrated passive antennas 1. As a result, AAS significantly enhances network performance in both uplink and downlink. Ericsson Massive MIMO Macro 5G layer antennas 1. Today, the IP landscape related to antenna for 5G is still unsettled. The total antenna gain is the product of the array gain and the sub-array gain, as shown in section C of Figure 3. Radio 2238 Triple-band radio … An AAS radio consists of an antenna array closely integrated with the hardware and software required for transmission and reception of radio signals, and signal processing algorithms to support the execution of the AAS features. Ericsson’s Cool R&D Effort – 5G Antennas and Strips of Tape By Bevin Fletcher | March 5, 2019 On display at MWC 2019 Barcelona Ericsson shows R&D work for 5G antennas and printed circuit boards attached to strips of tape. BT said … Applying AAS features to an AAS radio results in significant performance gains because of the higher degrees of freedom provided by the larger number of radio chains, also referred to as Massive MIMO. The suitable channel knowledge scheme to use depends on UL coverage and UE capabilities. 2. The new site solution for Swisscom introduces 3.5GHz support using a 32TRx radio on existing sites. Ericsson Multi-band 5G radios 1. Desired AAS characteristics in the dense urban high-rise scenario include an antenna area large enough to ensure sufficient coverage (UL cell-edge data rate). in electronic engineering from Dublin City University, Ireland. The gain and beam width depend on the size of the sub-array and the properties of the individual antenna elements. The antenna system is one of the most crucial areas in a radio access network and a fundamental pillar in the Ericsson 5G strategy. The factory is targeted at producing 5G and advanced antenna radio systems for 5G deployments in the United States as that is where Ericsson is seeing a bulk of the initial market deployments. Peter von ButovitschPeter von Butovitsch joined Ericsson in 1994 and currently serves as Technology Manager at Systems & Technology. A good trade off between complexity and performance is an AAS with 16 to 32 radio chains. Bo Göransson | Wireless@KTH | 5G & the multi antenna advantage | 2016-10-06 | Page 28 Ericsson 5G Roadmap 1st 5 Gbps throughput –June 2014 1st Dual Connectivity LTE-5G 1st Multipoint Connectivity with distributed MIMO 5G Radio Prototype field trials in 2016 Ericsson 5G field trial gear achieves peak downlink throughput over 25 Gbps with MU-MIMO The size of the array gain, relative to the gain of one sub-array, depends on the number of sub-arrays – for example, two sub-arrays gives an array gain of 2 (i.e. This calls for small sub-arrays, which have a wide beam in the vertical direction. Horizontal beamforming is a very effective feature that provides large gains. The demonstration, tested on a live network, used an Ericsson 5G mmWave high power antenna-integrated radio, equipped with Ericsson software. An advanced antenna system (AAS) is a combination of an AAS radio and a set of AAS features. DL transmission, on the other hand, is typically more challenging than UL reception because channel knowledge needs to be available before transmission. 28 October BT has signed a deal to use Ericsson's 5G radio antennas, base stations and other equipment to upgrade its EE mobile network. This will include active and passive antennas that will work across T-Mobile’s whole spectrum portfolio, be it low-band for coverage or higher band for high speeds and low latency, backed by Massive MIMO. Leading Swiss service provider Swisscom are on their journey to swap legacy 2G to 4G equipment and deploy 5G capacity across 102 locations throughout the country. It fits all site types and traffic scenarios, even as networks grow in scale and complexity. Therefore, large vertical sub-arrays with small vertical coverage areas are appropriate. Ericsson (ERIC) Telefonaktiebolaget LM Ericsson (ERIC) is a Swedish telecommunication equipment … This is achieved by controlling the transmitted signals in a way that they cancel each other out at the interfered UEs. Ericsson leveraged on the latest Kathrein Mobile Communications (KMC) antenna technology, and designed the Hybrid AIR site solution. MU MIMO is also appropriate at high loads due to the multi-path propagation environment, good link qualities and UE pairing opportunities. He has held various positions at Ericsson Research and in RAN system design over the years, and from 1999 to 2014 he worked for Ericsson in Japan and China. without impairing the installation object's appearance or design, or people's line of sight. The test, set up on the TIM 5G network, was based on an Ericsson 5G mmWave high-power, antenna-integrated radio AIR 5322, installed at the mobile … As depicted in section A of Figure 4, the dense urban high-rise scenario is characterized by high-rise buildings, short inter-site-distances (ISDs) of 200 500m, large traffic volume and high subscriber density with significant user spread in the vertical dimension. Each stream was capable of transmitting/receiving at more than 350 Mbps. MIMO builds on the basic principle that when the received signal quality is high, it is better to receive multiple streams of data with reduced power per stream, than one stream with full power. Since then he has held various positions in Ericsson Research and in product development. This allows the AAS to adapt the number of layers and determine how to beamform them. Ericsson Technology Review, Designing for the future: the 5G NR physical layer, available at: Ericsson Technology Review, Evolving LTE to fit the 5G future, available at: Ericsson Technology Review, 5G radio access, available at: Ericsson white paper, 5G radio access: capabilities and technologies. By changing the phases of the sub-array signals in a certain way, this gain can be achieved in any direction, as shown in section A of Figure 3. Ericsson has announced it has inked another China Mobile deal, extending its 5G radio access network (RAN) partnership and charged with 5G core components for the second phase of … 3 dB). In suburban/rural scenarios, where vertical beamforming is usually not needed, the performance of a more cost efficient AAS with fewer radio chains is often sufficient. Steedan MA354 – Low Profile, 4-in-1 Magnetic Mount Combination Antenna with 2*5G/4G MIMO and 2*Wi-Fi 6 MIMO Add to Compare; Steedan MA350 – Low Profile, 5-in-1 Magnetic Mount Combination Antenna with Active GNSS, 2*5G/4G MIMO and 2*Wi-Fi 6 MIMO Add to Compare; Steedan 3-in-1 Magnetic Mount Combination Antenna with GNSS, 5G/4G & Wi-Fi Add to Compare; Steedan – Low Profile 3-in-1 … He joined Ericsson Research in 1998, where he worked with research and standardization of 3G and 4G physical layer with a special interest in MIMO and beamforming technologies. Vertical beamforming, however, does not provide any significant gains as the vertical user spread is low. Also, as the number of users grows, the SINR will further deteriorate due to mutual interference between the users. In multi-path scenarios, where the radio channel comprises multiple propagation paths from transmitter to receiver through diffraction around corners and reflections against buildings or other objects, it is beneficial to send the same data stream in several different paths (direction and/or polarization) with phases and amplitudes controlled in a way that they add constructively at the receiver [5]. Whereas basic beamforming has relatively low requirements on the necessary channel knowledge, generalized beamforming has higher requirements as more details about the multi-path propagation are needed. Ericsson Radio System comprises hardware, software and services for radio, RAN Compute, antenna system, transport, power, enclosure and site solutions– all run by a common management system. He received his Ph.D. in signal processing from KTH Royal Institute of Technology in 1999 and has been with Ericsson since 2001, where he has held various positions in both research and product development. Figure 1: Beamforming and MIMO, with the different colors of the filled beams representing streams. Ericsson Spectrum Sharing completely transforms the way 5G is introduced across the world. in electronic engineering from the National University of Ireland, Galway, and an M. Eng. Partitioning the antenna into small sub-arrays results in high-gain beams that can be steered over a large range of angles and effectively addresses the interference problems seen with conventional systems. Radio 2238 Triple-band radio … The shift to AAS is enabled by technology advances in the integration of baseband, radio, and antenna, and a reduction in the digital processing cost of advanced beamforming and MIMO. Reciprocity-based beamforming schemes will work for most users, but there will be users with poor coverage that need to rely on techniques such as feedback-based beamforming. Ericsson has announced two new active-passive antenna (APA) designs with integrated radio. Spatial multiplexing, here referred to as MIMO, is the ability to transmit multiple data streams, using the same time and frequency resource, where each data stream can be beamformed. Expand Collapse. Since each sub-array is normally connected to two radio chains and each radio chain is associated with a cost in terms of additional components, it is important to consider the performance benefits of additional steerability when choosing a cost-efficient array structure. The 5G glass antenna's small size and transparent appearance allow it to be installed unobtrusively in buildings, vehicles, etc. Ericsson Spectrum Sharing introduces a new way of rolling out 5G that re-uses hardware/spectrum/sites, increases coverage of mid/high band, and offer a clear path to 5G stand alone, allowing operators to shift capex investments from new sites to new 5G stand alone use cases. The key components to make this data call a success include Ericsson’s commercial radio hardware loaded with special extended-range software, Qualcomm’s Snapdragon X55 5G Modem-RF System with the QTM527 mmWave antenna module, housed in a fixed wireless access (FWA) customer-premises equipment (CPE), presumably supplied by the broadband technology company Casa Systems. The system includes hardware, software and services for radio, RAN Compute, antenna system, transport, power, enclosure and site solutions. Ericsson plans to cut about 400 jobs in the next year at the antenna … Radio 8823 8T/8R radio 3.5GHz band. Knowledge of the radio channels between the antennas of the user and those of the base station is a key enabler for beamforming and MIMO, both for UL reception and DL transmission. (Image Source: Bevin Fletcher/Wireless Week) The Hybrid AIR single box solution means less time and complexity to secure 5G site approval, and consequently, easier and cost-effective deployments. He later moved to the Systems & Technology organization to work closer to the implementation of multi antenna technologies. Channel estimates can be used to determine how to combine the signals received to improve the desired signal power and mitigate interfering signals, either from other cells or within the same cell in the case of MU-MIMO. To see how an antenna array creates steerable high-gain beams, we start with an antenna array of a specific size, which is then divided into sub-arrays of different sizes.

DL longer-term channel knowledge (such as dominant directions) can, however, be obtained by suitable averaging of UL channel estimate statistics. He has an M.Sc. This scenario calls for an AAS with a large antenna area and the ability to support horizontal beamforming. AAS enables state-of-the-art beamforming and MIMO techniques that are powerful tools for improving end-user experience, capacity and coverage. Ericsson said its five-year deal with T-Mobile will see it supply equipment, software and related services to expand and enhance the telco’s 5G footprint. Anders FuruskärAnders Furuskär joined Ericsson Research in 1997 and is currentlya senior expert focusing on radio resource management and performanceevaluation of wireless networks. It has unveiled two new radios for its AIR (antenna-integrated radio) family, which are designed to make it quicker, easier and cheaper to deploy midband 5G at scale. This is referred to as reciprocity-based beamforming. AIR 4488 Triple-band antenna, 4T/4R, 3 bands, low-band and mid-band, 7 frequency bands AIR4488 3. Erik LarssonErik Larsson joined Ericsson in 2005. To distinguish between DL layers, a UE needs to have at least as many receiver antennas as there are layers. The total number of elements determines the maximum gain and the sub-array partitioning allows steering of high gain beams over the range of angles. The gain is achieved, in both UL and DL, by constructively combining signals from a number of antenna elements. Another main driver for AAS is the need to meet coverage requirements on new and higher frequency bands. AIR 8828 FDD AIR8828. End-user performance requirements continue to increase, putting high demands on the radio access network (RAN) to deliver increased coverage, capacity and end-user throughput. In dense urban high-rise scenarios with tall buildings and high subscriber density, an AAS with beamforming capabilities in both vertical and horizontal directions is the most beneficial option. As a result, the importance of AAS is likely to increase rapidly in future radio network deployments, [1] 5G NR: The Next Generation Wireless Access Technology, 1st Edition, August 2018, Dahlman, E; Parkvall, S; Sköld, J, available at: https://www.elsevier.com/books/5g-nr-the-next-generation-wireless accesstechnology/dahlman/978-0-12-814323-0, [2] NR - The New 5G Radio-Access Technology, Stefan Parkvall, Erik Dahlman, Anders Furuskär, Mattias Frenne, 2018 IEEE 87th Vehicular Technology Conference: VTC2018- Spring, 3–6 June 2018, Porto, Portugal, [3] Fredric Kronestedt, Henrik Asplund, Anders Furuskär, Du Ho Kang, Magnus Lundevall, Kenneth Wallstedt, The advantages of combining NR with LTE at existing sites, Ericsson Technology Review, available at: https://www.ericsson.com/en/ericsson-technology-review, [4] Barry D.

The achievable capacity gains from MU-MIMO depend on receiving each layer with good signal-to-interference-and-noise-ratio (SINR). The 5G site grid needs to provide wide mid-band capacity while re-using established sites and minimizing additional footprint. in electrical engineering and engineering physics from Linköping University (Sweden) and a Ph.D. in in electrical engineering from the University of Tokyo, Japan. Furthermore, mitigating interference in terms of null forming for MU-MIMO is even more challenging, since more channels typically need to be characterized with high granularity and accuracy. For FDD, where different frequencies are used for UL and DL, the channel is not fully reciprocal. The innovative solution, tested on a live network, was made possible thanks to the new Ericsson 5G mmWave high power antenna-integrated radio AIR 5322, installed at the mobile site on Via Oriolo Romano in Rome, equipped with Ericsson’s extended range software. Ericsson said mobile networks increasingly depended on antenna technology, with more integration of antennas and radios and increasing use of active antennas in next-generation 5G. New 20+1-Port Passive Antenna with 2L8M Bands Antenna 6600 2L 8M 2.0m. Many MNOs choose this strategy as it is often difficult, time consuming and expensive to acquire and deploy new sites. A small number of AAS variants provide significant benefits across a very wide range of deployment scenarios, making it possible for mobile network operators to enjoy the benefits of cost-efficient AAS across their networks. Rural or suburban macro scenarios, as depicted in section C of Figure 4, are characterized by rooftop or tower-mounted base stations with inter-site distances ranging from one to several kilometers, low or medium population density and very small vertical user distribution. The urban low-rise scenario illustrated in section B of Figure 4 represents many of the larger cities around the world, including the outskirts of many high-rise cities. Swisscom is the leading provider of communication, IT and entertainment in Switzerland. https://www.ericsson.com/.../advanced-antenna-systems-for-5g-networks Modern Slavery Statement | Privacy | Legal | © Telefonaktiebolaget LM Ericsson 1994-2021, “At Swisscom, we have rolled out 5G capacity across Switzerland. The array gain is referred to as the gain achieved when all sub array signals are added constructively (in phase). Radio 4408 for TDD. Compared to the dense urban high-rise scenario, traffic per area unit is lower. In 2016, he earned an MBA from Leicester University in the UK. 2. He holds both an M.Sc.
