Written on Wednesday, 25 October 2017 12:41

US Cellular, the fifth-largest full-service wireless carrier in the United States, and Ericsson, have completed a joint testing of various 5G use cases at 28GHz. The tests, a significant step toward the launch of a 5G network, were conducted in rural and suburban environments in Madison, Wisconsin.

The trials were conducted under a variety of real-world conditions, and they achieved peak throughput speed of 8.5Gbps. In addition, virtual reality was tested, achieving peak speeds of 4Gbps. This virtual reality test was one of the highlights of the trial, as it proved how the ultra-high speeds and low latency of 5G will enable VR applications.

The companies also tested augmented reality, advanced beamforming and Massive MIMO. The live over-the-air trials expanded on 5G trials between the two companies in 2016 that achieved 9 Gbps at 15GHz.

“This was an important trial for us to understand the propagation characteristics and path loss at 28Ghz, and we are pleased with our learnings,” said Michael S.

At the 2017 Global Antenna Technology & Industry Forum recently held in Munich, Huawei partnered with Telefónica Deutschland to launch the world's first 5G-oriented antenna deployment solution. During the evolution to 5G, this solution can resolve the challenge of insufficient antenna installation space for the deployment of both high-band 4T4R over Sub 3 GHz and Massive MIMO.

"Based on many years of technical accumulation in wireless networks and an in-depth understanding of MBB network, Huawei cooperates with Telefónica Deutschland to release the world's first 5G-oriented antenna deployment solution,” said Mr. Joyee Zhang, President of Huawei Wireless Network Antenna Business Unit. “This innovative solution can help operators to overcome the obstacles of 5G network deployment and potentially further help to achieve new business success.”

Insufficient antenna installation space has emerged as an evident issue of network deployment during the evolution from 4G to 4.5G/5G. As 700 MHz, 1400 MHz and other new spectrums are distributed, full bands 4T4R has emerged as a mainstream configuration. Simple overlay can hardly meet deployment requirements.

Additionally, operators are expected to reserve antenna installation space for Massive MIMO to implement a smooth evolution. As a result, a single antenna that integrates all Sub 3 GHz bands and reserves space for Massive MIMO is set to be a typical antenna solution for 5G.

Huawei and Telefónica Deutschland jointly released a 5G-oriented antenna deployment solution, which incorporates both a 14-port multi-band antenna and a TDD 3.5 GHz Massive MIMO antenna to meet Telefónica's requirements for an easy network evolution towards 5G.

Mr. Jaime Lluch, Radio Access Network Director in Telefónica Deutschland indicated that, "Telefónica is a top global telecom operator committed to deliver an optimal network experience. We believe that during the future-oriented network evolution of MBB, antenna installation space severely hinders the progress of network deployment. Telefónica Deutschland and Huawei's 5G-oriented antenna deployment solution can address the challenge of insufficient space, while ensuring excellent network performance and capacity.”

At Mobile World Congress Americas, US telecom provider Sprint and Ericsson unveiled the results of the first US 2.5GHz Massive MIMO (multiple input, multiple output) field tests conducted in Seattle, Washington and Plano, Texas using Sprint’s spectrum and Ericsson’s 64T64R (64 transmit, 64 receive) radios.

Sprint and Ericsson are preparing for commercial deployment next year, with Massive MIMO capable of increasing Sprint’s network capacity up to ten times. Testing of Massive MIMO on the Sprint LTE Plus network in downtown Seattle showed a capacity increase of approximately four times compared to an 8T8R antenna.

To showcase this capacity, Sprint convened 100 people with Samsung Galaxy S7 phones and ran simultaneous file downloads on a timed-test on all networks. The testing showed a 100 percent success rate on the Massive MIMO-powered Sprint network, which was a significantly higher result compared to the other networks.

In Plano, Texas, Sprint and Ericsson also recently tested Ericsson’s 64T64R Massive MIMO radios reaching peak speeds of more than 300 Mbps using a single 20 MHz channel of 2.5 GHz spectrum.

For both field trials, Ericsson provided the radio network infrastructure and backhaul equipment. Sprint and Ericsson together developed the test cases and requirements, which included a variety of performance scenarios involving multi-user and non-stationary testing. 

The Radio Network infrastructure included Ericsson’s next-generation 5G-ready AIR6468 radio, and the backhaul equipment utilized the MINI-LINK 6352 R2 microwave radios which can provide up to 10 Gbps of backhaul, future proofing the network for 5G.

“Massive MIMO is a game changer for adding capacity to our network and taking LTE Plus to the next level,” said Dr. John Saw, Sprint CTO. “This technology is a tremendous competitive advantage for Sprint, enabling us to maximize our deep 2.5 GHz spectrum holdings. Massive MIMO will be key to meeting our customers’ growing demand for unlimited data, as well as offering Gigabit LTE and 5G services.”

The companies will use the field trial results in preparation for commercial deployment of Massive MIMO in the US beginning in 2018. In cities across the US, Sprint plans to deploy 64T64R Massive MIMO radios using its 2.5 GHz spectrum to increase capacity up to ten times.

The technology will become part of Sprint’s extended network toolbox as it works to densify and optimize the network, providing more capacity, better reliability, and overall improved performance for customers. In addition, Massive MIMO is slated to power Gigabit LTE services, and it will be a key element of Sprint’s 5G network.

“Ericsson and Sprint have been collaborating on new technologies and continually evolving Sprint’s LTE network, laying the foundation for 5G,” said Nishant Batra, Head of Network Infrastructure at Ericsson.

“Our next-generation 5G-ready TDD 64T64R Massive MIMO radio (AIR6468) will help maximize spectral efficiency of Sprint’s 2.5 GHz network,” Batra added. “It will also provide a cost-efficient way to support their customers’ growing appetite for increased capacity and high-speed data services. This will be the industry’s first live eCPRI installation, which allows for several deployment and performance advantages to operators in the 5G era.”

Massive MIMO is a differentiator for Sprint because it can be easily deployed on high-band spectrum such as Sprint’s 2.5 GHz spectrum. Massive MIMO radios can support high-frequency bands with a small form factor, whereas the physics of lower-frequency spectrum bands would require radios far too large in size to manufacture and deploy on a broad scale.

Ericsson enhances global 5G radio offering

Written on Monday, 11 September 2017 13:00

Ericsson has enhanced its global 5G radio offering by introducing a new radio product, AIR 3246, for Massive Multiple Input Multiple Output (Massive MIMO). The product supports both 4G/LTE and 5G New Radio (NR) technologies and is Ericsson’s first 5G NR radio for frequency division duplex (FDD).

The product launch, according to the Swedish telecom equipment manufacturer, will enable operators – especially in metropolitan areas – to bring 5G to subscribers using currently available mid-band spectrum and boost capacity in their LTE networks.

Ericsson’s 5G Platform includes three previously launched time division duplex (TDD) radios capable of supporting 5G and Massive MIMO, as well as core, transport, digital support and security elements. The company claims to have the most complete 5G portfolio in the industry, serving the needs of the first movers in 5G.

“We now expand the 5G platform that we introduced last February,” said Fredrik Jejdling, Head of Business Area Networks at Ericsson. “The new radio will enable operators to enhance 4G capacity for their subscribers today and be ready for 5G tomorrow, using the same hardware. We also complement the products with a set of network services, simplifying the journey to 5G for our customers.”

Bridging from 4G to 5G

People are watching, sharing and streaming video and music more than ever. As such, the demands on a sufficient speed are ever increasing. Ericsson analyzed 4G network performance statistics from metropolitan areas around the world, and found that the probability of a smart device suffering from insufficient speed can be as high as 20 percent during peak hours.

Massive MIMO, Ericsson claims, is a key technology to bridge from 4G to 5G, adding intelligent capacity and boosting user experience.

“Just as carrier aggregation has been key to adding needed capacity to mobile broadband networks, Massive MIMO has the potential to be the primary capacity enabler in the next upgrade phase, providing a smooth transition towards 5G,” says Stefan Pongratz, Senior Director at the Dell’Oro Group.

“With an expected 2021 installed base of 10M LTE macro radios in high traffic and metro areas, service providers are expected to capitalize on the improved spectral efficiency made possible with Massive MIMO,” Pongratz added.

FDD Massive MIMO is part of a trial with T-Mobile US, on three sites in Baltimore, Maryland. This will be the first time that standardized Massive MIMO will be used to carry commercial LTE traffic using mid-band FDD spectrum.

Neville Ray, Chief Technology Officer for T-Mobile, said the operator is “racing forward at breakneck pace with Ericsson’s next-gen tech that advances LTE today and paves the way for 5G tomorrow.”

Massive MIMO on FDD can increase network capacity up to three times and bring up to five times better user throughput, boosting performance for the end users. Today’s global base is primarily on FDD technology and devices, which separates uplink and downlink streams on different radio frequencies.

Commercially available in the second quarter 2018, AIR 3246 will be part of Ericsson Radio System. Ericsson’s 5G platform comprises the 5G core, radio and transport portfolios, together with OSS, BSS, network services and security.
