Finland’s Elisa, Ericsson and Qualcomm test uplink carrier aggregation on 5G SA network

With Ericsson and Qualcomm doing the “heavy lifting,” Finland network operator Elisa conducted a live test of uplink carrier aggregation (CA) on its commercial 5G standalone (SA) network.  Elisa operates commercial 5G SA networks, starting with its home market of Finland and following it up last year by deploying it in Estonia.

The three partners achieved an upload speed of 230 Mbps in a live 5G network using Uplink Carrier Aggregation. For this test, a 25MHz 2.6 GHz FDD (frequency division duplex) band was combined with a 100MHz 3.5 GHz TDD (time division duplex) band running on a mobile test device powered by Snapdragon® X75 5G Modem-RF System.

Ericsson’s Uplink Carrier Aggregation software combines mid-band FDD and mid-band TDD within the frequency range 1 (FR1), boosting speeds to enable uplink-heavy applications such as live streaming, broadcasts, cloud gaming, extended reality, and video-based use cases.

Uplink-heavy consumer applications on the rise:

According to Ericsson’s most recent Mobility Report, uplink accounted for a modest 8% of total traffic on a sample of four mobile networks analyzed. The applications that generated the largest volume of uplink traffic were personal cloud storage services, followed by comms services and video.

While 8% doesn’t seem like much, Ericsson emphasised that uplink volume is highly context dependent. For instance, there is likely to be more of it at a live event, like a concert or a sporting event, where users enthusiastically film and then share as much action as possible.

A growing amount of data traffic generated today is in the uplink, highlighting the need for new network capabilities to boost uplink speed and capacity and deliver seamless 5G user experience. For instance, concertgoers are recording and streaming videos live on their social media accounts. With fast uplink speeds, they can share their most exciting moments in real-time with friends and family without worrying about lags, congestion, or poor network quality.

In addition to Elisa, Vodafone has also been testing out uplink CA recently, as have DishBT and Telefónica.

T-Mobile US, Ericsson, and Qualcomm test 5G carrier aggregation with 6 component carriers

T-Mobile US, in a partnership with Ericsson and Qualcomm Technologies, has successfully tested the aggregation of six component carriers in sub-6 GHz spectrum in its live production 5G network.

The test involved aggregating two channels of 2.5 GHz, two channels of PCS spectrum and two channels of AWS spectrum, according to T-Mobile US, which produced an “effective 245 MHz of aggregated 5G channels.”

T-Mo said that they were able to “achieve download speeds of 3.6 Gbps in sub-6 GHz spectrum.  That’s fast enough to download a two-hour HD movie in less than 7 seconds!”

5G carrier aggregation allows T-Mobile to combine multiple 5G channels (or carriers) to deliver greater speed and performance. In this test, the Un-carrier merged six 5G channels of mid-band spectrum – two channels of 2.5 GHz Ultra Capacity 5G, two channels of PCS spectrum and two channels of AWS spectrum – creating an effective 245 MHz of aggregated 5G channels.

“We are pushing the boundaries of wireless technology to offer our customers the best experience possible,” said Ulf Ewaldsson, President of Technology at T-Mobile. “With the first and largest 5G standalone network in the country, T-Mobile is the only mobile provider serving 10s of millions of customers to unleash new capabilities like 5G carrier aggregation nationwide, and I am so incredibly proud of our team for leading the way.”

T-Mobile US announced in May of 2023 that it was rolling out four component-carrier aggregation across its 5G Standalone network, which it said at the time can achieve peak speeds of 3.3 Gbps. In that case, T-Mobile US relies on two 2.5 GHz channels, one 1.9 GHz channel and one 600 MHz channel. The first device able to access 4CA capabilities was the Samsung Galaxy S23.

The carrier also touted its testing of five-component-carrier aggregation in sub-6 GHz spectrum at last year’s Mobile World Congress Barcelona. In that trial, working with Nokia and Qualcomm, T-Mo aggregated two FDD and three TDD carriers and achieved peak downlink throughput speeds that exceeded 4.2 Gbps.

T-Mobile claims to be the leader in 5G, delivering the country’s largest, fastest and most awarded 5G network. The Un-carrier’s 5G network covers more than 330 million people across two million square miles — more coverage area than AT&T and Verizon combined. 300 million people nationwide are covered by T-Mobile’s super-fast Ultra Capacity 5G with over 2x more square miles of coverage than similar offerings from the Un-carrier’s closest competitors.

Dish Wireless with Qualcomm Technologies and Samsung test simultaneous 5G 2x uplink and 4x downlink carrier aggregation

Dish Wireless collaborated with Qualcomm Technologies and Samsung to successfully test simultaneous 5G 2x uplink and 4x downlink carrier aggregation (CA) using FDD spectrum.  DISH achieved 200 Mbps uplink peak speeds with just 35 MHz of 5G spectrum.  The DISH 5G network executed 1.3 Gbps downlink peak speeds with just 75 MHz of 5G spectrum, both across FDD bands n71, n70 and n66.  Boost Mobile and Boost Infinite subscribers will soon benefit with even faster download and upload speeds on America’s Smart Network™.

This test was completed in both DISH labs and the field using a mobile phone form-factor test device powered by Snapdragon® X75 5G Modem RF System from Qualcomm Technologies [1.] and Samsung’s 5G vRAN solution as well as dual- and tri-band radios across the DISH 5G network.

Note 1.  Qualcomm’s Snapdragon X75is currently sampling to customers with commercial devices expected to launch later this year.

“It’s been a pleasure to work closely with DISH Wireless and support their expanding cloud-native Open RAN virtualized network as 5G services are now live across several markets, clearing the path for even lower latency and faster speeds,” said Mark Louison, executive vice president and general manager, Networks Business, Samsung Electronics America. “We are committed to pushing the boundaries to advance network capabilities to meet growing consumer demands for our customers.”

“We look forward to continued collaborative efforts with industry partners such as DISH and Samsung to enable faster 5G around the world,” said Sunil Patil, vice president, Product Management, Qualcomm Technologies, Inc. “As consumers demand increases for uplink heavy applications, carrier aggregation on FDD spectrum is crucial to bring faster upload speeds to more consumers across markets and networks.”

……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………

DISH claims its “Open RAN cloud-native 5G network is changing the way the world communicates,” but we don’t believe that is happening and we are not proponents of OpenRAN.

“The DISH 5G Open RAN network now covers over 73% of the U.S. population 5G broadband coverage and more than 100 million Americans 5G voice service – VoNR – with more markets going live each month,” said Eben Albertyn, EVP and CTO, DISH Wireless. “By successfully delivering 5G 2x uplink and 4x downlink carrier aggregation for FDD spectrum, DISH is now poised to deliver a better customer experience across our 5G standalone network. We look forward to continuing to pave the way to fully harness the power of 5G.”

……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………

According to Daryl Schoolar, analyst and director at Recon Analytics, this achievement is significant for Dish because while operators have been able to do downlink CA using multiple FDD bands, uplink CA is very new.  DISH’s announcement comes just a little over a month after Qualcomm and Samsung announced that they had completed the world’s first simultaneous 5G 2x uplink and 4x downlink CA for FDD spectrum. Qualcomm and Samsung noted at the time that this development was important because it gives operators with fragmented FDD spectrum assets more flexibility and makes it possible for them to deliver faster upload and download speeds.  Traditionally, uplink CA has been accomplished by combining FDD+TDD or TDD+TDD configurations.

Schooler added that Dish’s announcement demonstrates that this capability can be delivered over a commercial 5G network and Dish will benefit from it as it grows its subscriber base. “Increasing network capacity will be important given that Dish trails its three largest U.S. mobile competitors in lower-spectrum holdings,” he said.

Uplink capacity is becoming more critical as more consumers use uplink-heavy applications such as social media posting and video conferencing.  Indeed, the possibility of delivering peak uplink speeds of 200 Mbps is quite a sizable increase from typical uplink speeds that are measured on wireless networks today. In Ookla’s Q3 2023 report on U.S. wireless networks, it reported that T-Mobile had the fastest median upload speed in the U.S. with speeds of just 11.31 Mbps.

BT, Nokia and Qualcomm demonstrate 2CC CA on uplink of a 5G SA network

UK incumbent telco BT announced today that it has successfully demonstrated two component carrier aggregation (2CC CA) on the uplink of a 5G SA network at its Adastral Park research centre.  The 5G SA technology was supplied by Nokia and Qualcomm.

BT also simultaneously achieved 4CC CA on the downlink, and claims it is the first telco in Europe to have demonstrated 5G SA uplink and downlink carrier aggregation at the same time. In terms of throughput, BT recorded a peak download speed of 1 Gbps and peak upload of 230 Mbps.

  • BT Group and Nokia demonstrated enhanced 5G SA uplink performance through aggregation of two spectrum carriers in field trial in live network spectrum
  • Aggregation of two frequency bands for uplink boosts performance for EE’s future 5G SA network, key to supporting growing customer use-cases such as gaming and live-streaming
  • BT Group first in Europe to achieve both 2CC CA uplink and 4CC CA downlink simultaneously

When BT detailed its wideband FDD trial, it noted that the 5G SA specification from 3GPP is currently based on a single uplink carrier, so why try and aggregate uplink carriers?  BT said that uplink carrier aggregation is something to have handy in future, when data demand inevitably calls for ever more uplink capacity.

5G Carrier Aggregation over a 5G SA network, which combines several transmission bands into one connection, is a key capability to deliver the high-performance 5G service that customers expect. Every new carrier added allows for higher capacity and speed directly to customer devices.

Last year, BT and Nokia announced 5G SA 4CC CA downlink. Now, by achieving both 5G SA 2CC CA uplink and 4CC CA downlink simultaneously, BT can deliver significant uplift in connections performance from the device to the network by increasing throughput and capacity, as well as unlocking scope to push uplink performance further in the future.

The tests were conducted at BT Group’s facility in Adastral Park, UK, using Nokia’s 5G AirScale portfolio and a device powered by a Snapdragon® 5G Modem-RF System from Qualcomm Technologies, Inc., following initial lab-based trials.* Speeds of over 230 Mbps in the uplink were reached — including the wider 5G FDD carrier at 40 MHz in 2600 MHz — as well as over 1 Gbps in the downlink. The demonstration was conducted with 15, 30 and 40 MHz NR2600 carrier independently aggregated with a 40 MHz NR3500 carrier component.

The work is part of BT Group’s efforts to ensure that, when 5G SA services are launched over EE, it maintains its unbeatable 5G network for customers.**

Greg McCall, Chief Networks Officer, BT Group, commented: “Carrier aggregation will be key to delivering the very best 5G experience to our customers, with this latest trial in partnership with Nokia demonstrating significant performance increases in terms of uplink speeds. This builds on last year’s success of achieving 4CA in 5G SA downlink, and we look forward to achieving further milestones in this space as we continue to progress towards 5G SA.”

Mark Atkinson, SVP, Radio Access Networks PLM at Nokia, said: “This successful trial with our long-standing partner BT, is another great example of Nokia’s unrivalled leadership in 5G carrier aggregation technology. Multi-component carrier aggregation helps mobile operators to maximise their radio network assets and provide the highest 5G data rates to subscribers in more locations.”

Enrico Salvatori, Senior Vice President and President, Qualcomm Europe/MEA, Qualcomm Europe Inc, said: “We are proud of our continued collaboration with BT to bring our latest 5G technologies to consumers. 2CC uplink carrier aggregation is expected to improve uplink speeds by up to 2X, to give a better user experience overall.  Consumers would potentially be able to upload and share higher quality videos faster online, such as when attending concerts and when watching and streaming games online. We look forward to the future and what else is to come with our continued collaboration with BT.

BT tests 4CC Carrier Aggregation over a standalone 5G network using Nokia equipment

BT announced Monday that it has successfully tested four component-carrier (4CC) carrier aggregation on a 5G Standalone (SA) network in commercial frequencies. Using EE’s live network, BT said it and Nokia were able to combine four low-band and mid-band radio channels in and 2 GHz and 3 GHz range. BT claims to be the first operator in Europe to achieve this feat, calling this particular demonstration of advanced carrier aggregation “a major leap forward” for the evolution of 5G.  Carrier aggregation is seen as the key to achieving optimal data transmission speeds for 5G.  

“As we migrate to a 5G standalone core network, this technology milestone is vital to giving our customers the best experience” commented Greg McCall, Managing Director of Service Platforms at BT.

Working in collaboration with Nokia, BT’s Networks team have successfully combined four low-band and mid-band radio channels, (2.1, 2.6, 3.4, 3.6 GHz), using Nokia’s 5G Radio Access Network technology in EE’s live network spectrum.

The trial was conducted in two stages; it was first performed in BT’s Radio Lab in Bristol, and then moved outdoors, onto a radio mast at BT’s Adastral Park in Suffolk, where the team successfully achieved 4CC on 5G SA radiating in EE’s regular radio spectrum. Not only is it the first time in Europe that a network operator has achieved 4CC on 5G SA using commercial spectrum, but it is also the first time it has been achieved outside of a lab in Europe.

Most 5G networks today are Non-Standalone (“NSA”), meaning 5G is supported by existing 4G infrastructure. 5G Carrier Aggregation (“CA”) over a standalone 5G network represents a major leap forward in the evolution of 5G infrastructure, effectively combining several transmission bands into one connection. Every new carrier added allows for higher capacity and speed directly to customer devices.

Greg McCall, Managing Director Service Platforms BT, commented: “Our trial with Nokia is another demonstration of building the most advanced network for our customers. 5G Standalone, coupled with edge compute, will unlock new opportunities for customers looking to develop new services. Furthermore, this technology showcases what’s possible for devices in the future in terms of supporting carrier aggregation, which is an important part of customer experience.”

“Carrier Aggregation (CA) means combining or aggregating several carriers within or across available frequency bands – referred to as component carriers – for achieving higher data rates. Each additional component carrier increases the available bandwidth and, therefore, improves throughput. In the case of carrier aggregating Frequency-Division Duplex (FDD) and Time-Division Duplex (TDD) spectrum together, this also enables a value-adding solution that “stretches” the site coverage area that can offer those higher data rates,” said Nokia.

Mark Atkinson, SVP, Radio Access Networks PLM, Nokia, commented: “We are once again delighted to be deepening our partnership with BT, supporting them with our industry-leading Carrier Aggregation technology for this trial. Nokia and BT have a long history in investing in cutting-edge technologies and this trial is another example of what our companies can achieve together.”

 

Greg McCall, managing director of service platforms at BT, said the test showcases demonstrates his company’s commitment to building out the most advanced mobile network.

“5G Standalone, coupled with edge compute, will unlock new opportunities for customers looking to develop new services,” said McCall.

In May, Australian mobile operator Optus, Nokia, and Samsung Electronics Australia announced a successful test of three-component-carrier (3CC) CA technology over a 5G SA network. At the time, Nokia noted its commitment to prioritize the development of 5G carrier aggregation across the sub-6 GHz 5G spectrum. At the time, Nokia used its latest commercial AirScale Baseband and radio portfolio over Optus’ commercial network. The trial combined the FDD band (2.1 GHz) with the TDD band (2.2 GHz + 3.5 GHz) using CA technology.

T-Mobile US achieves speeds over 3 Gbps using 5G Carrier Aggregation on its 5G SA network

T-Mobile US said it was able to aggregate three channels of mid-band 5G spectrum, reaching speeds over 3 Gbps on its standalone 5G network. It’s the first time the test has ever been done with a commercial device, here the Samsung Galaxy S22 powered by Snapdragon 8 Gen 1 Mobile Platform with Snapdragon X65 Modem-RF System), on a live production network, the company said.

5G Carrier Aggregation (New Radio or NR CA) allows T-Mobile to combine multiple 5G channels (or carriers) to deliver greater speed and performance. In this test, the carrier merged three 5G channels – two channels of 2.5 GHz Ultra Capacity 5G and one channel of 1900 MHz spectrum – creating an effective 210 MHz 5G channel.

The achievement is only possible with standalone 5G architecture (SA) and is just the latest in a series of important SA 5G milestones for T-Mobile. The carrier said it was the first in the world to launch a nationwide SA 5G network nearly two years ago. The carrier began lighting up Voice over 5G (VoNR) this month so that all services can run on 5G. By removing the need for an underlying LTE network and 4G core, 5G will be able to reach its true future potential with incredibly fast speeds, real-time responsiveness and massive connectivity, the company mentioned.

NR CA is live in parts of T-Mobile’s network today, combining two 2.5 GHz 5G channels for greater speeds, performance and capacity. Customers with the Samsung Galaxy S22 will be among the first to experience a third 1900 MHz 5G channel later this year. This functionality will expand across the carrier’s network and to additional devices in the near future.

T-Mobile US  was the first in the world to launch a nationwide SA 5G network nearly two years ago and has been driving toward a true 5G-only experience for customers ever since. Just this month the Un-carrier began deploying Voice over 5G (VoNR) so ALLvoice services can run on 5G. By removing the need for an underlying 4G LTE network and 4G core, 5G will be able to reach its true future potential with incredibly fast speeds, real-time responsiveness and massive connectivity.  The carrier’s 5G network covers 315 million people across 1.8 million square miles. 225 million people nationwide are covered with super-fast Ultra Capacity 5G, and T-Mobile expects to cover 260 million in 2022 and 300 million next year.  It also has the fastest 5G network, according to Ookla speed tests in Q4 2021:

Note that neither Verizon or AT&T have deployed 5G SA core networks with no future dates specified.

Extended-range 5G NR data call over mmWave completed; Ericsson & Qualcomm test 5G SA Carrier Aggregation

Qualcomm Technologies, Casa Systems and Ericsson announced that the companies successfully completed what they call the world’s first extended-range 5G NR data call over mmWave. The extended range data call was completed in Regional Victoria, Australia on 20 June, achieving a farthest-ever connection of 3.8 kilometers (km).

This so called “breakthrough” from Qualcomm Technologies, Casa Systems and Ericsson provides global network operators and ISPs with the reach and performance to offer fixed broadband wireless as a “last mile” access technology.  Of course, line of sight communications (i.e. no trees, walls or other blockages permitted). With the increased range demonstrated for mmWave, that technology may be suitable for fixed wireless access (FWA) as well as for 5G mobile service in suburban or even rural areas that won’t require as many small cells or high density cell towers.

Network operators will have the potential to use their existing mobile network assets to deliver fixed wireless services and expand their service with ease to new areas, from urban to rural, while delivering 5G’s multi-gigabit speeds and ultra-low latency to a wider customer base within their coverage footprint. In addition, this milestone will proliferate the roll-out of FWA customer-premises equipment (CPE) devices to areas that are often too difficult to reach with traditional broadband, including rural and suburban areas, empowering more customers across the globe to access superior connectivity at fiber optic-like speeds.

The extended-range data call was achieved by applying extended-range software to commercial Ericsson hardware – including Air5121 and Baseband 6630 – and a 5G CPE device powered by the Qualcomm Snapdragon X55 5G Modem-RF System with the Qualcomm QTM527 mmWave antenna module.

5G mmWave: facts and fictions you should definitely know

“With the introduction of the Qualcomm QTM527 mmWave antenna module as part of the Snapdragon X55 5G Modem-RF System, we are empowering operators and OEMs to offer high-performance, extended-range multi-gigabit 5G broadband to their customers – which is both flexible and cost-effective, as they can leverage existing 5G network infrastructure,” said Gautam Sheoran, senior director, product management, Qualcomm Technologies, Inc. “With this major milestone being the first step in utilizing mmWave for an extended-range 5G data transfer, our collaboration with Casa Systems and Ericsson is paving the way to implement fixed broadband services for broad coverage in urban, suburban and rural environments.”

“As operators look to close the digital divide and expand broadband services throughout rural, suburban and urban communities, the technology in this data connection underscores the critical role mmWave will play in the global proliferation of 5G networks,” said Steve Collins, senior vice president, access devices, Casa Systems. “This collaboration with Qualcomm Technologies and Ericsson is an industry milestone that makes it possible for operators to offer multi-gigabit broadband services wirelessly as a new broadband alternative solution using mmWave spectrum, and we look forward to delivering innovative CPE devices that further empowers the global broadband delivery ecosystem.”

Ericsson has a long history of working with extended range across generations of mobile technologies, pioneering with 3G, then 4G and now with 5G. By collaborating with leading industry partners like Qualcomm Technologies and Casa Systems, we are able to ensure that everyone can access the transformative benefits of 5G connectivity. This achievement will open up opportunities for communications service providers around the world and how they can use mmWave spectrum for long-range use cases,” said Per Narvinger, head of product area networks, Ericsson.

5G SA Carrier Aggregation from Qualcomm & Ericsson:

Today’s announcement comes just three days after Qualcomm and Ericsson announced that they completed interoperability tests for 5G standalone (SA) carrier aggregation. Carrier aggregation allows operators to use multiple sub-6 GHz spectrum channels simultaneously to transfer data between base stations and a 5G mobile device.

The test was completed at Ericsson’s labs in Beijing, China. The connection reached 2.5 Gb/s peak speeds by aggregating 100 MHz and 60 MHz within the 2.5 GHz (n41) TDD band in a 70% downlink configuration and using 4×4 multiple-input multiple-output (MIMO) technology.  In Sweden, the two companies established a successful 5G SA carrier aggregation data call by combining 20 MHz in the 600 MHz (n71) FDD band with 100 MHz of spectrum in the 2.5 GHz (n41) TDD band.

Implementation of 5G carrier aggregation delivers enhanced network capacity along with improved 5G speeds and reliability in challenging wireless conditions, allowing consumers to experience smoother video streaming and enjoy faster downloads. This key 5G capability is expected to be widely deployed by operators around the world in 2021, according to Ericsson.
