Research on quantum communications using a chain of synchronously moving satellites without repeaters
Academic and industry researchers are increasingly eyeing the prospect of global communications networks that would take advantage of quantum technology. Long-distance quantum communication can be achieved by directly sending light through space using a train of orbiting satellites that function as optical lenses without using repeaters.
Some research groups are looking at satellite-based quantum communications, in which quantum information would ride on laser beams between spacecraft in low Earth orbit (LEO). However, the loss of photons in diffracting laser beams, as well as the curvature of the Earth itself, would likely limit realistic distances of high-efficiency quantum links between LEO satellites to less than 2000 km.

Recently, researchers Sumit Goswami of the University of Calgary, Canada, and Sayandip Dhara of the University of Central Florida, US, have laid out a proposal showing how those pitfalls could be overcome (Phys. Rev. Appl., doi: 10.1103/PhysRevApplied.20.024048). Their proposal involves relaying delicate quantum signals across a chain of relatively closely spaced, synchronously moving satellites. Those satellites, the pair suggests, could effectively act “like a set of lenses on an optical table,” focusing and bending beams along Earth’s curvature and preventing photon loss across distances as great as 20,000 km—without the need for quantum repeaters. Goswami said that a chain of around 160 satellites would be needed to cover the full 20,000-km distance modeled in the paper. Such a single, geostationary chain, he noted, would cover most of the globe every three days as the Earth rotated beneath the satellite array—so, Goswami said, “even just one chain can be used for connecting many places at different times.” But a larger, 2D network, to enable uninterrupted worldwide quantum communications, would require tens of thousands of new satellites.
While Goswami and Dhara metaphorically refer to the nodes in their proposed all-satellite quantum network (ASQN) as satellite lenses, in reality the optical magic happens with mirrors, to keep absorption-related photon losses to an absolute minimum. In simplified terms, a given satellite in the chain sends a beam of light to the next one, perhaps 120 km away. That next satellite captures and refocuses the beam with a receiving mirror and bounces it off of two smaller mirrors to a final transmitting mirror, which relays the signal on to the next satellite in the chain.
In their modeling, Goswami and Dhara considered a chain of satellites, each separated from the next by 120 km; given expected beam divergence in Earth orbit, that implies a telescope diameter of 60 cm for each satellite. The team’s modeling suggests that such a relay setup, using vortex beams to pass the quantum signal from satellite to satellite, would virtually eliminate diffraction loss across distances of 20,000 km.
With diffraction loss taken care of, Goswami and Dhara methodically looked at other potential sources of loss in the satellite-lens system. One obvious one is reflection loss of some photons at the mirrors themselves, which the pair thinks could be kept manageable through a configuration combining large metal mirrors and small, ultrahigh-reflectivity Bragg mirrors. Another source of loss lies in tracking and positioning errors for the satellites in the chain; such hiccups would need to be held to a minimum to keep the satellites in sync with one another.
A final source of loss has nothing to do with the satellites. Depending on the quantum communication architecture, quantum information needs to be transmitted from and to stations on Earth’s surface. For free-space optical signals, that opens the prospect of data losses due to atmospheric turbulence, which can dramatically increase the beam size and spread. Turbulence turns out to be a much bigger problem for data in the uplink (ground to satellite) than in the downlink (satellite to ground). That’s because in the uplink, the turbulence is doing its dirty work at the beginning of the communication chain rather than at its end; thus the turbulence-induced beam divergence and fragmentation is magnified across the large propagation distance of the satellite network as a whole.
Outperforming fiber—without repeaters:

For their proposed all-satellite quantum network (ASQN), Goswami and Dhara modeled two different quantum communication schemes. In one, qubit transmission (top), photons are transmitted from a ground-based source to a first satellite, relayed through space along a chain of reflector satellites, and beamed to another ground station, with beam diffraction controlled by focusing. In the other, entanglement distribution, an entanglement source is located either in a satellite (S1) or on the ground (S2), and entangled photons are distributed to widely separated ground stations, where they’re tested for quantum-secure communication.
Taking all of these sources of loss (and a few others) into account, Goswami and Dhara numerically simulated how such a chain of relay satellite lenses might work in transmitting quantum information under two scenarios. One is so-called entanglement distribution, the protocol demonstrated by researchers in China on the Micius satellite, in which photons are entangled in space and sent in different directions via the satellite lenses, ultimately to be transmitted down to widely separated stations on Earth and tested for quantum security.
The other is a simpler “qubit transmission” protocol, in which quantum bits (qubits) are simply sent from a ground station to the first satellite, transmitted across the chain and finally beamed down to a second, distant ground station. Such a system would require a different kind of optical design, to counteract the impact of turbulence on the satellite uplink. Goswami and Dhara think this approach may have certain advantages, however, as it keeps both the qubit source and detection in more controllable, better-outfitted ground stations.
Under both scenarios, the team found that the total signal loss across 20,000 km would come in at around 30 dB. That’s comparable to the loss experienced across only 200 km of a direct optical-fiber link (assuming a loss rate of 0.15 dB/km in the fiber). “Such a low-loss satellite-based optical-relay protocol,” Goswami and Dhara write, “would enable robust, multimode global quantum communication and would not require either quantum memories or repeater protocol.”
“What this proposal basically does,” Goswami observed in an email to OPN, “is that it shifts the task of creating quantum network from physics to engineering.” He added, however, that some of the engineering likely wouldn’t be trivial, particularly with respect to designing and developing the satellites in the fleet. Still, he and Dhara stress in the paper that recent developments in space technology—embodied in reusable launch vehicles from organizations such as SpaceX and the vast constellations of classical-communications satellites being lofted into LEO by a number of private companies—make a system such as their ASQN considerably more feasible than it would have been in the past. Goswami and Dhara stress that recent developments in space technology make a system such as their ASQN considerably more feasible than it would have been in the past.
Goswami and Dhara believe that, by dispensing with the need for quantum repeaters or memory, the scheme they’ve proposed and modeled could open a range of possibilities implicit in a quantum network. Such prospects include secure communication via quantum key distribution, the linking of quantum computers, and precision long-distance quantum sensing.
The researchers admit, however, that a more complex network—that is, the long-term vision of a “quantum internet” now being fleshed out in a variety of research labs—would still require some sort of quantum memory to ensure completely lossless transmission.
This research could pave the way for the development of globally secure quantum communications networks, as the use of satellites would provide a high level of security against hacking and eavesdropping. The proposed system still needs further development and testing, but it presents a promising solution for enabling long-distance quantum communication without the need for repeaters.

Fiber Connect 2023: Telcos vs Cablecos; fiber symmetric speeds vs. DOCSIS 4.0?
Derek Kelly, Lumos’ VP of market development, went as far as to say that “fiber is always the answer,” and suggested cable alternatives will not stand the test of time. Kelly claimed that as $42.5 billion is set to roll out through the Broadband, Equity, Access, and Deployment (BEAD) program, relying on investments in fiber will provide stability over the next 15 years.
“I think we’ve all seen DSL and fixed wireless projects get funded over the last couple of years. And then what happens? Those areas ultimately become blocked from future funding until the definitions change. And then they become available for another grant. And we see public dollars going on top of previous public dollars.” Kelly said. He noted Lumos defines “unserved being no cable, underserved means they’re stuck with cable. And then there’s everyone else that has life-changing fiber. So we don’t care about speeds at this point.”
While acknowledging the need for funding in areas without even cable access, he noted another large-scale program after the BEAD initiative is unlikely. “Cable modems aren’t going to keep up with these definitions forever. Their lobbyists aren’t going to be able to convince people forever just make sure that they just barely can meet the definition of unserved,” he said. “We have communities that don’t have access to fiber. The FCC and NTIA may consider them as served today. And I agree the funding should go to areas that don’t even have cable yet, but the time is coming, where cable is going to be what’s unserved or underserved.”
Fiber execs mostly targeted cable’s “Achilles heel,” which is its lacking symmetric speed capabilities (upstream and downstream).
AT&T Fiber’s EVP Chris Sambar told a large keynote audience, “Don’t ask cable about symmetrical speeds, they don’t even know what that means.” In an earlier blog post, he wrote, “Fiber is superior technology for things like uploading large files and increased bandwidth. It delivers an amazing experience, with multi-gig speeds and equally fast up- and downlinks. It’s also critical for powering technologies like 5G (backhaul) and edge computing (fiber access for ultra low latency). And with a far superior upgradeable capacity to handle soaring demand for high-quality bandwidth well into the future.”
However, Jay Lee, CTO of ATX Networks said that cable operators are “right in the throes” of upgrading their networks to get to full DOCSIS 3.1, and that high-split type of architecture will allow them to achieve competitive speeds in the upstream. “Their downstream is probably two gigabits per second now and there’s a line of sight to be more than that,” he said. “Is it 10 Gig PON? No. But it’s still in that gig threshold that I think is as important from a consumer standpoint,” he added.
The next plan phase for cable is to move up to DOCSIS 4.0, which starts to get toward multi-gigabit upstream and five-plus in the downstream, sometimes upwards of 10 in the downstream. Lee noted that plenty of cable companies are doing “lots” of their own fiber buildouts. “Some of the statements made on cable were like ‘they can’t do anything about it’ and certainly they can. DOCSIS 3.1 high-split is just the start.”
Jeff Heynen, VP at Dell’Oro Group echoed Lee’s comments, noting that current DOCSIS 3.1 mid-split can deliver 2 Gbps downstream and up to 200 Mbps upstream, which is what Comcast is offering today. Charter and Cox’s high-split offerings can go even further, delivering 2 Gbps downstream and up to 1 Gbps upstream.
A recent interoperability test conducted by Cable Labs showed that DOCSIS 4.0 modems paired with CCAP and vCMTS platforms in high-split configurations could deliver up to 8.6 Gbps downstream and 1.5 Gbps upstream. Cable operators have claimed DOCSIS 4.0 modems should become available later this year, with volumes in 2024. Those downstream speeds would give cable “very comparable service tiers to most fiber providers,” Heynen said. “And this is before the outside plant is upgraded to DOCSIS 4.0, which will be capable of delivering up to 10 Gbps down and 6 Gbps up.” However, other analysts have hinted that DOCSIS 4.0 rollouts will take longer than cable companies are saying.

Huawei and Ericsson renew global patent cross-licensing agreement
The top two global RAN equipment makers, Huawei and Ericsson, have announced the renewal of a multi-year global patent cross-licensing agreement, which enables each to use the other’s standardized (3GPP, ITU, IEEE, and IETF standards for 3G, 4G, and 5G cellular technologies) and patented technologies. The patent sharing agreement includes network infrastructure, as well as endpoint devices.
“We are delighted to reach a long-term global cross-licensing agreement with Ericsson,” said Alan Fan, Head of Huawei’s Intellectual Property Department. “As major contributors of standard essential patents (SEPs) for mobile communication, the companies recognize the value of each other’s intellectual property, and this agreement creates a stronger patent environment. It demonstrates the commitment both parties have forged that intellectual property should be properly respected and protected.”
“Both companies are major contributors to mobile communication standards and recognize the value of each other’s intellectual property. This agreement demonstrates the commitment of both parties that intellectual property should be respected and rewarded, and that leading technological innovations should be shared across the industry. A balanced approach to licensing ensures that the interests of both patent holders and implementers are served fairly, driving healthy, sustainable industry development for the benefit of consumers and enterprises everywhere.”
Over the past 20 years, Huawei has been a major contributor to mainstream ICT standards, including those for cellular, Wi-Fi, and multimedia codecs. In 2022, Huawei topped the European Patent Office’s applicant ranking for number of patent applications filed, with 4,505 applications.
“Our commitment to sharing leading technological innovations will drive healthy, sustainable industry development and provide consumers with more robust products and services,” added Fan.
Huawei is both a holder and implementer of SEPs and seeks to take a balanced approach to licensing. Through the signing of this agreement, it is both giving and receiving access to key technologies. Fan said, “This agreement is the result of intensive discussions that ensured the interests of both patent holders and implementers are served fairly.”
Christina Petersson, Ericsson’s chief IP officer said, “This agreement demonstrates the commitment of both parties that intellectual property should be respected and rewarded, and that leading technological innovations should be shared across the industry. A balanced approach to licensing ensures that the interests of both patent holders and implementers are served fairly.”
The last time the two companies extended a cross-licensing agreement was in 2016. Over the past few years, both companies have actively contributed to developing key mobile standards.
Earlier this year, the European Patent Office published the EPO Patent Index 2022: with 4,505 patents filed, Huawei was the top contributor, while Ericsson came in fifth with 1,827. Currently, according to the Financial Times, Huawei owns 20% of global patents which makes it the world’s largest 5G patent owner. Ericsson says they’ve been granted 60,000 patents.
Both Huawei and Ericsson are part of the Avanci patent pool, although the Chinese company is a recent addition following Avanci’s launch of a 5G vehicular programme earlier this month, which it says will “simplify the licensing of the cellular technologies used in next generation connected vehicles.”
Other Avanci patent licencees include Samsung, Philips, Panasonic and ZTE.
However, while Huawei and Ericsson have not engaged in active patent litigation, towards the end of last year Huawei demonstrated an intention to be more litigious over its patent portfolio. This included filing lawsuits against car manufacturer Stellantis over mobile phone patents, as well as launching a series of lawsuits over Wi-Fi 6 patents against Amazon, Netgear and AVM.
Around the same time, in the midst of a US FRAND trial, Ericsson and Apple signed a global patent licence agreement. This ended one of the largest disputes over implementation patents and SEPs in recent years, which spanned the US, Germany, the Netherlands, Belgium, the UK, Colombia and Brazil.

T-Mobile US at “a pivotal crossroads” CEO says; 5,000 employees laid off
T-Mobile US Chief Executive Mike Sievert says the company is at a “pivotal crossroads.” Sievert’s comments come in a letter to staff in which he says the company is laying off 5,000 employees, or some 7% of the company.
T-Mobile CEO Mike Sievert argued the new job cuts would better position T-Mobile for the future. Sievert also cited increasing customer acquisition and retention costs. He described the layoffs as a “large change, and an unusual one for our company.”
Sievert wrote in a letter to T-Mobile employees:
“What it takes to attract and retain customers is materially more expensive than it was just a few quarters ago. We’ve been out-running this trend by accelerating merger synergies, and building our high-speed Internet business faster than expected, and out-performing in a few other areas. However, it is clear that doing everything we are doing and just doing it faster is not enough to deliver on these changing customer expectations going forward.
Today’s changes are all about getting us efficiently focused on a finite set of winning strategies, so that we can continue to out-pace our competitors and have the financial capability to deliver a differentiated network and customer experience to a continually growing customer base, while simultaneously meeting our obligations to our shareholders.”
T-Mobile CEO Mike Sievert (Source: UPI/Alamy Stock Photo)
T-Mobile’s layoffs will come over the next five weeks. Sievert wrote that the cuts would primarily affect corporate and back-office roles, along with some technology positions. These job cuts should come as no surprise. T-Mobile has been steadily reducing the number of its employees since it merged with Sprint in 2020. Earlier this year T-Mobile laid off an unspecified number of employees as it worked to overhaul its retail sales strategy. Can Sievert be trusted when he wrote, “After this process is complete, I do not envision any additional widespread company reductions again in the foreseeable future.”???
Telecom layoffs this year are surging. AT&T, Verizon, Crown Castle, Ericsson, Airspan, Cambium Networks, Cisco Systems and Dish Network are among telecom companies cutting jobs. Moreover, both AT&T and Verizon have recently embarked on new cost-cuttingprograms on top of previous cost reduction campaigns.
The layoffs come as T-Mobile and its rival cell carriers face increased competition from cable companies that are offering mobile plans and piggybacking on the carrier’s networks via MVNO relationships. Other MVNOs, or mobile virtual network operators, unrelated to the cable companies are also offering lower-priced cell plans.

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.

Dell’Oro: RAN market declines at very fast pace while Mobile Core Network returns to growth in Q2-2023
A new report from Dell’Oro Group says RAN sales declined at their fastest pace in nearly seven years during Q2-2023. According to preliminary findings from the market research firm, following the ‘intense ramp-up’ from 2017 through 2021. While RAN revenues stabilized in 2022 and 1Q23, market conditions worsened in the second quarter, resulting in RAN declining at the fastest pace in nearly seven years. The decline was not unexpected by Dell’Oro, yet the magnitude of the reversal was much steeper than anticipated.
………………………………………………………………………………………………………………………………..
The RAN market decline was surely expected by IEEE Techblog readers, as this publication has warned for years about the commercial failure of 5G mobile networks.
………………………………………………………………………………………………………………………………..
“It is tempting to point the finger at data traffic patterns, 5G monetization challenges, and the odds stacked against an economy struggling with persistent levels of elevated inflation,” said Stefan Pongratz, Vice President at Dell’Oro Group. “Although these are, of course, important factors, we attribute the poor performance in the quarter to the clouds forming in North America. Alongside challenging 5G comparisons, the decline was amplified by the extra inventory accumulated over the past couple of years to mitigate supply chain risks,” Pongratz added.
Additional highlights from the Q2-2023 RAN report:
- Top 5 RAN suppliers for 1H23 include Huawei, Ericsson, Nokia, ZTE, and Samsung.
- Nokia recorded the largest RAN revenue share gains between 2022 and 1H23.
- Huawei’s quarterly RAN share reached the highest level in three years. Huawei’s 2Q23 RAN revenue share outside of North America was as large as Ericsson and Nokia combined.
- Ericsson and Samsung’s RAN revenue shares declined between 2022 and 1H23.
- Regional projections are mostly unchanged; however, the short-term outlook has been revised upward in APAC excluding China and downward in the North American region.
- Global RAN revenues are expected to decline in 2023.
…………………………………………………………………………………………………………….
In a separate report, Dell’Oro says the Mobile Core Network (MCN) market returned to growth in 2Q 2023. The China region returned to growth and Europe, the Middle East, and Africa (EMEA) had the strongest quarterly growth rate since 3Q 2020.
“The MCN market shined on many fronts this quarter. The China region returned to growth with increased spending by two of the four Mobile Network Operators (MNOs). The EMEA region had its best quarterly growth rate since 2020, Huawei had record high revenues for the quarter, and Ericsson had its highest growth rate since 2Q20, as examples,” stated Dave Bolan, Research Director at Dell’Oro Group. “As a result, we are raising our outlook for 2023 year-over-year (Y/Y) growth rate from low single-digit percent to mid-single-digit percent.”
“As of 2Q 2023, we counted 44 Mobile Network Operators (MNOs) that have launched commercial 5G SA networks. One was added in 2Q 2023, Telefónica – Spain. The North America and EMEA regions of the 5G MCN segment Y/Y growth rates were in the triple-digit percent, signaling capacity additions to the 5G SA networks in both regions,” continued Bolan.
Editor’s Note: Despite years of promises, neither AT&T or Verizon has yet to deploy a 5G SA core network, without which no 3GPP defined 5G features/functions are possible.
…………………………………………………………………………………………………………………………
Additional highlights from the 2Q 2023 Mobile Core Network and Multi-Access Edge Computing Report include:
- The top MCN vendors worldwide for 2Q 2023 were Huawei, Ericsson, Nokia, and ZTE.
- The top 5G MCN vendors worldwide for 2Q 2023 were Huawei, Ericsson, ZTE, and Nokia.
- Five MNOs launched commercial 5G SA networks in 1H 2023.

VMware today is also introducing new and enhanced orchestration capabilities for the edge. VMware Edge Cloud Orchestrator (formerly VMware SASE Orchestrator) will provide unified management for VMware SASE and the VMware Edge Compute Stack—an industry-first offering to bridge the gap between edge networking and edge compute. Enhancements to the orchestrator will help customers plan, deploy, run, visualize, and manage their edge environments in a friction-free manner—allowing them to run edge-native applications focused on business outcomes. The VMware Edge Cloud Orchestrator (VECO) will deliver holistic edge management by providing a single console to manage edge compute infrastructure, networking, and security.
VMware defines the software-defined edge as a distributed digital Infrastructure that runs workloads across a number of locations, close to endpoints that are producing and consuming data. It extends to where the users and devices are—whether they are in the office, on the road or on the factory floor. Enterprises need solutions to connect these elements more securely and reliably to the larger enterprise network in a scalable manner. VMware Edge Cloud Orchestrator is key to enabling a software-defined edge approach. VMware’s approach to the software-defined edge features right-sized infrastructure (shrinking the stack to the smallest possible footprint); pull-based orchestration (security and administrative updates are “pulled” by the workload); and network programmability (defined by APIs and code).
“Audi wants to take factory automation to the next level and benefit from a scalable edge infrastructure at its factories worldwide,” said Jörg Spindler, Global Head of Manufacturing Engineering, Audi. “Audi’s Edge Cloud 4 Production will be the key component of this digital transformation, replacing individual PCs and hardware on the shop floor. Ultimately, it will increase factory uptime, agility, and the speed of rolling out new applications and tools across the production line. VMware Edge Compute Stack (ECS) and the VMware Edge Cloud Orchestrator (VECO) will offer a scalable way for Audi to operate a distributed edge infrastructure, manage resources more efficiently, and lower its operations costs.”
