US healthcare providers tap Verizon for neutral host, private 5G combo nets | Computer Weekly

US healthcare providers AdventHealth and Tampa General Hospital (TGH) have signed deals with Verizon Business for neutral host or combination neutral host and private 5G networks.
AdventHealth is a non-profit medical organisation headquartered in Altamonte Springs, Florida, that operates facilities in 10 states across the US, offering a range of services, including primary care, specialty care, urgent care, imaging, rehabilitation and home health. It employs more than 100,000 caregivers in physician practices, hospitals, outpatient clinics, skilled nursing facilities, home health agencies and hospice centres.
Tampa General Hospital is a 1,040-bed non-profit hospital, tertiary, research and academic medical centre located on Davis Island in Tampa, Florida, servicing western Florida and the greater Tampa Bay region. TGH is said to be one of the region’s only university-level academic medical centres, and is licensed for 982 beds, with approximately 15,000 team members and providers.
Verizon Business says healthcare CIOs and business decision-makers are currently facing a surge in operational complexity at their facilities. It added that the growth of electronic patient records, specialised connected equipment and telehealth has led to an explosion of healthcare data, which can create bottlenecks that slow down clinicians and administrators if not met with appropriate networking capability.
Simultaneously, it observed that healthcare campuses are evolving to accommodate multiple network user groups with varied needs – for example, patients and visitors requiring reliable connectivity while on site, staff conducting increasingly digitised operational work, and care providers and technical experts using specialised equipment with heightened security and bandwidth requirements.
In short, the operator regards healthcare environments as ideal settings for flexible, onsite data networks. They must accommodate hundreds, if not thousands, of devices at a time, serve users of varying data requirements, and accommodate technologies that serve public, private and highly specialised application sets, both for day-to-day operations and future-facing initiatives.
To meet these challenges, the company believes the combination of neutral host and private 5G networks helps manage increasingly complex data needs for varied user groups at its facilities – for example, neutral host for patients, visitors and other public-network users, and private 5G for mission critical operations.
Moreover, the operator sees the network combination as helping to cover evolving connectivity needs for diverse device sets, user groups and data capabilities. These include connected hospital equipment for care provision; administrative and office equipment for operation and personal devices for general use; and the creation of user groups such as doctors, nurses and care providers, as well as executives, administrators, research experts, patients, visitors, and onsite staff.
Verizon Business said neutral host and private 5G networks combined can support a growing density of connected devices with varying security, bandwidth and capability requirements for diverse user groups, as well as offer flexible connectivity for business continuity and future-proofing for facility expansions and transformations.
The Neutral Host Network component is said to be able to allow the general public to automatically achieve a strengthened mobile signal on a specific premises via dedicated network infrastructure onsite. Receiving a strengthened signal requires no special action on the part of the visitor; the campus becomes just like any public setting with ideal cellular reception.
In parallel, to support critical care-delivery services and sensitive data workflows for the hospital, facilities can deploy secure, high-bandwidth and low-latency private 5G networks side-by-side with neutral host networks. In addition to enabling data-intensive, mission critical hospital operations, the private networks also serve as a platform for future-tech readiness and innovation, allowing the hospital administration to pilot applications and incorporate new connected devices and technology.
Ericsson is the platform provider to Verizon for the on-premise network buildouts.

Inspired by the EU: Sweden eyes open standard for encrypted chat services | Computer Weekly

Government departments in Sweden are considering deploying “open network” encrypted messaging services as an alternative to proprietary collaboration tools.
Some 40 of Sweden’s government agencies are collaborating on a project that could see them rolling out a secure messaging service across government departments.
The initiative comes as European governments are accelerating the deployment of “sovereign” technologies that allow them to be less reliant on “siloed” software from technology suppliers.
The trend has been given new impetus by the war in Ukraine and growing political upheaval in the US.
A membership organisation for government agencies interested in digital technology, eSam has proposed developing a government messaging service based on Matrix, an open network offering secure decentralised messaging.
Replacing emails and phone calls
Kenneth Edwall, a government employee and member of the eSam working group on the project, told Computer Weekly that one of the aims of the proposal is to make it possible for government departments to communicate more efficiently.
“We as agencies need to collaborate with each other,” he said. “Having email is not the best tool, and having phone calls is not a good method either.”
When eSam first began evaluating collaboration technology in 2021, government departments in Sweden had standardised on Skype for Business as a collaboration tool across government.
The tool was easy to use, and it was possible for government employees to collaborate with colleagues by searching on their email and initiating a chat.
They deployed Skype in a decentralised way, giving agencies the freedom to buy the service from suppliers or deploy it on their own datacentres.
This created a robust, decentralised network, said Edwall. “If you have 100 different deployments of Skype, it’s hard to target them all in a cyber attack,” he added.
Multiple messaging services
Since then, partly as a result of Microsoft phasing out Skype in favour of its Teams software, government departments have taken up a range of incompatible messaging apps. They include Rocket.chat, Teams, Zoom, open source platform Mattermost, video platform Jitsi Meet, and Element.
“We are now seeing at least five or six messaging tools being chosen by authorities today, and if it continues, we are going to have a big mess of fragmented systems,” said Edwall. “There is no open protocol that allows them to interoperate with each other.”
Imagine taking email and splitting it among five or six different email suppliers, each of which was incompatible with the other. “That is what we have today with messaging,” he added.
This means government employees in Sweden are having to learn several collaboration tools so that they communicate with people in other parts of government.
The security risks
The apps pose security risks as collaboration tools fall outside security safeguards, and when people leave their jobs, they may still be connected to government-focused chat groups.
In January this year, eSam began a review to look at how to solve these problems. One option was to do nothing and leave it to technology providers to develop interoperable messaging services, but it ruled that out.
“We don’t believe that the entire market wants to be interoperable,” said Edwall. “We believe that some of the larger vendors have an incentive not to be interoperable with other vendors.”
Another idea was for Swedish government departments to standardise on a propriety platform, such as Zoom or Microsoft teams. However, under Swedish law, government departments can not legally chose to buy technology from a favoured supplier. Each contract has to go out to tender.
Federated open source messaging
Eventually, eSam settled on an open-source federated messaging standard that allows government departments to build interoperable collaboration platforms, either in-house, or bought in from a provider.
“The key is we are not taking sides in regards to public cloud, private cloud or on premise,” said Edwall. “We are not taking sides on proprietary or open source solutions, but we want them all to have the same open protocol that allows them to interact with each other.”
The eSam members looked at a variety of options, including the Matrix protocol, Signal, XMPP and others, before deciding on Matrix.
“We had meetings with other public sector authorities in the EU [European Union] and we realised that most of the authorities we talked to were looking at the Matrix protocol,” he said. “Some of them were already in it and others were evaluating it.”
For eSam, Matrix offers a number of advantages. First, it is federated, which means the Matrix network relies on decentralised nodes. If one fails, or is hit by a cyber attack, messages can still re-route to the right destination.
Second, different government agencies can chose to deploy the technology in different ways. “You can also decide who you want to deploy our setup,” said Edwall. “You could use public cloud services or private on-premise services.”
European governments are using Matrix
Matrix is widely used by the public sector in France, Switzerland – where it has been championed by Swiss Post – and Germany. The European Commission and the Netherlands also have plans to roll out the technology.
The team has prepared a report that it will present to the eSam board in November.
Its recommendations are to build on open standards and protocols to ensure government agencies can avoid being locked into one supplier, and to give organisations the ability to choose how they want to deliver technology, either through public cloud, private cloud, on-premise systems or third-party suppliers.
If the plan is approved, the move to Matrix-based messaging is likely to take years – or even decades.
“We don’t want authorities to just throw out their current communication, because they might have a five or 10-year contract,” said Edwall.
“We want the market to shift so the vendors understand what they gain from using an open standard, similar to the open standards we use in email,” he added. “We want the market to understand that they should start adapting their products.”

New Report Finds Efforts to Slow Climate Change Are Working—Just Not Fast Enough

In the 10 years since the signing of the Paris Agreement, the backbone of international climate action, humanity has made impressive progress. Renewable energy is increasingly cheap and reliable, while electric vehicles are becoming better every year.
By virtually every key metric used to measure progress, though, we are still lagging behind where we would need to be to avert the worst effects of climate change, according to a report released Wednesday by a coalition of climate groups—and we’re running out of time to right the ship.
“All systems are flashing red,” Clea Shumer, a researcher at the World Resources Institute, one of the organizations involved in the report, said last week on a call with reporters. “There’s no doubt we are largely doing the right things—we are just not moving fast enough.”
The Paris Agreement aims to keep the world from warming more than 1.5 degrees Celsius above preindustrial levels by the end of this century. To measure progress toward this goal, the report looks at emissions from 45 different sectors of the global economy and environment, measuring everything from building electrification to use of coal in the power sector to global meat consumption.
Grimly, none of the indicators the report measures are where they need to be to keep the world on track to meet the goal of limiting warming to 1.5 degrees. Six of the 45 indicators are “off track”—progress is being made, but not fast enough—while almost 30 are “well off track,” meaning progress is much too slow. Five, meanwhile, are headed in the “wrong direction,” meaning the situation is getting worse, not better, and needs an urgent U-turn. (There’s not enough data, the report says, to measure the remaining five indicators, which include peatland degradation and restoration, food waste, and the share of new buildings that are zero-carbon.)
One of the most consistently off-track markers, experts said, was the global effort to phase out coal, one of the largest contributors of greenhouse gas emissions. While coal’s share in global electricity generation did go down slightly in 2024, total coal use actually hit a record high last year thanks to growing electricity demand, especially from China and India. A dirty power grid, Shumer said, has “huge knock-on effects” for other progress indicators like decarbonizing buildings and transportation.
To get on track, the world needs to increase its pace of coal phaseout tenfold, Shumer said. That, she continued, would entail shutting down more than 360 medium-sized coal plants each year and canceling every coal-fired power plant currently in the global development pipeline.
“We simply will not limit warming to 1.5 degrees if coal use keeps breaking records,” Shumer said.’

Samsung’s Galaxy XR Mixed Reality Headset Undercuts Apple’s Vision Pro by $1,700

It has been five years since Samsung and Google stopped supporting their respective mobile virtual reality headsets. For a second try, the companies have partnered up with a bolder vision in the mixed reality space, starting with the new Galaxy XR. Announced last year as Project Moohan, it’s the first headset powered by Android XR, a new platform for smart glasses and headsets built on Android and Google’s Gemini assistant from the ground up.
The Galaxy XR is available today in the US and South Korea for $1,800. (You can finance it for $149 per month for 12 months.) That’s a leap over standard VR headsets like the Meta Quest 3, but a significantly lower price than the $3,499 Vision Pro, which Apple is refreshing this week with the new M5 processor.

I was able to demo the headset again last week at a closed-doors media event in New York City held by Samsung, Google, and Qualcomm—the Galaxy XR is powered by Qualcomm’s Snapdragon XR2+ Gen 2 chip—but not much was different from my original hands-on experience last year, which you can read more about here. The official name and price were the two big question marks, but that has now been addressed.
The Galaxy XR purports to do nearly everything that Apple’s device does. Pop the headset on and you’ll be able to see the room you’re in through the pancake lenses and layer virtual content over it, or whisk yourself off to another world. Your hands are the input (controllers are available as a separate purchase), and it uses eye tracking to see what you want to select. You can access all your favorite apps from the Google Play Store; XR apps will have a “Made for XR” label.
Samsung’s headset is more plasticky and doesn’t feel as premium as Apple’s Vision Pro—I noticed the tethered battery pack on a demo unit looked well-worn with fingerprint smudges on the coating. But this general construction makes it feel significantly lighter to wear. I wasn’t able to try it for a long period, but it felt comfortable, with the only issue being a sweaty brow after a 25-minute bout with it on. The headset was warm at the top, but the battery pack remained relatively cool. Speaking of, the battery lasts 2 hours or 2.5 hours if you’re purely watching video. That’s on par with the original Vision Pro, though the M5 version extends it to 2.5 with mixed use.
