What You'll Learn:

  • How does EMI differ from RMI?
  • What types of EMI and EMC affect medical devices?
  • Shielding options.
  • Dealing with computed-tomography interference.

The medical circumstance for many people requires that they have an implanted pacemaker/defibrillator or an implanted insulin pump. These kinds of critical equipment must not be disrupted by the operation of other electronics such as cell phones, etc.

What’s the Difference Between EMI and RFI?

The terms radio-frequency interference (RFI) and electromagnetic interference (EMI) often may be used interchangeably since radio waves are simply a subset of the electromagnetic spectrum. However, there’s actually a difference in practice.

EMI is usually characterized as any frequency of electrical noise; RFI is a specific subset of electrical noise within the EMI spectrum. RFI is classified as a disturbance that may affect an electrical circuit due to either electromagnetic conduction or electromagnetic radiation emitted from some external source.

IEC 60601-1-2 is the primary standard for EMI and electromagnetic compatibility (EMC) in electronic medical equipment and systems. This standard is created to define the safety and performance expectations for medical electronic equipment that is in the presence of an electromagnetic interference.

Medical Device Examples

There are so many types of medical devices that can be worn or implanted. Some of the main examples include:

  • Clothing
  • Watch
  • Ring
  • Shoes
  • Belt
  • Glasses
  • Armband

EMI/EMC Effects on Implanted or Wearable Electronics

Electromagnetic waves, which are emitted via communication devices (cell phones, etc.) or from an electrostatic discharge (ESD), will cause power disturbances that create a surge in conductive current as well as a localized radiated transient field.

EMI may occur when these three factors are present: a source of EMI, a coupling path and a receptor. The coupling path from the source to the receptor can be a magnetic field, electric current or even an electromagnetic field.

For instance, lightning is an EMI source that occurs in nature. Other sources of EMI might be radios, wireless networks, computers, cellphones or even any electric devices designed to transmit signals. Keep in mind that any signals less than 50 kHz will typically not be a cause of EMI concern (see figure).

Shielding Against EMI

Modern EMI shielding is more challenging than it has ever been before. The use and production of new medical devices, along with the construction of digital circuits that are smaller yet faster for these newer models, make them susceptible to electromagnetic fields and the inevitable interference. 

Gold is one of the best coatings that can be employed as an effective shield against EMI. Gold will not cause a reaction when it comes into contact with the human body, Thus, it’s a superior EMI coating for medical devices such as pacemakers. Occasionally, platinum also is used for shielding on pacemakers. Platinum will help resist corrosion, but cost is a problem since it’s higher than the already-expensive gold.

Multi-Cavity EMI Shielding

Designers of medical devices always need to consider EMI shielding to prevent medical equipment failure and stay compliant with federal regulations. One that front, the multi-cavity EMI shield will help solve various problems associated with shielding technologies. This method consists of a lightweight metallized plastic material that’s able to be molded to fit any design shape.

READ MORE: Pacemakers Study Confirms Cell Phone Interference

The metallized plastic material should be attached to the printed circuit board (PCB) after the surface-mount technology (SMT) reflow process. It will allow for easy component inspection or rework. The plastic material also can be easily removed by hand without damaging the board or the soldering. It has excellent shielding capability and is a very simple attachment mechanism as compared to perforated, soldered metal can shields.

Another option is a polymer-based, non-ferromagnetic shield, as it will not disturb MRI imaging.

EMI/EMC Filters

Employing an EMI filter may help with conducted emissions as well as meet immunity and fast transient requirements of radiated emissions. A power line or mains EMI filter can be installed at the power entry point of equipment to prevent electromagnetic noise from exiting or entering the medical implant/device. 

Computed-Tomography (CT) Interference with Medical Devices

The Federal Drug Administration (FDA) has been notified of a small number of reports of adverse events that may be associated with CT imaging of implantable and wearable electronic devices (such as insulin pumps, cardiac implantable electronic devices and neurostimulators).

A CT scanner will directly irradiate the circuitry of certain devices (when the device is visible in the resulting CT image) and may cause sufficient electronic interference to affect their function and operation. Although there’s a low probability of causing clinically significant adverse events, it’s still possible.

Interference can be avoided when the medical device isn’t within the primary X-ray beam of the CT scanner. CT is the preferred tomographic imaging technology for patients with implantable or wearable medical devices. CT is safer for patients with devices of unknown magnetic-resonance-imaging (MRI) safety status, too.

Summary

The rise of advanced wireless technologies creates an almost saturation of the spaces that surround us, along with a high level of EMI. This situation can have particularly negative effects on the latest array of worn and implanted medical devices, and it may present a danger to people using them.

Thus, designers need to “err on the side of caution” when designing worn and implanted medical devices. Methods of EMI shielding and filtering must be considered as a key part of these designs.

Killexams : Fiber Connect 2022: A Focus on Fiber Growth, Public-Private Partnerships and the Middle Mile

Public-Private Partnerships Require Work, Education

Public-private partnerships (P3s or PPP) continue to emerge as communities look for new ways to get broadband into the hands of more consumers and businesses.

Service providers are taking several approaches to establish P3s. Some of the most common are:

  • Build Operate Transfer (BOT): A local government has a private party build and operate the network for several years. The local government then takes over operations of the network.
  • Build Operate Own (BOO): A BOO is like a BOT arrangement, but the private entity is not required to transfer the project to the government.
  • Design-Build (DB): A government contracts with a private party to design and construct a project for a fee. The government retains ownership and may either operate it or contract out operations.
  • Buy Build Operate (BBO): This is a pre-existing network that is already complete and may have been operated by the government for some time. It is then transferred to a private party that takes it over entirely. An interim partner may need to invest in rehabilitating or expanding the project.

These agreements between ISPs and communities are gaining momentum as new federal broadband funding becomes available. States and local communities must consider partnerships with local service providers.

For example, the Broadband Equity, Access, and Deployment (BEAD) Program provides $42.5 billion to expand high-speed internet access by funding planning, infrastructure deployment, and adoption programs.

BEAD has three main priorities: unserved locations (no access to 25/3 Mbps); underserved locations (no access to 100/20 Mbps); and community anchor institutions (without gigabit connections).

Overcoming Obstacles, Challenges

Although using P3s can help make the most of federal and state broadband funding sources, panelists on the “Best Practices for Success with PPP” panel cautioned that public-private partnerships should be done carefully.

Scott Woods, vice president of community engagement and strategic partnerships at Ready.net, said there’s always a hurdle when a provider and a community establish a public-private partnership. “A public-private partnership is not as easy as it sounds,” he said. “They don’t magically occur. It takes a lot of work to educate.”

In Virginia, Lumos Networks/NorthState, which just completed its Alleghany Highlands project in November, will bring fiber-based broadband to 12,000 addresses and add more than 650 route miles of fiber within the Alleghany Highlands. Botetourt County and Lumos received funding for universal broadband coverage for homes and businesses from the Virginia Telecommunications Initiative (VATI) grant from the Commonwealth of Virginia.

Lumos is also making progress in Orange County, North Carolina, which issued a broadband RFP. NorthState currently serves the area.

“When we began digging into the design, there were about 7,000 homes that were unserved,” said Derek Kelly, senior director of market development for Lumos/NorthState. “We said every other home in [the] county has been suffering with cable and DSL.”

He added, “we were not only interested in [the area’s] unserved consumers, but also the underserved.”

Windstream, like Lumos and Ready.net, is also keen on pursuing public-private partnerships to enhance its broadband reach where it could not before.

For example, in 2021, the telco announced that it would expand the number of customer locations in its Pennsylvania service area that qualify for fiber-backed, symmetrical, 1-gigabit broadband service.

“We have been going to counties to find out how they are using their ARPA funds and if they could do a project with us,” said Trent Fellers, vice president and head of state government affairs for Windstream. “We then try to educate the community and ourselves on what it would take to develop a partnership in addition to looking at state grants and digesting the BEAD Program.”

Besides working directly with communities, Windstream works with other P3 partners, such as electric cooperatives. Previously, the telco established a partnership with Colquitt Electric Membership Corp. Windstream and Colquitt EMC will share responsibility for expanding a fiber broadband network that will reach some of Georgia’s most rural areas. “Colquitt helped build the fiber, and we used its labor to enhance that network,” Fellers said. He added, “We’re open to other P3 models.”  

Focus on Local Communications

As providers pursue P3 arrangements, the focus should be on what a provider and a community can bring to a deal. This comes down to understanding a community’s broadband needs and local regulations.

“Because there are a lot of different models out there, it’s important to figure out what both sides bring to the table and to have an open dialogue to see if it’s possible to make something work,” Fellers said.

Lumos uses a similar process when it pursues community broadband partnerships.

“There’s not a one-model-fits-all,” when it comes to building public-private partnerships, Kelly said. “It all comes down to how you can build things faster and cheaper.”

Establishing an agreement also depends on understanding how each state and town works. In North Carolina, many municipalities cannot issue grant dollars themselves because there may be a cable company serving that area.

“These agreements depend on every state and area by area,” Kelly said. “One thing a community can do to make a project faster and cheaper is control costs with streamlined permitting.”

In addition, a provider must take on the responsibility to understand the unique elements of a community. “The more information a community can come to the table with, the easier it is for the provider to work with it to structure a plan that works,” Woods said. “Many times, we have good anecdotal data, but we don’t have empirical data about where broadband is and where broadband is not.”

A community should also provide information about existing assets, local businesses and schools by conducting a feasibility study before approaching a provider to engage in a broadband partnership.

“You have to know where the assets are and what local businesses and the education community needs,” Woods said. “All that information will then be fed into what a provider partner will use to design and build.”  


AT&T Sets Organic, Community Partner FTTH Build Approach

AT&T has set an aggressive fiber-to-the-home (FTTH) build schedule to extend services to new markets and enhance speed tiers. During the first quarter of 2022, the service provider reported that fiber broadband generated $1.1 billion in revenue for its consumer segment, up 6.2 percent quarter-over-quarter.

AT&T also gained 289,000 fiber broadband subscribers and lost 284,000 nonfiber broadband subscribers. This represented a 21 percent gain in fiber broadband subscriber count compared with AT&T’s 5.19 million fiber broadband subscribers as of the first quarter of 2021.

The telco is not resting on its laurels. AT&T has plans to build fiber to 30 million premises by 2025. Specifically, this coverage includes more than 25 million consumer locations, 4 million small businesses, and 1 million enterprise locations.

“We have been building fiber in earnest for several years and now serve 17 million customer locations,” said Chris Altomari, vice president of broadband network product management for AT&T, in an interview with Broadband Communities during the Fiber Connect 2022 show in Nashville. “We will be building at scale for the next several years.”

Focus on Multi-Gig Speeds

As it ramps up FTTH coverage, AT&T is enhancing its speed tiers. After an initial launch in January, AT&T began offering up to 5 Gbps across parts of its entire footprint of more than 100 metro areas.

As part of those expansion efforts, the telco will bring AT&T Fiber and its Hyper-Gig speeds to seven all-new fiber metro areas in Texas, Oklahoma and Ohio by the end of the year.

Altomari said the speed increases reflect the growing demand for higher speed bandwidth. “It was time to introduce the 2 Gbps and 5 Gbps speeds given what happened during and after the pandemic with remote work and remote schooling,” he said. “Many of these high-bandwidth activities are here to stay.”

Although it is still early, Altomari said that AT&T sees “some nice take rates both from our existing customer base that is on lower speeds and also new customers coming into AT&T.”

AT&T is also keeping a close eye on growing broadband data consumption. “Today, the average consumer on the network is consuming around 400 Mbps of data per month, which is about 15 to 20 connected devices in a household,” Altomari said. “The upper-quartile customer is consuming a lot more than that.”

Though these even higher gigabit speeds aren’t neccessary today, AT&T wants to be prepared.

An early adopter of XGS-PON, AT&T held its first multi-gig trial in North Carolina in late 2021, with a wider, multi-gig customer launch in 2022 featuring 2 Gbps and 5 Gbps symmetrical broadband services.

In June, AT&T conducted a trial of 25GS-PON technology to demonstrate how to develop 20 Gbps speeds and beyond FTTH services out of a central office in Austin, Texas. “Our 25 Gbps trial shows the production capability of our fiber network,” Altomari said. “We think 2 and 5 Gbps speeds are adequate for now, but with fiber, you can update the equipment on both ends of the fiber to keep climbing up the gigabit stack.”

Neck-Deep in P3s

To complement its FTTH investments, AT&T has entered public-private partnerships in various communities. The telco recently announced agreements with Boonville, Indiana, and Amarillo, Texas.

AT&T finalized a $4.4 million contract in Boonville to build its fiber network to more than 4,000 locations throughout the city. Amarillo announced a $24 million project with AT&T to build its fiber network to more than 22,000 customer locations throughout the city.

“We’re neck-deep in public-private partnerships,” Altomari said. “Communities are leveraging American Rescue Plan Act funds, which is now known as BEAD.”

AT&T is excited to find ways to work with communities on leveraging new broadband funding sources, but the telco admits it’s not an easy process. The federal government has mandated that states use the funds to initially focus on bringing broadband to unserved and underserved areas that can’t get 100/20 Mbps.

“While it’s exciting and opportunistic to see all the federal funding flooding into this space to build fiber broadband in the next five to seven years, it’s equally complicated,” Altomari said. “It is challenging not only to get the funding at the state and local level but to square off with the right folks to understand their priorities and processes.”

Regardless, AT&T sees an opportunity to engage with several communities in its territories. “Our interest is to do as many partnerships as we can across our entire footprint to bring fiber broadband to those underserved areas,” Altomari said. “It’s a generational moment, but we’re seeing a lot of complexity.”

The BEAD funding will be released by the first half of next year. When that happens, Altomari expects it will spur an “intense squaring off with states on how those funds will be released and how they will be awarded.”

He added that because these awards require a 25 percent capital matching requirement, “the capital intensity for AT&T is going to be significant to win those awards and compete for those infrastructure builds.”


Middle Mile Presents New Opportunities for Providers, Vendors

Though there has been a continual emphasis on enhancing last-mile broadband networks, middle-mile networks are gaining attention on two fronts: new federal grant programs and networks that require backhaul and connectivity to internet access data centers.

The middle-mile network is the intermediary between an ISP and the high-speed internet. Local networks can ensure reliable, high-speed internet service for even the most remote communities by connecting to major networks.

Several states, including California, Massachusetts and northwest Colorado, have created middle-mile programs.

The National Telecommunications and Information Administration (NTIA) created the Enabling Middle Mile Broadband Infrastructure Program, which funds this vital part of the U.S.’s high-speed network. The program’s $1 billion in funding will reduce the cost of bringing high-speed internet to unserved and underserved communities.

Electric Co-ops, Vendors Get Active

During the “Middle Mile Innovation” panel at Fiber Connect 2022, panelists found plenty of growing interest in middle-mile networks.

Cisco, which has long been a provider of routers and optical equipment, is seeing new opportunities. “We’re seeing a lot of private-equity interest in the middle mile,” said Robin Olds, business development manager at Cisco. “Private equity is looking to invest and offering equity to build it out.”

In addition to private-equity firms funding middle-mile networks, a growing number of rural-based telcos and electric cooperatives are active. Seven States Power Corporation is building a 3,700-mile middle-mile fiber network interconnecting local power companies (LPCs) across the Tennessee Valley. Seven States recently announced that the project is on track and moving toward the launch of its second phase.

According to Seven States, the middle-mile network will enable electric grid modernization and facilitate broadband services deployments to unserved and underserved communities. The network is being built for two purposes: connecting power companies and enabling broadband services deployments.

“We’re in the design phase right now,” said Clint Wilson, senior vice president of engineering and market innovation for Seven States. “About next year, we’ll enter the construction phase.”

Similarly, Central Rural Electric Cooperative, an electric distribution cooperative that serves more than 20,000 meters in seven central Oklahoma counties, is getting involved in the middle mile. The cooperative has created Centranet, a wholly owned subsidiary of Central that will build a new FTTH network.

“The good news is that most electric cooperatives can extend the last-mile network to create a larger agreement,” said Sachin Gupta, director of business development for the Central Rural Electric Cooperative.

In Arkansas, the newly announced Diamond State Networks, a new middle-mile wholesale broadband provider, unites member cooperatives’ fiber networks throughout the state. “Two of the electric cooperatives on the Diamond State network in Arkansas are members of Oklahoma’s Broadband Coalition,” Gupta said.

Cisco is seeing new opportunities in right-sizing its router and optical switching gear for the rural market. “We’re trying to change the economics of the internet, whether it be a telco, cable operator, WISP, or electric cooperative,” Olds said. “We’re taking the same type of solutions that we provide to a Tier-1 operator and commoditizing down with our software and bringing them to a Tier-3 or Tier-4 telco or electric co-op to reduce the cost.”

In addition, Cisco has invested $20 million to develop its Rural Broadband Innovation Center. The facility was coordinated and funded through the Cisco Country Digital Acceleration (CDA) Program and is one of more than 1,000 active or completed projects in 40 countries that encourage innovation.

A rural provider can come to the center and look at the ways various solutions work together in a lab environment that emulates the behavior and requirements of a real-world network.

“We can bring customers, partners and consultants in to show them what we’re doing around our solutions and bring in last-mile technologies that may not exist yet,” Olds said. “We can show how last-mile technologies can interoperate with anything from fixed wireless to PON.”

Managing Supply Chain, Physical Issues

As service providers and electric cooperatives move forward with their middle-mile plans, the reality of dealing with supply chain issues continues to loom large, even for companies as large as Cisco.

“We believe that [the supply chain] will free up soon,” said Olds. “It’s a critical issue for all our customers.”

Given the deadlines the U.S. government has put on providers to get funding, Cisco has joined other vendors to advocate for its customers on the supply chain issue. “We have even gone as far as partnering with other manufacturers to provide a letter to the government to make it aware of all the challenges we have right now,” Olds said.

But the supply chain is just one issue. For Seven States, getting funding together is even more difficult. It has developed a plan to share resources with 153 local power companies.

“Funding is an issue,” Wilson said. “We’re addressing that by sharing the risk between Seven States and the local power companies, which will build and own the fiber infrastructure.”

Seven States is also dealing with physical land issues. “We’re building out this network, and we have two areas that cross a national forest,” Wilson said. “There are no power lines in these areas, so we’ll have to be creative and work through a couple of options for that.”


Product Showcase

During the Fiber Connect show, several vendors highlighted new products. Here is a summary of some new innovations.

Render Expands Construction, Maintenance Platform

As the broadband industry prepares to support more than 10 million FTTH connections by 2023, not all activity is related to large, one-time fiber deployments. Increasingly, network operators and construction contractors are looking to solve adjacent construction challenges with the same field productivity and downstream efficiencies. To accommodate these issues, Render has expanded its Network Construction Platform to include three solutions: Render Scale, Render Connect and Render Redline – designed to reduce the time and effort required to manage all sizes and types of network builds.

The platform’s new capabilities can streamline construction beyond large-scale deployment, including stand-alone GIS redline changes, small or high-volume network maintenance works, and customer drops:

Render Scale: A geospatial construction solution for managing large-scale deployment. Render’s Digital Construction Blueprint transforms network designs into a task-level GIS scope, harnessing the power of automation and machine learning to achieve industry-leading outcomes.

Render Connect: This platform helps manage small or high-volume builds with highly efficient digital construction processes and protect margins with faster scoping and turnover of assets for customer connections and ongoing operations and maintenance work.

Render Redline: As a light-touch redline change solution, it helps construction teams simplify their redline change process with real-time GIS data capture and management.

OFS Unveils Sherpa ADSS Cable Management System

Offering a reduction in fiber network installation times and costs for municipalities and electric co-ops, OFS introduced its Sherpa ADSS (all-electric, self-supporting) Cable Management System. Sherpa is a patent-pending, dielectric system enabling the attachment of drop cables to ADSS trunk cables or ADSS trunk cables to electrical neutrals. As fiber network builders expand in rural areas and municipalities around the country, many have selected ADSS cable as the primary deployment method because of its reliability and speed of installation. Until this point, ADSS cables have not been used to manage drop cables. A different version of the Sherpa system can be used to attach ADSS cables to electrical neutrals in areas where maintaining ground clearance can be a challenge.

According to a new study, one in 20 people who have contracted Covid-19 display long-term smell or taste problems. The findings comes as the NHS announced plans to Boost long Covid-19 services for people suffering ongoing illness after infection.

The after-effects can cause "severe distress", academics said as they called on health systems around the world to be prepared to support people when dismissed by clinicians. They said daily activities such as smelling coffee and testing the flavour of food can become “disgusting and emotionally distressing”.

The study could mean that millions around the globe may have suffered or be suffering smell and taste issues at least six months after the initial infection. Under new guidelines, patients with suspected long Covid-19 in England will have an initial assessment within six weeks.

Meanwhile, the new study, published in The BMJ, reviewed data from 18 studies involving 3,699 patients. Based on the data, the team of international researchers, including some from the UK, used modelling to estimate how many people go on to suffer from altered taste or smell for at least six months after a Covid-19 infection.

They concluded that an estimated 5.6 per cent of Covid-19 patients suffer smell dysfunction for at least six months and 4.4 per cent have an altered taste. In July there had been some 550 million infections worldwide, which means 15 million may have had lasting smell problems and 12 million patients had taste problems for at least six months, the authors estimated.

Women were less likely to recover their sense of smell and taste, they found. And patients who suffered the most at the initial infection were also more likely to have lasting effects.

In a linked editorial, a team of Italian academics wrote: “About 5 per cent of people report smell and taste dysfunction six months after Covid-19, and given that an estimated 550 million cases of Covid-19 have been reported worldwide as of July 2022, large numbers of patients will be seeking care for these disabling morbidities. Health systems should, therefore, be ready to provide support to these patients who often report feeling isolated when their symptoms are overlooked by clinicians.”

They said people “only realise the importance of smell when it is lost” and they can be “severely distressed” when they lose these senses. “Loss of smell and taste adversely affects quality of life by depriving those affected of several everyday pleasures and social bonds,” the team, led by Paolo Boscolo-Rizzo from the University of Trieste, wrote.

“People can also experience anorexia, food aversions, malnutrition, anxiety, and depression,” they added. They highlighted that parosmia – the experience of a distorted sense of smell – means that for many this “transforms a pleasant odour into an unpleasant one”. This means that “daily activities such as smelling coffee and sensing the flavour of food can become disgusting and emotionally distressing”.

Meanwhile, NHS England has set out its Long Covid Action Plan for thousands of people with ongoing symptoms. Under the plans, people will be able to access services closer to home and be given an initial assessment within six weeks at a specialist clinic.

It is hoped that the £90 million service will reduce the need for a patient to return to their GP for multiple different symptoms. The money will be used to fund 90 specialist long Covid-19 clinics, 14 hubs for children and young people and investment in training and guidance to support GP teams in managing the condition.

Dr Kiren Collison, GP and chair of the NHS long Covid taskforce said: “Long Covid can be devastating for those living with it, and while we continue to learn more about this new condition, it’s important people know they’re not alone, and that the NHS is here for them. In just under two years, the NHS has invested £224 million to support people experiencing long term effects from Covid-19 – from setting up specialist clinics, hubs for children, and an online recovery platform, to providing training for GP teams.

“Today’s plan builds on this world-leading care, to ensure support is there for everyone who needs it, and that patients requiring specialist support can access care in a timely and more convenient way.”

Meanwhile, a separate study has concluded that face shields do not provide high-level Covid-19 protection. Some use the shields as a method of protecting themselves from the virus when they are unable to use masks.

But a new study from academics at the University of East Anglia assessed the 13 styles of face shield in a laboratory setting. Researchers found that while all the face shields provided some protection, none gave high levels of protection against “external droplets contamination”, according to the study, published in the journal, American Journal of Infection Control.
