Preliminary investigation offers possible cause of Arecibo Observatory telescope collapseBy Meghan Bartels
An ongoing investigation of the December collapse of the iconic radio telescope at Arecibo Observatory in Puerto Rico offers early evidence that a manufacturing issue may have contributed to the failure. The telescope's massive science platform, which weighed in at 900 tons, was suspended above the vast radio dish by three dozen supporting cables. But in August 2020, one of those cables slipped out of its socket; before the failure could be repaired, a second cable snapped outright in November. The U.S. National Science Foundation (NSF), which owns the site, determined that the platform was too unstable to safely repair and decided to decommission the instrument. Before that could happen, the telescope collapsed on its own on Dec. 1. Engineers have been investigating the cables since August, and crews have been cleaning up the debris and monitoring environmental concerns since the collapse,observatory director Francisco Cordova said during a panel discussion held on Jan. 21. "The site cleanup and the debris removal really is ongoing," Cordova told the panel, which is focused on small solar system objects like asteroids in order to inform the National Academies committee that's putting together the document that will shape planetary science priorities for the next decade. "In general, I think that is moving in the right direction." Cordova noted that the telescope's azimuth arm, which helped steer its instruments, and the hanging dome suspended from it that held antennas and the facility's radar transmitter, have already been removed from the site. Environmental engineers have also collected two types of potentially hazardous materials that were used on the platform, he said. The next priority is to clear out remaining platform debris; to reach that material, work crews have deconstructed part of the massive Arecibo reflector dish, which measures 1,000 feet (305 meters) across. The observatory team is also evaluating how much of the dish itself can be rescued, Cordova said. "There's still a lot of discussions as to how much of the primary reflector can be saved and how do we go about that," Cordova said. "Our focus right now is the safe removal of the platform structure, and then we'll look at it from there." Simultaneously, two forensic investigations are evaluating what caused the telescope's collapse. One investigation focuses on the so-called auxiliary cables. These 12 cables were added in the 1990s, when the observatory installed the massive hanging dome that distinguishes the telescope's appearance in the movie "Contact" from its previous cameo in James Bond's "GoldenEye." The first cable to fail was one of these auxiliary cables, which slipped out of its socket where it connected to one of the three supporting towers surrounding the dish. "Preliminary investigation has revealed that there was a manufacturing error in those cables — in particular, the socketing procedure wasn't done appropriately, and that led to advanced degradation of that particular structural element," Cordova said. "But the final forensics investigation is still to be completed." A second forensic investigation focuses on the main cables, which are original to the telescope's construction in the early 1960s. It was one of these main cables that snapped in November, despite engineers' estimates that it was only carrying about 60% of the weight it should have been able to withstand. As they work, site engineers are separating debris that could be relevant to the two forensic examinations. In addition, Cordova said that personnel are evaluating debris being removed for potential historic importance so that items can be saved. Both the clean-up and investigation processes are ongoing, Cordova emphasized; in addition, the NSF is working separately on understanding the collapse and evaluating the site's future, including for a report that Congress has requested by late February. And the answer may never be crystal clear. "Certainly, there's typically not a single item that contributed but a multitude of items that contributed to the particular failure," Cordova said. In addition to the facility's age, the past few years have been hard on Puerto Rico. In 2017, Hurricane Maria battered the island, and over the course of 2020, it experienced more than 10,000 earthquakes. "Basically, we were shaking the entire time; that certainly could have been a factor," Cordova said. "That's being still analyzed by the engineering teams." |

How will UK hospitals let go of the pager?26 January 2021 (Last Updated January 26th, 2021 12:17) In many UK hospitals, pagers are still de rigueur when it comes to clinical communications. The devices only need to be charged once or twice a month, and hospitals buildings can be dead zones for mobile phone signals, so in a sense it’s not hard to see why. But in 2019, the NHS was urged to stop using pagers by 2021 and upgrade to more modern technology – so why has the tech had such a dominance over the British healthcare system for so long? Chloe Kent takes a closer look.
In February 2019, the UK’s NHS was told to stop using pagers by the end of 2021 in order to save money. At the time, the service still used approximately 130,000 pagers, roughly 10% of the total still in use globally. Not only was the technology considered to be archaic and outdated by many, but the devices were still costing the NHS about £6.6m per year. While progress has since been made in phasing out the devices, with a number of hospitals and healthcare centres adopting alternative communications technologies, developments haven’t gone as fast as it was hoped two years ago. Considering the impact of the Covid-19 pandemic on healthcare services, it’s unsurprising that phasing out the pager hasn’t been prioritised when thousands of lives have been at stake. But steps have still been taken in the right direction over the past year. NHSX, the government agency responsible for digitally transforming the UK health service, launched the Clinical Communications Procurement Framework in July. The service is designed to support NHS organisations in phasing out pagers, allowing them to either make a direct award to a new service provider or undertake a mini competition to select the provider best suited to their needs from an approved shortlist. But the framework is running until August 2022, with the potential to extend for another 12 months, far later than the initial December 2021 goal. What technologies could begin to replace the pager over the coming years – and why do they need to go in the first place? Pagers are old school, but mobile networks can have major reliability issuesOnly one national pager network still exists in the UK, Capita’s PageOne, after Vodafone axed its service in 2018. But the technology is far from obsolete just yet, and the way it works can actually make a lot of sense in a healthcare context. Pagers are one-way communication devices that can receive short messages but can’t send any reply. To send a message, hospital staff can call an automated phone line or speak to a dedicated operator and leave a message. The recipient’s pager will then beep and either display a message or – if there’s too much information to send via the paging system – show a phone number to call. If they need to correspond back, the recipient must find another way to communicate, such as via a mobile phone message or a landline phone inside the hospital. Refero medical director and clinical director Dr Ian Jackson says: “A doctor might be with a patient in the middle of a delicate procedure and unable to reply immediately, but they know they have been bleeped and that there is an issue. “The downside is that when you have a moment to ring back, often the person who actually answers doesn’t have a clue why you were bleeped.” While the inability to reply via pager can be a little arduous, pagers have several benefits over two-way communication systems. Mobile phones need regular recharging, for example, which isn’t a problem pagers face as their batteries can last for weeks. Hospitals can also be dead zones for mobile phones and WiFi signals. Many walls inside hospitals are built extra thick to stop X-rays from penetrating through, but these can block mobile and Internet signals as well. Pagers don’t have this problem, as they communicate through very high-frequency radio signals that aren’t blocked by thick walls. Mobile and WiFi networks are also known to interfere with hospital equipment, which doesn’t happen with pagers. Pager signals also more reliable than mobile signals, pinging off multiple satellites rather than just the nearest phone mast. This makes it almost guaranteed that messages will still come through, while web-based networks can experience slowdowns and unavailability that can lead to delayed messages or even stop them sending at all. If one paging satellite is down, others are usually working, but when a phone mast goes down there’s often no alternative until it’s fixed. Critical communications specialist ETELM international sales director Paul Ward says: “Mobile operators may be proud of their nationwide coverage outside, but inside can be a different matter. Hospitals are typically sprawling buildings, often including a mix of building materials and robust walls to create restricted or extra-secure areas. “In turn, this means that patchy coverage and dead zones are a reality in most healthcare settings, both in terms of mobile and WiFi networks. This means that relying solely on public networks to get healthcare practitioners to emergency scenarios within minutes could have major reliability issues.” The smartphone systems aiming to oust the pagerDespite the operational issues associated with replacing pagers with mobile devices, the new contenders arriving onto the healthcare communications market still maintain that the improved functionality of their systems make them ultimately superior to the pager. Alertive is a mobile app that has already been rolled out by a number of NHS Trusts, many reaching out via the Clinical Communications Procurement Framework. It still centres the critical alerting aspects of a pager but facilitates two-way communication by allowing recipients can respond to the emergency alerts with their ability and intention to attend incidences. It also features an intuitive clinical messaging platform where clinicians can discuss specific cases and is designed to be interoperable with most hospital systems. Plus, it is set up to failover to an SMS or email message if the in-app alert can’t go through. “Although we’re there to replace the technology with a superior way of doing things, there isn’t a massive transformational change to the ways that people operate and work required on day one of implementing our system,” says Alertive CEO Matt Gauler. “Our solution will still simply act like a pager solution.” Alcidion’s Smartpage system, which operates via 4G and WiFi networks, was also appointed to the Clinical Communications Procurement Framework earlier this year. Smartpage is designed to replace existing paging systems with a secure communication tool that has the same intuitive interface as a smartphone. The messages sent via the platform are integrated alongside patient records, vital sign data and early warning scores to catch any deterioration in a patient’s condition early. It also contains read receipts and instant two-way replies, with the intention of improving clinical collaboration, and allows for the sharing of images. Alcidion general manager Lynette Ousby says: “Senior clinicians have told us about the challenges of not having access to even the most basic information about why they are bleeped – sometimes requiring them to leave a patient’s bedside to respond and access that information. To be effective in their roles, clinicians need to be able to discuss patient care easily with any colleague, so technology that offers multi-person patient-centric communication is the obvious way forward. “Modern systems are now preferable to support secure messaging, manage tasks, share critical information and to help to provide systematic ways of managing regular activities such as handovers that are important to patient safety.” It’s clear that the pager falls short of systems like these when it comes to facilitating clear clinical communication – but they’re still reliant on technology like smartphones, tablets and laptops, which aren’t as practical in-clinic. Could the NHS pager be reformed instead of replaced?Many of the shortcomings of NHS pagers could be surpassed if they were able to send two-way messages – and by using Terrestrial Trunked Radio (TETRA) this could very well be made possible. “It is easy to assume that emergency scenarios demand the very latest, next-generation technology. But the reality can be a little more complex,” says Ward. “Traditional radio devices using communications networks such as TETRA can offer a more standalone approach to in-hospital communications, which does not risk disrupting other equipment. This, clearly, is particularly important during times of crisis.” TETRA have been around since 1995 and are in use by a number of emergency response teams globally. Motorola’s TETRA two-way pagers, for example, provide the Bavarian Federal Agency for Technical Relief with a device that can allow them to read and respond to messages on a two-inch colour display. Rather than replacing all of the pagers in the NHS with smartphones, an improved two-way paging system could be the answer. Of course, a TETRA pager is still a pager, and will lack the detailed conversational elements of platforms like Alertive and Alcidion. But the ability to send even limited replies back – indicating whether or not it’s possible to attend A&E, for example – could be a significant improvement to the day-to-day operations of hospital staff. Plus, the shortfalls associated with digital solutions, such as comparatively poor signal and battery performance, are bypassed entirely. “TETRA can actually be more reliable and offer more comprehensive coverage than their newer counterparts,” says Ward. “Reliable communications between medical practitioners in hospitals and healthcare settings are clearly absolutely critical – a matter of life and death. Doctors may need to be summoned within seconds in order to respond to an emergency scenario. The unfolding coronavirus pandemic has brought this into sharper focus than ever before.” |

GLENAYRE INFRASTRUCTUREI would like to recommend Easy Solutions for Support of all Glenayre Paging Equipment. This Texas company is owned and operated by Vaughan Bowden. I have known Vaughan for over 35 years. Without going into a long list of his experience and qualifications, let me just say that he was the V.P. of Engineering at PageNet which was—at that time—the largest paging company in the world. So Vaughan knows Paging. GTES is no longer offering support contracts. GTES was the original group from Vancouver that was setup to offer support to customers that wanted to continue with the legacy Glenayre support. Many U.S. customers chose not to use this service because of the price and the original requirement to upgrade to version 8.0 software (which required expensive hardware upgrades, etc.). Most contracts ended as of February 2018. If you are at all concerned about future support of Glenayre products, especially the “king of the hill” the GL3000 paging control terminal, I encourage you to talk to Vaughan about a service contract and please tell him about my recommendation.

Does the kind of cable really matter?HDMI and EthernetFor a long time I have scoffed at the ridiculous prices that some people pay for interconnect cables in their stereo equipment or their home theaters. (Some even use solid silver wire!) So I just went with, “any ol' cable or wire will do.” Except speaker cables. I believe bigger is better. Nothing very expensive or extremely big — just no. 8 (or sometimes a little smaller) stranded copper wire depending on the speaker in use. (Front Left, Center, and Right speakers get the largest.)
In CAT7 each of the 4 pairs are twisted and shielded. A second shield surrounds all 8 wires in the round version. The flat versions are suitable for short patch interconnects but the round versions should be used for longer runs through walls to routers and/or servers. The round ones have the extra outer shield, have larger internal wires, and are more durable. Of the many types of Ethernet cables, CAT1 to CAT5 are considered obsolete and CAT8 is brand new and a bit of an overkill. So CAT6 is very good — and CAT7 is the best choice for now (IMHO) — (and not much difference in price). We upgrade our equipment, and update our software, so why not upgrade our interconnect cables? A little technical knowledge is useful. It doesn't turn you into a nerd.

10-Year-Old Community Fiber Network Records $2.69 Billion in Benefits
Ten years ago, energy and connectivity company EPB built America’s first gig-speed community-wide network, establishing an advanced smart grid power distribution system in Chattanooga, TN, reported Smart Cities World. Recently, Rollins College of Business at the University of Tennessee at Chattanooga released independent research documenting the network’s benefits, to the tune of $2.69 billion. According to EPB President/CEO David Wade, “From education and innovation to job creation, it’s amazing to see how our customers are realizing possibilities we could only imagine 10 years ago.” The study, conducted by Dr. Bento Lobo, head of the Department of Finance and Economics, examined the pressure and use of the fiber network during the pandemic. EPB compared a typical pre-COVID day (March 4, 2020) to a typical COVID day (December 14, 2020) and saw a 75 percent increase in the total volume of Internet bandwidth usage, reported Smart Cities World. The company has also seen businesses and schools outsourcing traffic from internal networks to the community-wide Internet over the last ten months. EPB delivers electricity to more than 170,000 homes and businesses across a 600 square mile service area. In 2010, EPB said it became the first provider in the U.S. to deliver up to 1Gb Internet speeds utilizing a community-wide fiber optic network, accessible to every home and business in its service area. According to Smart Cities World, key benefits from the infrastructure include:
“The true economic value of the fiber optic infrastructure for EPB’s customers is much greater than the cost of installing and maintaining the infrastructure,” said Dr. Lobo. “Our latest research findings show that Chattanooga’s fiber-optic network provides additional value because it provides high speeds, with symmetrical uploads and downloads, and a high degree of network responsiveness, which are necessary for the smart grid and other cutting-edge business, educational, and research applications.” |
