Your phone probably has a built-in hotspot feature that enables you to share your internet connection with other devices, regardless of whether you use an iPhone or an Android smartphone.

It's a nice function, but if you use it frequently, a separate mobile hotspot router will probably serve you better.

During my working career, I traveled over 4 million miles and over half of that travel was on trips where I relied on a mobile hotspot router for my Internet connection.

In my first years using a mobile hotspot router, I used hardware from a variety of manufacturers. But, within a couple of years, I had focused on Netgear and have used their routers ever since.

The newest device from Netgear is the Nighthawk M6 Pro and it’s the top hotspot router on the market today. It is important to note that the M6 Pro is only available on the AT&T network in the US. The M6 model is still a superb router and can come unlocked to be used with any telecom vendor.

At this point, you must be asking why? Why have this expensive peripheral when its functionality is bundled already into my smartphone?

It's because mobile hotspot routers are more adaptable and filled with cool capabilities.

First, I use my phone for a variety of purposes throughout the day and don't want to tie it up with always providing the Internet to gadgets. It is inconvenient and severely drains the battery. Two years ago, my wife and I decided to ‘cut the cord’ and get rid of our landline. Now, my smartphone is our primary contact number and I want it always available. The only thing my mobile hot spot router has to do is connect the Internet to all of my accompanying devices.

The Nighthawk M6 and M6 Pro can connect up to 32 devices to the Internet by using the built-in battery to fill up to 2,000 square feet of space with high-speed Wi-Fi for up to 13 hours using the available 5G & 4G LTE networks. If you need more power, connect it to a power bank or other USB charger that’s available.

If your smartphone doesn't have an unlimited data plan, controlling your internet consumption on your phone is crucial. Setting up a separate plan just for data with a cellular carrier for your mobile hotspot router will eliminate those overage costs on your phone’s plan. And in those situations where your device can take advantage of an Ethernet connection, this mobile hotspot router can provide that Ethernet port.

The Nighthawk M6 and M6 Pro's ability to capture cellular signals is also impressive. These mobile routers perform better and had a stronger signal than my iPhone 14 Pro, which makes them a wonderful option for signal-poor locations. In those situations where there appears to be a poor cellular signal, you can connect an external antenna to the TS-9 ports of the router.

Another feature of the M6 and M6 Pro is its ability to provide Internet service even at home. The mobile router can connect directly to your network and allow you to switch over to cellular should your main Internet connection go down.
​
Finally, when you need Internet connections at a campsite, remote construction site or even an emergency scene, use your mobile hotspot router to create a bubble of Wi-Fi service wherever you are. The router will also create a QR code on its display so any smartphone can easily connect to the service with its camera.
Once you’ve used one, you’ll find it really hard to go back to using your smartphone’s hotspot feature.

For years, each cellphone included a tiny smart card called a SIM (Subscriber Identity Module) that contained the “identity” of that device so that it could connect to a specific cellular network.

Data on SIM cards includes user identification, location, and phone number, network authorization information, personal security keys, contact lists, and saved text messages.

When Apple introduced the new iPhone 14, they repeated something they had done years before. They removed a piece of hardware from the phone. First, it was the earphone jack and now it was the removable SIM card and tray. Just like the earphone jack, Apple is touting this change as a boon for consumers. Now, all iPhone 14s sold in the US will use eSIM technology.

"I think it's transformational," Ahmed Khattak, founder and CEO of US Mobile, a mobile virtual network operator that offers service on Verizon and T-Mobile's respective networks. "I think the fact that it even happened ... I'm shaking my head ... because it really democratizes connectivity." 

A type of programmable SIM card known as an eSIM (embedded-SIM) consists of software put onto a chip permanently installed in a device, as opposed to an integrated circuit on a releasable universal integrated circuit card, which is commonly constructed of PVC.
​
Once an eSIM carrier profile has been installed, it operates the same as a physical SIM, complete with a unique integrated circuit card identifier (ICCID) and network authentication key generated by the carrier.
So, why is this change so important? For users, there are three advantages to eSIMs over physical SIM cards:
     •  It’s more secure, because no one can remove it from the phone and use it to intercept phone calls or text messages. (This isn’t the most common form of SIM card hijacking, but it is still possible for someone with physical access to the phone.)
     •  Switching carriers is easier, because you don’t have to wait for a SIM card to arrive or pick one up at a store.
    •  Adding extra lines is easier, because you no longer need a phone with dual SIM card trays. (On the iPhone, Apple supports up to two phone numbers and eight data lines with eSIM.)

An eSIM also benefits phone manufacturers and wireless carriers.
    • By getting rid of the SIM tray, Apple will gain more valuable interior space it can use to install more technology.
     • For carriers, it's a money-saver because they no longer must spend between $10-$20 per physical SIM card.

Like almost every change, there are going to be some growing pains. Not all US carriers are eSIM compatible. Some alternative providers that lease capacity from the major carriers–known as Mobile Virtual Network Operators, or MVNOs, in industry jargon–don’t support eSIM today, which means you can’t use an iPhone 14 on their networks. Some notable examples include Ting, Walmart Mobile, US Mobile, Net10, and Tello.

Conversely, there are small carriers like Mint Mobile, US Mobile and Boost Mobile in the US who have been preparing for this change for some time.
​
"Mint has always believed in digital technologies that enhance and ease wireless services," Aron North, Mint Mobile's chief marketing officer, said in a statement. "Mint has been supporting [the] eSIM for almost two years because we knew, even back then, this innovation would allow users to switch faster and easier."

We’ve covered the four-day workweek in several issues: In the pre-pandemic issue 6-10, we made the case that a four-day workweek could be the norm by 2050. In issue 9-05, the cover article also said the four-day workweek may be coming and potentially much sooner than 2050 because of the pandemic. Neither of these articles, however, looked at the positive impact a four-day workweek could have on the planet and our ecosystem.

When the pandemic hit, the world as we knew it changed dramatically with everyone at home, transportation infrastructure stopped and heavy industrial production drastically curtailed. Emissions from driving, flying and industrial output were dramatically reduced. Air quality in cities around the world showed marked improvement, while global emissions plummeted.

In May 2021, environmental and social justice collective Platform London released a report detailing the ecological impact of a shorter work week. From the earliest days of the pandemic, it was apparent that fewer people commuting translated quickly to reduced pollution, clearer skies, and less congestion on the roads. The impact was global, with Americans reporting less smog in Los Angeles and Europeans famously spotting dolphins in the canals of Venice. While some of this may be exaggerated, the benefits of fewer rush hour commuters are not. Fewer people heading to the office also means a reduction in electricity consumption from fewer lights, air conditioners and elevators running.

Many estimates put the reduction in carbon footprint at around 30% simply by offering one full day off per week. A more modest 10% reduction in hours (roughly three to four hours a week for most full-time workers) still translates to a 14.6% decrease in carbon emissions.

“The one thing we do know from lots of years of data and various papers and so forth is that the countries with short hours of work tend to be the ones with low emissions, and work time reductions tend to be associated with emission reduction,” said Juliet Schor, an economist and sociologist at Boston College who researches work, consumption and climate change.

It’s what you might call a “potential triple-dividend policy, so something that can benefit the economy, society and also the environment,” said Joe O’Connor, chief executive of the nonprofit group 4-Day Week Global. “There are not many policy interventions that are available to us that could potentially have the kind of transformative impact that reduced work time could have.”

Part of the problem is that we can’t forecast what workers will do with that additional day. Many believe, and international studies like those recently done in Iceland prove, that people will eventually gravitate into more eco-friendly activities like hiking, camping and other outdoor activities. But, if people choose to spend their extra time off traveling, particularly if they use planes or automobiles, we may not see any material eco-related benefits.
​
“When we talk about the four-day workweek and the environment, we focus on the tangible, but actually, in a way, the biggest potential benefit here is in the intangible,” O’Connor said. “It’s in the shift away from a focus on hard work to a focus on smart work. It’s the cultural change in how we work and the impact that could have on how we live, and I think that’s the piece that’s really revolutionary.”

We all do everything we can to keep our phones charged, but the time will come when you’ve run the battery down to where you must charge it during the day rather than in the evening while you sleep. Everyone knows you can’t go from zero to full charge in 10 or 15 minutes. But following a few simple rules will help you charge your phone quicker.

Completely Turn Off the Phone. This will not work if you’re waiting for an important call, but when you can, shutting the phone off completely will provide the fastest charge. You may not think that anything is happening when you’re charging, but when the phone is still on, it’s constantly polling its cellular service and even potentially updating apps in the background. All that activity slows the charging process. 

Use a Wall Charger, Not Wireless Charging. Whenever possible, use a plug-in wall charger. We know you can plug a USB cable into your PC or laptop, but that will almost always result in longer charging time. Even if you’re using a charger with lower wattage, an outlet will usually charge faster most of the time. While wireless charging pads are perfect for overnight use, a gold old-fashioned cable plugged into the wall is always better when you have little time to spare.

Don’t Use Your Phone While It’s Charging. It’s so tempting to fire off an urgent text or scroll through Instagram, but leave it alone. It will charge faster.

Consider Getting a Fast Charger. Nowadays, Apple and most Android makers don’t provide a charger with their phones. If you are still using a charger from an earlier phone, it’s probably a slow 5W model. You’re going to need at least a 20W charger to fast charge most current models. Also remember that there is a limit on wattage. You can’t buy a 100W charger and expect a 10-minute recharge. As an example, the iPhone 13 Pro Max has a charging ceiling of 27W.

Here are two of the better fast chargers:

• ArcStation Pro 40W Dual Charger from Spigen. If you have multiple phones in your household and fight for the charger, this dual charger will solve your problems. At 40W, you can fast-charge two phones at once. If one port is being used on its own, it can provide up to 30W for charging larger devices.
• Anker 725 Charger (Nano II 65W). This charger is a multi-tasker. The top port gives 20W of power for phone charging while the bottom can hit 45W. When every device you own is hitting that low power range, this is the charger you want around. Despite its power capabilities versus lower-wattage chargers, it’s still a very small adapter.
  
  

If you’ve noticed cryptic new icons popping up on your phone next to the 5G logo, you’re not alone. Carriers are expanding their 5G networks in a big way this year, and those little “UW” and “UC” logos you’re suddenly seeing represent the different varieties of 5G you’re encountering in the wild. Like Pokémon, but way more confusing.

Isn’t 5G just… 5G? Nope. There are low, mid, and high-band varieties of 5G spectrum. They all provide different levels of data speeds, and all major US carriers use all three. Naturally, they also have different names for them. Depending on your carrier, you may see abbreviations pop up next to the 5G symbol on your phone when you’re connected to the corresponding network. Here’s a quick guide to the different varieties of 5G in the US and the abbreviations carriers have assigned to them.

5G Spectrum Basics. Broadly speaking, low-band 5G has widespread signal reach, but speeds aren’t much faster than 4G LTE (if at all). High-band 5G is very fast—download a movie in seconds fast—but the signal is extremely limited. Then there’s mid-band 5G, which offers a kind of middle ground between the two: far-reaching signal and speeds that are noticeably faster than 4G, though not shockingly fast like high-band.

Verizon
5G UW: Verizon refers to both its high-band and mid-band 5G as Ultra Wideband (UW). Until recently, UW referred only to the high-band network, also called mmWave. Verizon put a lot of energy into building and promoting this network, but even in the limited areas where it exists, the signal can be difficult to find. Starting in 2022, Verizon started lighting up new mid-band 5G spectrum in major cities and classified it, too, as Ultra Wideband. Not confusing at all.

If you see the 5G UW icon on your phone, chances are you’re on the mid-band network. If you’re on mmWave, you’ll notice a big difference in data speeds. But if your data just seems noticeably fast, not ridiculously fast, then you’re probably on mid-band.

5G Nationwide: Verizon refers to its low-band 5G as 5G Nationwide. You’re connected to this network if you just see a 5G logo on your phone without “UW” next to it. And if your reaction to seeing that 5G icon pop up is something like “Huh, this doesn’t seem any faster than 4G,” you’re not imagining things. It’s generally not much faster than LTE. Certain Verizon plans, like its basic 5G Start unlimited plan, only include this low-band version of 5G. 

AT&T
5G Plus: A “5G+” logo on your screen means you’re connected to either AT&T’s high-band or mid-band spectrum. AT&T has put much less effort behind building out a high-band network outside of stadiums and airport terminals, so you’re not likely to encounter it just out-and-about. As of early 2022, mid-band AT&T spectrum is also sort of scarce since the carrier is taking a “kill two birds with one stone” approach to its mid-band expansion. A 5G logo without the “Plus” refers to the carrier’s low-band 5G network, which, it’s worth repeating, is not much faster than LTE.

T-Mobile
5G UC: T-Mobile’s “Ultra Capacity” network technically includes high-band 5G, but the bulk of the network—and T-Mobile’s advertising—is centered on the mid-band spectrum included in the name. While Verizon and AT&T are just getting their mid-band networks up and running, T-Mobile got a head start with the 2.5GHz mid-band spectrum it picked up when it acquired Sprint. If you see that “5G UC” logo on your phone, you can bet that’s the spectrum you’re connected to. 
​
Extended Range: A 5G logo without “UC” indicates that you’re connected to low-band 5G, which T-Mobile calls “Extended Range.” Again, it’s not much faster than LTE, but coverage is more widespread than mid-band or high-band 5G. If you’ve seen a 5G logo on your T-Mobile phone and been unimpressed by the data speeds, that might be why.

If you have an old phone, an alarm system or an ankle monitor, your tech could stop working properly next year.

In 2022, everything from your old phone to your alarm system could stop working as service providers turn off 3G networks in the United States.

Kami Griffiths has a perfectly fine phone. It’s your standard Samsung Galaxy smartphone with all the important apps, a decent camera, and a screen big enough to watch videos. It’s so fine, in fact, she’s had it since 2016 without ever feeling the need to drop hundreds of dollars on an upgrade.

Come next year, though, Griffiths won’t have a choice. That’s the current deadline for when the only cellular network her phone can use will shut down forever.

All the major cellphone carriers—AT&T, Verizon and T-Mobile—are planning to shut their older 3G networks in 2022. Like millions of people in the United States who use 3G phones and other 3G devices, she will have to buy a new device if she wants to text, make calls, or even reach 911.

When these deadlines roll around, Griffith’s own phone could be the least of her problems. Griffiths, who is an executive director and co-founder of Community Tech Network—a nonprofit that focuses on digital literacy in San Francisco—is worried that the group’s clients, a mix of mostly older adults and low-income residents, will find themselves either without a working phone, or could struggle to figure out how to use a new device.

“It’s going to be very difficult for them. They will not be happy,” said Griffiths, who notes older tech users have a harder time figuring out new devices. “If it works fine, they don’t want to change a thing.”

Why Is This Happening? 3G network technology has been around in the United States for two decades. Verizon launched the first 3G network in the nation in 2002, and 4G has been around since 2010. In 2019, carriers started slowly rolling out 5G networks and soon the big companies were launching 5G smartphones. Now they need to focus their resources on building out those newer networks, while saving money on maintaining the older ones.
​
“The reason the carriers would like to get rid of old legacy tech is to free up that wireless spectrum,” said Ian Fogg, vice president of analysis at mobile analytics firm Opensignal. “If you switch off older tech in most markets, most countries, your spectrum license allows you to use that with newer networks like 4G and 5G.”
When Do the Networks Shut Down? The shutdown dates start in January 2022 and are spread out throughout the year. At this time, the dates are all confirmed, and the carriers are proceeding as if they are set in stone. However, the Federal Communications Commission recently accepted comments from groups and people concerned about the shutdown, which could lead to a delay.

Apple is working on technology to detect a user's blood pressure using neural networks and seismocardiogram data, negating the need for a blood pressure cuff.

According to a patent application published Thursday, a wearable device, potentially paired with Apple Watch, might one day be capable of monitoring a user's blood pressure without the need for any additional peripherals.

The patent application, titled "Interpretable neural networks for cuffless blood pressure estimation," explores the use of neural networks to estimate blood pressure using seismocardiogram data. Unlike an electrocardiogram, which relies on electrical signals to monitor a heart rate, a seismocardiogram measures the micro-vibrations produced by the heart beating.

There exist seismocardiogram devices small enough to be considered wearable, though these sensitive systems are typically placed over a user's sternum to measure minute vibrations in or near the heart. How Apple intends to deploy such a device was not discussed in the patent filing.

According to Apple's patent, the system would work by leveraging an individually pruned neutral network accepting a seismocardiogram as input. That neural network would then use the data to estimate blood pressure.

For example, Apple could create a baseline model by training the neural networks with seismocardiogram data and blood pressure measurements from a group of subjects. Using that as a baseline, the system could then prune the model for subsequent users. The initial dataset would be collected from users performing different sedentary activities.

From there, Apple contends that the neural network could be used to accurately estimate a user's blood pressure without a cuff. As the patent points out, the system could use the neutral network "to determine blood pressure based on accelerometer or gyroscope data," which are already present in Apple devices.

Current versions of the Apple Watch can be used to monitor and analyze different types of health data, including heart rates with an optical sensing system, heart rhythms via a built-in electrocardiogram or blood oxygen sensing on the Apple Watch Series 6. Since the Apple Watch release, Apple has been continually expanding the device's health toolkit, and Apple may be looking to build out a set of health-minded accessories. 

The patent lists Siddharth Khullar, Nicholas E. Apostoloff, and Amruta Pai as its inventors. Among them, Apostoloff has been named on a previous patent dedicated to facial analysis and emotion detection.
​
This isn't Apple's first patent focused on blood pressure monitoring. In 2020, the company filed a patent application for an Apple Watch-supported system that could use pulse transit time to measure blood pressure. Another system could use pressure sensor data, and Apple has explored how to monitor blood pressure without a cuff in the past.

The City of Las Vegas is home to 650,000 residents, with the greater Las Vegas area attracting 42 million annual visitors. The City of Las Vegas, working with technology and business solutions provider NTT, has expanded its efforts to become a smarter city and provide safe, reliable, and efficient civic technology that stimulates economic growth and offers better experiences for its residents and visitors.

City officials are seeking to improve interoperability among all public service sectors through open-source data sharing and real-time data analytics. They have deployed various tech solutions in the past two years that have already changed city safety.

The city’s smart city charter focuses on six major areas:

• Public Safety: Solutions should better inform first responders and decrease response times.
• Economic Growth: Infrastructures will promote new business models and lead to new job opportunities.
• Mobility: New connected vehicle infrastructure and data analytics will enable safer, more reliable, and energy-efficient mobility options.
• Education: Expanding collaboration with universities will support education initiatives and prepare the future workforce.
• Social Benefit: Programs for underserved communities will help establish demographic equity.
• Health Care: Connected and intelligent medical devices will encourage a broader view of well-being.

In this article, we will focus mainly on public safety initiatives and also touch on some social benefits.

Improving Safe Mobility. This pilot project was designed to decrease traffic congestion and help city officials address the problem of drivers accidentally driving the wrong way on streets. Sensors using lidar placed at various streets in Las Vegas could detect collisions, near misses, how many times cars went the wrong direction, and even resulting decreases in congestion after roadway improvements.

Edge data centers can quickly process and analyze massive amounts of data and send back near real-time alerts and suggestions for traffic control, amber alerts, and more. The connected data from all over Las Vegas streets also helps first responders react more quickly.

Through the pilot program, wrong-way driving was reduced by around 40%.

Expanding to Smart Park Initiative. Following an earlier trial at two park locations, Las Vegas has started expanding its smart park initiative to 12 more locations in a public safety effort. Deploying smart city technology in parks has allowed officials to monitor large crowds, gunshots, vandalism, breaking glass, and more.

Michael Sherwood, director of innovation and technology for the city of Las Vegas, said that understanding how many people visit parks and which facilities they use can help improve maintenance and operations, inform decisions about expansion and services, and protect residents.

Remote monitoring in the parks can improve efficiencies for public safety personnel, too. If sensors detect a visitor in the park after closing hours, automated recordings and remote systems can address the person before alerting officials.
​
As Las Vegas continues to accelerate its smart city projects throughout the city, it’s learning that a connected society can directly benefit citizens and is looking ahead to how smart city technologies can extend further to stadiums, shopping malls, and manufacturing facilities.

During the COVID-19 pandemic, which has ushered in significant changes to media consumption habits and how major entertainment companies promote and display their offerings, we have watched considerable changes occur in at-home entertainment viewing.

“This pandemic has forced consumers to recalibrate their entire lives,” says University of Virginia Darden School of Business professor Anthony Palomba. Professor Palomba is an expert in media management. This interdisciplinary academic discipline examines how audiences consume media and entertainment products and services, as well as how entertainment companies compete amid shifting consumer preferences.

“What matters to them? What doesn’t? I think consumers are getting to know themselves a bit more. Rather than being told what is good by advertisers, they have to consider for themselves what is good,” said Palomba.

We are all consumers. We have been stopped in our tracks for nearly an entire year. We have reprioritized our lives. This impinges upon advertisers’ and marketers’ abilities to consistently reach and speak to us.

Professor Palomba continues: “Consumers’ acumen over available entertainment and media options has risen quite a bit. Consumers have had more time at home to watch, view, subscribe and try out these options. Marketers must consider how to position entertainment products and services to consumers who have greater market awareness. More consumers have begun to consume digital entertainment, and podcast audiences have swelled while consumers work from home. There is also intensified yearning for immersive escapes into other worlds and realms, which I think has fueled interest in the PlayStation 5.”

“Consumers are seeking entertainment brands that they can trust. It is astounding to think that Disney + got to 50 million subscribers in five months. It took Netflix seven years to reach that milestone. This business feat is symbolic of consumers’ predominant need to find trusted, feel-good, high-quality brands as consumers reconcile bills against unemployment, salary cuts, and other unknowns.”

This leads to a question: Do consumers enjoy searching for videos and finding the unexpected? With colossal and meticulous algorithms used to determine consumer preferences on streaming video on demand platforms and new [streaming video on demand] program advertisements, the joy of discovery may very well be undermined for consumers. Part of the human experience is discovery. Ensconced in the unknown, will we find something meaningful? Past studies have illustrated that engaging in discovery and exploratory activities is restorative and renews our perspectives about ourselves, giving us confidence and a better feeling about our future.
​
Now, more than ever, consumers need reasons to be lost in discovery.

When we think about privacy and who can access our location data, we’re often focusing on our phones and not on the machine that actually takes us places: our car. A recent report from NBC News goes into just how much data is collected by our vehicles and how it can be used by police and criminals alike.

Your car, depending on how new it is and what capabilities it has, could be collecting all sorts of data without your knowledge – including location data, when its doors were opened, and even recordings of your voice. The NBC article uses the example of Joshua Wessel, a man charged with murder because the victim’s truck has a recording of his voice at the time of the killing. The report also looks at a company called Berla Corp., which has built a business out of extracting that data on behalf of the police.

In broad strokes, it’s hard to guarantee any kind of data protection, simply because cars collect so much sensitive data. Berla’s software boasts the ability to read the unique IDs of Bluetooth and Wi-Fi devices that have connected to a car’s infotainment system, as well as call logs, contacts, and text messages. But infotainment data isn’t all it can read – it can also look at the logs kept by the car’s internal computer, revealing when specific doors were opened, as well as providing a location log from its built-in GPS.

It’s not just the police that can get at this information. NBC mentions an Australian man who used an app to access live data from his ex-girlfriend’s Land Rover. Not only was he able to access live information about the car, but he was also able to control it, remotely turning it on and off and opening windows.
​
The heart of the problem is that we’re sharing our private data with more and more devices, and the systems we rely on to keep that data safe are getting more complicated. If we really want to deal with the issue, we may have to take a hard look at our cars and start thinking about how much data they need.
