The Density sensor tells you how crowded certain places are, so you can avoid long lines

density sensor helps you avoid crowds and long lines
Intense agoraphobia? There’s a sensor for that. Thanks to a brilliant new device named Density, you’ll never have to wait in long lines or brave enormous crowds again — not if you don’t want to, at least. The tiny sensor gives its users a sense of how many people are going into or coming out of a building at any given time, which often provides a solid estimate of how crowded or quiet a location is. And while the advantages of such a tool are obvious for a patron, Density notes that stores, shops, and restaurants could also benefit from this technology, which is why they’re encouraging a number of locales to install the Density sensor to doorframes and entrances.

According to the tool’s website, “Our sensor gets attached to a place’s entrance, measures anonymous movement as people come and go, and generates real-time and historical data that can be integrated anywhere.” By using infrared light that measures movement, Density is able to track population from a broad, high-level stance — it “cannot capture any personally identifiable information about consumers.” This means that without any sort of invasive or creepy practices, the sensor is able to tell store owners what their peak times are and when business is slow, and consumers can make use of the same information to strategically plan their day.

While the technology behind Density is relatively straightforward, its multitude of applications in real-life settings makes it particularly attractive for both people on the go and businesses looking to capitalize on downtime. With its easy (and cheap) installation and open-source API, a number of applications are already using the sensor. For example, Requested, an app that gives diners the chance to ask for discounts when traffic at popular restaurants is low has adopted the technology, as has Workfrom, which alerts its visitors to real-time capacity at various co-working spaces.

Currently, Density is selling its services for $25 per location, per month, but notes, “Inventory is limited. Access will be given to select partners.” But hopefully, with rising popularity, Density will become a staple across a variety of businesses, putting an end to (surprising) long wait times and overcrowding.

Google Maps is adding new shopping tools for the holiday season
Person using Google Maps on a smartphone.

Google has announced several new features in Google Maps to keep you sane this holiday season by helping you avoid crowds, find your way around the malls, and even get your holiday dinner shopping done.

First off, Google is expanding its crowdedness data features for public transit and specific stores into a broader tool that it's calling "Area Busyness." This will show you how many folks are gathering in a specific neighborhood, rather than an individual store. As Google explains, you can use this information however you like, whether you want to steer clear of the crowds or seek out the hottest spots in town.

How far away are we from mainstream 5G home internet?
t mobile 5g home internet.

From 5G smartphones to businesses using 5G solutions for better management and rapid scaling to health care industries implementing 5G tech to improve efficiency and save lives, the 5G seems to be penetrating nearly every industry. But despite 5G home internet being presented as a panacea, especially for Americans living in rural areas with limited broadband options, it still hasn't taken hold, with just hundreds of thousands of subscribers using the service compared to the hundreds of millions of 5G mobile customers. 
That raises questions about why 5G isn't currently popular for home internet use -- especially in rural areas that could benefit the most from it -- and what the challenges are in terms of adoption. We talked to experts to find out. 
How widespread is 5G home internet currently? 
T-Mobile launched 5G Home Internet in April this year, making 30 million households eligible for the service (but not all of them have made the switch yet). It also subsequently expanded its availability to 51 cities and towns throughout Florida, Georgia, North Carolina, and South Carolina. "While fixed wireless internet isn't yet available to every American, we're projected to serve 500,000 households with home internet by the end of 2021," said Kaley Gagnon, vice president of emerging products at T-Mobile.  

A spokesperson from Verizon told Digital Trends that it experienced a gain of 55,000 net subscribers in July, August, and September. The company reached 150,000 total subscribers on fixed wireless access at the end of the third quarter, the spokesperson said.
However, some experts like Jay Akin, CEO of Mushroom Networks, a networking company that builds advanced routers and appliances, believe getting an exact number of 5G home internet users can be difficult as carriers avoid breaking down their subscriber numbers with respect to LTE-versu-5G for fixed wireless access). "Majority of those subscribers are LTE and not 5G so far," he said, adding that "5G home internet subscribers are lower than 100,000 people in the whole United States among all carriers."
Those aren't promising numbers, especially compared to the slow pace of 5G carrier rollout, which covers 75% of the U.S. on paper, but with only 25% spending online time actually connected to 5G. 
Four big barriers to 5G home internet 
Despite the widespread availability of 5G devices and an increasing number of discussions on applications of 5G technology, data shows 5G home internet hasn't yet picked up steam. Infrastructural, economic, and sociocultural factors continue to be major obstacles to 5G home internet becoming mainstream.
One of the major concerns for many users is performance, especially now that everything (school, work, socializing, and even health care) has moved online. 
"According to the 2021 EY Digital Home survey, 57% of respondents said that dependability is more important than speed and that reliability is the No. 1 deciding factor for choosing a broadband provider," said Vincent Douin of EY. "Reliability has now overtaken price considerations when it comes to choosing a broadband provider, and 51% of respondents said they would worry about inferior broadband performance if they switched providers," he added.

Ford's new all-electric truck, the F-150 Lightning, will ship with 5G connectivity in 2022 courtesy of AT&T. The announcement came on Tuesday morning as part of the AT&T Business Summit, a virtual event to be held by AT&T on October 27 and 28.

The F-150 Lightning is currently under construction at Ford's Rouge Electric Vehicle Center in Dearborn, Michigan, which is built on the 43-year-old Dearborn Rouge factory. AT&T's 5G network is being implemented to help with the construction, design, safety protocols, and eventually the wireless updates required by the Lightning once it's on the road.
