What Is 5G, And Why Should You Care?

What Is 5G

You’ve heard plenty about the 4G revolution, but you may have been hearing more and more recently about 5G—and wondering what exactly it is and why you should care about it. If so, you’re in the right place! This guide will help explain everything you need to know about 5G, so that you can get on board with this new technology from the start and take advantage of its benefits to make your daily life easier and better connected than ever before. Let’s get started!

How Much Faster Is 5G Than 4G?

What Is 5G

So what is 5G exactly? Well to be frank and simple, it’s next-generation cellular data transmission technology. So naturally, you would think that LTE or 4G is better than 3G or 2G as a standard right. Wrong! This has been answered many times already so we’ll cut right to the chase. In short words 5th Generation Wireless Technology has 10x more bandwidth than existing standards which means theoretically you could download movies in fractions of seconds. That’s why it took Netflix two years to make that jump from HD to Ultra HD. At first looks like no big deal but if you dig deeper into what benefits actually bring it changes our world completely.

1G, 2G, 3G, 4G, 5G

What Gs Have We Been Up To Since 1980? : What is 5G? It’s pretty simple to understand: It stands for 5th generation. With every generation that comes around, network technologies get faster and more robust. Every generation provides faster data speeds and better coverage than what came before it. Here's a brief overview of what's come before now — as well as a sneak peek at 5G and its capabilities. 1st Generation – Analog Networks In 1973, AT&T launched their first cellular network in Chicago using analog communications technology (it would take another 10 years before handsets could communicate on those networks). The system used FM signals rather than digital ones to achieve maximum range with minimal interference.

How 5G Works

The concept behind 5G is similar to what’s already powering your phone. It works by sending out high-frequency waves that will then bounce off of nearby objects and return to a cell tower. By reading how long it takes for a signal to get from its source to an object and back again, these cells can pinpoint exactly where you are—and what you're doing with your phone. That means 5G will be able to identify not only when you’re in front of your TV but also if you walk into another room where there’s one as well. It'll know if you watch Comedy Central or HGTV (or YouTube) on your laptop and which shows you like best so it can suggest more videos down the line. 5G's hyperlocal focus makes it far more powerful than previous generations of cellular technology. It's also much faster: 5G networks should be capable of speeds up to 20 gigabits per second, compared to 4G's maximum of 1 gigabit per second. Those speeds make 5G ideal for streaming ultra-high-definition video and virtual reality content at home or on your phone.

Where Is 5G Available?

  • 5G is now available nationwide, but different carriers approach it differently, so you may have different experiences depending on where you are.
  • There is a slower "national" 5G that relies on shared 4G channels, a midrange 5G in 42 metro areas, and a fast high-band 5G in 60 metro areas. The Verizon network coverage map is here. Verizon says they will soon start showing mid-band coverage on the maps. (As of this writing, mid-band coverage isn't shown.)
  • With T-Mobile, you can use a coverage finder here to check T-Mobile's low-band 5G across the country; a faster mid-band network covering more than 200 million people; or limited high-band coverage for which I have not seen a recent update.
  • There are slow low-band connections under the AT&T network across most of the country, mid-band connections in eight cities, and high-band connections in several "venues" like stadiums and campuses. There is a low band called "5G" and a high band called "5G+." The company offers low-band maps and high-band venue lists here.

Which 5G Phones Are Coming Out?

The first 5G phones are now commonplace; any phone over $300 will have them. In terms of AT&T and Verizon, mid-band is next on the agenda. According to Verizon, the Apple iPhone 12 and 13 series, the Samsung Galaxy S22+ series, the Z Flip 3, and the Z Fold 3 are all mid-band devices; the Google Pixel 6 and 6 Pro will follow soon. More mid-band smartphones will be released this year, and more existing models may be certified over the coming months. AT&T has a similar list, including the Galaxy A33 5G.
Many AT&T and T-Mobile phones lack high-band 5G technology since low- and mid-band 5G is less expensive to implement. However, I'm undecided whether this matters. There are a lot of high band airwaves owned by the companies, and more technology is better. It is unclear what advantages high-band will provide in AT&T and T-Mobile phones since they have been very quiet about what they plan to do with them. For those who like to cross all their i's, the OnePlus 9 Pro, Samsung Galaxy S21 series, Galaxy Z Flip3 and Fold3, Samsung Galaxy Note 20 Ultra, iPhone 12 series, and Pixel 5 all offer high-band.
Many other countries now offer 5G phones, including models from Huawei, Oppo, Realme, Xiaomi, and more. Generally, they can't work on US 5G networks as they don't use our frequency bands; they use European and Asian mid-band systems that aren't available here.

Is 5G Safe?

What Is 5G

Definitely. There are lots of conspiracy theories online that blame 5G for everything from cancer to coronavirus, but they all fall apart when actual facts are brought into the picture. Radio frequencies that have been in use for decades are used in low-band and mid-band 5G. Since 1952, UHF TV bands have been used for low-band 5G. Sprint's mid-band has been around at least since 2007; some of its parts date back to 1963.
In recent years, the airline industry has expressed concern about the new C-band networks of AT&T and Verizon, saying the frequencies are too close to those used by radio altimeters, which measure airplane distances from the ground. A 400MHz space exists between the cellular networks, operating at 3.7 to 3.8GHz, and the altimeters, operating at 4.2 to 4.4GHz, but some models do not have filters to block signals on other channels. FCC and FAA have been negotiating compromises regarding this issue, such as certifying altimeter models with filters and creating "exclusion zones" where there are no C-band signals near airport approaches.
Signal power is critical. Wireless technology uses the same frequency as microwave ovens. People believe millimeter-wave signals are microwaves since millimeter waves are technically microwave signals. 5G systems, by contrast, are closer to fireflies than blowtorches.
The strongest effect of mmWave at levels higher than those used by any 5G network, when operating at levels higher than those used by humans, is to make things slightly warmer. There is no discernible effect from 5G networks at the levels they use.

What's 5G For?

  • In the first instance, 5G will be used to connect the home internet. There are two companies offering home internet service based on their 5G networks, T-Mobile and Verizon. We expect our 4G networks to be unable to handle those hundreds of gigabytes of data usage per month that our home subscribers typically use. These networks are adequately equipped to handle those demands.
  • Using 5G home internet is more convenient for carriers than laying fiber-optic lines house-by-house. Carriers need only install fiber optics between cell sites every few blocks, and then provide wireless modems to customers instead of digging up every street. We reviewed T-Mobile's 5G home Internet service, which we found to be better than DSL, but not close to fiber.
  • It's not the first time people are using the Internet at home. There are a lot of new applications that are waiting for 5G coverage with speeds that are noticeably faster than 4G, and the hold-up at AT&T and Verizon has prevented us from reaching the next step.
  • Robot and drone remote control is another 5G application that we are beginning to see. Due to 5G's low latency, remote pilots can control vehicles from a distance without lag. Additionally, thanks to 5G's higher bandwidth, they can stream multicamera video from their vehicles to maintain a visual of where they're going. The Bell 5G network is helping Tiny Mile deliver snacks in Toronto with its delivery robots.
  • 5G-enabled drones have been used by Verizon to transmit video and sensor data back to a central location.
  • While watching an NFL game on Verizon, viewers can switch between seven high-quality camera perspectives. There are dozens of cameras around a hockey arena that allow you to view 360-degrees of the action with Bell in Canada.
  • 5G can handle more connections simultaneously than 4G, meaning it will be especially useful to people on-site in these areas. If we ever get back to things like concerts, sports events, and parades (if we do), a 5G network won't choke up as much as a 4G network does.
  • Apparently, 5G could eventually become a key part of augmented reality and the "metaverse." It's argued that if you're going to wear AR glasses outdoors, display business ratings above restaurant doors, and talk to holographic ghosts of people walking beside you, you're going to need 5G's low latency and reliable speeds.
