5G myths: What’s true and what’s not about the next-gen network


Angela Lang/The Techy Trends

The next generation of high-speed mobile data, known as 5G, is already live in a handful of areas in the US, as well as other parts of the world, including countries such as the UK and Australia. But as this network rolls out, many misconceptions and confusion around the new technology remain.

This isn’t completely surprising — 5G will have an impact on many people’s lives all around the world, so there are understandably still a lot of questions being asked. As the 5G rollout continues throughout 2020, it’s predicted that there will be 1 billion 5G customers by 2023. Not only will these 5G networks connect users to a superfast mobile network, but many other industries will benefit from the faster connectivity of 5G as well, like self-driving cars, drones and the internet of things, to name a few.

To learn more about 5G, we’re debunking a few 5G myths. And if you want to know more about 5G in general, read our FAQ: Everything you need to know about the 5G revolution.

Is 5G safe?

One of the biggest concerns people have about 5G is that the network’s radio frequency will be unsafe, expose people to radiation and cause cancer. The fears aren’t completely unfounded — a 2011 report from the World Health Organization suggested that cellphone radiation should be listed as “possibly carcinogenic to humans.”  In 2016, a study funded by the US government showed a link between radio frequency radiation and cancers in rats. And popular phones like the iPhone and Galaxy handsets may exceed the level of radio frequency radiation allowed by the FCC.

But the link between cancer and phones may be overstated. For one thing, a number of things that we encounter every day are considered to be carcinogenic hazards to some degree, including diesel fuel, aloe vera and pickled food. The aforementioned 2016 study also exposed male rats to levels of radiation that exceeded radiation levels that humans would come across from their cellphones.

Though it’s too early to be 100% confident, we do know that on Aug. 8, after more than six years of research and review, FCC Chairman Ajit Pai circulated a proposal to deem cellphones, including ones that use 5G, as safe. As The Techy Trends Senior Writer Maggie Reardon reported, that includes “current exposure levels for cellphones, wireless towers, Wi-Fi routers and all other devices emitting RF signals.” In addition, “Agency officials … don’t have any concern for new gear using 5G technology, including gear that uses millimeter wavelength frequencies.”

5G and your health


Will 5G replace 4G? Will I need a new phone?

While you will need a 5G phone to access a 5G network, it doesn’t mean you need one to reap some of its speed benefits. In fact, as the next-gen network rolls out, you may experience faster speeds on 4G as well (more on that below). In addition, 5G is not replacing 4G altogether. Rather, it’s building on top of existing 4G networks. All major carriers in the US and around the world are a ways away from a solid network-wide rollout. Even if 5G is available in your area, your phone isn’t obsolete just yet. It will still work perfectly fine on 4G.

But will my current phone be faster?

According to a GSMA Intelligence report, 15% of global mobile connections will be on 5G by 2025. By that same year, 4G LTE usage will be about 59% — an increase from 43% in 2018. In short, 5G will not replace LTE in the way that 4G did with 3G when it launched.

Taking that into consideration, those with 4G phones may see a boost in speed as 5G networks roll out. This is due to two reasons: dynamic spectrum sharing and carrier aggregation. Coming to the US in 2020, DSS technology allows carriers to employ the same spectrum band for 4G and 5G. As people transition to 5G, “lanes” for 4G will be kept open for smart home devices and users who aren’t on 5G yet. As more people leave 4G, its capacity increases and so will speeds.

Carrier aggregation allows carriers to combine 4G signals with other 4G signals, which will result in “a huge performance and capacity lift,” according to Verizon’s vice president of technology, Heidi Hemmer. 5G builds on 4G technology too, so you’ll also experience lower latency periods (aka: the time between when your phone pings the network and when it responds) as carriers develop their 5G networks.

For more on this topic, read No, 5G isn’t going to make your 4G LTE phone obsolete.

Will 5G force me into an unlimited data plan?

Most likely yes, for now. In the US, Verizon has four unlimited plans and three of them include 5G for an extra $10 a month on top of the regular plans. To experience 5G on Sprint, you will need an unlimited plan as well. T-Mobile (which is due to merge with Sprint), told PCMag that its 5G service will be unlimited but won’t cost more than its existing 4G plans. AT&T’s 5G network is currently for businesses only, but the 5G plan for its $499 hotspot, Nighthawk, will cost $70 a month for 15GB when it’s eventually released to consumers.

In general, 5G plans will cost more but don’t expect carriers to be completely clear and transparent about it. As The Techy Trends Executive Editor Roger Cheng reported, “LTE didn’t cost any more when it first came out; you just needed to buy a new phone. But pricing models do change over time. Since 4G launched, carriers both took away unlimited plans and brought them back.”


Make sure your streaming plan includes HD video.

Will 5G allow me to stream the best-quality video at all times? 

Not necessarily, as this depends on your video streaming service provider and your plan. Netflix, for example, has a Basic Plan that only lets you stream videos in standard definition. There is a more expensive Premium Plan too, where you can watch high-definition and ultra high-definition videos when available. And while most devices support Hulu’s HD programming, its 4K Ultra HD content is currently only available on Apple TV (fifth generation or later) or Chromecast Ultra. Disney Plus, however, will give all subscribers access to 4K and HDR high-quality video. 

Will 5G really allow for remote surgeries and autonomous vehicles? 

Back at MWC 2019 in February, The Techy Trends Senior Reporter Shara Tibken witnessed what was billed as the first live surgery over 5G that involved a doctor consulting the surgeon from another location. The doctor was able to relay instructions and draw on a video of the patient in real time, as surgeons were performing the procedure.

While entire surgeries performed over 5G isn’t going to be possible right away, there is little doubt that 5G will revolutionize the health care industry. Surgeries performed in remote areas with a doctor located in a different location will be possible over 5G since the network can handle the high bandwidth, quick responsiveness and low latency required to carry out such an endeavor.

5G lets you remotely perform surgery with a robot arm


5G can benefit the industry in other ways. High-definition streams and sophisticated imaging of patients can bring health experts into the home, and emergency responders can get immediate mapping and terrain information when they are out in the field (say, a firefighter receiving the schematics of a burning building in real time on an AR headset).

As for autonomous cars, that won’t likely come around for many years, if at all. But 5G is seen as “an enabler” and an “accelerator” for self-driving cars when it comes to communication, latency and bandwidth, according to Dmitri Dolgov, chief technology officer at Google’s Waymo self-driving car business, in an interview with VentureBeat.  

In addition, The Techy Trends Senior Editor Stephen Shankland reported that “C-V2X, a communications technology using the same 5G networks coming to our phones, will allow vehicles to communicate wirelessly with each other, with traffic signals and with other roadside gear, improving both functionality and safety. “


Will 5G really close the digital divide?

Not exactly. While the US is ahead of some countries, such as China, Japan and Russia, with its 5G rollout, the switchover from 4G to 5G will be staggered. That means that while some pockets will have 5G initially, many larger areas will still be on 4G for a while. There are also many agricultural and rural areas in this country that still don’t have internet, let alone high-speed internet or mobile data. This upcoming 5G era may actually widen the gap even further.
