What many view as the next paradigm shift for mobile technology -- the onset of "5G" -- has set the tech community abuzz with its hype and possibilities, but some experts say don't get too excited about 5G just yet.
"Every generation adds a thing," Joire said. "5G just explodes that to a whole new dimension."
What is 5G?
At its most basic level, 5G is the "new generation of mobile technology," according to Sandro Tavares, the head of 5G and Mobile Networks Marketing for Nokia. Nokia has been working to provide 5G networks for pretty much all of the major service providers in the U.S.
"It is focusing, of course, in delivering data and voice but it does so in a slightly different way that actually allows us to not only provide a better speed, so you will have much faster data speeds than you will have with 4G, it also addresses one other aspect, which is latency," Tavares told ABC News. "Latency is the amount of time that a set of data takes to go from point A to point B."
Joire added that 5G "promises much higher speeds, much larger capacity and much lower latency, which is basically how fast does the network react to things."
"The reason there is a lot of brouhaha around it is because it promises, at least, to bring a whole lot of new applications to the market," she said.
"The rational thing to say is it's 4G on steroids," Joire added. "But at the same time 4G brought us so many things that we didn't have with 3G, so what's 5G going to bring us?"
How fast is this?
"If you’re talking about the maximum speeds you have been seeing in the field right now, they are around 1.5 gigabits per second," according to Tavares. "If you look into the theoretical limits that the industry has been working towards, we are expecting to get up to 10 gigabits per second."
For example, Tavares said if you're trying to download 4K episodes of an entire series, "you’re talking about doing that in a minute or so."
"I saw the other day someone mentioning that with 5G at top speeds you would be able to download the full 'Game of Thrones' set of episodes in just a few minutes," Tavares added.
Joire said simply: "5G is instantaneous."
Beyond cell phones, how will 5G impact our lives?
"Think about how many devices we have in our home," Joire said, such as smart thermostats and speakers. "They all use Wi-Fi, what 5G is promising is forget Wi-Fi, just use 5G."
"Everything is connected, and it's all wireless, obviously the network still installs power, but the base stations of the home might be a thing of the past," she added.
Outside of the home, "the scale is much broader," Joire added.
"Imagine a future, maybe five years from now where every Tesla has 5G and every Mercedes has 5G, and they talk to each other," she said. "It doesn't rely any more on the sensors in the car, it can rely on the communication, because the communication is very fast and can send large amounts of data."
Tavares added that "one of the biggest differences that 5G is going to bring to the future" is that it is "not only going to focus on cell phones, but it is going to be connecting things as well."
"5G is the first mobile-access technology that was born to enable IoT [Internet of Things] from the beginning," Tavares added.
The IoT refers to the interconnectivity of everyday devices through the internet, which allows them to communicate with each other independently. IoT technology has also caused a lot of excitement for how it can be implemented in the creation of so-called Smart Cities, where data shared between devices all throughout the city can be used to greatly improve efficiency in everything from transportation to power.
In the near future, Tavares said he predicts "5G capabilities being available in all kinds of devices" that go "much beyond simply phones or the traditional devices."
Tavares added that he especially sees the tech being useful in the healthcare industry, as a way to improve efficiency, and as well as in education.
"If you use 5G as the underlying connectivity layer for virtual reality and augmented reality education," Tavares said, "you can push training calls to anywhere in the world and the students or employees that are being trained are going to be able to use VR and AR devices to have an experience that are similar to if they were inside the classroom."
"A lot of new knowledge is going to be created and we are going to have to train people a lot faster," he added.
Is this going to be a lot more expensive?
Tavares says he doesn't predict your prices going up that much, saying, "all these things are regulated by the market."
"If you look into the initial packages that the service providers have been offering with 5G, I wouldn't say they are much more expensive than what we’ve seen for 4G, and a lot of them provide a lot more services," he said. "It is in general regulated by the competition, so I wouldn't expect services to be that much more expensive."
Joire added that, "it's definitely an extra cost at this point, but they charged more for 4G back in the day, eventually it gets normalized."
She predicts, "You’re going to pay a premium for the first three years but then it's going to be maybe even cheaper."
When can we expect to see it widely available?
"The initial deployments are already out," Tavares said, adding that all four major operators in the U.S. currently have at least some limited 5G capabilities.
"The deployments are still not widely spread, so with most of them you have a few hot spots," he added. "This is a natural step of the implementation of new technology."
"This will continue to grow through the end of the year and through 2020," Tavares said, adding that he predicts it is still going to continue to evolve and expand "throughout 2021, 2022 and so on."
When should you make the upgrade?
There is a reason that Apple's newest phone, the iPhone 11, which came out last month, doesn't have 5G capabilities, and that's because it's not a good experience just yet, experts say.
"The takeaway big message for customers now is don't bother with 5G, it's not ready yet," Joire said. "It's only rolled out in select cities."
Even within those cities, most of the 5G services are confined to just a few blocks.
"It's small pockets and it's impressive to say the least and you can buy it, but you have to buy a special phone that's more expensive," Joire said.
Joire added that the same thing happened with the 4G rollout, saying, "the first 4G phones were terrible, they lasted two hours on the charge."
Yet now, pretty much everyone uses a 4G phone.
"It's going to happen, but it's not there yet, so you are paying the carriers a premium for a service you can’t get," she added. "I think in a year in a very different picture ... definitely in two years it's going to be worth it."
