When did 5G come out? The long, complicated history of its release

Although 2022 will likely be heralded as the year 5G truly went mainstream, we’ve traveled a long and winding road to get here. Carriers began actively working on preparing this leading-edge cellular tech as early as 2015, but it wasn’t until the end of 2018 that the first 5G mobile towers came online. It also took until 2020 before 5G was much more than a curiosity for early adopters.

Although previous cellular technologies like 4G/LTE also spent a long time in the research and development stages, those didn’t experience nearly the same growing pains that 5G has. When 4G/LTE services began rolling out broadly in 2011, it was the same basic technology across all the major U.S. carriers.

Things have been considerably more complicated with 5G. Since the newer technology promises the kind of performance previously exclusive to wired broadband services, it comes with more demanding requirements and runs over a much wider range of frequencies.

This has made deploying 5G somewhat more challenging as carriers try to find more radio spectrum to carry the best 5G signals. They also need to keep their 4G/LTE networks running at peak performance while sharing the airwaves with new 5G services.

The humble beginnings of 5G

Many folks don’t know that the first 5G deployments in the United States weren’t for mobile devices at all. In 2017, the carriers began trialing fixed wireless 5G services as a replacement for wired broadband home internet. Closed trials of 5G home internet ran well into 2018 before becoming commercially available later that same year.

It wasn’t until early 2019 that the first 5G mobile networks rolled out. Verizon led the way in April with a relatively small 5G footprint in core areas of Chicago and Minneapolis, arguably beating out three South Korean carriers to become the first commercial 5G smartphone service on the planet.

Verizon expanded its service to several other cities throughout 2019, including Denver, Providence, St. Paul, Atlanta, Detroit, Indianapolis, Washington, D.C., Phoenix, Panama City, New York City, Dallas, Omaha, Houston, and Boston.

The carrier had all these cities under its belt before rivals T-Mobile and AT&T turned the switch on their own 5G networks, but there was a big catch. As a result of Verizon’s use of the extremely high frequency (EHF) — and extremely short range — millimeter wave (mmWave) spectrum, 5G service in each of these cities was confined to very small and specific areas. Stray more than a block away from a 5G zone, and you would quickly find yourself back on the carrier’s standard 4G/LTE service.

The upside is that if you were near one of these rare mmWave 5G towers, you could experience phenomenal speeds. It wasn’t uncommon to see speeds in the 500 to 1,000Mbps (1Gbps) range.

Sprint had also begun dipping its toes into 5G in early 2019, using the mid-band 2.5GHz spectrum that was already carrying its 4G/LTE traffic. Those deployments were relatively short-lived, though, as a year later, it would find itself folded into the new T-Mobile, which had other plans for that spectrum.

Expanding 5G across the nation

While Verizon focused on delivering the fastest possible 5G speeds to tiny areas, AT&T and T-Mobile were working instead on building more expansive 5G networks using low-band frequencies that could travel much greater distances.

Both carriers turned on their larger 5G networks in December 2019, with T-Mobile claiming its network covered 200 million people out of the gate, while AT&T only promised coverage for “tens of millions” of its customers. This isn’t to be confused with AT&T’s 5G Evolution (5GE) network, which launched in 2018 but was really just a misleading name for its advanced 4G/LTE services.

The two carriers used different pieces of the low-band spectrum, with AT&T using higher frequency signals that were paired with its 4G/LTE network in key cities — only about 15 during its initial launch — while T-Mobile piggybacked on its 600MHz spectrum that was already covering vast swaths of the countryside. By mid-2020, T-Mobile was able to leverage that spectrum to boast 5G coverage in all 50 states, including Alaska.

Verizon didn’t join the nationwide 5G party until late 2020 when it rebranded its mmWave 5G service as its 5G Ultra Wideband (5G UW) network. It did this to make room for a new 5G Nationwide offering that it said would deliver 5G to 200 million more people throughout 1,800 towns and cities across the nation.

The first 5G smartphones

The earliest 5G deployments were exciting but a bit premature — especially Verizon’s. When the first mmWave cells went live in Chicago, there were barely any handsets that supported 5G at all — much less the mmWave flavor of 5G that Verizon used.

In fact, the only compatible handset on the market at the time of that initial 5G launch was Motorola’s midrange Moto Z3, which was sold exclusively on the Verizon network. It also required a separate Moto Mod add-on module to provide 5G compatibility.

The Moto Z3/Moto Mod solution was a strange arrangement, but fortunately, 5G enthusiasts didn’t have to wait long for more options. Samsung’s Galaxy S10 5G and LG’s V50 ThinQ came along in May, followed by the Huawei Mate X, OnePlus Pro 7 5G, Xiaomi Mi Mix 3 5G, and ZTE Axon 10 Pro 5G.

Those early 5G smartphones also had another critical catch. In 2019, Verizon and Sprint were offering 5G services but doing so on different frequencies. Early 5G smartphones like LG’s V50 ThinQ and the OnePlus Pro 7 5G couldn’t pack in all the necessary frequencies for both carriers, so they were sold in two different versions on each carrier. This meant many early Verizon 5G phones wouldn’t work on Sprint and vice-versa.

Meanwhile, Apple released its iPhone 11 lineup in 2019 without no 5G support at all. The message from Cupertino was clear: 5G wasn’t a big enough deal yet to warrant its inclusion in Apple’s flagship smartphone lineup.

That’s a fair assessment since Apple builds its products for the masses, and 5G was available to less than five% of U.S. consumers in September 2019. That had changed significantly by the time the iPhone 12 was released a year later, and 5G has been standard on every iPhone since with support for every 5G band from T-Mobile’s 600MHz low-band to AT&T’s 39GHz mmWave in every U.S. model save the lower-cost iPhone SE.

T-Mobile takes the lead

By November 2019, Verizon had 5G coverage in small areas of 16 U.S. cities, and Sprint claimed around 16 million people under its 5G umbrella.

So it’s easy to appreciate how big of a deal it was when Go to Source
