The race to build out “fiber in the sky” is on.
The next-gen mobile standard known as 5G, the fifth generation of the technology, is poised to create a new platform that is not just faster, but much more agile than today’s state-of-the-art 4G (also known as Long Term Evolution, or LTE) networks.
Expected to debut wide in the next two years, it’s the latest in the continuum of every innovation in wireless technology, and it promises to disrupt — if not complement — many industries with lightning-fast communication speeds.

5G will roll out as a network of cell sites offering gigabit-level speeds (100X faster than today’s highest speeds) over fiber lines, and lower latency (no more hourglass or beachball icons!)
The technology will also underpin a vast array of fixed (non-mobile) and mobile devices, services, and applications across an array of industries, including entertainment, education, music, and medicine. Consumers need only a modem to connect.
Deployments of 5G are already underway using pre-commercial technology by the usual suspects — the incumbent mobile network operators — but there are a host of new providers, including cable operators, that have become increasingly eager to add mobile and wireless to their service arsenals.
The first anticipated type of 5G-based services will be fixed wireless data offerings that can deliver speeds in the neighborhood of 1 gigabit per second to the home or business. The implications for the Internet of Things, in a world where every home appliance and gadget is dependent on robust wireless connections, are enormous.
Blazing Fast Internet
For traditional services, imagine downloading a full two-hour movie, or an entire semester of classes to a student, in mere seconds — while also supporting the massive data rates that will be required by new virtual reality and augmented reality services.
Further out, 5G will also be mobile, with sub-millisecond latencies that greatly cut down the time it takes for data to be transferred after it is requested, and will be a major requirement, for example, for mobile networks that can ensure that self-driving cars stay connected and can navigate the streets safely.
For now, despite its futuristic reputation of sensors everywhere, 5G is saddled with technical hurdles. For example, 5G signals, particularly when delivered in the upper, millimeter-wave frequency bands, will need a clear path, as their performance is vulnerable to obstacles such as trees and buildings.
For the cable industry, 5G is viewed as a threat and an opportunity. While 5G could create a new speedy broadband rival, 5G will also require the deployment of millions of dense, high-capacity small cells that are in stark contrast to the macro-cell networks used by today’s 4G networks. And it so happens that cable’s fiber-rich network is well positioned to provide those critical backhaul and powering requirements. That could be a major moneymaker for the cable guys.
When will all of the pieces fall into place? Though some 5G-based fixed wireless services will take hold in 2018, the big ramp for the technology isn’t expected to emerge until 2020.
Several mobile service providers, cable operators, and startups like Starry are already well downstream with 5G-based fixed wireless tests and deployments. The mobile aspects of 5G aren’t expected to take hold in a big way until 2020.
In the meantime, initial 5G-based fixed wireless deployments could put some pressure on wireline ISPs.
“The use case [for 5G] I get most excited about is the opportunity to have a nearly nationwide broadband footprint,” Randall Stephenson, AT&T’s chairman, president and CEO, said on the company’s Q4 earnings call, expressing confidence that 5G could serve as a fixed-line replacement for both business and residential customers.
“The capacity is there, the performance is there. There’s going to be full gigabit throughput,” he said.
Mobile Making a Move
But that work isn’t stopping progress on mobilized 5G even before there are smartphones and other mobile devices that will support it. AT&T, for example, plans to launch a mobile form of 5G by the end of 2018 in about a dozen markets. However, the initial deployment won’t involve direct integration with laptops, smartphones, or tablets, but instead rely on a smaller router-like device that can connect other devices to the 5G network.
“Think of this as a puck,” Stephenson said of the new device. He wants AT&T to push mobile 5G forward before handsets that support the next-gen wireless technology become available.
T-Mobile will be keying its 5G strategy on spectrum in the lower spectrum bands. While that will address the mobile opportunity, “it will also open up this massive set of opportunities on 5G in the Internet of Things space, where you can connect everything that can be connected,” Neville Ray, T-Mobile’s chief technology officer and executive vice president, said on the company’s Q4 2017 call in February.
And the phone company plans to be aggressive. John Legere, T-Mobile’s CEO, said that 5G, when fully deployed, “will be in every spectrum band, and we will be participating in a lot of ways either through acquisition of spectrum, acquisition of companies, mergers and consolidation.”
But T-Mobile’s focus on the wide-area benefits of the 600 MHz band for its 5G rollout underscores a critical factor in the rollout of 5G: Not all spectrum is created equal. Millimeter wave signals don’t propagate well over long distances, have difficulty in the presence of trees and buildings, and require almost perfect line of sight.
“They hardly like air,” Robert Howald, Comcast’s VP of network architecture, said at an industry event last year. He was making a joke, but he also makes an important point — it’s unlikely that any 5G strategy will be able to live successfully on millimeter wave spectrum alone.
There is much to be worked out, but 5G is poised to be a gamechanger for anything streamed or downloaded.
