Everyone knows 5G is coming. And 2019 is going to be the year of 5G—at least, that’s what the mobile industry keeps saying. We’re going to see the launch of several 5G smartphones from OEMs like Samsung, Motorola, and Huawei, and carriers will be tripping over themselves to tell you how awesome their new 5G networks are. Faster mobile network is coming, but should you care about it yet?

What is 5G

5G is shorthand for the “fifth generation of cellular network technology.” This fifth generation sees the introduction of mmWave (short for “millimeter wavelength”) technology, which taps into a broad range of radio frequencies in the electromagnetic spectrum that is currently unused—specifically the 24GHz to 90GHz range (current 4G LTE networks cover the 450MHz to 5.9GHz range).

What does this mean? Basically, much faster mobile networks and lower latency. While there are some big, bold claims being bandied about by tech companies (and conspiracy theorists) that build upon the potential that faster networks could bring, until we actually see how 5G implementation is utilized, much of this is just speculation. Besides, most of these companies are ignoring or intentionally obfuscating the current downsides of 5G.

The Downsides of 5G

We’re used to these “G” network upgrades coming with a compelling sales pitch about how much better everything is going to be, but the move to 5G mmWave is not a slam-dunk argument. Since mmWave runs at a significantly higher frequency than LTE, that means it comes with no shortage of tradeoffs. MmWave has worse range and worse penetration compared to LTE. A mmWave signal can be blocked by buildings, trees, and even your hand. MmWave doesn’t work well in the rain or fog, and the ~60GHz chunk of this spectrum can actually be absorbed by oxygen. That’s right—a slice of mmWave spectrum can be blocked by the air.

With so many issues to overcome, mmWave sounds like a terrible chunk of spectrum to build a mobile network in until you consider two key points: the higher-frequency means mmWave has plenty of bandwidth and low latency if you can get it, and most of all, the spectrum is available. MmWave isn’t being used for much right now because it is such a pain in the butt to work with. So if you can figure out all the implementation problems, you suddenly have a vast amount of airspace to work with. That’s actually the first thing these companies talk about when they bring up mmWave. It’s all going to be really, really hard and complicated, they say, but it’s going to be worth it.

LTE debuted in 2011, and these past seven years have seen significant progress in making 4G smartphone hardware smaller, faster, and more efficient. With 5G, we’re going to lose plenty of this technical maturity initially by packing in tons of new and expensive 5G hardware.

Buying a 5G phone in 2019

Smartphones today are almost entirely powered by a single chip, appropriately called an “SoC” or “System on a Chip.” As the name suggests, these are the most basic parts you need to make a computer all on a single, tiny chip. There are usually lots of CPU cores, a GPU, an “ISP” for camera functionality, Wi-Fi, and more. RAM isn’t technically included on this chip, but to save space, the RAM actually gets stacked on top of the SoC. The main off-SoC component is the storage, and across the motherboard there will typically be a sprinkling of tiny chips for power management, audio, Bluetooth, NFC, and other things. From there, it’s the motherboard’s job to connect everything to everything else and then get the hell out of the way so that as much as the phone as possible can be filled with battery.

Let’s compare the internal components you’ll need to make 4G and 5G work. In terms of major Qualcomm chips, a 2019 4G phone will have the Snapdragon 855, and that’s it. There’s an onboard LTE modem in the 855, so you don’t need an extra chip for connectivity, and LTE antennas are tiny wires that are usually integrated into the motherboard. 5G is a totally different story: you’ll need the Snapdragon 855, plus the Snapdragon X50 5G modem, plus a series of “QTM052” 5G antenna modules, which are actual chips instead of wires or motherboard traces.

It turns out Qualcomm’s first-gen 5G chips are going to be really big—at least, “really big” compared all the other extremely-small smartphone components. The X50 5G modem and a single RF module take up more space than the Snapdragon 855. Keep in mind the 855 is an entire SoC—nearly everything you need to run a computer—plus a built-in 4G modem, so it’s pretty incredible that a 5G modem and a single RF module takes up just as much space as the entire rest of the core phone components, minus the storage chip. For now, 4G has a clean, single chip design, while 5G is going to have these massive extra chips to deal with.
