What’s the Difference Between 4G LTE and 5G Mobile Networks?

Marie Flanagan By Marie Flanagan November 4, 2021

Summary: It seems like everyone is talking about 5G — maybe because it promises to deliver speeds far faster than 4G LTE, and change our lives (again). Learn how the two networks relate to one another and why 5G will differ depending on where you live.

If you’ve bought any new device recently, you’ve probably heard “5G capable!” as a selling point. But what does that actually mean? And is it something you really need to be thinking about? For that matter, what was wrong with 4G?

If you’re not clear on the differences between 4G and 5G — or how much of a difference it will actually make in your everyday life — let’s break it down for you. (Hint: the G stands for generation.)

What is 4G?

4G became available during the early 2010s and replaced its predecessor, 3G, with speeds that were up to 10 times faster. If 4G speeds now seem blah, just think back to 2008 and remember how long you had to wait to load anything on your phone — if your phone had internet capabilities at all! Those days were all texting your updates to Twitter and asking ChaCha because you couldn’t talk to Google.

Feels like a lifetime ago, doesn’t it?

A graphic that shows the different wavelengths of 5G networks: low-band, mid-band, and high-band. Low-band can travel the farthest of the three. While it's the slowest 5G option, it's still faster than 4G. Mid-band is the sweet spot between speed and coverage. A limited number of cell phone carriers are currently able to use this type (and EarthLink Mobile is one of them.) High-band offers the fastest 5G seeds but can't travel very far. It's best suited for covering a small area. This is also known as millimeter wave (mmWave) 5G.

4G speeds have paved the way for apps that require rapid, real-time data transfers like high-quality video calls and rideshare services. You may have also heard 4G referred to as 4G LTE in recent years. The LTE stands for “long-term evolution” and it’s the specific type of 4G that can deliver the fastest speeds and is used by just about every smart device these days. So, if LTE is so great, why is the tech world excited about upgrading to 5G?

What is 5G?

5G is – you guessed it – the fifth generation of mobile technology. Just like 4G evolved into 4G LTE, 5G also has different bands that deliver a variety of speeds: low-band, mid-band, and high-band. Each type has unique benefits and can be used for different purposes.

  • Low-band: can travel the farthest of the three. While it’s the slowest 5G option, it’s still faster than 4G.
  • Mid-band: is the sweet spot between speed and coverage. A limited number of cell phone carriers are currently able to use this type (and EarthLink Mobile is one of them).
  • High-band: offers the fastest 5G speeds but can’t travel very far. It’s best suited for covering a small area. This is also known as millimeter wave (mmWave) 5G.

In addition to increased speeds, 5G promises reduced latency making it ideal for gaming, streaming, virtual reality, self-driving cars, and more. Latency is the delay between your physical action and the action on the screen — the lower it is, the better.

How Much Faster is 5G than 4G?

So just how much faster is 5G, really? Let’s put it this way: while 4G wireless networks typically offer 30 Mbps on a mobile device, 5G boasts speeds anywhere from 60 Mbps to 1,000 Mbps (aka 1 Gbps) depending on where you are.

Smaller towns and less densely populated areas will probably be using low-band 5G, so speeds will only be slightly faster than 4G LTE. In urban areas where high-band 5G is available, users will see speeds more than ten times faster than 4G.

High-band 5G is so much faster because those frequencies haven’t been used in the past, so there’s literally more room for everyone on the network. While mmWave 5G isn’t widely available yet, that could change over the next few years as technology and infrastructure continue to evolve.

Why are 5G Networks Necessary?

Sure, we’re all online more than ever these days, but why are 5G networks actually necessary?

It’s not just for the increased speed.

As we’re consuming more data every year, existing 4G networks are becoming more congested. This translates to a reduction in speed for everyone on the network and breakdowns in service. Just like fiber internet can handle tons of devices better than cable, 5G can handle thousands of devices at a time without service gaps, something 4G just isn’t capable of. If you’ve ever noticed you couldn’t easily use your phone in a stadium where, ahem, everyone else is also on their phone, that’s likely due to network congestion. An ad that says: Say Hello to EarthLink Mobile.

5G opens the door to more interactive experiences in stadiums, whether for sporting events or concerts. But it also allows for the possibility of autonomous cars reading maps and traffic patterns in real time, more advanced smart homes, advanced telehealth, and even remote surgeries. But what 5G is really doing is paving the way for advances we can’t even imagine yet. Just like we couldn’t have predicted real-time location sharing when 4G was first being built, we’re not sure what all 5G holds in store for us. But we’re excited to see where it leads.

If you’re ready to be on the cutting edge, switch to a mobile provider with 5G (and make sure your phone is compatible, too). Even if 5G isn’t available in your neighborhood yet, it will bring a better connection when it arrives. And in the meantime, be sure to have a mobile plan that fits your needs.
