  • Have you heard of 5G?

  • you know, the wireless network that everyone is talking about?

  • except you're like, "What is it exactly?"

  • Well, I'm here to set the record straight

  • with five facts about 5G!

  • Fact one: 5G means 5th generation wireless technology.

  • hmm so just as 3G brought email to our phones and 4G

  • allowed for things like rideshare apps and streaming video, 5G might one day

  • give us driverless cars or drones that control their own drones or something.

  • We don't know. But there are some things we do know which leads me to fact number 2:

  • Not all 5G is created equal. Now, imagine I'm inside a guitar.

  • Wireless networks are built using different frequencies of radio waves that do different things

  • think of it kind of like sound.

  • First, there's the high band or millimeter wave.

  • these cycle at a ridiculously high rate. They can transmit a lot of

  • information. But they don't go very far because they get absorbed easily.

  • Next is the mid band. Now, these waves can go a little farther but there's not a lot of

  • mid band available for 5G.

  • Finally, there's low band like the six hundred

  • megahertz frequency the T-Mobile built its nationwide 5G on.

  • So let's learn a little bit more about that signal. Which brings me to fact number 3:

  • 600 megahertz 5G can travel through walls and buildings.

  • Sort of like the way light

  • travels through glass.

  • You know how you can always hear that fat bass on your

  • neighbor's stereo but not the high notes?

  • It's because that lower frequency

  • doesn't get absorbed or scattered by obstacles the way high frequencies do.

  • Hey, turn that down!

  • Now why does this matter? Because if your wireless signal

  • doesn't travel through walls, it's not nearly as useful.

  • 00:01:54,820 --> 00:02:00,000 Now the other interesting thing about 600 megahertz 5G is fact number 4:

  • 600 megahertz 5G goes farther.

  • which is really important because well, America is really freaking big!

  • and you need a 5G signal that can travel

  • further and cover more Americans and more places instead of say just a few of

  • us living in big cities.

  • oh and guess what?

  • fact number five: T-Mobile is the first and only carrier with nationwide 5G

  • T-Mobile's nationwide 5G already covers 200 million people and counting and it's

  • in over 5,000 cities and towns right now.

  • That's a lot of access to 5G for a lot of Americans.

  • share this video if you think more people should have access to 5G
