They say 5G is going to completely change our lives – from as simple to gaming, to

This shift will be a once in a decade upgrade for our wireless systems.

Now, that all sounds great but what is it and when can I get it?

Well, there's a brand new, second generation, cellular module from the current leading chip

company, Qualcomm that boasts the almighty power of

Except, we all don't exactly have 5G phones yet, nor a 5G mobile network.

However, this might be the year all that changes.

If you're just being brought up to speed, 5G, is known as the fifth generation of wireless

Every time the technical rules that define the inner workings of cellular networks changes,

we get a new “generation,” or “G” of technology, meaning to reap the benefits

people have to buy whole new phones, and carriers will need to install new transmission equipment

When we got 1G it was for voice calls only, but then 2G gave us text messages, 3G added

that multimedia support that we can't imagine being without, like vidchats and faster speeds,

and now we have 4G – which has all the features of 3G BUT an added bump of speeds from 14

Now we have video chats in HD, HD mobile TV, and live streamed apps But this next one is

5G is anticipated to give users the fastest connectivity they've ever experienced.

Its thought to be so fast it'd compete with our current fibre optic cables we have in

our homes, and about ten to a hundred times faster than the phone you currently have in

But other than the major benefits of downloading “8K” videos in seconds, and using VR and

AR seamlessly (goodbye buffering)why does the world want data coming in so fast?

Well, 5G connectivity promises reduced latency, or lag time, to practically zero.

Meaning devices can communicate with each other in nearly real-time.

We're talking about major improvements in the responsiveness in devices that use sensors

to make important decisions; like self-driving cars that need to suddenly brake, or industrial

robots that can be sent to hazardous areas and be controlled remotely from anywhere in

the world or better yet, anything in the healthcare field.

From telemedicine, precision surgical robots, to remote surgery, or even virtual physical

Well, 5G systems will run on smaller what they call, cell sites, that divide their territory

Then, exchanges between cell sites and devices are made with encoded data,through radio waves,

called OFDM, . This encoding isn't much different from

what 4G LTE uses, but the frequencies they use within the spectrum are.

Right now the low-band spectrum that 4G LTE travels on is overly crowded and therefore

Which, by the way, doesn't seem too bad running on Verizon visible for only $40/month,

5G can currently travel on a couple of kind of airwaves.

One low-band frequency and one high-frequency.

The plans are for low-band frequency 5G to operate through 4G cell sites that companies

But the encoding will be more flexible and use a bigger channel size to get up to 50

But since we want the multi-gigabit, ultra-fast, speeds, we're going to use higher frequencies

Now it slightly varies, but millimeter waves are signals estimated to be above 24GHz or

30GHz range where there's enough spectrum available to create big channels for very

But what researchers have been struggling with is the fact that these wavelengths are

easily blocked and can only go very short distances.

That's why we have to get the small cell sites.Hundreds, if not thousands of lower-power

base stations (outputting only 2-10 watts each)will have to be built in and around city

There are select places around the U.S. that actually already have some of them, BUT we

still need our devices to upgrade to get the speeds we want.

This is where the Qualcomm chip comes in.

Qualcomm is a wireless chip maker and they've been the forefront of advancements in chip

Their new one, creatively called Snapdragon X55 5G , is a millimeter wave modem that would

run along their new millimeter wave antenna the QTM525..

The idea is that these modules will help smartphones connect to the new and improved network of

5G AS WELL AS stay connected to the previous “g's” 2 through 4.

They anticipate that phone makers will embed three or four modules in their devices, so

the device always gets a signal from one module even if the others are blocked by something

like your hand.And Qualcomm is not the only one, there are other brands that are in the

works to make 5G happen for the consumer market.

So, for us to really reap the benefits of this all-powerful 5G speed.

The whole infrastructure needs to change.

You can't have the 5G phone without the 5G network, and you can't have the 5G network

until you get the mini cell towers, but companies are making massive strides.

Most of the phones and networks are planning to launch at the end of 2019.

So keep your eyes peeled, And your phones ready to throw out
