Explanation of 5G And What Future Smartphones, Connected Devices, and
Carrier Plans Are Going To Offer:  Rita's iDevice Advice for August 19, 2019

5G future 

Most technologies don't really require you to understand them to appreciate
what they can do for you. With 5G, however, things are going to be a little
different. To be clear, you don't need to know the details of how 5G works
to enjoy the potential speed increases and other cool capabilities it
eventually will offer. However, you do need to be aware of some 5G basics to
really understand what future smartphones, connected devices, and carrier
plans are going to offer - and how they'll differ. Learning a bit about how
5G works - and why not all 5G is the same - also helps to put some big
recent business developments into context. Specifically, the key reasons
Apple just spent $1 billion to purchase Intel's modem business and why
wireless spectrum issues were one of the key reasons the merger between
Sprint and T-Mobile was just approved by the Department of Justice make much
more sense once you understand the technology. First, some fundamentals. The
basics Like all cellular networks, the newly launched 5G networks use analog
radio signals at various frequencies to transmit data and voice signals from
cell towers or other transmitters to your phone or any other broadband
wireless connected device. A component called a modem, that's built into all
these devices, receives the signal via integrated antennas and other
elements, and converts that signal into digital form. Conversely, when you
send a text, browse a web site, make a voice call, etc., the modem takes the
digital signal from inside your device, converts it to analog form, and then
sends it via your device's antennas back out to the network. In other words,
modems are absolutely essential devices for smartphones and other devices
and that's why Apple chose to purchase Intel's 5G modem business. One of the
primary differences with 5G is the frequencies that are used to transmit
those signals to and from the cellular networks. While all existing 3G and
4G phones in the US use frequencies that are below 3GHz, most of the action
in 5G will be at higher frequencies. This is critically important because
radio signals at different frequencies function in very different ways. As
you may recall from your high school science classes (ahem), higher
frequency signals don't travel as far as lower-frequency ones. Think about
listening to a concert or other music source off in the distance. You only
hear the lower bass tones, not the higher ones. One of the primary reasons
this occurs is higher frequencies have shorter wavelengths than lower
frequencies. Why shorter is better A key benefit of these shorter
wavelengths on cellular networks is the ability to transfer data at faster
rates - in the case of certain 5G frequencies as much as 60 times as fast as
the average rate that current 4G LTE networks have across the US.

Should you buy 5G devices then? As you can see, there's a lot to know about
5G but now that you have a better understanding of the technology behind it,
you can see why it makes more sense to wait until second-generation devices
come around before you jump in. One more important point to make, however,
is that, unlike previous cellular network transitions, 5G won't completely
replace 4G. It will, instead, work on top of and alongside it. In fact, one
of the least appreciated benefits of the move to 5G is that it's making all
of our 4G networks better. As part of the process of installing 5G-capable
equipment into their networks, the big carriers also are upgrading their
existing 4G LTE equipment to take advantage of a development known as LTE
Advanced (which AT&T confusingly calls 5Ge). Many newer smartphones already
have 4G LTE Advanced-capable modems built in, so in many areas of the
country, it's already possible to get download speeds of up to 150 Mbps,
which is five times as fast as the national average. This is one of the many
reasons 4G networks and 4G devices will continue to be useful for many more
years.
