There has been a buzz surrounding Fifth Generation (5G) wireless networks for many years; but in 2019, cellular companies finally started widespread deployment. 5G technologies promise to change the way people communicate online with blazingly fast speeds connecting billions of Internet of Things (IoT) devices, which will help shape truly ubiquitous computing in the future. Users will be able to download entire films instantly, stream 4K video games flawlessly with decreased latency, accomplish astronomical computing tasks thanks to split rendering, and much more. In this webinar: • Learn what a 5G network is and what it is capable of doing, • Explore 5G standards and see how the technology will impact current library IT infrastructure, • Understand the issues concerning people’s anxiety regarding its safety, and • Discuss 5G’s future and how it will affect libraries. The webinar video and audio can be accessed at https://floridalibrarywebinars.org/understanding-5g-wireless-networks/. Original broadcast June 17, 2020.

3. What is 5G?
5G, the 5th generation mobile
network, delivers higher multi-
Gbps peak data speeds, ultra
low latency, more reliability,
massive network capacity,
increased availability, and a
more uniform user experience
to more users.

IMT-2020 (International Mobile Telecommunications-2020 Standard)
Requirements issued by the ITU Radiocommunication Sector (ITU-R) of the International
Telecommunication Union (ITU) in 2015 for 5G networks, devices, and services. The
following parameters are the requirements for IMT-2020:

If you listen to 88.5FM WMNF
community radio, then that radio
station is broadcasting an FM
radio signal at a frequency of
88.5 megahertz ("millions of
cycles per second").
The transmitter at the radio
station is oscillating at a
frequency of 88,500,000 cycles
per second.
Your FM (frequency modulated)
radio can tune in to that specific
frequency and give you clear
reception of that station.

This low-frequency repeats slowly.
This high-frequency repeats quickly.
[“The high frequency wave
needs much more energy to
travel the same distance.
On the other hand, in the
space it takes for three
pieces of data in the first
wave, you can fit 10 in the
second, so you can pack
more information into high-
frequencies, in the same
amount of time.”]

36. Is 5G Safe?

● Radiation is "emitting energy in the form of waves or particles." Phones "radiate" radio waves the
same way a speaker radiates sound, or a fireplace radiates warmth. That's all "radiation" means to
a scientist.
● We will probably never see a reputable study that unequivocally declares "cell phones are safe".
That is not how serious scientifc research works.
● Radio waves are below visible light on the spectrum, along with infrared light. This is the safe — or
non-ionizing — side of the spectrum, where frequencies — and thus energy levels — are too low
to knock electrons out of atoms.
● The RF waves given off by cell phones don’t have enough energy to damage DNA directly or to
heat body tissues. Because of this, it’s not clear how cell phones might be able to cause cancer.
Most studies done in the lab have supported the idea that RF waves do not cause DNA damage.
(ACS)
● Phones use many sophisticated technologies to make sure they're outputting the absolute
minimum amount of radio energy at any given moment, simply to conserve battery life.
