5G TECHNOLOGY: EVERYTHING YOU NEED TO KNOW

5g

When we talk about 5G what do you first think about? Well, a lot what is 5G? Is 5G better than 4G? Does using 5G harm us? How fast is 5G and many others?

5G is a basically 5th generation mobile network, as we had 4G as the fourth generation and 3G as the third generation. For 5G, you will see faster download and upload speeds and also the time it takes for devices to communicate with wireless networks, will also decrease drastically.

Overview

As with previous standards (4G 3G and the rest), the covered areas are divided into regions called cells which are serviced by individual antennas.  All the 5G wireless devices in a cell communicate by radio waves with a local antenna array and low power automated transceiver.

However, telecommunication service providers in the developed world especially are deploying antennas for 5G to make it accessible everywhere.

The frequency spectrum of 5G is divided into millimeter waves, mid-band, and low-band. Low-band uses a similar frequency range as the predecessor, 4G.

Millimeter-wave is the fastest, with actual speeds often being 1–2 Gbit/s. Frequencies are above 24 GHz reaching up to 72 GHz which is considered above the extremely high-frequency and might also be harmful. Millimeter waves have difficulty moving through many walls and windows, so indoor coverage is very limited.

Mid-band is the most widely deployed type of 5G network in over 20 networks. Speed is usually 100 – 400Mbit/s down and occasionally it can speed up to over a gigabit per second. Frequencies deployed are from 2.4 GHz to 4.2 GHz. Sprint is using 2.5 GHz, while others are mostly between 3.3 and 4.2 GHz, a range that offers increased reach.

Benefits

5G is a new kind off-network broadband that will not only enhance mobile broadband service but will also expand mobile networks to support a vast diversity of devices and services and connect new industries with improved performance and efficiency.

5G will also deliver a lower latency for a quicker and immediate response, and an overall more uniform user experience so that the data speed stays consistently high even when users are moving around.

A recent study showed that 5G’s full economic effect will be realized across the globe by 2035, supporting a wide range of industries and potentially producing up to $12 trillion worth of goods and services. Amazing right?

Speed

5G speeds will range from 50Mbit/s to over 2 gigabits at the start and it is expected to grow to even 100Gbit/s that is 100x faster than 4G. The fastest 5G, the Millimeter-wave, delivers a speed of up to and over 2Gbit/s. The problem with this though is that it cannot go through walls, trees, and other things because of its high frequency, meaning the connection is quite limited when you are indoor (just a wall can block all signals)

Also, Qualcomm Technology’s first 5G modem, Qualcomm Snapdragon™ X50 5G modem, is designed to achieve up to 5 gigabits/s in a downlink peak data rate.

The sub-6 GHz 5G a Mid-band 5G, by far the most commonly used type of 5G technology, it usually delivers speed between 100 and 400 Mbit/s but has a much farther reach than mmWave (Millimeter-wave), and is not being limited by walls, trees, and other obstacles which interfere with mmWave transmission.

Also, the Low-band spectrum offers the farthest area coverage but is the slowest among the 3 but it is still faster than 4G.

Dangers of 5G technology

The development of 5G technology has elicited a lot of concerns that 5G radiations could have a bad effect on our health. Many scientists around the world understand that the electromagnetic radiation leaking through the doors of our microwave ovens can cause cancer. Some also believe that this radiation can change the DNA structure of living beings.

Therefore 5g radiation will be like opening your microwave door and keeping it on for the rest of your life, imaging the kind off damage this can do. Also, some scientists also believe that 5G technology could cause infertility, autism, and Alzheimers.

In April of 2019, the city of Brussels in Belgium blocked a 5G trial because of radiation laws. Also, In Geneva, Switzerland, a planned upgrade to 5G was stopped for the same reason.

Here are a few things you could do to reduce 5G radiation:

  • Stop using your phone for long hours.
  • Do not live closer to a 5G poll or cell tower.
  • Spend a lot of time in places where there are a lot of trees.

Conclusion

5G might an evolution in modern technology but also in other minds is dangerous for every living being, but we hope it is not as bad as some of us might think.
