Introducing the New 5G Technology – Since 2019, the 5G network has been established in several U.S. regions. More and more companies and people have also started to use this latest generation of network in 2020.
5G network is a mobile connectivity network that offers a much faster data transfer than the previous generations. Because it has a high speed, We can also expect 5G to carry larger data. To be able to connect the world faster and easier. Intrigued? Read on to find out the in and out of 5G below.
We can see 5G in three different spectrums namely low band, mid-band, and high band. In low bands, it offers connections over large area but can only reach the maximum data speed of 100Mbps. While for mid-band, the speed can reach 1Gbps.
The high-band of 5G puts in another whole new level than the previous generations. Reaching a record-breaking level of datra transfer up to 10 Gbps. The caveat is this 5G area coverage is not broad at all. And of course, as we all know, maximum speed does not mean actual speed. Even though the maximum speed is 10 Gbps, the actual download speed will be around 100Mbps and upload speeds around 50Mbps.
Experts believe that 5G will greatly improve the application of Internet of Things (IoT) technology in various fields in the world. IoT is a connected-assets network. It also has the ability to transfer data over a network without the need for human-computer interface. IoT is useful for tracking manufacturing, logistics, smart cities, smart buildings to agriculture. You can read more about IoT here.
According to the GSMA, 5G will reach as many as 1.2 billion connections in 2025. They also predict that the 5G technology can cover one-third of the world’s population. Technology conglomerate like Samsung have produced mobile phones capable of serving the 5G network in some. Besides the US, other countries like South Korea, Japan, China, have provided commercial 5G networks.
Although the presence of 5G technology as the successor to 4G LTE has been growing, many questions remain about this latest technology.
Strengths and Weaknesses of 5G Networks
5G technology offers many benefit to people from various walks of life: students, professionals (doctors, teachers, engineers, government etc). Some of the advantages of 5G technology are:
The advantages of 5G technology
There are several advantages of 5G technology which we have summarized below as below:
- The resolution is high and has a large and bi-directional bandwidth.
- More effective and efficient.
- Most likely, it can provide additional large broadcast data (in Gigabit), which can sustain more than 60,000 connections.
- Easy to manage even with previous generations.
- Sound technology to support heterogeneous facilities (including private networks).
- Able to provide uniform, uninterrupted data
When coupled wit IoT, some other benefits for the general public:
- You can control your PC via a smartphone.
- Virtual class-room
- Remote medical treatment by medical professionals
- Smart city. Monitoring of street to fight crime
- Disaster prevention. Possible to accurately predict natural disasters such as tsunamis, earthquakes, and other natural disasters quickly.
The uncertainty around 5G Technology
Like a double-edged sword, technology does not only have advantages but also disadvantages. 5G technology included. Due to security issues and the lack of technological advancements in some part of the world, it presents several loopholes. Below are a few examples:
- The promised speed of this technology is difficult to achieve with low infrastructure
- Requires a lot of cost and time for the infrastructure development process.
- New 5G mobile devices are expensive
- Concerns about privacy and security issues remain unresolved for IoT applications
Is 5G Technology dangerous?
Some users have raised concerns about the potential health hazards that 5G technology will cause. The thing that is very worrying is the use of 5G millimeter energy waves which can cause higher radiation.
As we know, the radiation of radio signals that are emitted can have adverse effects on our bodies such as cancer. In 2011 the World Health Organization (WHO) report mentioned that cell phone radiation should be registered as a source of dangerous carcinogens for humans.
When in 2018, the National Toxicology Program released a 10-year study that found some evidence that there was an increase in brain tumors and adrenal glands in male rats that were exposed to RF radiation emitted by 2G and 3G cellphones, but did not occur in female mice.
However, allegations that cell phone radiation can cause cancer may be excessive. Because there are still many other things that are around us also have carcinogenic dangers. Some time ago, FCC Chairman Ajit Pai mentioned that the existing cell phone, including 5G, is safe and very ready to use.
Every technological advance must have advantages and disadvantages and their respective impacts. As users, it helps us to keep abreast of technological advancements while still paying attention to the problems that can occur from these technologies. Regardless of the two sides of the coin, we should remain cautious. One best way for us to keep well is to use all technology in moderation.
