5G Technology: Facts And Expectation
By Treasure Mayowa
5G is the future of wireless network technology. It will come to improve and transform the way we live and do things.
5G is the fifth generation of mobile network. It is the lastest standard after the 4G network. 5G is a unified, more capable air interface. It has been designed with a capacity to enable improved user experiences, bringing in new features.
5G is also known for its increased speed, which obviously, will surpass the rest.
Features of 5G
A lot of people have given different ideas on what 5G technology entails. Some of them:
- “With 5G, data transmitted over wireless broadband connections can travel at multigigabit speed”
- ”It offers extremely fast speeds as high as 2 gigabits per second (Gbps) by some estimates”
- “5G is more efficient with more available bandwidth and advanced antenna technology.”
- ”MM wave signals are easily blocked by trees, walls and buildings. They can only cover within a specific area. A 5G device will use an air interface using multiple nodes around each block.”
- ”It also includes enhanced mobile broadband for its user”
- ”It offers a more accurate location tracking”
- 5G enables new services. 4G can support up to 2 Gbps and is slowly continuing to improve in speeds. 4G featured speeds up to 500 times faster than 3G. 5G can be up to 100 times faster than 4G.
5G vs 4G
Unlike 4G networks, 5G has higher bandwidth and speed. The download speed of 5G is upwards of 1,000 megabits per second (Mbps) or even up to 2.1 (Gbps). With the emergence of 5G, one can watch a High Definition (HD) YouTube video without it buffering. Downloading an application, that would have taken some minutes, will probably take some seconds. One can video stream with efficiency and ease.
According to Techtarget; “One of the main differences between 4G and 5G is the level of latency, of which 5G will have much less. 5G will use orthogonal frequency-division multiplexing (OFDM) encoding, similar to 4G LTE. 4G, however, will use 20 MHz channels, bonded together at 160 MHz. 5G will be up to between 100 and 800 MHz channels, which requires larger blocks of airwaves than 4G”
Bigger and Better and even Bigger
Alongside improvements in speed, capacity, and latency, 5G offers network management features including network slicing enabling mobile operators to create multiple virtual networks within one single 5G network. This capability will enable network connections to support specific uses and could be sold on an as-a-service basis. For instance, a self-driving car would require a network slice that offers extremely fast, low-latency connections so the vehicle could navigate in real-time.
5G Myths Debunked
No 5G is not a military weapon, doesn’t release harmful radiation, and doesn’t aid the spread of COVID-19 as earlier assumed. The WHO has said the following to debunk all claims;
“To date, and after much research performed, no adverse health effect has been causally linked with exposure to wireless technologies. Health-related conclusions are drawn from studies performed across the entire radio spectrum and provided that the overall exposure remains below international guidelines, no consequences for public health are anticipated.”
There is currently no relation between the 5G network and COVID-19.
Networks operators in the United States, Japan, South Korea, and China have already taken a step towards 5G network development.
Network operators are expected to spend billions of dollars on 5G capital expenses through 2030, according to Technology Business Research (TBR) Inc., although it is not ascertained how 5G services will generate a return on that investment. Companies including Verizon Mobile, T-Mobile, AT&T, and Sprint.
Also, according to a 2019 Wall Street Journal report, Chinese companies Huawei and ZTE Corp have put forth vastly more proposals —and are among the biggest owners of key 5G patents.
In Nigeria, however, 5G is not yet available(as of the time of writing). Last year, the NCC gave permission for MTN to test the possibilities of 5G technology in three major cities; Lagos, Abuja, and Calabar.
A demo that was limited to their offices in those locations lasted for three months and has since been concluded. The NCC has confirmed that 5G spectrums (radio frequencies) are available to be distributed when the time is right.
Phone companies like Huawei and Samsung have gone ahead of their competitors in making their phones 5G enabled and 5G compatible. Some of them are:
- Samsung Galaxy S10 5G
- Samsung Galaxy Note10+ 5G
- Samsung Galaxy A90 5G
- Huawei Mate X
- Huawei Mate 30 Pro 5G
- OnePlus 7 Pro 5G
- Moto z3
- Xiaomi Mi MIX 3 5G
