5G will drive the future evolution of the internet itself—Huawei
5G cellular infrastructure is planned to offer faster multi-Gbps broadband peak rates, ultra-low latency, better coverage, vast network power, improved connectivity, and a more reliable customer interface. Higher efficiency and performance enhancements empower new user experiences and connect new industries.
No one business or individual owns 5G, but within the mobile industry, there are many businesses that contribute to bringing 5G to existence. Qualcomm has been instrumental in inventing the many basic technologies that drive the industry forward and make up the next wireless standard, 5G.
5G is based on OFDM (Orthogonal frequency-division multiplexing), a method of modulating a digital signal across several different channels to reduce interference. 5G uses a 5G New Radio (NR) air interface alongside OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave.
As with 4G LTE, 5G OFDM operates on the same principles of mobile networking. The new 5G NR air interface can however further enhance OFDM to provide much higher flexibility and scalability. In a number of specific use scenarios that will offer additional 5G connectivity to more individuals and items.
By expanding the use of spectrum resources from sub-3 GHz used in 4 G to 100 GHz and beyond 5G will bring wider bandwidths. 5G can operate on both lower bands (e.g., sub-6 GHz) and mmWave (e.g., 24 GHz and up), bringing extreme capacity, multi-Gbps, and low latency.
There are several reasons that 5G will be better than 4G:
5G is a unified platform that is more capable than 4G.
While 4G LTE focused on delivering mobile broadband services much faster than 3G, 5G is designed to be a unified, more capable platform that not only elevates mobile broadband experiences but also supports new services like mission-critical communications and massive IoTs. 5G may also support natively all types of the spectrum (licensed, shared, unlicensed) and bands (low, medium, high); A wide range of deployment models (from traditional macro-cells to hotspots), and new ways of interconnecting (such as device-to-device and multi-hop mesh).
5G uses spectrum better than 4G.
5G also aims to make the most of every bit of spectrum across a wide range of regulatory paradigms and bands available — from low bands below 1 GHz to mid bands from 1 GHz to 6 GHz, to high bands known as millimeter wave (mmWave).
5G is faster than 4G.
5G can be substantially faster than 4 G, delivering peak data rates of up to 20 Gigabits per second (Gbps) and average data rates of 100 + Megabits per second (Mbps).
5G has more capacity than 4G.
5G is designed to help increase traffic capacity and network efficiency by 100x.
5G has lower latency than 4G.
5 G has significantly lower latency to provide more instant, real-time access: 10 times lower end-to-end latency to 1ms.
"This is a really big mistake," health and environmental activist Camilla Rees told FOX Business of 5G. Rees and Grassroots Environmental Education Associate Director Doug Wood are one of several individuals and organizations contesting the 5G technology over environmental and health concerns, They brought up a 2018 study conducted by the Department of Health and Human Services' National Toxicology Program that found "clear evidence" of cancer linked to cellphone radio-frequency. There are several studies that show tumors were found in the brains, hearts, and adrenal glands of male rats exposed to cellphone radio-frequency, and DNA damage in female rats, protestors fear this could reflect even on humans.
The environmentalists protesting 5G are concerned that these studies aren’t being considered and the movement toward 5G is going way too fast. Another major concern with 5G implementation is what is called 'antenna densification,' or the antennas that will have to be put up in neighborhoods across the country as part of 5G's complex architecture that implements antennas that are close to home and satellites in space. Besides higher frequency, the proximity of the antennas to populated areas is also a concern.
Some 5G conspiracy theorists also argue that the new network is generating radio-frequency radiation that can damage DNA and lead to cancer; causing oxidative damage that can cause premature aging; disrupting cell metabolism and potentially leading to other diseases by producing stress proteins.
Few myths about 5G are:
1) 5G is about making smartphones faster- 5G should be about 100 times faster than 4G networks, but it should have wide-ranging impacts on many other sectors. Once rolled out, the efficiency of IoT, self-driving cars, and robotics should be massively increased.
2) 5G will only have a real impact on the telecommunications industry-It is likely to infiltrate many other industries, such as entertainment and even agriculture. For example, G could be used to communicate almost instantaneously between different farming apparatuses. This will allow one operator to operate different things from tractors remotely to combine harvesters, and much more.
3) 5G will replace 4G- Yes in theory but not necessarily. If most analysts did believe it would be decades away before 4G got extinct. This is mainly because 5G requires the construction of new infrastructure which will take years to complete. 5G requires antenna clusters closer to users. Just yet, it is simply not cost-effective to abandon existing 4G networks altogether.
There needs to be awareness of 5G and researchers should work to solve the problems and we can all hope that technology works to improve our lives and contributes to human growth.
