Samsung clocks world fastest’ 5G Speeds of 4.3 Gbps Using mmWave Technology
Imagine you sitting in your hall due to the lockdown imposed due to the COVID-19 pandemic. You are trying to watch your favorite movie/TV show, play an online game or video call a dear friend. Suddenly you find your Wi-Fi or mobile data collection has dropped to an abysmal speed. In a world where the average speed is about 3 Mbps, things like these happen every other day to us. However, now imagine you are on a 5G network and able to surf the Internet at a whopping speed of 4.3 gigabytes per second.
Yes, you heard it right. Samsung managed to clock this awe-inspiring speed in a 5G environment using a new technology called mmWave technology. This speed is 100x faster than the speed we are used to now baring a few souls who manage to surf at speeds of Gbs.
Samsung Electronics announced on Tuesday to have achieved “fastest” 5G speeds in its tests. Samsung used 5G to achieve 4.3Gbps speeds each on two test mobile devices, for a total of 8.5Gbps by running single Samsung 5G Millimetre-wave (mmWave) Access Unit. According to Samsung, they used MU-MIMO (Multi-User, Multiple-Input, Multiple-Output) technology on 800MHz of mmWave spectrum, along with carrier aggregation.
What is mmWave spectrum
mmWave spectrum is the band of the radio frequencies in the electromagnetic spectrum between 30GHz and 300GHz. quite similar to the spectrum bands we use now. However, this spectrum is used to provide only high-speed wireless communications while the other spectrums are used for 2G/3G/4G and other techs. The uniqueness of the spectrum makes it able to deliver fast 5G speed thereby delivering faster media and services. This band falls between microwave and infrared waves.
While India is yet to assign any spectrum for 5G technology, a few countries like the US, Japan, and South Korea have already assigned the superfast 5G mmWave spectrum for testing and commercial use. Many other countries including India are also expected to jump on the 5G mmWave by 2022.
“The wide bandwidth from mmWave spectrum enables mobile operators to provide multi-gigabit speeds that lower band spectrums are unable to match,” Samsung said. With multi-gigabit speeds, users can experience transformational 5G mobile services. Mobile operators will be able to deliver new and rich services such as 8K video streaming, AR remote learning and holistic VR teleconferencing as well as new use cases that are yet to be imagined.”.
Remember, Samsung achieved 4.3 Gbps in a controlled setting so commercial speeds could be limited to some sort of benchmarks but 5G watchers expect the tech to bring 2 Gbps speeds to ordinary users in due time.
Disadvantages of mmWave technology
Experts say that while the new mmWave technology is very impressive in terms of speed and response times, it is not very reliable. The mmWave technology is considerably weak over distances and has connectivity issues. Sometimes the waves are unable to cross walls near a short distance. It remains to be seen how much success the 5G mmWave technology will have in the future.
