Places the fastest internet in the world - speeds you will never imagine!

ADVERTISEMENT

Internet speed varies from one place to another in the world, and in recent years we have seen experiments and networks with unprecedented speeds, although their geographical coverage is limited. For example, South Korea is known for having some of the fastest internet speeds in the world, with an average download speed of more than 52 Mbps. This is due to the huge investment in infrastructure and technology by the government and telecom companies. Higher speeds allow for faster connections, more efficient business processes, and greater access to online resources. As technology continues to evolve, we can expect internet speeds to increase even more, improving connectivity and driving innovation around the world.  In this article, we show you the most important places where the highest speeds have been observed so far.

Huawei Technologies and China Mobile have formed a project to build a 3,000-kilometer internet network connecting Beijing to the southern regions, using the latest available technologies. The companies said they teamed up with Tsinghua University and research firm Sernet.com to create a groundbreaking internet network that achieves "stable and reliable" connections at 1.2 terbits per second, much faster than current internet speeds worldwide. The university classified this project as the first of its kind, and confirmed that it relies entirely on local technology.

The new network spans more than 3,000 kilometers of fiber optics, connecting the cities of Beijing, Wuhan and Guangzhou. Thanks to its exceptional speed, this network can transfer 150 4K movies in less than a second, and move the entire global Netflix library in less than half an hour. The network is part of China's Future Internet Technology Infrastructure (FITI) project, a decade-long initiative and the latest iteration of the China Education and Research Network (Cernet). The head of the FITI project from the Chinese Academy of Engineering confirmed the successful operation of this high-speed line and the provision of advanced technology necessary to build a faster Internet in the future.

A team of researchers in Japan has achieved a new milestone by successfully transmitting data over a 3,000-kilometer fiber optic cable at an astonishing speed of about 319 terabytes per second. This rate is capable of transferring 10,000 high-definition movies, each about 4 GB in size, in just one second. However, this high-speed technology is mainly used in the core networks of broadband providers and is divided among many customers, making it unsuitable for normal home use. This achievement surpasses the previous record for long-distance data transmission of 172 terabytes per second, which was also achieved by researchers at the National Institute of Information and Communication Technology (NICT) in Tokyo. The researchers stated that the new system could work with existing infrastructure, making it easier to upgrade networks because the fiber optic cable used would not need to be changed in terms of length and size. They also highlighted the importance of this rapid transfer of basic infrastructure, as there is a growing need for services that require faster speeds than provided by fifth-generation networks, in addition to running devices and tools over the Internet, especially for live streaming activities.

In a major breakthrough that has the potential to transform communications, a team of researchers at Aston University in Britain, working in partnership with international collaborators, has achieved data transfer speeds 4.5 million times faster than a typical home broadband connection. This impressive 301 terabytes per second, equivalent to 301 million Mbps, sets a new standard for the fastest data transfer using a single standard fiber optic cable.

Professor Vladimir Fabry of the Aston Institute for Photovoltaic Technologies, as well as Dr Ian Phillips and a team from the National Institute of Information and Communication Technology (NICT) in Japan, and Nokia Bell Labs in the United States participated in the collaborative research. This achievement is important in meeting the growing global demand for data. Breakthrough in data transmission is made possible by taking advantage of previously unused wavelength bands within fiber optic systems.
