Широко применяемые технологии, такие как 3G, 4G, LTE и Wi-Fi, обеспечивают связь между миллиардами устройств, однако с ростом цифровой нагрузки и числа подключений традиционные решения начинают сталкиваться с проблемами перегрузки и снижения пропускной способности. В ответ на эти вызовы развивается технология Li-Fi — Light Fidelity, основанная на использовании видимого света для передачи данных. В её основе лежит принцип Visible Light Communication (VLC), позволяющий светодиодным источникам света модулировать сигнал и передавать информацию на высоких скоростях. Целью этой работы является рассмотрение архитектуры и технических параметров Li-Fi и анализ её преимуществ и недостатков по сравнению с радиочастотными сетями. Методология исследования состоит в рассмотрении научной и технической литературы, обзоре стандарта IEEE 802.11bb и сравнении с имеющимся набором технологий беспроводной связи. Результатами исследования является, что Li-Fi имеет высокую скорость передачи данных, энергоэффективность и безопасность, но требует прямой видимости и пока ограничена в применении. На основе результатов можно сделать вывод о том, что Li-Fi представляет собой перспективное направление для развития устойчивой и высокопроизводительной сетевой инфраструктуры будущего.

With 5G, you can download data much faster even up to 10 Gbps with almost no delay. The goal of this research was to better understand how 5G technology can improve our daily lives and impact fields such as transport, healthcare, industry, and smart cities. The methodology included examining scientific articles, government reports, and examples from countries that have already implemented 5G. The main results showed that 5G offers very high internet speeds, low latency, and reliable support for simultaneous connection of multiple devices. These features make it perfect for smart homes, self-driving cars, remote medical services and other. Many people are concerned about potential health risks, but specialists have stated that it is harmless if safety standards are followed correctly. 5G is not only useful for phones and computers but also for smart systems in cities. For example, traffic lights, security cameras, and public transport can be connected and managed with less effort. In factories, machines can communicate with each other in real-time, improving production efficiency. In healthcare, doctors can do surgeries distantly using robots. In transport, self-driving cars can communicate quickly to avoid accidents and reduce traffic.

Building on 5G, 6G represents a major shift - not just in connection speed and latency, but in network intelligence, responsiveness, and user experience. Central to 6G is the integration of artificial intelligence and machine learning directly into network infrastructure, creating self-optimizing, adaptive systems capable of managing themselves in real time. Key technical advancements include data transfer speeds up to 100 times faster than 5G, sub-millisecond latency, and the use of Terahertz frequencies to handle massive data throughput.The article outlines several transformative applications, including autonomous vehicles, real-time urban monitoring in smart cities, remote health care, and intelligent factory automation. These use cases illustrate how 6G could impact both public infrastructure and private industry. Alongside these opportunities, the article addresses the major challenges facing 6G development. These include regulatory issues around spectrum allocation, increased power consumption, cybersecurity threats linked to AI systems, and the high cost of deploying new infrastructure. Finally, a phased roadmap is presented, showing the global timeline for research, prototyping, standard-setting, and deployment. The article concludes that 6G will not simply improve mobile communication, but fundamentally redefine how humans and machines interact in digital environments.

Unlike previous generations, 6G integrates artificial intelligence (AI) directly into the core of networks, offering ultra-high speeds up to 1 terabit per second and ultra-low latency of 0.1 milliseconds. This enables real-time applications such as remote surgeries and autonomous vehicle coordination. Key technologies include terahertz frequencies, quantum communication, and intelligent reflecting surfaces. Additionally, 6G will support massive connectivity, linking tens of millions of devices within a confined area. Practical applications target sectors like healthcare, industry, transportation, and daily communication, providing immersive experiences and enhanced security. Despite its revolutionary potential, 6G faces challenges related to infrastructure, energy efficiency, and regulatory frameworks. Global development is led by countries such as China, the USA, Europe, Japan, and South Korea. This technology promises to redefine human interaction with technology through intelligent, context-aware networks.
