Innovations in wireless data transmission have reached a groundbreaking milestone, achieving speeds of 938 gigabits per second—over 9,000 times the average speed of current 5G mobile connections. This astonishing rate allows for the download of more than 20 average-length movies in just one second, marking a significant advancement in multiplex data transmission, where multiple signals are combined.
High demand for wireless signals during large events, such as concerts and sports games, often leads to mobile networks becoming overwhelmed. The constraints of current 5G technology, which typically operates within a limited bandwidth of frequencies—generally below 6 gigahertz—cannot meet the growing needs for faster and more reliable wireless communication.
Researchers at University College London have pioneered the use of a broader spectrum of frequencies, ranging from 5 gigahertz to 150 gigahertz, utilizing both radio waves and light. This innovative approach seeks to enhance transmission rates significantly.
According to the research team, traditional digital-to-analogue converters used for sending data struggle with higher frequencies. Their solution involved using conventional technology for lower frequencies and an advanced laser technique for the higher range, enabling the creation of a comprehensive bandwidth. This advancement is poised to be integrated into next-generation smartphones.
The result of their efforts allows data to be transmitted at an astonishing 938 Gb/s, vastly improving user experience by providing enhanced bandwidth for streaming and downloading content—especially in crowded environments.
While this multiplex speed record is remarkable, single signals have previously achieved rates exceeding 1 terabit per second. The innovative method of spreading signals across a wider frequency range effectively transforms the limited bandwidth of 5G networks into a more expansive and efficient system, akin to converting a narrow road into a multi-lane highway, facilitating increased traffic flow.
Conversations with smartphone manufacturers and network operators are ongoing, and there is optimism that this research will lay the foundation for future 6G technology, as numerous innovative approaches seek to redefine mobile connectivity.
