Today, 4G or 5G networks are the two most commonly used. In a paper published in Nature in August 2025, however, scientists say they created a 6G chip that could be significantly faster than 5G. According to the study authors, the frequency range of this 6G chip spans over 100 GHz, which is "unprecedented." The scientists reported that the 6G chip could reach 100 Gbps, meaning it could be close to 500 times as fast as 5G. However, it's still a ways away, with some telecommunications experts telling CNBC that they don't anticipate 6G networks to go online until 2030 at the earliest.
