Engineers from China and the USA demonstrated an ultra-fast 6G chip

The 6G chip can provide internet speeds of over 100 gigabits per second. This is 10 times faster than the theoretical maximum of 5G and nearly 500 times faster than the average 5G speed.

Prototypes with similar speeds have appeared before, but they were less efficient than the new chip. It was developed by scientists from Peking University, Hong Kong City University, and the University of California, Santa Barbara, reports ScienceAlert.

The chip is very small — only 11 mm by 1.7 mm, but operates in an "ultra-wide" frequency range from 0.5 GHz to 115 GHz. Covering such a spectrum requires nine different radio bands, which usually necessitates more complex components.

As the researchers explain, "ultra-wideband" is achieved using an electro-optic modulator that converts radio signals into optical signals. For the reverse conversion, the chip uses optoelectronic oscillations to generate radio frequencies across a broad range. This allows the chip to reach speeds of over 100 Gbps. For comparison, 5G is theoretically capable of speeds up to 10 Gbps, but in practice, it is much slower: in the USA, the average 5G speed is usually 150–300 Mbps.

Although companies still have a lot of work to do to develop infrastructure, 6G is almost inevitable and is expected to appear within the next decade. It will help cope with the constantly growing demand for data, especially through high-resolution streaming and active use of artificial intelligence.

In Japan, rare crested ibises, which had become extinct in the country several decades ago, have been reintroduced into the wild

For the first time in several decades, eight crested ibises – a species that became extinct in Japan in the last century – have been released into the wild.
