A trio of telecoms and equipment makers have conducted what is claimed to be the first indoor test with radio waves in the 4.8 GHz band of 6G wireless technology using artificial intelligence.
The test from NTT Docomo, Nokia and SK Telecom confirmed that communication speeds can be improved up to 18% compared to other traditional indoor methods.
Specifically, the AI-based baseband transmission and reception processing developed by Nokia for modulation schemes applied to a wireless interface. The reception process using AI does not use a known signal between the transmitter and the receiver, which is conventionally needed to estimate the propagation channel. Instead, AI realizes a series of reception processes from channel estimation to signal detection in one step.
Looking ahead
With continued upgrades, the companies expect the technology to optimize modulation and demodulation schemes for a variety of sectors. This will also improve communication quality across a range of wireless use cases.
The next steps include NTT Docomo continuing to test initiatives with major domestic and international vendors as well as international telecoms. The company said it will accelerate 6G R&D and contribute to the standardization and commercialization of the next generation cellular technology.
