BT has announced that it has tested a new quantum radio technology that will potentially improve the performance of our 5G networks.
Atomic radio frequency (RF) receiver technology uses so-called “excited atoms” to provide greater sensitivity than traditional radio equipment, allowing much weaker signals to be detected. Theoretically, this can increase the sensitivity by more than 100 times.
This means that it has the potential to reduce the power consumption of the mobile network, which will have a positive impact on low-power devices that make up the Internet of Things, which usually have to work for a long time with limited battery capacity. .
The receiver can be placed in a passive optical receiver in hard-to-reach places, which can have positive benefits for rural areas and other regions that find it difficult to receive a 5G signal. This could be a life-saving technology as the UK aims to reach that magical milestone of 100% 5G coverage.
The BT test, conducted at BT Labs in Martlesham, represents the first time a message has been received in digital code on the 3.6 GHz (5G) frequency. This is within one of the major commercial 5G EE frequency bands.
The next step is to miniaturize BT quantum radio equipment and optimize the use of signal processing for future 5G (and beyond) radio networks.
“BT’s investment in cutting-edge research and development is central to ensuring the UK remains at the forefront of networking,” said BT CTO Howard Watson. “Our program has huge potential to improve the performance of our next generation EE network and deliver even better services to our customers.”
