Nokia and AT&T collaborating to improve 5G uplink with distributed massive MIMO
The direction of our mobile network traffic is changing. Consumers are increasingly becoming content creators as well as content consumers, and many of the applications in the industrial internet of things require higher capacity on the uplink. AT&T and Nokia Bell Labs both recognize that greater uplink capacity will be of paramount importance in the 5G-Advanced era. To that end, AT&T and Nokia Bell Labs are working together to test a new proof-of-concept technology called distributed massive MIMO that will substantially boost uplink speeds and capacity without sacrificing downlink performance.

Bell Labs: The MIMO innovator
Bell Labs has always been on the forefront of MIMO innovation. Bell Labs researcher Gerard Foschini, who is considered one of the key inventers of MIMO technology, laid its foundation in the early 1990s when Bell Labs was part of the AT&T system. The principles of massive MIMO – one of the key technologies of 5G – emerged from Bell Labs in late 2000s. Today Nokia Bell Labs researchers continue to build upon those foundation. Researchers are finding new ways to enhance massive MIMO’s capabilities while also applying MIMO to new technologies like fiber transmission.
