BT tests 5G carrier aggregation with Nokia

by James E. Carroll

BT is testing the aggregation of four carrier components (4CC) in a 5G Standalone (SA) live network in collaboration with Nokia. 

BT’s Networks team have successfully combined four low-band and mid-band radio channels, (2.1, 2.6, 3.4, 3.6 GHz), using Nokia’s 5G Radio Access Network technology in EE’s live network spectrum.

The trial was conducted in two stages; it was first performed in BT’s Radio Lab in Bristol, and then moved outdoors, onto a radio mast at BT’s Adastral Park in Suffolk, where the team successfully achieved 4CC on 5G SA radiating in EE’s regular radio spectrum. Not only is it the first time in Europe that a network operator has achieved 4CC on 5G SA using commercial spectrum, but it is also the first time it has been achieved outside of a lab in Europe.

Greg McCall, Managing Director Service Platforms BT, commented: “Our trial with Nokia is another demonstration of building the most advanced network for our customers. 5G Standalone, coupled with edge compute, will unlock new opportunities for customers looking to develop new services. Furthermore, this technology showcases what’s possible for devices in the future in terms of supporting carrier aggregation, which is an important part of customer experience.”

BT conducts Open RAN trial with Nokia

Wednesday, January 26, 2022  BT, Nokia, O-RAN  

BT will install Nokia’s RAN Intelligent Controller (RIC) for Open RAN, across a number of sites, to optimise network performance for customers of its mobile network, EE. The Open RAN trial is taking place in the city of Hull. BT said it is supporting Open RAN, with its vendor partners, to ensure it becomes a viable, mature, scale option for network optimisation as soon as possible. In addition to this trial, BT will also open a dedicated Open...

BT trials new hyper-sensitive quantum radio receiver

Sunday, May 22, 2022  BT  

BT is testing a new hyper-sensitive quantum antenna technology uses ‘excited atoms’ to deliver over 100x greater sensitivity than traditional receivers.BT says Atomic Radio Frequency (RF) receiver technology represents a revolutionary new way of detecting radio waves that could find much weaker signals than conventional receivers. The receiver works by using a quantum effect called “electromagnetically induced transparency” to form a highly sensitive...
