A team of 5G engineers from the Universities of Bristol and Lund has once again set a new world record for wireless spectrum efficiency, less than two months after setting the first one.

In an experiment last week [Wednesday 11 May] using 128 base station antennas, the research group managed to serve 22 users, each modulated with 256-QAM, on the same time-frequency resource.  With an identical frame structure they used in the previous experiment, this would equate to a rate of 145.6 bits/s/Hz on a single 20 MHz radio channel.

The Communication Systems and Networks Research Group was formed in 1985 to address the research demands of the fixed and wireless communications sectors.  It combines fundamental academic research with a strong level of industrial application. The Group has well-equipped laboratories with state-of-the-art test and measurement equipment and first-class computational facilities. The Group is particularly well known for its pioneering work in topics such as antennas & propagation (multi-element channel sounders and ray-based propagation models), digital healthcare and connected and autonomous vehicles. Our leading research addresses topics such as the Internet of Things (IoT), autonomous vehicles small-cell mmWave communications (backhaul & access), software-defined networks and the wireless/optical interface. These technologies are critical in the development of efficient and cost-effective 5G networks.

Researchers of the CSN Research Group are members of the the Smart Internet Lab. This is a new initiative aiming at building on strategic and applied research on key communications and digital technologies at Bristol, to create and permanently support, a hub for Internet Research with long lasting benefits for society and economy.
