The latest in the Telecoms Trailblazers series
Hello, I am David Grace, a research professor at the University of York in the School of Physics, Engineering and Technology. I am an electronic engineer by training, specialising in wireless communications for almost 30 years now.
I’m currently involved with the Yorkshire Open RAN (YO-RAN) initiative, part of DSIT’s FONRC competition. Several universities, suppliers and network operators have joined forces to develop Open RAN components and a RAN Intelligent Controller (RIC) for Neutral Host Networks. The project allows for the same infrastructure to be used by multiple operators, and also by private or enterprise-based networks.
My particular interest is researching how we can apply artificial intelligence to the RIC. Practical experiments, however, are equally as important. Testing out cutting-edge technologies and going beyond what a traditional academic might be expected to do is crucial. I want this work to have a concrete impact.
YO-RAN is only in its early stages but soon we will be testing out the Open RAN technology in our first medium-scale test, analysing how multiple base stations can interact in a small area, and looking at a brand new radio unit. Our second and third tests will cover larger areas, potentially between Sheffield and York, and also tests involving the Advanced Manufacturing Research Centre in the North West.
As for the next priority, making non-terrestrial networks, including aerial-platform-networks, Open RAN compliant is high on my agenda. Perhaps UKTIN has a role to play here.
1/ What do you enjoy most about working in this space?
The opportunities it brings. I have met so many interesting people and visited places I wouldn’t have had the chance to otherwise.
2/ What’s the most ridiculous thing you’ve done in the name of work?
Imagine being in a remote valley in North Yorkshire. I was participating in a 5G test, looking at how a mountain rescue team could use our portable 5G base station to help in a mock rescue. That was quite ridiculous, given the horrendous weather which was even challenging for the rescue team.
3/ What excites you most about working in telecoms?
The ability to connect people and systems. Also, providing connectivity where there isn’t any. That is incredibly exciting to me.
4/ What would you like people to know about your work?
I am very interested in real-world practical implementations. I guess beyond what you would normally see from a traditional academic.
5/ Why is a vibrant, flourishing telecoms ecosystem important for the UK?
Telecoms is an essential technology for all of us, and we need to be at the forefront of developing that technology. To do that, we must maintain our leadership and interest in the area.
