Lost in Space: How secure is the Future of Mobile Positioning?

CTN Issue: February 2016

This month we feature Professor Todd Humphreys, an expert in the James Bond world of faking out GPS signaling, to tell us what the latest news is for the reliability of the GPS systems that have become increasingly important to our everyday lives. Will GPS become the next front in the war between the modern world and the hackers and terrorists who wish to disrupt it? If so it will be engineers and not super spies who will save the day. Read on at your own risk. Comments welcome as always.

Resurrection of 5G: In defense of Massive MIMO

CTN Issue: January 2016

After our doom laden "death of 5G" series we did get some letters. In particular, the good people of the MAMMOET project in Europe managed to hit several points at once. So to start 2016 on an upbeat (and goodness knows it needs one), we have a positive look at massive MIMO covering both the throughput and the implementation for sub 6GHz. We hope this makes you feel just a little bit better about wireless in 2016. Comments (even doom laden ones) continue to be welcome of course.

5G and the next Billion Mobile Users: A view from Africa

CTN Issue: December 2015

Continuing our occasional series on the role of 5G in the connection of the next billion wireless users we have invited Fisseha Mekuria from the CSIR Meraka Institute in South Africa to explain some of the issues surrounding next generation wireless in his part of the world. Fisseha worked for Ericsson in Europe and has collaborated with both Nokia and Huawei before taking on his current role. So he brings a unique, international perspective on our industry. In reading his article it struck me that 5G was in some danger of losing the next billion entirely because of a lack of affordable wireless access in its requirements.

Is Anyone Out There? 5G, Rural Coverage and the next 1 billion

CTN Issue: November 2015

Today, most telecom players are ramping up their activities on "5G"; and, as for previous generations of cellular systems, there is an ongoing vibrant discussion about its critical, most important services and use-cases. New 5G-capabilities include radically higher bandwidths and lower latencies which its designers hope will enable virtual-reality, tactile internet, and control of moving things in real time. The industry generally focuses on capacity as the most crucial issue. This is technically supported by proposals based on more spectrum and dense deployment of base stations. All of this is extremely challenging and will keep the industry busy for another decade.
