Professor Simon Saunders, Director of Technology, Real Wireless, Chair, Spectrum Applications & Demand, UK Spectrum Policy Forum and Adjunct Professor, Trinity College Dublin, is speaking at the LTE World Summit, taking place at the on the 23rd-26th June 2014, at the Amsterdam RAI, Netherlands. Book your last minute place now to hear about key issues such spectrum challenges.
Is shared spectrum a magic bullet for capacity crunch issues?
No. While an increase in spectrum sharing is inevitable over time, the devil is in the detail of the sharing conditions. If there is a lack of certainty, or onerous coexistence conditions, we have shown that the economic value of shared spectrum drops very rapidly compared with exclusive licenced spectrum. Given a choice, who wouldn’t prefer 50 MHz of exclusive spectrum over 100 MHz of shared spectrum with uncertain conditions?
Could LTE in unlicensed spectrum and small cells be a way forward to solve capacity crunch concerns?
Yes—these aren’t really different initiatives, but two ways to use more spectrum, more densely, to meet demand. But these aren’t really alternatives to additional licences spectrum: we’ve shown in several projects that the most cost-effective way to meet demand growth is to make simultaneous advances in technology, spectrum and network densification.
What are the latest developments in the use of white spaces for spectrum?
‘White spaces’ is really a first instance of a broader dynamic spectrum access approach, which seeks to make the best use of underused spectrum. Although most of the focus has been on TV and white spaces, the bigger impact is likely to come in other bands.
Can more be done to encourage spectrum harmonisation for today’s networks?
More harmonisation is always welcome, but the challenges come from real regional differences in the existing use of spectrum, which aren’t easy to overcome. That said, we see encouraging signs that bands such as 3.5GHz and 700MHz are looking increasingly like global ‘common denominator’ bands.
Could we see further release of spectrum in the UK in the near future years for data use?
Several further releases are already planned, including 700MHz, 2.3GHz and 3.4GHz. Beyond that much will depend on the outcome of the World Radio Conference next year.
Why is important for Real Wireless to be represented at the LTE World Summit?
We are providing impartial technology strategy advice to operators, regulators and vendors, while ‘bridging the wireless gap’ to big wireless users like stadiums, railways and governments. LTE World Summit is a great environment to keep our knowledge up to date and to spread the best practice that we have learned through existing assignments.
