Technology for Radio Coexistence

Brought to you by The Radio Technology Group

Much needs to be done to improve the way that politicians, regulators, users and suppliers interact during the process of spectrum reallocation. This FREE Cambridge Wireless and ICT KTN event will explore some of the technological issues and possibilities in improving radio coexistence

Registration for this event is now closed.

About the event

Much needs to be done to improve the way that politicians, regulators, users and suppliers interact during the process of spectrum reallocation but in addition, RF technology itself needs to recognise that criteria such as link budget, coverage, and spectrum efficiency are not sufficient, and new systems and standards will have to take much more care to cope with coexistence.
The ICT KTN / Cambridge Wireless event, The Future of Spectrum Usage in November 2012 highlighted the importance of radio spectrum to the economy and the difficulties which increasingly arise as spectrum is re-allocated to new services without proper consideration of the impact on existing users of adjacent bands
As wireless connections become more widespread, we are moving towards a world where every product of any complexity is likely to have a radio connection of some kind, usually to communicate with other products. Often as the radio systems are designed, little or no consideration is given to their impact on other systems or their vulnerability to interference.

What aspects have to be considered? Just as examples:

  • Even low-power “licence free” systems have to be designed considering their likely neighbours and making sure that they can cope with appropriate blocking signals;
  • New major standards developments such as LTE must give proper consideration to out-of-band emissions which can’t be filtered out by victim systems;
  • RF component and circuit techniques are needed that can implement highly linear processing at low power;
  • New technologies are needed for frequency selective filters of higher performance at low cost and small size;
  • The Internet has shown us how it is possible to make an all-purpose network that can efficiently route many different kinds of traffic ranging from high-bandwidth data in an office LAN to long-distance voice to IP TV. Is it feasible to design an “electromagnetic Ethernet” that can similarly carry many different traffic types over different ranges using a common protocol, to permit better spectrum sharing?
Is it possible to design systems that can re-use spectrum “invisibly” to primary users of a given band, for example using null-steering antennas? 
 
This event will explore these and other technical issues in support of the UK Spectrum Forum activity which the ICT KTN is configuring. Please book soon to guarantee your place and avoid disappointment.

Introduction to the Cambridge Wireless Radio Technology SIG from Gerald Miaille of CSR

13:10

Welcome from our joint organiser Stuart Revell of ICT KTN 13:

13:10

Coexistence – Bridging the Legal and Technological Divide; James Walsh, Partner at Eversheds

Coexistence not only requires technological solutions to overcome interference, it also requires suitable
legal solutions. This presentation will examine the regulatory background to spectrum use and management, and some of key areas where technology and law can collide on questions of coexistence.

13:40

Q&A

13:45

Making LTE a Good Neighbour; Tim Lunn, Managing Consultant at PA Technology

We look at the mechanisms that cause adjacent channel interference in OFDM systems, and examine some of the approaches that can be used to minimise the interference in practical LTE implementations.

14:05

Q&A

14:10

RF Filtering for Interference Mitigation in Frequency Adjacent Systems; Dr Christopher Mobbs, CTO, Filtronic Wireless

Increasing demands for spectrum required to support consumer needs for high speed data have resulted in frequency allocations which have minimal guard bands between widely different systems. Despite advances in active electronics and signal processing, analogue filtering is sometimes the only effective solution to prevent interference between these systems. New filter technologies make this a more realistic and cost effective approach than has traditionally been the case.

Q&A

Coffee/Tea & Networking

15:10

Low Power Market and Spectrum Challenges; John Greaves, Low Power Radio Association (LPRA) / Director of Orion Systems

This presentation will focus on the increasing use of the 900MHz spectrum, the increase in the utility of the nebulous phrase NFC and the increasing concerns with regard to interference especially in key markets such as Health Care, Automotive and Food Safety applications.

15:30

Q&A

15:35

An Overview of Co-existence for White Space Devices and DTT - the Present Challenges and the Future Potential; Phil Kesby, Technology Consultant, Arqiva

This presentation will outline the technical framework for the deployment of white space devices in UHF spectrum and provide an overview of potential applications presently being discussed in the wider industry. The presentation will provide an overview of the major parameters required for co-existence modelling, and show the findings of an Arqiva development white space device database which outlines the present spectrum availability for these devices in the UK. The presentation will further discuss how innovation could prove to be the key to further improving the availability of spectrum for white space devices primarily by improving the white space device air interface and DTT receiver design.

SIG Champions

Mark Beach - Professor of Radio Systems Engineering, University of Bristol (Communication Systems & Networks Research Group)

Mark Beach received his PhD for research addressing the application of Smart Antenna techniques to GPS from the University of Bristol in 1989, where he subsequently joined as a member of academic staff. He was promoted to Senior Lecturer in 1996, Reader in 1998 and Professor in 2003. He was Head of the Department of Electrical & Electronic Engineering from 2006 to 2010, then spearheaded Bristol’s hosting of the EPSRC Centre for Doctoral Training (CDT) in Communications. He is the Co-Director of this centre. He leads research in the field of enabling technologies for the delivery of 5G and beyond wireless connectivity; which includes the recent award of an EPSRC Prosperity Partnership in the field of Secure Wireless Agile Networks (SWAN). Mark’s current research activities are delivered through the Communication Systems and Networks Group, forming a key component within Bristol’s Smart Internet Lab. He has over 30 years of physical layer wireless research embracing the application of Spread Spectrum technology for cellular systems, adaptive or smart antenna for capacity and range extension in wireless networks, MIMO aided connectivity for through-put enhancement, experimental evaluation and optimization of Massive MIMO, Millimetre Wave technologies as well as flexible RF technologies for SDR modems.
