We have a new book project under way with Artech House.

'5G spectrum and standards' analyses the spectrum, band plan and standards choices for 5G radio systems and the relative technology and economic impact of these choices on the industry supply chain, operator community and end users. It divides the spectrum into three blocks defined by wavelength rather than frequency – the metre band (300 MHz to 3 GHz), the centimetre band (3 GHz to 30 GHz), and the millimetre band (30 to 300 GHz). Present and future coexistence issues in these bands are analysed including mobile broadband coexistence with terrestrial broadcasting in the metre band, coexistence with  fixed point to point and satellite/mobile service satellite and radar in the centimetre band and co-existence with automotive radar and military sub space radio in the millimetre band. Case studies are included of existing local area Wi Fi ‘5G systems’ at 60 GHz (5mm wavelength) and used to highlight the wavelength and technology requirements needed to scale these local area systems to deliver economic wide area high data rate mobile and fixed access connectivity.
The present spectral allocation process is reviewed including the ITU and CEPT and how this process relates to spectrum auctions and regulatory policy and standards making across the traditionally separate industries of mobile broadband, terrestrial broadcasting, and military and consumer satellite and radar.
The outcomes of the two World Radio Congresses in 2012 and 2015 (WRC 2012 and WRC 2015 this November) are analysed together with the agreed agenda points for WRC 2019.
The present regulatory balance between sovereign responsibility and regional and global policy making is studied in the context of present and future social and economic change including the present balance between licensed, lightly licensed and unlicensed spectrum.
The final chapter argues the case for mixed use approaches to spectrum allocation (analogous to present satellite mixed payload platforms) with the potential to provide the basis of a new generation of collaborative mutual interest business models which could transform the delivery economics of the 5G mobile broadband sector.

New study for Ofcom on frequency band support in smart phones

Ofcom have published a study that RTT worked on last year with Aegis.

The report is based on a series of interviews with the industry supply chain and provides insight into the performance cost (range and energy consumption) and dollar cost of supporting additional non-standard frequency bands in HSPA and LTE smart phones.

LTE and the evolution to 4G wirelessLTE and the Evolution to 4G Wireless

A new and very excellent (second) edition of LTE and the Evolution to 4G Wireless is now available published by John Wiley and Agilent Technologies and edited by Moray Rumney.

This takes you through the practicalities of Release10 and Release 11 through 15 and includes useful insights on the test and measurement implications of each Release for conformance testing and manufacturing test – ideal reading for that holiday break that you are promising yourself.

Making Telecoms Work – from technical innovation to commercial success.

Available from the RTT bookshop

Bridging the industry divide between the technical expertise of engineers and the aims of market and business planners, Making Telecoms Work provides a basis for the interdisciplinary analysis of technology, engineering, market and business investment risk and opportunity.

Since mobile broadband has become a dominant deliverable, multiple areas of transition and transformation have occurred; the book places these changes in the context of the political, social and economic dynamics of global telecommunications.

Drawing on 25 years of participative experience in the mobile phone and telecommunications industry, the author closely analyses the materials, components and devices that have had a transformative impact.

By presenting detailed case studies of materials innovation, such as those shown at success story Apple, the book shows how the collaboration of technological imagination with business knowledge will shape the industry’s future.

  • Makes a link between the technical aspects and the business practice of the telecoms industry, highlighting the commercial and economic significance of new developments.
  • Gives a historical analysis of past successes and failures in order to identify future competitive advantage opportunities.
  • Supplies detailed case studies of supply chain disconnects and the impact these have on industry risk and profitability.
  • Brings together technological detail with analysis of what is and is not commercially important, from the implications of energy and environmental networks to the technical details of wireless network hardware.

Making Telecoms Work – from technical innovation to commercial success

A 30-fold increase in data traffic in the next five years is driving the move to LTE

Just one of the findings from RTT’s new study LTE User Equipment, network efficiency and value

The future of the mobile broadband industry is very much in the balance. On the basis of present traffic growth trends, mobile broadband data traffic will have increased from a present level of three exabytes to 90 exabytes by 2015 .An exabyte is equivalent to one million terabytes.

Over the same period revenue is projected to grow by a factor of 3.The projected efficiency savings from new technology such as LTE are insufficient to bridge this gap. New solutions to this dilemma are therefore required in order to enable the sustainable growth of the mobile broadband industry.

This study identifies crucial links between user equipment performance and network economics and argues the case for year-on-year improvements to be made to UE performance over and above the minimum conformance requirements. A business model is presented which shows that a small increase in UE cost has a positive return when measured across the mobile broadband ecosystem.

RF Design Programme

Extended Multi Band
Design and Testing LTE user equipment

A two day programme for engineers and team leaders involved in
UHF broadband multi band multi standard cellular transceiver
and integrated UHF (TV) receiver design.

The programme is also relevant to policy makers needing to understand
how the RF performance of user devices

including smart phones, lap tops and net books and network devices
including cellular base stations and TV broadcast transmitters
will determine future spectral value.
