About the event

Many IoT end devices need to be compact and run from a battery. In these cases, the battery life needs to be many years to avoid regular replacement becoming a major part of the cost of operation. How do you design a system so it can run for years or even decades from a restricted power source?

This afternoon event will inform how you approach this considerable challenge. In this meeting, experienced practitioners of this type of system design will talk about suitable approaches, and perhaps reveal some of their battle-scars in gaining this experience!

Delegates will explore:

  • How often you can afford to send data
  • How often you can listen in order to receive configuration data or new software
  • How to implement an appropriate level of security without relying on communication with trust centres or intensive cryptographic processing

Starting at 14:00pm, the event will provide delegates with ample opportunities to network with fellow delegates and speakers to explore the themes of the event.

Employees of CW member organisations can attend this event for free. You will need to be logged into your CW account to access your free ticket – log in (or reset your password here)

Tickets for non-members are £150 plus VAT. CW membership may be more cost effective for your organisation than fully priced tickets – find out more about CW membership benefits.

Introduction to the CW from Simon Mead, CEO, Cambridge Wireless.


Welcome from our host, John Dow from PwC


Introduction to the event by Connected Devices SIG Champion, Tim Whittaker of Cambridge Consultants


Paul Williamson, ARM

‘Designing for one trillion devices’

Paul will take a look at low power design on the macro scale. What are the economics that will drive the system choices for scale. He will discuss some of the innovations in low power compute to support Energy harvesting, and how this fits as part of the technology stack for large scale secure deployment for IoT.


Paul Egan, 8Power

'The IoT Power Paradox'

There is no Moore’s Law for batteries. Showing how next generation energy harvesting can solve the Power Paradox problem for low power IoT wireless systems.


Sam Turner, Cambridge Consultants

‘The Language Barrier in IoT’

For companies outside the traditional consumer electronics industries, IoT is not just their first exposure to wireless connectivity, it may be their first exposure to electronics and software development of any kind. Bridging that gap in technical understanding is one of the first hurdles of an effective IoT development.


Refreshments and networking


Rob Meades, u-blox

'Viability Of Energy Harvesting For Cellular IoT'

NBIoT/Cat-M1 cellular is presented as providing a 10 year battery life, so could a real cellular IoT device powered from harvested energy offer infinite life, “fit and forget”? We tried building one to find out


Steve Braithwaite, CTO, ASH Wireless Electronics Ltd

'Designing for small, variable, intermittent power sources’

Sometimes it's not possible to use a battery, even a rechargeable one or an ultracapacitor. Ways of thinking about efficient use of energy, designing for it and validating the results are illustrated with examples of battery-less energy scavenging designs, together with a brief introduction to transient computing for OS's running on scavenged power.


Open Forum with all speakers chaired by SIG Champion, Nick Hunn, WiFore


Concluding remarks and event closes


Steve Braithwaite - Consultant, ASH Wireless Electronics

Steve founded ASH Wireless 19 years ago providing consulting design and product engineering support for wireless devices, sensors and electronics. Prior to that he worked in satellite communications and then taught communications engineering and electronics at the University of Southampton, with which he still works. Steve is also a business mentor at the Future Worlds accelerator in Southampton. 

Paul Egan - CEO, 8power

Paul has enjoyed a long career in wireless technology and IoT. In the early 90’s he was part of the initial team at ARM. In the late 90’s he joined CSR shortly after its creation playing a key role in design of its Bluetooth ICs, before co-founding LPWAN pioneer Neul in 2010. At Neul, Paul served as VP, Business Development. Neul was acquired by Huawei in 2014 and the Neul technology is being rolled out globally as NB-IoT. Before joining 8power, Paul worked as principal consultant at the Digital Catapult starting the IoTUK project. 

Rob Meades - Embedded Software Engineer, u-blox UK

Rob Meades is an embedded software engineer in the cellular technology group of u-blox, based in Cambridge, UK. He has worked on cellular communications devices, at all levels, since the last century

Sam Turner - System Engineering Group Lead, Cambridge Consultants

Sam has been developing wireless systems for over twenty years from cellular and satellite networks through to personal area networks and IoT. For the last ten years Sam has worked at Cambridge Consultants concentrating on connectivity for devices ranging from high-end audio to extreme low-power medical applications.

Paul Williamson - VP and GM, Emerging Businesses’, Arm

Paul’s team are building Arm business that delivers value from security for all the Lines of business. The team are focused on establishing revenue for integrated SIM and other services as well as managing the Arm security IP roadmap. Paul previously ran IoT and wireless business at Arm has been involved in connected devices since the early days of Bluetooth, developing innovative products for consumer, medical and industrial markets. Prior to joining Arm Paul led the low power wireless division of CSR, a fabless semiconductor business (now part of Qualcomm). Paul started his career in engineering consultancy, working with leading global brands to develop innovative products and services.  

SIG Champions

Paul Green - Creative Director, Iotics

Paul originated Arkessa in 2006 - the business that provides remote internet services to multitudes of machines. He is currently creating the services Arkessa will offer in five year's time. His professional life combined engineering and science has taken him through a variety of roles, including design and production engineering, business planning, marketing and corporate sales, mainly in the telecommunications sector. Interestingly, the first product he introduced to manufacture is now is in the Science Museum in London. A passionate and committed Christian, Paul is as excited about materials science and quantum physics as he is interested in railways, walking, skiing and the natural world.

Nick Hunn - CTO, WiFore Consulting

For the past thirty years Nick has been closely involved with short range wireless and communications, designing technology that helps to bring mobility to products, particularly in the areas of telematics, M2M, IoT, wearables, smart energy and mobile health. He is closely involved with the Bluetooth SIG, the Continua Alliance and other medical and wireless standards bodies. He is the author of 'The Essentials of Short Range Wireless' - a book attempting to explain the application of wireless technology to product developers.
