About Technigel Consulting

Nigel Garnham is a highly experienced principal technology consultant with over 30 years’ background in telecommunications and network engineering within IT and Operational Technology (OT) product development, integration and deployment programmes.  

In proposition development, he has led product and business technology teams to produce solutions delivered as part of major engagements – including the development of broadband network services, digital broadcast networks, multimedia contact centre and PSTN (landline) replacement for the energy and utilities industries.  He has worked as Technical Design Authority with clients as diverse as the BBC, BT Group, UK Water Companies, Civil Nuclear Industry, Devolved National Governments, NHS Digital and National Savings and Investments.

As an independent consultant, Nigel now offers these services to clients through Technigel Consulting Limited, undertaking the role of independent trusted adviser for critical infrastructure programmes focussed on the convergence of IT and OT.

Nigel has worked closely with client teams understanding the processes and challenges of their organisation, with detailed attention to requirements capture on both existing architectures and required business outcomes.  His strategy proposals, which have resulted in major infrastructure transformation programmes, have addressed the needs for efficiency, business change, low carbon and end-customer satisfaction.  Highly approachable, Nigel has a reputation for attention to detail and pragmatism.

Within the context of Information Technology (IT), Nigel’s specialist areas have included

• data centre migration to cloud digital applications (PaaS and SaaS)
• deployment of Software Defined Wide Area Networks (SDWAN), delivered over fixed internet, cellular and satellite networks and replacing costly legacy MPLS private networks
• adapting local area networks away from desk-based wired connectivity to AI-based wireless networks using the latest cloud-managed mesh technology
• replacement of PABX and traditional meeting room video and audio technologies with cloud-based collaboration services, providing a consistent experience agnostic of location and network delivery method

His strategy role in Atos resulted in him driving the Operational Technology (OT) network vision through their global experts’ community, including

• solutions and standards for edge networks, with strong focus on the development of IoT and associated low power radio solutions including LoRaWAN and NBIoT
• next generation 5G/6G LTE communications
• secure networks for industrial scale critical infrastructure applications, including the adoption of remote control for SCADA and increasing the granularity and frequency of remote measurement in applications such as transmissions networks, transport, electric vehicle charging and waste water monitoring

As a result, he is now equally as focussed on IT networks as he is for OT solutions and works closely on emerging IT/OT convergence strategy for energy and utilities infrastructure providers.  Nigel has provided consulting services covering regulated cybersecurity aspects in these sectors and is familiar with UK NCSC Security of Networks & Information Systems (NIS) Regulations and IEC 62443 frameworks.

In his consulting work, Nigel has led major bids and procurement activities under OJEU and orthodox programmes from PQQ right through to vendor selection and due diligence.

Nigel is a Chartered Engineer, a Fellow of the Institution of Engineering and Technology and member of the IET's Academic Accreditation Panel.  He is Associate Editor, IoT and Cognitive Networks, for the IET Smart Cities journal.
