Stephen Temple

From engineer to policymaker

Stephen began his career in 1961 as a technician apprentice at Marconi. He worked in radar and satellite systems before joining the British Civil Service in 1971, initially working on radio spectrum for satellite communications.

It was an introduction to a problem that would recur throughout his career. New communications technologies needed access to frequencies that were often already being used by someone else. Finding room for innovation meant understanding the engineering, but also negotiating with existing users, other government departments and neighbouring countries.

By the mid-1980s, Stephen was working at the Department of Trade and Industry, where those skills would become central to the creation of a common European mobile system.

The agreement behind GSM

The ambition was straightforward: a mobile phone should work across national borders, using a common technology. Achieving it was anything but straightforward.

European countries had different networks, commercial interests and priorities. Even when engineers could agree on a technical solution, operators still had to commit to using it.

In 1987, Stephen drafted the GSM Memorandum of Understanding. Through that agreement, European mobile operators committed to a common digital standard and a timetable for introducing their networks.

The document did not invent GSM. Its importance was that it helped turn a technical ambition into a coordinated undertaking that operators and manufacturers could act upon.

Stephen also led the UK's contribution to establishing the European Telecommunications Standards Institute (ETSI) and became the first chairman of its Technical Assembly.

Another important contribution followed through the British Government's Phones on the Move initiative. Opening the 1800 MHz band to personal communications networks helped create space for greater competition and smaller, more affordable mobile telephones.

Beyond mobile phones

Stephen's work was never confined to cellular radio.

During his government career he was closely involved in the policies that helped Britain move towards digital terrestrial television and digital audio broadcasting.

After leaving the Civil Service, he joined ntl, where his work encompassed broadband Internet access, digital cable television and eventually the management of the company's networks division.

He subsequently worked in Vodafone's Group Corporate Strategy organisation.

These roles gave him experience of communications decisions from different sides of the table: first inside government, then inside the companies expected to invest in and deliver the services.

Returning to the spectrum question

The questions that had occupied Stephen during the early mobile years returned with 5G.

As a visiting professor at the University of Surrey's 5G Innovation Centre, he worked at the intersection of technical research, regulation, spectrum policy and government strategy.

He proposed a three-band approach to Europe's 5G spectrum needs, recognising that a national network required a combination of widespread coverage and additional capacity, rather than relying on a single frequency band.

The approach became part of Europe's 5G spectrum planning.

His subsequent work has continued to examine the relationship between new technology, spectrum, investment and public policy, including the questions surrounding the development of 6G.
