Also known as: CEPT, European Conference of Postal and Telecommunications Administrations
The European Conference of Postal and Telecommunications Administrations (CEPT) is the intergovernmental body through which European national regulators coordinate postal and telecommunications policy, most importantly the harmonised use of the radio spectrum.1 Founded in 1959, CEPT gives the regulators of nearly fifty countries a forum to agree common frequency plans and licensing approaches so that equipment and services work consistently across borders.2
Overview
CEPT works through several permanent committees. The Electronic Communications Committee (ECC) handles radio spectrum and does the technical heavy lifting: it issues ECC Decisions and Recommendations, publishes the European Common Allocation table, and manages harmonised band plans for services from broadcasting to short-range devices. A parallel committee deals with postal matters, and a third coordinates the European positions taken into global forums. CEPT decisions are not binding treaties in themselves, but members implement them nationally, which is why a licence-free band or a public-safety allocation tends to look the same from one European country to the next.
Historically CEPT also incubated technical standards work: the effort that became the GSM mobile standard began inside CEPT before being handed to a dedicated standards body. That spin-off created ETSI in 1988, and the two organisations remain closely linked — CEPT sets the regulatory and spectrum framework while ETSI writes the detailed technical standards that operate within it. CEPT also coordinates the common European brief carried into ITU meetings and the treaty-level conferences run by the ITU-R sector.
Relevance to SDR
For anyone scanning in Europe, CEPT is the reason the bands behave predictably. When you tune a European PMR446 walkie-talkie channel, a harmonised trunking allocation, or an ISM/short-range-device band, the plan you are listening across was almost certainly set by a CEPT/ECC decision that national regulators such as the UK’s Ofcom then adopted. That harmonisation is what lets a single band plan and a single receiver configuration make sense across the continent, rather than needing per-country retuning.
CEPT allocations shape where land-mobile trunking, amateur, maritime, and aviation signals live, and therefore where GopherTrunk users point their radios. GopherTrunk itself does not encode any regulatory data; it simply decodes whatever it receives. But understanding that a European deployment sits in a CEPT-harmonised band helps explain why the same frequency plans recur across countries and where to expect a given service.
