In practice, common
base stations describes shared
private business radio (PBR) infrastructure. It covers: (a) a single‑channel base station made available to multiple independent users via a community repeater; and (b) a wider‑area PBR installation operated by one or more communications providers on commercial terms for several (usually business) users, enabling mobile radio communications.
The expression is descriptive rather than a defined statutory term, but is used in Ofcom and ComReg licensing contexts and in telecommunications and infrastructure agreements.
Operation requires an appropriate Business Radio spectrum licence and compliance with wireless telegraphy law (UK: Wireless Telegraphy Act 2006, administered by Ofcom; Ireland: Wireless Telegraphy Acts, administered by ComReg), including frequency coordination, interference
control and EMF conditions.
End users may hold their own PBR licences (for example, technically assigned) or access the installation under the operator’s licence, depending on the licence class and contract.
Projects typically involve site access and mast‑sharing arrangements (wayleaves/leases; UK Code rights under the Electronic Communications Code), planning consent for antennas, and health and safety duties.
Usage is broadly consistent across England and Wales, Scotland, Northern Ireland and Ireland, and commonly arises in spectrum applications, access and sharing agreements, and service contracts.
