HIPERLAN2 meaning

In legal and commercial documents, HIPERLAN2 describes a European wireless local area network standard for 5 GHz radio equipment, used in premises networking and comparable to early Wi‑Fi. Developed by ETSI’s BRAN group, it supports data rates up to about 54 Mbit/s and provides quality‑of‑service features for data, voice and video, with convergence layers intended to interwork with IP and 3G/UMTS systems. The term is not defined in legislation or case law; it is a descriptive technical label that may appear in procurement specifications, telecoms contracts, compliance schedules and spectrum policy materials. Legal relevance centres on regulatory compliance for 5 GHz RLAN equipment: licence‑exempt use subject to conditions (including power limits, indoor/outdoor restrictions, Dynamic Frequency Selection and Transmit Power Control) to protect other services. In the UK these conditions are set by Ofcom under the Radio Equipment Regulations; in Ireland by ComReg under the EU Radio Equipment Directive. Conformity is typically demonstrated against ETSI harmonised standards (for example those governing 5 GHz RLAN). Although largely superseded in practice by IEEE 802.11 variants, references to HIPERLAN2 persist in legacy agreements and due diligence. Usage and regulatory treatment are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland.
