Handheld two-way radios and low-power radio devices are regulated radio services in the overwhelming majority of countries and regions. Regulatory goals typically include preventing harmful interference, protecting public safety and emergency communications, allocating scarce spectrum rationally, and ensuring that equipment reaches acceptable levels of electromagnetic compatibility and electrical safety. So-called "license-free" or "personal" services are not rule-free. Rather, they impose strict conditions on power, bandwidth, antennas, intended use, or device class so that the public can use short-range equipment under predictable risk. Starting from this institutional background, the present article introduces the entry points and discussion contexts of several common jurisdictions. Specific frequencies, ERP, channel spacing, and equipment categories must be checked against the current rules, frequency-allocation tables, and type-approval catalogs of the competent authorities.

In the United States, the Federal Communications Commission (FCC) regulates personal radio services mainly under Title 47 of the Code of Federal Regulations, Part 95 (47 CFR Part 95). Within that framework, the Family Radio Service (FRS) and the General Mobile Radio Service (GMRS) differ in licensing requirements, power limits, and antenna restrictions, so readers should consult the relevant subparts and the latest amendments. Official texts are available through the FCC and the eCFR. In Europe, the European Conference of Postal and Telecommunications Administrations (CEPT) and the Electronic Communications Committee (ECC) publish harmonization recommendations, while ETSI develops EN standards used in conformity assessment. Individual countries nevertheless retain their own legislation and enforcement, so selling or using equipment in a particular country requires checking that country's telecom regulator. In the short-range device context, bands such as PMR446 are used under broadly similar conditions across many countries, but details concerning digital and analog modes, markings, and test requirements can still differ by jurisdiction.

Within the People's Republic of China, radio management is led by MIIT, while local radio authorities carry out day-to-day supervision and administrative enforcement. The Radio Regulations of the People's Republic of China form the upper-level institutional framework. Public two-way radio, professional radio, and amateur radio belong to different service categories, and frequencies and power levels must comply with supporting catalogs and documents. Authoritative information should be taken from the MIIT website and the currently valid texts published by local radio authorities. Anyone who sets up or uses radio stations without the corresponding permission or outside license-exempt conditions bears legal responsibility in accordance with law.

In Japan, radio affairs are administered by the Ministry of Internal Affairs and Communications (MIC). Its institutional wording does not map one to one to the market language of FCC Part 95 in the United States or "public two-way radio" in China. Categories such as household-use specified low-power radio, along with related technical requirements, are organized within the Radio Law system and the technical-conformity regime, and the relevant bands are generally not interchangeable with European or North American devices. Readers can start from MIC radio information and the Radio Use Portal for explanations in Japanese or English.

Agencies such as Innovation, Science and Economic Development Canada (ISED), the Australian Communications and Media Authority (ACMA), and New Zealand's Radio Spectrum Management (RSM) publish their own national conformity requirements and band allocations. Personal or license-free devices may resemble FCC-regulated products in some respects, but testing standards, labels, and restricted-use clauses must still be confirmed under local law.

Cross-border travel and cross-border e-commerce add another layer of complexity. Antenna gain, band plans, and permitted modulation vary by country. Equipment lawfully certified in one country may be non-compliant or unsafe in another. Network radio and application-layer PTT further involve telecom services, data protection, and content regulation, which belong to a different dimension from RF spectrum management and should be assessed separately.

Institutional rules are revised as spectrum is refarmed and technologies evolve, so readers should always check publication dates and amendment numbers. When reading this article alongside others in this volume, it is useful to begin with the historical timeline and then open the topical entries below as needed.
