Editing General Mobile Radio Service (section)

==Use of GMRS equipment in other countries==
The use of radio transmitters is regulated by national laws and international agreements. Often radio equipment accepted for use in one part of the world may not be operated in other parts due to conflicts with frequency assignments and technical standards. Some of the roles that the licensed GMRS service fills in the United States are, in other countries, filled by unlicensed or class-licensed services. Generally these services have strict technical standards for equipment to prevent interference with licensed transmitters and systems.

In [[Canada]], hand-held GMRS radios up to 2&nbsp;watts have been approved for use without a license since September&nbsp;2004.<ref>{{cite book |publisher=Industry Canada |id=RSS 210 |title=Low-Power Licence Exempt Radiocommunications Devices}}</ref><!--NB spelling of "licence" as per original --> Typically these are dual FRS and GMRS units, with fixed antennas, and operating at 2&nbsp;watts on some GMRS channels and 0.5&nbsp;watts on the FRS-only channels. Mobile units (permanently mounted in vehicles), [[base station]]s and [[Radio repeater|repeater]]s are not currently permitted on the GMRS channels in Canada.

Other countries have licensed and unlicensed personal radio services with somewhat similar characteristics, but technical details and operating conditions vary according to national rules. Many European countries use a similar 16&ndash;channel system near 446&nbsp;MHz known as [[PMR446]], as well as a 69&ndash;channel low-power [[LPD433]] which is shared with the 433.92&nbsp;MHz [[ISM band]]. GMRS equipment that is approved for use in the United States will not communicate with PMR446 radios due to using different frequency ranges.
