The '''General Mobile Radio Service''' ('''GMRS''') is a [[Land_mobile_radio_system|land-mobile]] [[frequency modulation|FM]] [[Ultra high frequency|UHF]] [[radio]] service designed for short-range two-way voice communication and authorized under part 95 of the US [[Federal Communications Commission|FCC]] code. It requires a license in the United States, but some GMRS compatible equipment can be used license-free in Canada.  The US GMRS license is issued for a period of 10 years. The United States permits use by adult individuals who possess a valid GMRS license, as well as their immediate family members.<ref group=lower-alpha>The FCC definition of “immediate family” includes the licensee's spouse, children, stepchildren, parents, stepparents, siblings, grandparents, aunts, uncles, nephews, nieces, and in-laws. See {{CodeFedReg|47|95|1705|c}}.</ref> Immediate relatives of the GMRS system licensee are entitled to communicate among themselves for personal or business<ref>{{CodeFedReg|47|95|1731}}</ref> purposes, but employees of the licensee who are not family members are not covered by the license. Non-family members must be licensed separately.

GMRS radios are typically handheld portables ([[walkie-talkie]]s) much like [[Family Radio Service]] (FRS) radios, and they share a frequency band with FRS near 462 and 467&nbsp;MHz. [[Mobile radio station|Mobile]] and [[base station]]-style radios are available as well, but these are normally commercial UHF radios as often used in public service and commercial land mobile bands.  These are legal for use in this service as long as they are certified for GMRS under USC 47 Part 95. Older radios that are certified under USC 47 Part 90 are "grandfathered in", and can also be used legally for GMRS.{{Citation needed|date=November 2024}}

GMRS licensees are allowed to establish [[repeater]]s to extend their communications range.  However repeaters cannot be linked together over the internet nor connected to the [[public switched telephone network]].<ref name="linking">{{cite web | title=General Mobile Radio Service (GMRS) | website=Federal Communications Commission | date=2024-08-14 | url=https://www.fcc.gov/wireless/bureau-divisions/mobility-division/general-mobile-radio-service-gmrs#operations | access-date=2024-08-24}}</ref>

==Licensing==
Any individual in the United States who is at least 18 years of age and not a representative of a foreign government may apply for a GMRS license by completing the application form, online through the FCC's Universal Licensing System.  No exam is required. A GMRS license is issued for a 10&ndash;year term.<ref>{{cite web |publisher=FCC |title=GMRS Information |date=August 2011 |url=https://www.fcc.gov/general-mobile-radio-service-gmrs}}</ref>
The fee was reduced to $35 for all applicants on April 19, 2022.<ref>{{cite web |publisher=FCC |title=GMRS fee schedule |url=https://docs.fcc.gov/public/attachments/DOC-343611A1.pdf}}</ref>

A GMRS individual license extends to immediate family members and authorizes them to use the licensed system.<ref name="family">{{CodeFedReg|47|95|1705|c}}</ref> GMRS license holders are allowed to communicate with FRS users on those frequencies that are shared between the two services.<ref>{{CodeFedReg|47|95|1731}}</ref> GMRS individual licenses do not extend to employees.<ref name="family" />

New GMRS licenses are being issued only to individuals. Prior to July 31, 1987, the FCC issued GMRS licenses to non-individuals (corporations, partnerships, government entities, etc.). These licensees are [[Grandfather clause|grandfathered]] and may renew but not make major modifications to their existing licenses.<ref>{{cite web |url=http://wireless.fcc.gov/services/index.htm?job=licensing_1&id=general_mobile |publisher=FCC |series=Wireless Services: General Mobile Radio Service |title=Licensing: Eligibility}}</ref>

In any case, each GMRS station must be identified by transmission of its FCC-assigned call sign at the end of a transmission or a series of transmissions, and at least once every 15 minutes for a series lasting more than 15 minutes. The call sign may be spoken or sent with audible tones using Morse code. A repeater station handling properly identified transmissions of others is not required to send its own station identification.<ref>{{cite web |title=Electronic Code of Federal Regulations (eCFR) |url=https://www.ecfr.gov/cgi-bin/text-idx?SID=3adadbdfab9fb44c7685ffaa48d6fb89&mc=true&node=se47.5.95_11751&rgn=div8 |website=Electronic Code of Federal Regulations (eCFR) |language=en}}</ref>

==Range==
As with other UHF radio services, reliable range is considered to be [[Line-of-sight propagation|line-of-sight]] and the distance to the [[Line-of-sight propagation#Radio horizon|radio horizon]] can be estimated based on antenna height. Theoretically, the range between two hand-held units on flat ground would be about one or two miles (about 1.5–3 km). Mobile units might have a slightly farther range when mounted on a car roof. A GMRS repeater with an antenna mounted high above the surrounding terrain can extend the usable range to 20 miles or more (30+ km) depending on height. <ref>{{cite book |first=H. Ward |last=Silver |title=Two-way radios & scanners for dummies |publisher=For Dummies |year=2005 |isbn=0-7645-9582-2 |page=56}}</ref> Obstructions such as hills, trees, and buildings will reduce range. Higher power does not give much increase in range although it may improve the reliability of communication at the limits of line-of-sight distance.

== Frequency assignments ==
GMRS is allotted 30 frequency channels in the vicinity of 462&nbsp;MHz and 467&nbsp;MHz.  They are divided into 16 main channels and 14 interstitial channels.<ref>{{CodeFedReg|47|95|1763}}</ref>

Licensees may use the eight main 462&nbsp;MHz channels for [[simplex communication]] or [[repeater]] outputs.<ref>{{CodeFedReg|47|95|1763|a}}</ref>

The eight main 467&nbsp;MHz channels may only be used as repeater inputs,<ref>{{CodeFedReg|47|95|1763|c}}</ref> in conjunction with the 462&nbsp;MHz channels as outputs.  The repeater input frequencies are exclusive to GMRS, and may be used only by licensed GMRS operators.

GMRS operators are permitted to transmit at up to 50&nbsp;[[watt]]s [[transmitter power output]], on the 16 main channels,<ref>{{CodeFedReg|47|95|1767}}</ref> but transmitting 1 to 5&nbsp;watts is more common in practice.

The interstitial frequencies are in-between the main channels, and the 462&nbsp;MHz interstitial frequencies may be used for simplex as long as the [[effective radiated power]] (ERP) does not exceed 5&nbsp;watts.<ref>{{CodeFedReg|47|95|1767|b}}</ref>  The 467&nbsp;MHz interstitial frequencies have a power limit of 500&nbsp;milliwatts ERP,<ref>{{CodeFedReg|47|95|1767|c}}</ref> and only hand-held portable units may transmit on these channels.<ref>{{CodeFedReg|47|95|1763|d}}</ref>

=== Sharing with FRS ===
All 22 [[Family Radio Service]] (FRS) frequencies are shared with GMRS, and users of the two services may communicate with each other.  With the exception of FRS channels 8 through 14, GMRS licensees may use higher power radios with detachable or external antennas.


'''Suggested Channel Usage'''

Within the GMRS, any specific purpose of any channel is merely suggested (typically online by various groups), and is not required by the FCC regulations (different from some regulated channel assignments for [[Citizens band radio|CB radio]] or [[Marine VHF radio|Marine Radio]] for example). 

Channel 1, by its position as “default” on GMRS and FRS devices, tends to be the most often used, especially in urban areas. This suits it well as an SOS channel suggestion, due to more likely users on the channel. Beyond that, usage varies widely for all channels in both amount of traffic and purpose. Some websites list channel 20 as the “National GMRS calling channel”, or as the “Traveler’s assistance” channel, along with a suggested CTCSS tone of 141.3 Hz.<ref name=":02">{{Cite web |title=General Mobile Radio Service - The RadioReference Wiki |url=https://wiki.radioreference.com/index.php/General_Mobile_Radio_Service |access-date=2025-08-02 |website=wiki.radioreference.com |language=en}}</ref> It is unclear how well known (or followed) this or any usage suggestions are across the United States, but in general, channels tend to be selected by lack of radio traffic or by repeater pair availability, not an “official” or suggested purpose, using the required “listen before talk” regulation.

Exception: Licensees who operate North of Line A and East of Line C may not operate on channels 462.6500 MHz (channel 19), 467.6500 MHz (channel 19R), 462.7000 MHz (channel 21) and 467.7000 MHz (channel 21R), unless one's previous license authorized such operations.

[[File:GMRS and FRS Frequency Spectrum Chart.svg|thumb|GMRS and FRS radio frequency and power limitations]]

====Bandwidth vs channel spacing====
The FCC stipulates a specific channel bandwidth for FRS and GMRS. The bandwidth is constrained by the modulation which is FM deviation (GMRS = +/- 5.0 kHz, FRS = +/- 2.5 kHz) plus the uncertainties of the filtering of the transmitter and receiver. Additionally receivers and transmitters may drift over time or temperature so the bandwidth is further constrained to prevent interference to the adjacent channel. Channel spacing is 25 kHz for GMRS and so a 20 kHz bandwidth fits into that channel with protection on each side. FRS channels are spaced within a 12.5 kHz space directly between two GMRS channels. FRS radios generally utilize an 11 kHz transmitter bandwidth and a power lower than GMRS so the interference to an adjacent GMRS channel is minimized.

==History==
The predecessor to GMRS was named '''Class&nbsp;A Citizens Radio Service''' when it was commissioned in the 1940s. Tube-type transceivers were used, and transmitter power was limited to 60 watts (plate input power to the final amplifier tube). The original service ran wideband FM with ±15&nbsp;kHz transmitter deviation and 50&nbsp;kHz channel spacing. At the time, this was the norm for all U.S. land mobile services. There was also a Class&nbsp;B Citizens Radio Service which used a different set of 461&nbsp;MHz channels and was limited to five&nbsp;watts output. Business users were permitted to license in this radio service. Radios were built by consumer electronics firms and commercial two-way radio vendors.

In the 1960s, the UHF 450–470&nbsp;MHz band was re-allocated to 25&nbsp;kHz channels. This meant transmitter deviation was reduced to ±5&nbsp;kHz. This doubled the number of channels available across the entire 450–470&nbsp;MHz band. Class&nbsp;B Citizens Radio Service channels were re-allocated to other radio services.

In the 1970s, allowed power was again changed to 50&nbsp;watts across the output terminals of the transmitter. In 1987, licensing of business users was discontinued and businesses were allowed to continue operating until their licenses expired. There was congestion on all channels in larger [[metropolitan statistical area]]s and moving businesses to [[Business band|Business Radio Service]] channels would provide some relief. The radio service was changed to its present name; General Mobile Radio Service or GMRS.

In 2010 the [[U.S. Federal Communications Commission]] (FCC) proposed removing the individual licensing requirement. In 2015, the FCC ruled to keep the license requirement, but to remove the regulator fee for licensing.<ref>{{cite web |url=http://transition.fcc.gov/Daily_Releases/Daily_Business/2015/db0521/FCC-15-59A1.pdf |title=FCC-15-59A1 |series=Daily Releases }}</ref> Adopted on May 20, 2015, the ruling would be in effect after a 90&ndash;day notification period to Congress; the fee will not be eliminated before August 18, 2015.<ref>{{cite web |url=http://transition.fcc.gov/Daily_Releases/Daily_Business/2015/db0521/FCC-15-59A1.pdf |title=FCC-15-59A1 |page=9}}</ref> The fee for a 5&ndash;year license was $90, with the regulatory fee portion of the license at $5&nbsp;per year (or $25 for the 5&ndash;year life of the license). After the notification period, the fee for a 5&ndash;year license was to become $65. The change became effective on September 3, 2015. 

Effective September 28, 2017, FCC revised the definition of the FRS service. FRS operation is now permitted with up to 2&nbsp;watts on the shared FRS/GMRS channels. The FCC will not grant certification for hybrid radios that would exceed the limits for the FRS service on the FRS channels. Current "hybrid" FRS/GMRS radios will not require a GMRS license for power up to 2&nbsp;watts, but FRS radios will still not be permitted to use the input frequencies of GMRS repeaters. Any radio exceeding the limits of the new FRS service will be classified as a GMRS radio.<ref name=FCC-GMRS-FRS-Reform-2017>{{cite web |url=http://transition.fcc.gov/Daily_Releases/Daily_Business/2017/db0522/FCC-17-57A1.pdf |title=FCC Part 95 Personal Radio Services Rules Reform |publisher=Federal Communications Commission |access-date=May 19, 2017 |quote=Paragraphs&nbsp;51 and 52 list the changes on the FRS / GMRS channels and power restrictions. These modifications are meant to affect previous FRS / GMRS hybrid radios in the United States that were commonly sold to redefine them as FRS radios, since many users that purchase these radios did not know the FCC license requirements. As a result, these users will not require a GMRS license. Radios transmitting higher than the new FRS power restrictions are re-defined as GMRS radios and users will require a GMRS license to use these devices. The changes (channels and power limitations) went into effect on September 28, 2017. |df=mdy-all}}</ref>

On September 30, 2019, it became unlawful in the United States to import, manufacture, sell, or offer to sell radio equipment capable of operating under both GMRS and FRS.<ref name=PRS_reform_2018Aug29>{{cite web |url=https://www.federalregister.gov/documents/2017/08/29/2017-17395/personal-radio-service-reform |title=47 CFR § 95.1792 |series=Personal Radio Service reform |date=August 29, 2017}}</ref>

==Use of GMRS equipment in countries outside the US==
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.

==GMRS License fee change==
Currently, the application fee for a GMRS license is $35.  An FCC Report and Order released December 23, 2020, and in a subsequent notice issued by the FCC on March 23, 2022, the fee dropped from $70 to $35 starting on April 19, 2022. The license is still valid for 10 years and covers an entire family.

==Repeater Linking==
GMRS used to be regularly linked to other [[repeater]]s. The common practice for this linking was done via internet. This was commonly referred to [[GMRS Linking]] using [[Node_(networking)|Nodes]] running a modified [[HamVoip]] version of [[Asterisk_(PBX)|Asterisk]] .

Around January 24, 2024 the FCC changed the wording on GMRS operations page that said "You cannot directly interconnect a GMRS station with the telephone network." to now include (among other things) "or any other network".<ref>{{cite web | url=https://www.youtube.com/watch?v=86FLGl_e5nw | title=21 Group FCC ARRL Luncheon | website=[[YouTube]] | date=27 January 2024 }}</ref> As of November 1, 2024 it now has this added to the operations tab: "In other words, repeaters may not be linked via the internet—an example of an “other network” in the rules—to extend the range of the communications across a large geographic area.  Linking multiple repeaters to enable a repeater outside the communications range of the handheld or mobile device to retransmit messages violates sections 95.1733(a)(8) and 95.1749 of the Commission's rules, and potentially other rules in 47 C.F.R.  Repeaters may be connected to the telephone network or other networks only for purposes of remote control of a GMRS station, not for carrying communication signals. "<ref>{{cite web | url=https://www.fcc.gov/wireless/bureau-divisions/mobility-division/general-mobile-radio-service-gmrs | title=General Mobile Radio Service (GMRS) &#124; Federal Communications Commission }}</ref>  Wording changes did not affect local repeaters. This change did shut down several major nodes.<ref>{{cite web | url=https://ncgmrs.net/network-shutdown/ | title=Network Shutdown – North Carolina GMRS Network | date=20 August 2024 }}</ref><ref>{{cite web | url=https://www.texasgmrs.net/fcc-changes/ | title=Texas GMRS Network }}</ref><ref>{{cite web | url=https://forums.mygmrs.com/topic/8329-mygmrs-network-shutting-down-august-28th-2024/ | title=MyGMRS Network Shutting Down August 28th, 2024 | date=21 August 2024 }}</ref> This change was not an official act; it was instead done through interpretation set forth by the [[Chevron_U.S.A.,_Inc._v._Natural_Resources_Defense_Council,_Inc.|Chevron Deference]]. The changes and shutdowns of nodes has drawn mixed reactions.<ref>{{cite web | url=https://forums.radioreference.com/threads/gmrs-repeater-linking-and-the-fcc.475143/ | title=GMRS repeater linking and the FCC | date=21 June 2024 }}</ref><ref>{{cite web | url=https://forums.mygmrs.com/topic/8306-fcc-gmrs-service-operations-page-updated-04-aug-2024/ | title=FCC GMRS Service Operations Page Updated 04 Aug, 2024 | date=18 August 2024 }}</ref>
