Background
Have you ever been in a place where you
can’t use your wireless telephone—like skiing at higher
altitudes, camping in a remote area, or even shopping at the
mall? There are other wireless services that allow you to
keep in touch—personal radio services.
A personal radio service is a
short-range, low power radio transmission using a device or
devices that operate much like walkie-talkies. Personal
radio services include one and two-way voice services, data
transmission, and transmissions that operate equipment by
remote control. The most popular types of personal radio
services are Citizens Band Radio Service (CB), Family Radio
Service (FRS), General Mobile Radio Service (GMRS), Low
Power Radio Service (LPRS), and Multi-Use Radio Service
(MURS). Of these types of personal radio services, only GMRS
requires an FCC license to operate.
Personal radio services offer several
benefits over other services. Devices generally are not very
expensive, usually can be hand-held, and work without the
need for transmission towers or other equipment. Some types
of personal radio services, generally those that are
authorized in the very high frequency (VHF) and ultra high
frequency (UHF) portions of the radio spectrum, do not
suffer from the static, noise, and fading that you may
encounter using CB service or walkie-talkies. In addition,
using a personal radio service requires no service contract
or monthly fee.
Here’s more information about
each of the most popular types of personal radio services:
|
Citizens Band Radio Service
(CB)
-
CB service allows private,
two-way radio communications for personal or
business use. Communications (or attempts to
communicate) with stations over 250 km (155.3
miles) away are prohibited. The maximum
authorized power levels vary depending on
whether the station is transmitting a single
side band (SSB) or an AM signal. SSB
transmissions are authorized up to 12 watts Peak
Envelope Power (PEP), while AM transmissions are
permitted up to four watts carrier power.
-
CB radios, used most
frequently in vehicles and by truckers, can be
purchased for between $70 and $200.
-
You must use an
FCC-certified CB unit in the United States.
FCC-certified CB units have an FCC-certified
label placed by the manufacturer.
-
There is no minimum age
requirement to operate a CB radio.
-
CB service operates on 40
shared channels on a “take-turns” basis, meaning
no CB channel is assigned to any specific
individual or organization. Users must never
talk with another station for more than 5
minutes continuously, and must wait at least one
minute before starting another communication.
-
You may not raise the power
output of your CB unit, attach any type of power
amplifier, or modify the unit internally.
-
CB Radios are generally not
suitable for anything other than 'truckers' use
as an informal radio mode, and the talk heard on
them is generally not for family ears!
|
Family Radio Service (FRS)
-
FRS allows two-way voice
communications over very very short distances, generally
less than one-half mile. It is generally used by
families or small groups to communicate while on group
outings when group members are fairly close together,
but can also be used in business-related settings.
-
An FRS unit looks and works much
like a walkie-talkie. Prices for FRS units vary
depending on features and quality.
-
If you have a dual-use, FRS-General
Mobile Radio Service (GMRS) unit, you may legally use
only the FRS channels unless you
have a GMRS license. The label on the unit or the
operations manual should indicate the service the unit
is certified for. FRS-only units transmit at lower power
levels and have antennas that are integrated with the
unit; GMRS units transmit at higher power levels and DO
NOT have detachable antennas.
-
You can operate your FRS unit
anywhere in the U.S. and its possessions. Before using
FRS in other countries such as Canada and Mexico, check
to see if that country allows operation of FRS units.
There is no minimum age requirement for operating an FRS
unit.
General Mobile Radio Service (GMRS)
-
GMRS is a land-mobile radio service
available for short-distance, two-way communications to
facilitate the activities of an adult (18 years or
older) and his or her immediate family members,
including a spouse, children, parents, grandparents,
aunts, uncles, nephews, nieces and in-laws.
-
GMRS Radios are NOT for Business Use,
and such use is subject to very heavy fines.
-
A GMRS system may legally be
operated only with a license
granted by the FCC. The individual licensee is
responsible for the proper operation of the GMRS system.
-
A GMRS system is made up of station
operators and a mobile station consisting of one or more
mobile units. It may also include one or more land
stations. Some land stations operate as repeaters,
thereby extending the range of GMRS mobile units.
-
New GMRS licenses are granted
only to individuals, but
GMRS licenses granted to non-individuals and businesses)
before July 31, 1987,
can be renewed if certain conditions are met. You can
apply for a GMRS license on-line at
wireless.fcc.gov/uls/, or by filing FCC Form 605,
available at
wireless.fcc.gov/index.htm?job=all_wireless_forms.
The FCC fee is $85.00. Licenses are granted for five
years.
Low Power Radio Service (LPRS)
-
LPRS is a private, one-way
short-distance communication service that allows
stations to transmit voice data or signals for auditory
assistance to people with disabilities, people who
require language translation, and certain individuals in
educational settings. LPRS also allows stations to
transmit voice, data, or tracking signals for health
care-related communications and certain law enforcement
activities. Two-way communications are prohibited. LPRS
can also be used for network control communications in
the Automated Marine Telecommunications System (AMTS).
-
LPRS transmitters can be operated
anywhere in the United States. There is no minimum age
requirement to operate an LPRS transmitter.
Multi-Use Radio Service (MURS)
-
MURS is a private, two-way
short-distance voice or data radio communications
service used for personal or business activities. The
service operates on five Very High Frequency
VHF
channels, originally set aside for business use, but
subsequently made available for personal use.
-
MURS users must cooperate in using
the five channels to reduce interference to other users.
No user has priority over any other user, but all users
must yield to emergency communications. A MURS station
may not operate as a repeater station, including
store-and-forward packet radio operation, or a signal
booster.
-
Maximum allowable transmitter
output power for a MURS unit is
two watts. Transmission range
between two hand-held units varies depending on the
unit’s antenna height, terrain, and weather.
-
These radios operate on only FIVE
frequencies or Channels, they are
151.820, 151.880, 151.940,
154.570, and 154.600 MHz
, and again they are limited to
TWO WATTS output power.
Unlicensed Radio Operation
Be aware that if you operate a
radio transmitter that requires a license, or use a radio
that is authorized for use only in a specific service, in
another service, you may be fined or imprisoned, and/or the
equipment may be confiscated, the fines are up to $10,000
and Six Months imprisonment for each day of violation, don't
make make the headlines!
Mail Order and Big Box Store Radios
Be aware that although you may
have legally purchased your radios from a Big Box store or
Online vendor, these radios must be compliant in one of the
services above, and must not be used for Business Purposes,
other than the Low Power MURS use.
Commercial Two Way Radios do cost more,
are more reliable, require a license, and provide for
coordinated operation with other licensees. There is nothing
wrong with the low cost radios for personal use, but
Professional Users must use Professional Radios!
