47 CFR Part 22 Public Mobile Services

Public Mobile Services are radio services in which licensees provide mobile and related fixed radio telecommunication services to the public. As a leader in radio frequency regulatory compliance testing, Keystone Compliance recognizes the requirements needed for wireless radio manufacturers. Meeting the ETSI, FCC, and other wireless testing specifications can be challenging. Not only do we understand the challenges, but we help guide companies through the process.

Keystone Compliance is constantly developing partnerships in GMA and RF exposure testing. Furthermore, our wireless test engineers work with clients to quickly develop appropriate and concise test plans. Lastly, Keystone tailors each test plan to individual customer needs minimizing unnecessary costs and over-testing.

Summary of Wireless Public Mobile Service Compliance Testing

CFR 47 part 22 regulatory wireless testing and certification establishes conditions in which radio stations are licensed and used in Public Mobile Services. Applications for authorizations, or consent to the transfer of control of licensees in the Public Mobile Services must:

  • Demonstrate criteria to hold an authorization in the Public Mobile Services;
  • State how a grant would serve the public interest, convenience, and necessity;
  • Contain all necessary information required by the FCC rules or application;
  • Propose operation of a facility in compliance with all  FCC rules for Public Mobile Services.

Individuals may operate certified consumer signal boosters on frequencies regulated under part 22 of 47 CFR. Failure to comply with FCC rules will void the ability to operate a signal booster.

The definitions below are commonly used in the regulatory 47 CFR conformance testing standard.

Antenna – A device that converts radio frequency (RF) electrical energy to radiated electromagnetic energy and vice versa.

Mobile Station – One or more transmitters that are capable of operation while in motion.

Ground station – In the Air-Ground Radiotelephone Service, a stationary transmitter that provides service to airborne mobile stations.

Temporary fixed station – One or more fixed transmitters that normally do not remain at any particular area for longer than 6 months.

Scope of Wireless Standard Test Method 47 CFR FCC Part 22

Two or more pending applications are considered mutually exclusive. This is true if the grant of one application effectively prevents the grant of one or more of the others. The Federal Communications Commission uses general procedures for processing mutually exclusive applications in the Public Mobile Services.

Applicants can construct facilities in the Public Mobile Services before their grant applications. However, applicants can not operate the facilities until the FCC allows it. Specified conditions are further mentioned in the 47 CFR standard.

Public Mobile Services carriers must attempt to coordinate the proposed use of spectrum with other spectrum users. This is carried out before applying authority to operate a station.

FCC permits are not required to operate, repair, or maintain equipment allowed in the Public Mobile Services. However, station licensees are responsible for the proper operation and maintenance of their stations.

During an emergency, licensees may use their stations to provide communication services in a manner or configuration not normally allowed by this standard specification. Examples include the disruption of communication facilities. Disruption can result from hurricanes, floods, earthquakes, other natural disasters, or national emergencies.
