# §90.351. Location and Monitoring Service.


These provisions authorize the licensing of systems in the Location and Monitoring Service (LMS). LMS systems utilize non-voice radio techniques to determine the location and status of mobile radio units. LMS licensees authorized to operate a system in the 902-928 MHz band may serve individuals, federal government agencies, and entities eligible for licensing in this part 90.

- (a) [Reserved]
- (b) LMS stations are exempted from the identification requirements of [§ 90.425](/cfr/47/90.425.md); however, the Commission may impose automatic station identification requirements when determined to be necessary for monitoring and enforcement purposes.
