Permissible Operations

Multilateration LMS systems utilize non-voice radio techniques to determine the location and status of mobile radio units. Multilateration LMS systems are authorized to transmit status and instructional messages, either voice or non-voice, so long as they are related to the location or monitoring functions of the system.

License Period and Construction Requirements

Licenses are issued for a ten-year term from the initial license grant date. Licensees are required to construct and place in operation a sufficient number of base stations utilizing multilateration technology to provide multilateration location and monitoring service to one-third of the license areas population within five years of initial license grant and two-thirds of the population within ten years

Bidding Credits

A bidding credit acts as a discount on the winning bid amount that a bidder actually has to pay for the license. The size of the bidding credit depends on the annual gross revenues of the bidder, together with its affiliates and controlling interests, as averaged over the preceding three years
These bidding credits are not cumulative


LMS operates in the 902-928 MHz frequency band. The band is allocated for primary use by Federal Government radiolocation systems. Next in order of priority are Industrial, Scientific, and Medical devices. Federal Government fixed and mobile and LMS systems are secondary to both of these uses. The remaining uses of the 902-928 MHz band include licensed Amateur radio operations and unlicensed Part 15 equipment, both of which are secondary to all other uses of the band..
