A Case Study in Broad System Analysis: DoD Spectrum Reallocation Feasibility Study, 1755-1850 MHz

Management Track



With the increasing demand placed on the electromagnetic spectrum by the proliferation of web enabled cell phones, the President has begun an initiative to sell 500 MHz of dedicated bandwidth from the federal government to the wireless industry.

The 1755-1850 MHz band was selected as the first band under this initiative for a study of the cost and technical feasibility of relocating DoD assets that use these frequencies. The study was incredibly broad as all services were involved, and the systems affected include Precision Guided Munitions, Point to Point Microwave, High Resolution Video, Multiple Radio Systems, Electronic Warfare, Air Combat Training, Telemetry, Satellite, and Small Unmanned Aerial Systems. OSD CAPE asked the Service Cost Agencies to develop cost estimates in a short period of time with little guidance and few ground rules.

A brief introduction to federal EM spectrum will be given, as well as an overview of the various types of systems affected. The cost estimating assumptions and ground rules the services agreed upon will be discussed. Then the different methods on gathering data and conducting analysis implemented by the services to address the problem will be compared with the pros and cons of each approach. The analogy method of estimating was used extensively, and its application to the affected systems will be conveyed. Finally, the results and lessons learned will be shared.
