The Land Mobile Spectrum Efficiency - A Plan for Federal Government Agencies to use More Spectrum-Efficient Technologies report was released in October 1993. The IRAC established the Ad Hoc 210 committee to provide a forum for Federal Government agency member-representatives to present their views on telecommunication policies dealing with mobile systems. This committee provided extensive assistance to NTIA in the development of this study and plan. They described requirements of government departments and agencies for mobile radio communication services, and provided both technical and policy comments on the material drafted by NTIA technical staff. Their descriptions of technical requirements and discussions of the policy issues, and the practicality of implementing some of the proposals, contributed greatly to the initial draft of the study and plan. IRAC approved a draft of this study and plan based on the work of Ad Hoc 201. The study was then reviewed by NTIA, Department of Commerce and Congressional Senior Staff members. Their comments led to clarifications and amplifications of the proposed plan and procedures included in this report.
