Technical Factors Affecting the Assignment of Facilities in the Domestic Publc Land Mobile Radio Service

摘要

The Domestic Public Land Mobile Radio Service treated in this report is the two-way service with mobile units, employing separate frequencies for the base station and the mobile transmitters. Although the system parameters in both directions are important from an operational standpoint, only the reception of a base station by a mobile unit is considered, since this is the controlling factor for assignment purposes. The one-way signalling or paging service requires somewhat different parameters because of reduced receiving sensitivity and different modulation techniques and should be given separate consideration.
