LMR 100


The LMR 100 series provides a primer for anyone needing to design a land mobile radio system. The series, which is targeted to systems engineers, field engineers and radio technicians, covers the following topics:

  • Understanding LMR user needs;
  • The LMR user RFP process and technology assessment;
  • RF planning;
  • Connectivity and backhaul;
  • Dispatch, command and control;
  • Interoperability;
  • Radio site surveys, site selection, and field engineering;
  • Radio frequency interference;
  • Installation processes and standards;
  • Program and project management; and
  • Post-system project acceptance.

We welcome your feedback on these articles and also your suggestions on future topics.
