TIA-TSB-88 and TIA-603 offer methodology support for assessing performance and interference in a P25 (Project 25) LMR (land mobile radio).

TIA-TSB-88

TIA-TSB-88 provides a standardized approach and methodology for the modeling and simulation of wireless communications system performance. This TSB (technical service bulletin) considers both analog and digital practices in all frequency bands of interest. The three volumes, or parts, of this TSB describe how to accommodate FCC (Federal Communications Commission) “spectrum refarming”, assess the impact of efficient band technologies on existing digital and analog technologies and vice versa, and address migration and spectrum management issues in the transition to efficient band technologies.

TIA-TSB-88 also provides information on new and emerging bands, as well as information on narrowband and wideband data. In addition, the TSB provides methodology to minimize interference between noise-limited systems.

ANSI/TIA-603

TIA-603 provides definition, methods of measurement, and performance standards for radio equipment used in the private (dispatch) LMR services that employ FM (frequency modulation) or PM (phase modulation) modulation, for transmission of voice or data using analog or digital techniques, with a frequency of 1 GHz (gigahertz) or less.
