Appendix B - FCC Information Spectrum and Regulatory Update Other Part 90 Frequency Options There are several other options that could be used depending on the availability of frequencies or existing infrastructure. • Section 90.235 - Secondary fixed signaling UHF or VHF high power bands. The fixed operations are secondary to mobile voice or data operations and must be licensed as part of the voice system. No additional channels can be added to accommodate the fixed operations. • 800 or 900 MHz private or commercial trunked systems - Fixed data can be added to existing trunked systems, although they do not count toward channel loading. • 700 MHz Guard band systems - Fixed data can be added to existing trunked systems although they do not count toward channel loading. • 700 MHz Public Safety systems - NPSTC (National Public Safety Telecommunications Council) is seeking a clarification from the FCC as to whether fixed data is permitted in the 700 MHz band in the same manner it is permitted in the 800 MHz band. • ASTRO 25 Digital Trunked Systems with Data option. Starting with release 6.3, MOSCAD data systems can be added to this digital trunked infrastructure. There are some differences in operation than with analog, so check with the MOSCAD product group for details. 177
