What is Project 25 phase2?

(P25) Phase 2 refers to P25 requirements and standards for a digital Common Air Interface (CAI), Time Division Multiple Access (TDMA) based, which provides one voice channel per 6.25 kHz channel spectrum efficiency. At this time, Phase 2 is all about traffic channels on trunking systems.

What is Project 25 phase1?

P25 Phase 1: The phase 1 Project 25 radios can operate in 12.5 kHz analogue, digital, or a mixed mode format. The Phase 1 radios use a form of modulation known as Continuous 4 level FM, C4FM. Phase 1 P25 compliant systems are backward compatible and interoperable with legacy FM systems.

What are P25 frequencies?

Project 25 (P25)

What is the difference between P25 and Tetra?

TETRA allows simultaneous voice and data services so that both needs are covered by a single network; while P25, as it does not provide simultaneous voice and data service, normally requires an additional radio system to cope with data requirements.

Is P25 required?

As a DHS grantee, am I also required to comply with P25 standards? Yes, DHS/FEMA grantees are required to comply with P25 standards when purchasing LMR equipment. This requirement and other conditions specific to DHS/FEMA grantees are outlined in Appendix D of the SAFECOM Guidance.

Is DMR compatible with P25?

This format guarantees that, if the two-way radio is P25 standard, it will work with other P25 standard two-way radios even from different manufacturers. Radios from multiple vendors designed with the DMR standard are guaranteed to work with each other.

What is P25 trunking?

The P25 trunking is a separate channel that is designated as the control resource and is different from the traffic channel in that it functions as a resource allocation and digital communication message bearer and handler between the RFSS (RF Sub-System) and the SU (Subscriber Unit).

What is P25 CAP?

The P25 Compliance Assessment Program (P25 CAP) is a formal, independent process for ensuring communications equipment declared by the supplier actually is P25 compliant and tested against the standards with publicly published results.
