LocusUSA, Releases its Latest White Paper on the Importance of Annual Maintenance for P25 Radio Systems


The Importance of LMR Sustainment and Continued Support for P25 Public Safety Radio systems cannot be understated. With over 2300 Project 25 Systems on the air, it is clear, that the majority of the public safety community agrees that P25 is the best choice for Public Safety Grade emergency communications interoperability. P25 is the recommended technology of choice for MCPTT Voice interoperability in the SAFECOM Grant Guidance and the DHS NECP.

The Project 25 Technology Interest Group (PTIG) is pleased to share information on innovative solutions for the testing and maintenance of Project 25 technology, subscriber equipment, and systems from our member companies.


LocusUSA, a leader in radio frequency capture for radio analysis and location, has announced the release of its latest white paper entitled, Assessing the Effects of Radio Failure in High-Risk Incidents: A Guide for Public Safety Agencies.

Visit LocusUSA’s website to download the white paper:

"We have taken an innovative approach to illustrate in this white paper the importance of why an agency needs to provide maintenance annually for their radio fleet," said Joseph Rey, manager partner of LocusUSA. "No matter the situation, clear and reliable communication will always be a non-negotiable necessity."

LocusUSA offers innovative solutions for long-range, over-the-air radio monitoring in P25 Radio Systems. Their over-the-air waveform analyzer acts as an ever-present monitoring tool that continuously assesses the health and operability of all subscribers on a system. The solution works by capturing and measuring a radios waveform in real-time while units stay deployed in the field. System users simply key up their radios for measurement, and from there, the solution analyzes the equipment to ensure optimal frequency performance 24/ hours a day, 7 days a week, without user intervention.

The analyzer also generates and sends reports to system managers so they can prioritize maintenance schedules based on subscriber performance.

P25 Sharing = Cost Savings for Stonington CT.

Stonington CT. Police are the Latest P25 Sharing=Cost Savings Success story. Full details were recently published in an article in “The Day” newspaper by Lindsay Boyle.

A link to this article is below.


In their agreement with the State Department of Emergency Services and Public Protection, Stonington spent $1.3 million to build a communications tower and purchase P25 radios. It is estimated that their Cost savings over having to build a stand-alone system was $3.1 million.

In addition to the cost savings, several improvements to the agency’s communications were realized. They now have coverage in a historic local dead spot with their new tower and they have interoperability with the Connecticut State Police and other municipal P25 systems for mutual aid using towers across the State. The interoperability for any state agency, as well as their neighbors improved tremendously.  Example: they – for the first time ever – shared a talkgroup and were able to communicate directly with their neighboring community.


Groton CT recently joined the Connecticut statewide system and Norwich is planning to join soon giving improved communications through P25 interoperability in the region. Many other municipalities — including ones in Rhode Island and New York are considering signing on.   The State of Connecticut is working on interoperability with communities in RI and a P25 System to System ISSI connection with the Metropolitan Transit Authority in NY (MTA has subscriber units already using the system)

PTIG Publishes Updated P25 Trunking Systems List May 2019

The Project 25 Technology Interest Group (PTIG) has published an updated P25 Trunking Systems List. There are currently 1017 P25 Trunking Systems identified for inclusion on the list. The list covers known systems in the US, Canada, Australia, New Zealand, and the UK. The list is organized by State and Nation. Thanks to Ken Brown for his research efforts to update this list.  Please send any additions/corrections to Steve Nichols This email address is being protected from spambots.

The full list can be downloaded using the link below:

P25 Trunking Systems List May 2019


There were 194 New P25 Trunking Systems Identified since the list was last published in 2017. Other major trends include a strong migration from P25 Phase 1 to P25 Phase 2 Systems. P25 Phase 1 Systems are down from 728 systems to 652 Systems while Phase 2 systems are up from 188 to 364 known systems. In addition, 93 P25 Systems have been merged or consolidated into larger Regional or State-wide P25 systems and are no longer listed as stand-alone systems. The net total with consolidations removed is up 101 systems from the 2017 list.

P25 Conventional Systems are found on a separate list on the PTIG website. There are 1334 Conventional Systems on that list. The grand total of P25 Systems both Conventional and Trunking is 2351.

P25 trunking List Changes 2017 2019

The P25 Trunking System List Includes System Name, P25 Phase 1 or P25 Phase 2, Primary User designation, Statewide System Designation, and the Frequency Band in use.

Public Safety remains the primary user type with DoD and Federal Agencies being the other primary user Groups. Additional P25 systems were recognized for Public Works, Utilities, Corrections (non Federal), Business, Airport/Transportation, and Universities. There are 37 Statewide P25 Trunking Systems recognized.

P25 Trunking User Type Chart

Frequency Bands in use remain dominated by 800 MHz, 700 MHz and UHF LO (380-420 MHz).
