Open Q & A Session

 

The Project 25 Technology Interest Group is pleased to welcome

Leonardo Critical Communications (formerly Selex)

as a returning PTIG corporate member.

 

In 2017, the land mobile radio unit of Selex ES Inc. was rebranded as Leonardo Critical Communications.  They continue their legacy as a global manufacturer and provider of complete LMR solutions.  Leonardo provides LMR systems to critical agencies such as emergency services, law enforcement, utility, transportation, oil & gas, as well as professional enterprises.  

Leonardo radios have been in their DNA for over 60 years resulting in LMR solutions that are created with simplicity, reliability and flexibility even in the most challenging environments. Their systems are customizable to meet specific user requirements.

Leonardo’s primary LMR systems include: P25, TETRA, DMR

Leonardo has deployed their DMR, TETRA and P25 systems in over 50 countries around the globe, including the United States, Canada and Mexico.

Their Overland Park, Kansas facility is staffed with engineers and technical experts to support the Americas LMR business.  They have full system integration capabilities as well as stocking of finished goods, spare parts and renewal parts.  In addition, their customer support help line is staffed with LMR experts in Kansas.

Why Utilities Deploy P25

 

The P25 digital standard, originally designed for public safety, is making inroads with North American utilities.

Excerpt from the Mission Critical April May Utilities article:

“Many electric utilities are integrating P25-compliant technology into their radio systems. P25, a mature digital radio standard in use for 25 years, has not remained static. As the session initiation protocol (SIP) and real-time transport protocol (RTP) world of IP signaling evolved, P25 followed suit with the introduction of the Inter RF Subsystem Interface (ISSI), a network-tonetwork interface, and the Console Subsystem Interface (CSSI), a standard interface for connecting thirdparty consoles to the radio network. These interfaces offer customer choice and competition among multiple P25 suppliers.

After 25 years of evolution, P25’s array of supplementary services and features is extensive. P25 is flexible and versatile, allowing manufacturers to add features such as man-down emergency call, transmit-and-receive cycling and request-to-talk (RTT) callback, a feature commonly used in the utility industry.  While RTT is not defined within the P25 standard, both the CSSI and Common Air Interface (CAI) are flexible enough to introduce the signaling required to support it in both the consoles and radio terminals.”

David Deacon is founder and CEO of Etherstack. During the past 20 years, Etherstack has developed and licensed LMR technologies in Project 25 (P25), TETRA, Digital Mobile Radio (DMR) and NXDN to manufacturers around the world

Project 25 Technology Interest Group Publishes New P25 System Lists

 

New Updated P25 Systems Lists for March 2017 are now available on the Project25.org website.  There are updated lists for both P25 Trunking Systems and P25 Conventional Systems.  

Thanks to Ken Brown for his work as the primary author for these documents.

Since the lists were last published in June of 2016:

  • The P25 Trunking Systems list has 84 new systems added.
  • The P25 Conventional List has 35 new systems added.

 Both lists are organized by State or territory.  Systems are included for  the USA, UK, Australia, Canada, and New Zealand.  The data for each system includes Location, System Name, System type, P25 Phase 1 or P25 Phase 2, and the frequency band or bands used in the system.

 

The files can be accessed on the   project25.org   Website Homepage by clicking the Blue quick link boxes for:

  • List of P25 Trunking Systems
  • List of P25 Conventional Systems
