Mission Critical Public-Safety Communications Testing

Mission Critical & Public Safety Equipment Testing

When catastrophic events, disasters and other emergency scenarios occur we rely upon the services of the fire and rescue authorities in collaboration with police and ambulance services – or Blue Light services.


In these situations the Blue Light services need to communicate with each other and, for that matter, with the victims by using Mission Critical voice and data communication.


Mission Critical Push to Talk (MCPTT) and Public Safety (PS) communication devices now incorporate the latest 3GPP LTE technologies to offer a broader spectrum of services to First Responders, based upon higher volume, backhaul bandwidth transmissions which may include image, video and HD voice transmitted over 4G LTE networks.

IoTAS are ideally suited to test these services against the Operator Networks supporting MCPTT and PS communications with our GCF certification status as an RTO, field experience testing LTE technologies and being a GCF ACE. This certification status is backed up by our continued UKAS ISO 17025 quality accreditation, ensuring the highest standards of testing, recording and report presentation.

Different Standards

There are three main transmission standards currently in play and guiding the Mission Critical arena

  • Project 25 (P25) is a suite of standards for digital mobile radio communications designed for use by public safety organisations in North America.
  • Terrestrial Trunked Radio (TETRA), is a European standard for a two-way trunked radio system and was specifically designed for use by government agencies, emergency services, the military, etc. and for public safety networks. It is the European version of trunked radio similar to Project 25.
  • Digital Mobile Radio (DMR) is an open digital mobile radio standard defined in the European Telecommunications Standards Institute (ETSI) Standard, used in commercial products around the world and increasingly in PS.

Accordingly there is no single governing test specification or suite of specifications that dictate how the 3GPP interoperability shall be tested although the likes of the TCCA, GSMA, ETSIGCF, FirstNet and the PTCRB  are working towards defined standards for cellular certification testing.


Our Pragmatic Test Solutions

Whilst the market awaits definitive 4G LTE Mission Critical testing specifications IoTAS are able to offer MC and PS communication device manufacturers, whose devices utilise 3GPP Radio Access Networks, pragmatic product testing to an agreed standard and level of certification, based upon the latest guidelines, test methodologies and, where appropriate, test equipment.
