DMR — Digital Mobile Radio (Digital Mobile Radio) is an open standard for digital radio communication, developed and described by ETSI (European Telecommunications Standards Institute) in 2005.

TETRA — infrastructure equipment for the arrangement of IP-infrastructure of different levels of scale in the areas of public safety, oil and gas industry, transport, utilities and commerce.

MIMO MIMO (multiple input/output) is a technology for wireless communications - where multiple antennas are used at both the source (transmitter) and the destination (receiver). The antennas at each end of the communications circuit are combined to minimize errors, optimize data speed and improve the capacity of radio transmissions by enabling data to travel over many signal paths at the same time.

TSM™ waveform supports flexible bandwidths while optimizing information flow over the network. All nodes in a network collaboratively receive and retransmit multi-hop networking traffic, maintaining overhead and maximizing reliable throughput. The TSM waveform supports simultaneous voice, data, video, and position location information (PLI). TSM’s non-routing approach ensures robust networking performance and scalability, especially in harsh RF environments.

APCO 25 (TErrestrial Trunked RAdio) is an open digital trunking radio standard developed by the European Telecommunications Standards Institute (ETSI) to replace the obsolete MPT 1327 standard.

PoC or "PTT Over Cellular" is a technology that uses broadband mobile and Wi-Fi networks to connect instantly with the push of a push-to-talk button. The technology is best known for its ability to provide fast communications over long distances without the cost of deploying and maintaining infrastructure and radio equipment alongside LMR networks.

PMR 446 — Digital Mobile Radio (Digital Mobile Radio) is an open standard for digital radio communication, developed and described by ETSI (European Telecommunications Standards Institute) in 2005.

LTE - a set of infrastructure solutions and devices to provide broadband wireless communication in public security services and emergency response teams in crisis situations.
