MPT1327
Analogue Trunking Systems
MPT
1327 is a industry standard for trunked radio communications
networks. It was developed in 1988 by the British Department
of Trade and Industry (DTI), Although a British standard it is
widely used around the world and the most used trunked radio
protocol. MORE>>
TETRA
Digital Trunking
Tetra
is a standard specified by the European Telecommunications Standards
Institute (ETSI) during the '90s in response to the need of a common
digital trunked standard for PMR. ETSI standard assures the interoperability
between various manufacturers terminals that can indistinctly operate
on any TETRA network, the user requirements fulfillment and a future-proof
technology. MORE>>
DMR Digital
DMR
(Digital Mobile Radio) is a digital radio standard for Professional
Mobile Radio (PMR) users developed by ETSI under its ERM Technical
Committee. The standard is designed to operate within the existing
channel spacing used in land mobile frequency bands in Europe.
DMR is specifically targeted at small to medium sized PMR systems
where analogue PMR is currently applied today. The primary goal
of the DMR standardization is to specify a digital system with
low complexity and low cost levels. It will provide voice, data
and other supplementary services. MORE>>
APCO
P25
APCO-25
(Association of Public Safety Communication Officials – Project
25) is an open standard for digital radio developed in North America
under state, local and federal representatives and Telecommunications
Industry Association (TIA) governance. The standard was developed
to foster the development and progress of the art of public safety
communications. MORE>>
Conventional
Conventional
system is the most basic radio communications system. Conventional,
as its name implies, refers to a "traditional" method of frequency utilization. Conventional radios operate on fixed channels
and each user group is permanently assigned a fixed frequency or
a set of frequencies. MORE>>
