  • DMR and Digital Voice Modes
    DMR and Digital Voice Modes Presented by N7MOT – Lenny Gemar Amateur radio began with spark gap transmitters, evolving to Morse code and analog voice communications, all originally in the Low Frequency (LF) and High Frequency (HF) bands. Since those early days, many new modes, both analog and digital have been developed. These modes now span from the Very Low Frequencies (VLF) to the Extra High Frequencies (EHF). This presentation is designed to acquaint amateur radio operators with the Digital Mobile Radio or DMR format of digital audio communications, used primarily in the VHF and UHF bands. We’ll briefly discuss the other four Common Air Interface formats (CAI) before diving into the specifics of DMR.

  • Licensed Mobile Radio Deployments Rose 4.5 Percent Globally in 2017
    Publication date: 15 Oct 2018 Author: Ryan Darrand Senior Analyst II, Critical Communications Licensed mobile radio deployments rose 4.5 percent globally in 2017 Brought to you by Informa Tech Licensed mobile radio deployments rose 4.5 1 percent globally in 2017 Highlights . Global deployments of licensed mobile radio (LMR) increased by 4.5 percent in 2017. Within the LMR market, the number of TETRA deployments increased by 16 percent globally in 2017. The number of deployments of cost-optimized digital technology also increased 16 percent in 2017, reaching more than $1 billion in revenue. IHS Markit expects it will be the fastest-growing LMR technology over the next five years. APCO P25 continued its success in the North American market, up by 4.3 percent, while TETRAPOL continued to refresh networks around the world. Our analysis Licensed mobile radio (LMR) deployments continue to increase globally, despite the emergence of LTE solutions onto the world stage and 5G on the horizon. Government and commercial sectors increasingly rely on LMR for secure, instant and reliable voice communications, so cost-optimized digital technologies, TETRA, P25, TETRAPOL and other major digital LMR technologies continue to attract investment. Overall digitization continues in the industry, as the number of digital users exceeded the number of analog users for the first time in 2017. However, there are a significant number of analog users who have not yet converted to digital-radio protocols. The global success of digital technologies has been multifaceted, as multi-tiered options, greater competition and advances in capabilities have provided an increasingly cost- effective migration path from analog to digital communications.

Digital Mobile Radio (DMR) was developed by the European Telecommunications Standards Institute (ETSI) and is used worldwide by professional mobile radio users. DMR is divided into three tiers. ◦ Tier I ◦ Tier II ◦ Tier III Tier I Tier I is a single channel specification originally for the European unlicensed dPMR446 service. It is a single channel FDMA 6.25 kHz bandwidth; the standard supports peer-to-peer (mode 1), repeater (mode 2) and linked repeater (mode 3) configurations. The use of the Tier I standard has been expanded into radios for use in other than the unlicensed dPMR446 service. Tier II (The Standard for Amateur Networks) Tier II is 2-slot TDMA 12.5 kHz peer-to- peer and repeater mode specification, resulting in a spectrum efficiency of 6.25 kHz per channel.

    Next Meeting: Apr 16, 2013 at 7:30 PM Mar/Apr 2013 Letter from the MARC President This will also be an opportunity to bring in your QSL cards so that we can submit them to the ARRL bureau. We did this at the September meeting and we plan to continue doing this twice a year. As part of your club dues, MARC will pay the postage and fees for the card submission. Remember to bring your ARRL membership number. · Our May meeting is ‘home brew’ night – that’s radio – not beer!! Tom Freeman (K3TF) will be showing us his home brew VFO and we’ll have time for other presentations as well – what have you made that you would like to share with the club? · Our next VE test session is May 4 – please contact Bob Lees (W3ZQN) if you would like to sign up to upgrade. Remember that one of the benefits of MARC membership is one free test session per year. · Field Day is June 22/23. This will also be our club picnic – a new feature. Steve Ikler (KS3K) - that’s Steve’s new Extra Call - will be our Field Day Captain, again and Yak (N3MQM) will be in charge of food. Thanks to Steve and Yak for making this happen but they are going to need lots of help Dear Fellow MARC Members: with set up, operating, making food and tak e down. Please let us know how you can help. I hope you are all enjoying 2013, which already seems to be slipping by – hard to believe it’s already the end of March.

  • An Overview of Digital Trunked Radio: Technologies and Standards
    บทความวิชาการ วารสารวิชาการเทคโนโลยีอุตสาหกรรม ปีที 10 ฉบับที 2 พฤษภาคม – สิงหาคม 2557 The Journal of Industrial Technology, Vol. 10, No. 2 May – August 2014 An Overview of Digital Trunked Radio: Technologies and Standards Kunagorn Kunavut* Abstract Land Mobile Radio (LMR) refers to the two-way radio communication system that allows users sharing the same range of frequency to communicate with the others. LMR can be roughly classified into two main systems which are conventional and trunked radio systems. In conventional system, a frequency band is permanently dedicated to a voice channel. However, using trunked radio system can increase the spectrum efficiency by having pool of frequencies which are temporarily assigned to a group of users called talk group only when required. In trunked radio system, analog trunked radio is going to be obsolete since digital trunked radio offers better functions and features in terms of voice quality, security, spectrum efficiency and cost. Hence, the commercial applications focus on the digital one. There are many digital trunked radio technologies lunched in the market. However, in this paper, only Terrestrial Trunked Radio (TETRA), Project 25 (P25) and Digital Mobile Radio (DMR) are discussed and compared since they are developed and standardized by international standards organizations. Moreover, these technologies are chosen by many users/operators and mostly deployed in many regions across the world.

    A Mikromakro Institute Report TETRA for Poland 8 July 2011 ORGANISATIONAL & BUS INESS MODELS ISBN 978-83-62824-01-4 TETRA for Poland Page 1 TETRA for Poland ORGANISATIONAL & BUSINESS MODELS The deployment and implementation of a single nationwide communications system for public protection and disaster relief services is a complex challenge for any country. Synergies in the technical organisation of communications systems must be created for a number of different services, governed by different regulations and financed from different sources, which requires adaptation to their specific needs. One cannot discard the experience gained from their earlier operations, but on the other hand, some old ways, like the physical ownership and control of infrastructure need to be changed, because it is now better to share infrastructure with others. Securing stable financing for a major project can be quite a challenge, as it will compete with other important public policy objectives financed from the national budget. Even when governed by uncompromising security or national defence requirements, public telecommunications projects are increasingly often planned as long-term cooperation with private partners. The telecom sector has been commercialised over the last decade or so, and learned the ways of the market economy. Even if not designed to compete with market players, state-operated projects must take account of the market environment or else they will be unable to cope with their operating costs or secure finance for development. When taking on new challenges in the area of telecommunications, the public sector may take advantage of the knowledge of the private sector in the fields of technology, infrastructure roll-out, management of telecommunications operators' costs or application of sophisticated financial instruments.
