Public Safety Communications and Land Mobile Radio Standards, Markets and Technologies
PracTel Inc, Jan 2011, Pages: 275
This report analyses the progress in the digital Land Mobile Radio (LMR) development. The aim was to address up-to-date status of technologies, standards and markets for such radios with the emphasis on Public Safety Communications (PSC) applications.
The report is written for a large audience of technical, managerial and sales staff of organizations involved in the design, manufacturing and utilization Land Mobile Radio.
Particular, this report includes:
1. The updated analysis on the phased development of P25 radio. The current status of the technology, markets and standards and survey of vendors are presented. Though the standardization process started almost twenty years ago, commercialization is still slow; and the market development is unsatisfactory. This situation is addressed by all parties involved in the PSC development in the U.S.
2. The updated analysis on the phased development of TETRA radio. This technology found more geographically spread market segments than P25. Its Release II offers a combination of voice and data transmission that brings sufficient benefits to the users; but the growth of markets is still slow.
3. The analysis of the MESA project. This international effort (ETSI/TIA) started in 2000 with expectation to produce a “System-of-Systems” - advanced network architecture for PSC with the emphasis on data transmission (2 Mb/s and up). Currently this project, which generated a significant amount of documentation, is closed.
4. The analysis of major innovations in P25 and TETRA radio, including a) Software Defined Radio – SDR. SDR platforms bring many benefits for PSC, including multi-band transmission and interoperability, b) Utilization of the 700 MHz band.
5. The updated analysis on narrow-band LMR radios, including NXDN and MOTOTRBO. The NXDN radio development is a result of joint efforts of two companies, Icom and Kenwood and it is based on the FDMA technology. The companies developed two lines of products, IDAS (Icom) and NEXEDGE (Kenwood); these radios were implemented with many advanced technological features, including 6.25 kHz channels. At the same time, Motorola introduced its MOTOTRBO line of digital LMRs, which also utilized newer technologies and is based on the TDMA technology.
6. The analysis of the 4.9 GHz radio technology for PSC. The FCC allocated the 4940-4990 MHz spectrum for PSC broadband communications. The technology can utilize the existing Wi-Fi ICs, and it supports long-reach communications with speeds 50 Mb/s and up. It utilizes a) OFDM, b) Multi-radio platforms, and c) self-healing and self-organized mesh topology. The major 4.9 GHz radio applications for PSC are temporary fast-deployable networks.
The report addresses technical and marketing characteristics of discussed LMRs.
Target Audience:
This report is important for organizations using LMR. They need to understand the market dynamics and to be familiar with vendors’ portfolios to make a right choice in selection of equipment.
For LMR vendors, this report provides valuable information on competition. It also supports these vendors with the market assessments
Research Methodology:
Considerable research was done using the Internet. Information from various Web sites was studied and analyzed; evaluation of publicly available marketing and technical publications was conducted. Telephone conversations and interviews were held with industry analysts, technical experts and executives. In addition to these interviews and primary research, secondary sources were used to develop a more complete mosaic of the market landscape, including industry and trade publications, conferences and seminars.
The overriding objective throughout the work has been to provide valid and relevant information. This has led to a continual review and update of the information content.
