Digital Radio, Indoor Coverage: Hot Topics at Largest PMRExpo
December 14, 2010
Cassidian's smart vehicle concept
By Max Zerbst
This year’s PMRExpo 23 – 25 November in Cologne, Germany, again experienced growth compared with last year’s figures. The 10th PMRExpo had 177 exhibitors from 14 countries, 2,730 visitors of the exhibition and more than 900 attendees of the three-day conference program.
As a new event, the exhibition hosted this year the Application Forum, a special show room for presenting solutions and applications. The organizer is confident that the forum will meet the increasing information needs of user groups of digital professional mobile radio (PMR) products and systems.
Strong emphasis in the conference program and among the exhibition was again TETRA, and in particular, the progressing national rollout of the German TETRA public-safety network. Topics such as interfacing to control centers, the requirements of end-to-end encryption, interfacing and scaling control centers and even some legal aspects found their way into the conference program.
Another topic of increasing importance is indoor radio coverage for public-safety networks in tunnels, railway and subway stations, and airports and other special locations. First responders are nervous about switching from analog to TETRA when there is not sufficient indoor coverage. This trend has accelerated during the past year with many discussions among all parties involved and was reflected as well in the conference program.
The market development of digital narrowband technologies such as Digital Mobile Radio (DMR), digital Private Mobile Radio (dPMR) and NXDN also were presented at the exhibition. The number of vendors is increasing, there is greater variety within product portfolios and an obvious market success.
Another technology in the exhibition was the Smart Vehicle Solution from Cassidian. This future concept for PMR equipment in a mobile environment demonstrated how various devices and applications used in a police car could be combined into one interworking solution. Cassidian built a demonstration model on a dashboard, complemented by a video presentation, to show how diverse elements in the vehicle environment, such as blue lights, speed control and cameras can be integrated with onboard communications equipment.
Since its establishment in 1990, the PMRExpo has shown continuous growth and is among the important marketplaces for PMR in Europe. Next year’s show will be in Cologne 22 – 24 November.
