For a long time, FM broadcasting was a monopoly market in Germany. First operated by Deutsche Post and later by Deutsche Telekom and its subsidiary Media Broadcast, which has since been sold to Freenet. The broadcasting operations were paid for by the private and public broadcasters in Germany, which was a lucrative business for the operators.It has been clear for some time that the redesign is not going according to plan. In the middle of March a hastily arranged round table tried to find a way out. There, antenna investors, location owners, network operators, representatives of private radio, ARD and Deutschlandradio, representatives of the federal states, the Federal Network Agency and the Federal Cartel Office discussed and negotiated. A total of 40 of the most important players in the German radio market came together to prevent the signal blocker.Digital broadcasting in the form of DAB (Digital Audio Broadcasting) was seen as the successor to analogue VHF broadcasting. It was planned to end analogue broadcasting of broadcasting programs in the EU in 2012, once digital broadcasting had spread. This goal was clearly missed, see analog shutdown. In Germany and Austria, the conventional DAB standard could not establish itself, in Austria it was even discontinued. In the meantime, the incompatible successor DAB + was introduced, first in Germany, and later also in Austria. Although the introduction of DAB was more successful in Switzerland, it has now been replaced by DAB + there too. In the rest of Europe the situation is confusing, in some places operations have been stopped again, in other countries it seems to be partially successful.GPS tracking technologies are on the rise as new innovations continue to be developed. With the prevalence of smartphones and IoT devices, every location, online search, website visited and purchase made is being tracked. While many people are willing to share their location for good purposes, there is another set of people who want to hide their location.A <strong>GPS jammer</strong> is a device used to conceal one’s whereabouts by sending radio signals with the same frequency as the GPS device. Once this occurs, the GPS device is unable to determine its position due to interference.The GPS jamming unit itself is typically a small, self-contained, transmitter that generates a 1575.42 Mhz interference signal over a 5 to 10 meter radius.A jammer makes it difficult or impossible to receive a radio signal (e.g. from radio, television, mobile communications or GPS) properly. The jamming transmitter, just like the transmitter to be disrupted, sends out electromagnetic waves and completely or partially superimposes the original waves. It can work on the same or a neighboring frequency of the disturbed receiver. The field strength, the modulation of the jammer and the type of the disturbed message are important.
