Sometimes what you don’t know CAN HURT YOU? Ignorance around this subject matter is almost guaranteed to do so.
Project partners Kathrein and Rohde & Schwarz have reached two important milestones of the 5G TODAY research project: Kathrein completed an innovative antenna for test operation at BR’s transmitter site in Ismaning near Munich. In addition, a Rohde & Schwarz transmitter successfully went into operation at Bayerischer Rundfunk’s (BR) Wendelstein transmitter station. The specially developed Kathrein antenna and the high-power transmitter are part of the LTE Broadcast test transmission.The 5G TODAY project is funded by the Bavarian Research Foundation and led by the Institute for Broadcasting Technology, IRT. Further project partners are Bayerischer Rundfunk (BR) and Telefónica Germany.
The new 5G network standard is a key technology for the future when vehicles become highly automated and devices are networked with each other in the Internet of Things. 5G also offers great potential for efficient distribution of media content. The introduction of 5G will open up a worldwide market with millions of smartphones and tablets acting as potential TV receivers able to combine live TV services, media libraries, social networks and many other media services.
LTE Broadcast, also known as FeMBMS (Further evolved Multimedia Broadcast Multicast Service), was specified in 3GPP Release 14 in June 2017. It defines new options for broadcasting to LTE-enabled mobile user equipment such as smartphones and tablets. For the first time, the upgraded standard allows high-power high-tower (HPHT) applications in downlink only mode while utilising the full signal bandwidth for multicast/broadcast applications. Moreover, 3GPP Release 14 defines an extended cyclic prefix (guard interval) and modes to enable operation without SIM cards, which is necessary for broadcast applications.
The transmitters in Ismaning and on the Wendelstein form a Single Frequency Network (SFN), which is to enable mobile and portable reception in the greater Munich area as well as on the main traffic routes between Munich and Salzburg. Communication technology specialist Kathrein developed a special antenna for the transmission of diversity signals for the transmitter station in Ismaning. Twelve innovative UHF antenna fields were installed at a height of 200 meters. The project also included the installation of a 370-metre long, arm-thick HF transmission cable. Another Rohde & Schwarz high-power transmitter with 7 kW output power for 100 kW ERP is to be connected to the antenna at the end of January. The test broadcasting network will then be prepared for the measurements.

Presented by Dr Devra Davis, Visiting Professor of Medicine at the Hebrew University Hadassah Medical School, and Visiting Professor of Medicine at Ondokuz Mayis University, Turkey.
The Lecture
What are the health effects of mobile phones and wireless radiation? While Australia has led the world in safety standards, including compulsory seat-belt legislation, plain packaging on cigarettes, and product and food disclosure legislation, it falls behind in addressing the significant issues associated with mobile phone use. In this Dean’s Lecture, epidemiologist and electromagnetic radiation expert, Dr Devra Davis, will outline the evolution of the mobile phone and smartphone, and provide a background to the current 19 year old radiation safety standards (SAR), policy developments and international legislation. New global studies on the health consequences of mobile/wireless radiation will be presented, including children’s exposure and risks.

Let us try it out: Antenna transmission power is anywhere between 250mW (expressed as 24 dBm) for a Small Cell, and 120W for the largest 5G MIMO arrays (which is 50 dBm). A typical 2G, 3G, or 4G antenna has got a transmission power of 20W (43 dBm).
Let us quickly apply that to a user, standing in a relatively small distance to the transmitter:
A Small Cell is comparable to a WLAN access point, and you can come pretty close. We assume a distance of 10 m and get a path loss of 7.3+37.6=44.9dB. Subtraction of path loss from transmission power gives 24dBm – 45dB = -21dBm, which corresponds to approximately 8 µW. (µW is the 1 millionth part of a Watt)
A 5G macro cell antenna will be placed up on a tower or on the roof of a high building. Height above ground is thus some 30 m, and we assume a position in 100 m distance from the antenna. Path loss can be calculated to as =82.5dB. The received power is 50 dBm – 82.5 dB = -32 dBm, which is less than one µW.
A light bulb has about 60W energy consumption, and the emitted light and heat will be in that range. Since hat home your distance to a light bulb will be 2-3 meters. The impact from the light bulb on your body will be more than a million times higher. In is general consensus in medical and biological research that the only impact of microwave radiation, as the one used in mobile networks, is by heating up the target object.

The 5G Today project has officially started its field trial for TV broadcasting via 5G at a kick-off event at German broadcast technology research institute IRT in Munich today.
The project partners Bavarian public broadcaster BR, IRT, Kathrein, Rohde & Schwarz and Telefónica Deutschland are jointly testing broadcasting options for 5G technology. The new large-area 5G field trial in the Bavarian alpine region is covered by two high-performance transmitters at BR transmitter sites in Ismaning near Munich and on the top of the Wendelstein mountain. Both operate with 100 kilowatts ERP.
With the help of the high power of the transmitters and the high transmission towers (HPHT), the broadcasting of TV channels covering large areas can be tested based on the new broadcast mode FeMBMS (Further evolved Multimedia Broadcast Multicast Service). FeMBMS allows far-reaching distribution of content across large coverage areas with a radius of up to 60 kilometres.
The 5G Today project is intended to lay the foundation for the efficient transmission of broadcast content in 5G networks. It has been supported by the Bavarian Research Foundation since 2017.
“I am delighted that today we can launch the world’s first large-scale test network for 5G broadcasting,” said Ulrich Wilhelm, director general of BR and currently chairman of German public broadcaster association ARD. “We must design our future digital communications infrastructures in such a way that everyone can continue to benefit from the diversity of media content.”

US6506148What has been lacking so far in the distribution of broadcast content is an efficient and direct way of reaching users with live and linear content on mobile devices without additional costs for users. That is why BR together with IRT and three industry companies launched the 5G Today project in 2017. The project will test how 5G broadcasting can be used to create an overlay infrastructure that can simultaneously serve millions of future 5G mobile reception devices. The aim is neither to occupy the regular mobile networks nor to incur additional costs for citizens.
The two test transmitters are operated as a single frequency network (SFN) on channel 56/57 (750-760 MHz). Kathrein provides the antenna system while HPHT transmitters from Rohde & Schwarz are used for the 5G transmission. Telefónica Deutschland is contributing the frequencies.
“With this field trial covering Munich and the Bavarian alpine region, we now have a unique and true pioneer project – even if it will still take a few more years for commercial reception devices to become available and before public operation will be possible,” said IRT’s managing director Michael Hagemeyer. “The test will provide important insights for our research.”
IRT is coordinating the project and is developing a prototype FeMBMS receiver based on a software-defined radio (SDR) solution. In future, this technology could be integrated into smartphones, tablets and TV sets for the reception of live and linear content over 5G. The test receiver for the kick-off event is provided by the Institute for Communications Technology of Technische Universität Braunschweig.
The test operation of 5G Today will run until autumn 2019, after which the results and further exploitation of the findings will be evaluated. The project ends on October 31, 2019.
