IRL Dresden and R&S cooperate to research wireless technologies for industry 4.0
I
n order to realise industry 4.0 use cases such as mobile robots or automated guided vehicles, industrial network deployments must guarantee very high availability, reliability, and in many cases low latency communications. 5G NR technology including its latest enhancements specified in 3GPP Release 16 enables ultra-reliable low latency communications (URLLC), ideal for private campus network deployments. However, as with any wireless system, the communication link is subject to potential interference on the deployed spectrum bands.
The Industrial Radio Lab (IRL) Dresden is dedicated to researching and testing radio systems for industrial applications. In this effort, they cooperate with Rohde & Schwarz, a provider of 5G NR test solutions, which includes portable and easy to use test equipment for assessing a network’s performance in the field. Rohde & Schwarz has provided its high-performance network scanners to the IRL Dresden for distributed real-time radio spectrum and interference
monitoring. With this application, the researchers gather important data on how to detect, locate and prevent interference and to keep a local spectrum band clear for reliable wireless connectivity.
IRL Dresden is one of the four regional labs of the Industrial Radio Lab Germany (IRLG) that engages in research and development of current and future wireless technologies in industry. The IRLG creates innovations, supports companies, and collaborates with stakeholders in economy and politics to ensure knowledge transfer towards a digital society. IRL Dresden has a particular focus on detection, localisation, and mitigation of interference and improving network resilience through real-time measurements of time-variant channels and cooperative spectrum sensing. Norman Franchi, project lead at IRL Dresden, said: “The capabilities to cope with predictable as well as unpredictable disturbances and to provide appropriate self-optimisation and self-healing mechanisms are still insufficient. Automated
and reliable methods based on real-time measurements and AI analysis to detect, localise and avoid unintentional self- interference as well as intentional interference like jamming are becoming increasingly important and challenging. This is especially true in dynamic industrial use cases and communications scenarios. The goal of the cooperation is to analyse and evaluate the requirements on the measurement sensors and network, and to derive which real-time performance can be achieved.”
Anne Stephan, vice president mobile network testing at Rohde & Schwarz, said: “Industrial campus network deployments, whether based on private spectrum or provided through network slices from a public operator, generally establish a demanding use case scenario. By partnering with a research institute like the IRL Dresden we not only support fundamental research, but gain first- hand insights that we can use to adapt our leading mobile network testing solutions for Industry 4.0”
DATA MODUL presents its own SMARC module D
ATA MODUL is expanding its SMARC product family in the embedded sector and presents the eDM-SMX-EL, a compact, powerful SMARC 2.1 module
that supports the new Intel Atom x6000E, Pentium and Celeron N & J series processor generation (codename Elkhart Lake). Thanks to the improved graphics performance of the processor, the new module can support three independent displays with a resolution of up to 4Kp60, making it ideal for a variety of graphics-intensive low- power IoT applications.
Compared to its predecessor, the new credit-card-sized eDM-SMX-EL increases CPU performance by more than 40 per cent, graphics performance by a factor of two and, with up to four cores, offers an excellent performance/watt ratio (4.5W - 12W TDP). In addition to the usual controller interfaces such as CAN, the module has a dual GbE with TSN to ensure real-time capable device communication. In addition, there is a large increase in data throughput thanks to the PCIe Gen3 (8 GT/s) and USB 3.1

Gen2 (10 Gbit/s) interfaces. Also noteworthy is the up to 16 GByte LPDDR4X working memory with a speed of 4267 MT/s. With the In-Band ECC feature, which can be configured in the BIOS, no additional memory is required; instead, part of the RAM is used for this purpose. This means that the customer can dispense additional memory and save costs.
“The new eDM-SMX-EL module is aimed at system developers who are looking for SoC-based COMs with particularly low power consumption in a miniature
format,” explained Richard Pinnow, head of product management for embedded solutions at DATA MODUL “The small footprint, high flexibility and cost- effectiveness of our SMARC 2.1 module will be a game changer for many industries and applications in the field of edge computing.”
Components in Electronics
The module is designed to operate in the full industrial temperature range of -40°C to +85°C. This, combined with its low height and high performance, allows the eDM-SMX- EL to be used in many multimedia and IoT applications. In addition, the module has very low maintenance requirements thanks to its extremely long service life of 10 years even
in 24/7 continuous operation. For a quick design start and the shortest possible time- to-market, the module can also be combined with the SMARC carrier board eDM-CB-SM- IPCS recently introduced by DATA MODUL. The board has a V-by-One interface, which means that high-resolution displays with a resolution of up to 4k can be operated.
