On Demand: How Simulation Enables 5G Connectivity in the Industrial Environment

Learn how robust electromagnetic simulation and industry workflows are used to design and optimize 5G networks for smart, reliable and safe manufacturing environments.

Modern high-tech factories are large, complex and dynamic environments which require ultra-reliable high performance wireless communication networks to make them “smart”. Substantial challenges are also posed by having to accommodate multiple communication standards, operating across multiple frequency bands – 5G for example has sub-6 GHz and mm-wave frequency specifications. Catering for multiple standards may result in interference between radio systems.

Electromagnetic simulation is an essential tool for the design of a robust wireless communication infrastructure. This virtual workshop will discuss the simulation techniques and workflows required for antenna and array design, and for analyzing and resolving the interference issues. Different simulation techniques are required, depending on the application. When considering placement of antennas in large environments like the factory, hybrid-solver techniques are required for dealing with challenging multi-scale problems.

In addition, the workshop will demonstrate how to evaluate human exposure to electromagnetic fields to help meet applicable standards and ensure a safe working environment in which electromagnetic exposure is kept below legal limits.

Webinar: Elevate Performance of Your Antennas with End to End Design and Simulation

Optimizing the performance of aircraft communications systems is not getting easier. The challenge is compounded by the ever-increasing number of antennas installed on modern aircraft, the wider use of spectrum to support higher data rates, and the tightening of competing design requirements. For example, emphasis on fuel efficiency, demands that antennas have minimal impact on aerodynamic performance. We can expect airspace to become denser, with the proliferation of drones and air taxis. Combining this with dependence on flight automation underlines the imperativeness of reliable communication.

Digital design combined with simulation enables engineers to predict and optimize aircraft communication system performance. A complex multidimensional design space can be explored quickly using a digital twin, to identify the best design options, and minimize physical prototyping and testing.

In this webinar, we will analyze communication system performance for an open rotor concept design. We will cover all aspects of the workflow including; generating suitable antenna models for simulation, creating the aircraft/antenna model assembly, simulating installed performance using hybrid solver technology driven by DOE, combining antenna coupling with transmitter/receiver models to predict co-site interference.

Highlights:

• Rapid creation of antenna models for simulation
• Effortless antenna array modeling
• Installed performance analysis using DOE
• Co-site interference prediction and mitigation
• Powerful hybrid solver technology

Simulation Tools for Electromagnetic Interference

This post originally appeared on the Dassault Systèmes blog.

The world of electromagnetic devices is rapidly expanding, to include everything from smart devices in our homes to medical devices in and around our bodies. This technology is opening up many doors, allowing us to live more enriching and even healthier lives, but, like all good things, the technology comes with potential complications. When discussing electromagnetics, the term EMC/EMI often comes up. EMC stands for electromagnetic compatibility, which involves the unintentional generation and reception of electromagnetic energy. This energy can cause electromagnetic interference (EMI) and even damage in devices that unwittingly receive it.

EMC is the ability of an electrical system to properly function in its intended environment without influencing other devices, also known as giving off emissions, or being influenced by surrounding devices (known as immunity or susceptibility.) Emissions and Immunity is a well-regulated area, and compliance with these regulations is critical for all electromagnetic products.

In the past, EMC engineering was associated primarily with measurements, and could only be applied late in the design stage, as a physical prototype was required. If problems appeared, a great deal of effort was required in troubleshooting and applying countermeasures in order to pass rigorous testing requirements. Frequently, only the symptoms were addressed, with the underlying problem remaining undetected. This approach is cost-intensive and can potentially delay the time to market of the device significantly.

Simulation is a valuable tool in mitigating EMC issues, and can be used both during the design phase and during troubleshooting. Using it as early as possible in the design phase, however, has the potential to mitigate the need for later troubleshooting. Simulation can be used without a physical prototype, and can answer important fundamental questions such as whether to use a shielded or unshielded cable, for example. Beyond that, simulation gives access to information that is far beyond what measurement can offer, peering into the depth of products and evaluating the effects of even the tiniest of details.

CST Studio Suite contains a circuit simulator, which can be coupled with the full wave 3D electromagnetic simulation, offering unique possibilities for the user such as the ability to obtain field results that consider an attached circuit. It also allows the user to calculate field distribution at the speed of a circuit simulation as long as the geometry of the device is not changed, thereby greatly reducing the time and effort needed to evaluate a multitude of different circuit configurations and their effect on the system efficacy.

A tool called BOARDCHECK can be used very early in the design process to visually highlight potential problems and provide a list of all violations on a printed circuit board level. It is fast and easy to use, and is the first step in the process, after which 3D simulation can be run. Overall, CST Studio Suite provides a full spectrum of solutions for EMC/EMI simulation in a single, unified simulation environment. It offers support and openness to third party models and file types, such as CAD, PCB layouts, spice, IBIS, and more. It can be easily integrated into existing toolchains and offers a variety of solvers for different applications and use cases.
