The term “digital twin” has been called everything from just hype to a revolutionary concept. We use a jet engine example to explain the concept of digital twins and how simulation fits in.

The 5G mobile network and Internet of Things (IoT) are two hot topics in the RF and microwave industry. New developments in these wireless applications call for much higher data rates, active electronically scanned arrays (AESA), phased array antennas, and multiple-input-multiple-output (MIMO) technology. It is important to reduce the time and cost during the process of prototyping and manufacturing these applications. Using simulation and apps, we can streamline the development cycle of wireless communication designs.

As you leave for work, your garage door closes and texts your office coffeemaker to start brewing a fresh pot. During the day, your sprinkler system gets a weather report that it’s going to rain and cancels its afternoon watering. This isn’t a futuristic television show, it’s the Internet of Things, and with the next generation of wireless communication, 5G, it’s coming soon. First, we need to optimize the performance of existing mobile device antennas.

Check out a tutorial model with implications in developing the 5G mobile network: Butler matrix beamforming networks, which can be combined with phased array antennas for wireless communication.

Think about the “ideal” wireless network. Data would download at ultrafast rates. We could be connected anywhere in the world and expect quality performance every time we use our devices. An ideal wireless network would be, above all, reliable — no dropped calls, undelivered messages, or waiting for a web page to open. To meet the specific performance requirements of this ideal network, 5G, there are certain RF designs that engineers can consider to transform such technology into a reality.
