Growth in its end markets is being driven by factors such as the appetite for data to be transmitted faster and more securely, the upgrading of telecoms infrastructure around the world and the growing prevalence of private commercial wireless networks for voice and/or data communications linked to the industrial internet of things (IIoT).
