Telecommunications equipment, also called telecoms or communications equipment, is hardware used for telecommunications purposes, spanning switching systems, transmission infrastructure, and customer premises equipment such as smartphones, routers, and modems. The sector is highly concentrated: 2017 revenue data shows Huawei alone generating 92.55 billion dollars, followed by Cisco Systems at 48 billion dollars, Ciena at 38.57 billion dollars, Nokia at 27.73 billion dollars, and Qualcomm at 22.30 billion dollars, with the United States leading all countries at 94.62 billion dollars in combined revenue, followed by Japan at 62.52 billion dollars and Finland at 27.73 billion dollars. Most of the essential elements of modern telecommunications, including mobile devices, network infrastructure, and processing components, are built from MOSFETs, metal oxide semiconductor field effect transistors, and as of 2005 telecommunications equipment represented about 16.5 percent of the annual microprocessor market. The sector includes both established multinational corporations and specialized regional players such as India's HFCL.
