IEEE Communications Magazine, considered by most to be their most important member benefit, provides timely information on all aspects of communications: monthly feature articles describe technology, systems, services, market trends, development methods, regulatory and policy issues, and significant global events. These articles are complemented by a variety of departments, including: Conference Calendar, Book Reviews, the Global Communications Newsletter, Scanning the Literature, New products and Product Spotlights, Society News, Your Internet Connection, News from JSAC, and the CommuniCrostic puzzle. Articles are tutorial in nature and written in a style comprehensible to readers outside the specialty of the article. Mathematical equations are generally not used (in justified cases up to three simple equations may be allowed with the consent of the Guest Editor. The inclusion of more than three equations requires permission from the Editor-in-Chief).
