Introduction to Wide Band Millimeter Wave Communication Systems
In this article, we reason why the wireless community should start looking at the 3-300 GHz spectrum for mobile broadband applications. We introduce a millimeter-wave mobile broadband (MMB) system as a candidate for the next generation mobile communication system. We demonstrate the feasibility for MMB to achieve gigabit-per-second data rates at a distance up to 1 km in an urban mobile environment. A few key concepts in MMB network architecture such as the MMB base station grid, MMB inter- BS backhaul link, and a hybrid MMB + 4G system are described. We also discuss beam forming techniques and the frame structure of the MMB air interface.
