Abstract
Embodiments of millimeter-wave communication systems and methods for communicating using millimeter-waves are described. In some embodiments, a directional antenna (102) may direct millimeter-wave signals substantially in a horizontal plane (115), and one or more reflectors (104) may be positioned to reflect the millimeter-wave signals to user devices (108).

11. A millimeter-wave communication system comprising:
-
a directional antenna positioned above obstacles in an indoor area to communicate millimeter-wave signals with a substantially secant-squared (sec2) pattern in a vertical plane and a substantially omnidirectional pattern in a horizontal plane to one or more user devices; and a base station to generate the millimeter-wave signals, wherein the directional antenna provides at least two sectors in the vertical plane and a plurality of sectors in the horizontal plane. - View Dependent Claims (12, 13, 14)
