The global bandwidth shortage facing wireless carriers has motivated the exploration of the
underutilized millimeter wave (mm-wave) frequency spectrum for future broadband cellular communication
networks. There is, however, little knowledge about cellular mm-wave propagation in densely populated
indoor and outdoor environments. Obtaining this information is vital for the design and operation of future
fth generation cellular networks that use the mm-wave spectrum. In this paper, we present the motivation
for new mm-wave cellular systems, methodology, and hardware for measurements and offer a variety of
measurement results that show 28 and 38 GHz frequencies can be used when employing steerable directional
antennas at base stations and mobile devices.
