This chapter presents an overview on the drivers behind the 5G evolution and explains technological breakthroughs in the microwave and millimeter wave domain that will create the 5G backbone. Extensions to millimeter wave frequency bands, advanced multi-antenna systems and antenna beamforming and simultaneous transmission and reception are some of the prospects that could lead to both architectural and component disruptive design changes in the future 5G. 5G is expected to include an innovative set of technologies that will radically change our private and professional lives, though applications of novel services, such as remote healthcare, driverless cars, wireless robots and connected homes, which will alter boundaries between the real and the cyber world.
