Exponential growth in wireless service subscription and its corresponding data traffic prediction poses a threat to the current 4G system; this triggered next generation wireless system (5G) research to improve system data rate and the overall network capacity thus, gained attention. In addition to the high data rates, other key features essential for successful system deployment were proposed and addressed towards 5G framework using various disruptive technologies. These include: the millimeter-Wave, massive-MIMO, beamforming-beamsteering, and Heterogeneous Network. These features further prompt, reexamining the system design and performance trade-offs with the existing 4G wireless system. This article presents the system design, implementation, hardware prototyping for 5G system beamforming/beamsteering. Hardware prototyping uses National Instrument Software Defined Radio (NI USRP 2922) and array antenna for system performance analysis. Results obtained show improved performance with increasing antenna.
