Indoor high-resolution channel characterization

Future communication systems will utilize multiple antennas and beamforming to a larger extent than what has been done before. Design and evaluation of systems with many antennas and large bandwidth requires channel models with good accuracy in angle and delay. An angular resolution down to one degree, and bandwidths of several GHz, are foreseen for the future 5G wireless systems. For this purpose, an indoor channel measurement campaign has been conducted at 58.7 GHz providing reliable and accurate direction information by massive spatial channel sampling and offline FFT processing.
