In this talk, the design dilemma of “What will be different between near-field communications (NFC) and far-field communications (FFC)?” is addressed from four perspectives. 1) From the channel modeling perspective, the differences between near-field and far-field channel models are discussed. 2) From the performance analysis perspective, analytical results for characterizing the degrees of freedom and the power scaling laws in the near-field region are provided for both spatially discrete and continuous-aperture antennas. 3) From the beamforming perspective, far-field beamforming is analogous to a “flashlight” that enables beam steering, while near-field beamforming can be likened to a “spotlight” that facilitates beam focusing. 4) From the application perspective, new designs are discussed in the context of promising next-generation technologies in NFC.
