Inter-Chip Wireless Communication Channel: Measurement, Characterization, and Modeling

Wireless Chip Area Network (WCAN) that realizes wireless interconnects within a chip (intra-chip) or among chips (inter-chip) represents a new development in wireless communications. WCAN features unique intra- and inter-chip wireless channels. This paper focuses on understanding of inter-chip wireless communication channels in computer cases. Inter-chip wireless communication channel is characterized for the first time based on measurements conducted in frequency domain inside a computer case on a laboratory workbench. A novel technique for doubling the time-domain resolution is proposed for converting the frequency-domain data to time-domain using Inverse Discrete Fourier Transform (IDFT).
