A simulation-oriented channel modeling methodology for human on-body channel communication

Human body channel, a candidate of PHY layer adopted by the latest IEEE standards (IEEE 802.15.6), has been investigated for applications with on-body communication. The study covers frequencies range from 100Hz to 1GHz and channel lengths from 65mm to 1.6m. After analyzing the measurement results, a suitable frequency range for body area network from 10 kHz to 10MHz was found. Channel model and corresponding modeling methodology are presented. Compared with the traditional models, the presented methodology allows an accurate model to be systematically constructed for either a specific subject or a group of subjects with similar physical forms and characteristics. The accuracy of prediction was proved by experimental validations (prediction error around 0.1 dB in frequency range from 10kHz to 10MHz).
