Evaluation of Channel Capacity of Millimeter-Wave WBAN Considering Human Body Blocking in User-Dense Condition

Millimeter-wave (mmW) wireless body area network (WBAN) is effective as one of the methods to reduce inter-WBAN interference even in user-dense conditions because of human body blocking. In this paper, we evaluate intra-WBAN channel capacities in user-dense situation considering the inter-WBAN interference model by using elliptic cylinder approximation of the human body. We obtain the result that the intra-WBAN channel capacity of over 50 Mbit/s at cumulative distribution function (CDF) of 0.1 was ensured with the system bandwidth of 100 MHz, even in the case of a high user density of 200 users/100m2 by the computer simulation.
