Evaluation of channel capacity of millimeter-wave wireless body area network in overcrowded train

Abstract

Millimeter-wave (mmW) wireless body area network (WBAN) is effective in reducing inter-WBAN interference because of the large attenuation by human body blocking. In this paper, for evaluating the interference power and the channel capacity of mmW WBAN in consideration of the regularity of the arrangement of users, we proposed a user arrangement model which is assumed an actual overcrowded train. In the proposed model, the channel capacity was calculated in consideration of the user's shape, arrangement, and direction in the train. As a result of the computer simulation with the proposed model, it is concluded that the channel capacity of the overcrowded train environment with regularity in user arrangement varies more than that of a random environment.
