This paper introduces a wireless access system for the wide area ubiquitous network (WAUN), which is a large cell-based public sensor network, and provides feasibility study results gained through field tests. The wireless access system uses several key technologies to accommodate widely dispersed small simple terminals. First, to realize the large cell radius of several kilometers, space and site...
A lightweight phantom is made by a plastic shell with a shape of the human head and it has a cavity inside. The cavity is filled entirely or partially with the absorbers. In the next section, we evaluate the characteristics of the phantom with a dipole antenna near a COST244 spherical model imitating the human head. The radiation patterns are measured in experiment, and the phantom is compared with...
