A Wideband Channel Model for Body Area Networks in Circular Metallic Indoor Environments

In this paper, the wideband characterization of propagation channel in circular metallic indoor environments is addressed, regarding Body Area Networks and 5G small cells, an analytical model for dependence mean delay average spread on circle radius, working frequency distance between transmitter receiver being proposed. The derivation initially done analytically, based optical physics, after which simulation results allow to obtain values coefficients. simulator was previously assessed with measurements at 2.45 GHz a passenger ferry room shape. For random positioning receiver, given them, it observed that increase linearly radius; furthermore, increases quadratically distance, while has concave parabolic behavior, maximum equal radius. practical case, Access Point inside room, recommended center, order reduce spread.
