FEM propagation indoors at an intermodal land terminal

This paper presents the impact of FEM propagation indoors at an intermodal land terminal. A specific base station layout design is presented, and a DECT system architecture is proposed.1. INTRODUCTION
So far, propagation conditions and the associated FEM power attenuation have been considered for outdoor channels (the open space of a land terminal in the article titled “FEM propagation in areas with complex architectural structures – intermodal land terminal”)[5]. Estimating propagation characteristics inside buildings is also very important, especially when designing wireless systems with base stations located indoors. [1]In the case of an indoor channel, the distance between the transmitter and the receiver is significantly smaller than for an outdoor channel. This is a result not only of the building’s geometric parameters but is also forced by low transmitter power and strong attenuation caused by internal walls and furniture. These factors have a major impact on the length of the channel impulse response. Such channels are characterized by significantly shorter delay spread than in the case of outdoor channels. (…)
