Device-to-Device Radio Link Analysis at 2.4, 3.4, 5.2, 28 and 60 GHz in Indoor Communication Environments

摘要

Device-to-device (D2D) communication has become one of the major areas of research ever since the industry was advancing to LTE and 5G. In this nascent stage of transformation, this research work characterizes the radio link behavior of D2D communication network in an indoor environment utilizing licensed and unlicensed band experiments and ray-tracing based simulations at frequencies of 2.4, 3.4, 5.2, 28 and 60GHz. The path loss exponent (PLE) and standard deviation are estimated and compared with free space path loss (FSPL), log normal shadowing (LNS), International Telecommunication Union (ITU) model and also, compared with other research works. This work also studied the impact of indoor environments on D2D communications along with link budget, channel capacities and required performance improvements.
