Abstract

As cellular network users continue to grow; there is a need for in-creased user capacity, higher throughput and improved system performance. An important issue affecting cellular networks is to make services available to re-gions of bad or no reception. Various standards and techniques such as, anten-nas, relays and hotspots are used in achieving this and one of the most reliable is a technique that involves bringing the transmitter and receiver closer to each other. This enhances the performance of the receiver by ensuring a high quality link. In this context, Femtocells are another promising technology to improve indoor coverage; these are short range low-powered base stations and usually installed by home users. However, the statistical analysis retrieved by deploying femtocells on a large scale does not reflect the behavior of a single femtocell. Moreover, the interference mitigation techniques employed take into considera-tion densely deployed FAPs which is not applicable in a scenario where there are only a handful of femtocells. This paper examines the influence of LTE-femtocells on a small scale in an indoor to indoor environment by comparing two well known path loss models ITU-R and WINNER II. To achieve this, a site specific scenario is modeled to investigate pathloss, received power, and SINR to show the behavior of a single femtocell as it experiences the abrupt fluctua-tions under the influence of co-tier interference.
