Interference among co-channel users is a fundamental prob- lem in wireless networks, which prevents nearby links from operating concurrently. Directional antennas allow the radiation patterns of wire- less transmitters to be shaped to form directed beams. Conventionally, such beams are assumed to improve the spatial reuse (i.e. concurrency) in indoor wireless networks. In this paper, we use experiments in an indoor office setting of Wifi Access points equipped with directional antennas, to study their potential for interference mitigation and spatial reuse. In contrast to conventional wisdom, we observe that the interference mit- igation benefits of directional antennas are minimal. On analyzing our experimental traces we observe that directional links do not reduce inter- ference to nearby links due to the lack of signal confinement due to indoor multipath fading. We then use the insights derived from our study to de- velop an alternative approach that provides better interference reduction in indoor networks compared to directional links.
