Indoor localization has been an active research area for the last two decades. A great number of sensors have been applied in the task of localization, some with high computational and energy demands, like laser beams, or with issues related to the coverage area, for example, by making use of images obtained by a network of cameras. A different approach, that presents less energy demands and a wide area of coverage, can be created by means of signal strength of wireless networks. The open issue with signal strength is it high instability due to interferences, at- tenuation and fading; which, in general, makes the localization systems to present less than desired accuracy. In this article we exploit the use of Convolutional Neu- ral Networks (ConvNets) in the task of localization. The main motivation behind the employment of ConvNets is its inherent ability of feature extraction, which we believe can deal better with the noise without a filtering step. We evaluate how ConvNets can be employed and which are the best topologies that lead to the lowest errors.
