Sectorised Antennas (SA) integrated with low power technologies have lead to signiﬁcant improvement on Localization Systems (LS) performance. A SA specially designed for localization purposes is the Hive5, a platonic pentagonal patch-excited SA. This paper presents the developed ﬁrmware and management application of an LS integrated with the Hive5. This LS performance is then compared to a typical Wireless Sensor Network (WSN) LS based on four nodes. Both solutions are analyzed within the same localization environment and compared to the same supporting ﬁngerprinting algorithm, an Artiﬁcial Neural Network (ANN). Results show that LSs integrated with the ive5 present clear beneﬁts when compared to the WSN of four nodes in terms of
resolution and obvious reduction of required reference units.
