Abstract :
Sectorised antennas (SA) integrated with low-power technologies have lead to significant improvement on localisation systems (LS) performance. A SA specially designed for localisation purposes is the Hive5, a platonic pentagonal patch-excited SA. This study presents the developed firmware and management application of an LS integrated with the Hive5. This LS performance is then compared with a typical wireless sensor network (WSN) LS based on four nodes. Both solutions are analysed within the same localisation environment and compared with the same supporting fingerprinting algorithm, an artificial neural network. Results show that LSs integrated with the Hive5 present clear benefits when compared with the WSN of four nodes in terms of resolution and obvious reduction of required reference units.
