Sammanfattning: Location-aware technologies in combination with emerging wireless communication systems have revolutionized many aspects of our daily lives by means of applications within the commercial, public and military sectors. Ultra-wideband (UWB) and 5G stand out as emerging radio frequency (RF) based technologies that tackle the limitations of Global Positioning System solutions. The thrive in search for better accuracy involves improved ranging algorithms, higher transmission powers, network densification, larger bandwidths, and the use of cooperation among nodes in the network. However, practical implementations introduce communication related constraints. In this thesis, we study the trade-off between localization accuracy and communication constraints in terms of delay. This trade-off is investigated and quantified for two of the most rapidly…
