Global Optimization of Indoor Radio Coverage

Abstract: Original scientific paperThe new focus of wireless communication is shifting from voice to multimedia services. There is a growing interest in providing and improving radio coverage for mobile phones, short range radios and WLANs inside buildings. The need of such coverage appears mainly in office buildings, shopping malls, train stations where the subscriber density is very high. The cost of cellular systems and also the one of indoor wireless systems depend highly on the number of base stations required to a… Show more

“…By implementing the proposed solution, the central controller identifies the coverage hole by detecting unexpected low RSS measured by certain sensors. Then the central controller will increase the weight of sensors in the coverage hole in cost calculation (1). And the selfhealing function will search for the optimized power setting for neighboring APs to achieve temporary coverage to the hole.…”

“…A lot of research has been carried out on coverage optimization for WLAN. In [1], the authors have presented the general discussion on coverage optimization for WLAN. Many works have been done on coverage optimization by optimizing Access Point number and location, such as [2], [3] and [4].…”

“…A second group of works extend the previous methods to indoor scenarios. In some of them, the APP is formulated to minimize path loss (or maximize coverage) with a general-purpose optimization algorithm (e.g., genetic [34], direct search [35], simulated annealing [36] or heuristic [37]). Similarly to [29], [38] proposes binary integer programming to find the minimum number of access points guaranteeing a minimum SINR in the scenario.…”
