From focus is being paid to other

From multiple geolocation solutions available in the market, GPS does not perform well in indoor concentrations close to walls, buildings, high terrains, and in underground environment as the strong signals from GPS satellite loose intensity to cross adequately obstacles in the way making it ineffective for indoor localization that is the reason; focus is being paid to other technologies such as infrared-based positioning, ultra-wideband (UWB) positioning, radio frequency identification (RFID) positioning, and WIFI positioning, which are relatively suitable in indoor concentrations. However, most of them are only suitable for relatively small indoor compounds, and at a time when deployed to macro-scale fields; extensively underperform because of huge traffics of received signals from AP users, physical visiting of the area which is also time expensive even though mobile survey algorithm may replace
