Wi-fi tracker system for persons and objects

摘要: The present invention refers to a new short-distance tracking system for persons or objects consisting in the use of Wi-Fi—emitting device (for example key fob) carried by person object be tracked, and Wi-Fi receptor smart mobile phone as tracker unit. Smartphones have function capable measuring intensity received signal. signal transmitted has constant frequencies within range established protocol IEEE 802.11 b/g/n (Wi-Fi), is identified unique SSID. In this way application running on can show distance specific emitting wireless example, fob), depending detected attenuation level. When increases, will an prompt user move towards direction which intensifies. As approaches device, intensify continue moving same direction.
