Wi-Fi signals experience attenuation due to distance from their source just like any other radio. This signal attenuation subsequently causes the radio to be less effective and throughput suffers. Eventually, connectivity is lost when the signal becomes too weak. There are essentially two factors that affect signal attenuation between the access point and the client, and those are range (or distance), and attenuation due to obstructions
