Correct Answer: Wi-Fi technology is a technology used for transmitting a signal using the 80211 specifications works a lot like it does with a basic Ethernet hub: They’re both two-way forms of communication, and they both use the same frequency to both transmit and receive, often referred to a half-duplex WLANs used radio frequencies (RFs) that are radiated into the air from an antenna that creates radio waves These waves can be absorbed, refracted, or reflected by walls, water, and metal surfaces, resulting in low signal strength So because of this vulnerability to surrounding environmental factors, it’s pretty apparent that wire-less will never offer us the same robustness as a wired network can, but that still doesn’t mean we’re not going to use or run the wireless or Wi-Fi
