To affect our daily lives, a large number of popular wireless technologies can play an important role. Among the wireless technologies, the cell phone networks are the commonest ones. Moreover, as a short-range technology, Bluetooth pairs wireless devices to one another. Talking about wireless networking, the specific technology involved is Wi-Fi.
