Dictionary of Computer and Internet Terms: wireless cloud
wireless cloud
the irregularly shaped area in which a wireless networkis usable. Because radio waves fade out gradually with increasing distance and penetrate some kinds of obstacles better than others, the size and shape of the wireless cloud depends both on the environment and on the equipment at both ends of the link. Better antennas give greater range.A would-be intruder with a special antenna can access a wireless network from ten times the normal distance.
