portability

1. The quality of being easily movable from one physical place to another. In the context of transmission systems, wireless technologies offer the advantage of portability. Radio systems and free space optics (FSO) systems are inherently somewhat portable, and many are lightweight, collapsible, and otherwise specifically designed to be highly portable. RF (Radio Frequency) systems operating in licensed frequency bands must be licensed in each geographic area in which they are intended to operate. See also mobile and wireless. 2. Referring to the ability to move a telephone number from one carrier or service provider to another in a competitive environment. See number portability.
