Roaming
In wireless telecommunications, roaming is a general term referring to the extension of connectivity service in a location that is different from the home location where the service was registered. Roaming ensures that the wireless device is kept connected to the network, without losing the connection. The term "roaming" originates from the GSM (Global System for Mobile Communications) sphere; the term "roaming" can also be applied to the CDMA technology. Traditional GSM Roaming is defined (cf. GSM Association Permanent Reference Document AA.39) as the ability for a cellular customer to automatically make and receive voice calls, send and receive data, or access other services, including home data services, when travelling outside the geographical coverage area of the home network, by means of using a visited network. This can be done by using a communication terminal or else just by using the subscriber identity in the visited network. Roaming is technically supported by mobility management, authentication, authorization and billing procedures.

Famous quotes containing the word roaming:
“When a lady of wealth, is seen roaming about in search of cheaper articles, or trying to beat down a shopkeeper, or making a close bargain with those she employs, the impropriety is glaring to all minds. A person of wealth has no occasion to spend time in looking for extra cheap articles; her time could be more profitably employed in distributing to the wants of others. And the practice of beating down tradespeople, is vulgar and degrading, in any one.”
—Catherine E. Beecher (1800–1878)
“Taught from their infancy that beauty is woman’s sceptre, the mind shapes itself to the body, and, roaming round its gilt cage, only seeks to adorn its prison. Men have various employments and pursuits which engage their attention, and give a character to the opening mind; but women, confined to one, and having their thoughts constantly directed to the most insignificant part of themselves, seldom extend their views beyond the triumph of the hour.”
—Mary Wollstonecraft (1759–1797)
