Roaming -- The ability to access a network anywhere and
move freely while maintaining an active link through a wireless connection to a network.
Roaming usually requires a handoff when a node (user) moves from one cell to another.

T-1
1 Bell technology referring to a 1.544 Mbps
communications circuit provided by long-distance carriers for voice or data transmission
through the telephone hierarchy. Since the required framing bits do not carry data, actual
T-1 throughput is 1.536 Mbps. T-1 lines may be divided into 24 64 Kbps channels. This
circuit is common in North America. Elsewhere, the T-1 is supersede by the ITU-TTS
designation DS-1. 2.. A 2.054 Mbps communications circuit provided by long-distance
carriers in Europe for voice or data transmission. 1. Bell technology referring to a 1.544 Mbps
