soft handoff - Computer Definition
In cellular radio networks, a handoff process in which the connection is established by the second base station (BS) before being broken by the first as a mobile station (MS) moves out of the range of the first and into the range of the second.This technique is also known as make and break. See also BS, cellular radio, handoff, hard handoff, MS, and radio.
In CDMA cellular phone systems, a smooth transition from one cell to another. Unlike analog FDMA and digital TDMA systems, which use different frequencies in adjacent cells, CDMA uses the same frequencies but codes each conversation differently. As you move between cells, a CDMA phone picks up the same coded signal on the same frequency from both cells. When the original cell stops transmitting, the phone is already receiving the signal from the new cell causing a smooth transition with less chance of a dropped signal. See CDMA.
