1xRTT (1 times Radio Transmission Technology) is the most basic bearer type for 3G
CMDA networks. It is usually limited to download speeds of 144 kilobits per second.
Because of its limited (slower) nature, it is sometimes referred to as a 2.5G technology.

QNC (Quick Net Connect) is a 2G bearer type. As one of the earliest protocols for
transmitting digital data over CDMA networks, it is capable only of relatively slow
download speeds of 14.4 kilobits per second.
