EVDO
EVDO
1xRTT
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
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.
GSM Bearer Types (Used for International Roaming)
GSM Bearer types include the following:
HSUPA and HSDPA
HSUPA (High Speed Upload Packet Access) and HSDPA (High Speed Download Packet Access) are the upload and download components of the HSPA protocol suite. If your device reports that it is using one of these, the other is almost certainly being used as well. These are fast 3G bearer types that directly compete with fast CDMA bearer types like EVDO and may eventually reach speeds comparable to 4G.
UMTS
UMTS (Universal Mobile Telecommunications System) may refer to a number of 3G technologies, including HSPDA and HSUPA at the faster end as well as a few other 3G technologies that might be slightly slower.
EDGE
EDGE (Enhanced Data rates for GSM Evolution) is a 3G bearer type whose maximum download speed in the vicinity of 200 kilobits per second, depending on network configuration.
GPRS
GPRS (General Packet Radio Service) is a 2.5G bearer type for GSM networks. It's limited to a maximum download speed of around 60 or 80 kilobits per second, depending on network configuration.
