  18. 18. Speed 3G 4G 2G AT&T’s GSM Network Technology LTE: LTE, or Long Term Evolution, is a fourth generation (4G) technology standard under development that will provide significantly increased peak data rates. EDGE: EDGE stands for Enhanced Data GSM Environment and is a digital mobile phone technology that allows increased data transmission rates and improved data transmission reliability. EDGE is often called 2.5G GPRS: Short for General Packet Radio Service. It is a standard for wireless communications which runs at speeds up to 115 kilobits per second. HSPA/HSDPA/HSUPA: HSPA, or High Speed Packet Access, is a general term that encompasses both HSDPA and HSUPA, which increase downlink and uplink speeds for AT&T’s 3G network, respectively. UMTS: Universal Mobile Telecommunications System, UMTS, is a GSM-based third generation (3G) cell phone technology, which is also being developed into a 4G technology, HSPA operates over UMTS.
