About AT&T

AT&T Mobility is the second largest wireless communications services provider in the United States as of 2012. Originally known as Cingular Wireless from 2000 to 2007, the company went through a series of acquisitions and rebranding to become the new AT&T.

AT&T 3G Signal Boosters

AT&T’s 2G (GSM/GPRS/EDGE) and 3G (UMTS/HSPA) networks run on the same frequencies, both 800 MHz and 1900 MHz. These frequencies are the standard ones used in North America. Signal boosters that can amplify both of these standard frequencies are referred to as “dual-band” and are ideal for improving your AT&T reception.


AT&T’s 3G network was upgraded to HSPA+ technology in many areas which is faster than the original 3G network. Rather than continuing to call it 3G, AT&T decided to start calling this network 4G. If your phone says 4G and not LTE, you’re probably using this technology. Unlike 4G LTE, this faux 4G uses the same frequencies as 3G (since it is 3G) so you can use any of the standard dual-band repeaters.


AT&T’s LTE network uses the newly available 700 MHz spectrum, specifically 698 to 746 MHz. This slice of spectrum was previously used by analog broadcast television, but now is used for the AT&T high speed data network. If you would like to boost this network in addition to the 2G and 3G networks, then you'll need one of the tri-band or five band boosters.

Bottom Line

If you have a 3G phone, go with any standard dual band signal booster to improve your AT&T signal. If your phone says “4G” and not LTE, it’s likely using the 3G frequencies so the same dual-band signal booster will work. To boost a 4G LTE signal, you’ll need a tri-band or five band booster that will boost 2G, 3G and AT&T 4G LTE.
