AT&T frequency information

AT&T 2G/3G frequency boosters

For 2G and 3G service AT&T uses a mix of the 850MHz and 1900MHz blocks. These are the same frequency blocks used by almost all US and Canadian networks, so almost any of our kits will boost these signals. A repeater that works on these frequencies is called "dual band", and so any "dual band" repeater you see on RepeaterStore will boost most voice, 2G and 3G in the US and Canada.

AT&T 4G LTE boosters

For 4G LTE AT&T primarily uses the 700 MHz LowerB/C Block. All of our repeaters marked as compatible with AT&T 4G operate on this frequency range - to filter and just see these products, you can click here. AT&T currently uses this frequency for super-fast 4G data, while voice, 2G and 3G continues to run on the "dual band" frequencies of 850/1900MHz.
