Band 66 frequency

Band 66 adds blocks G-J (AWS-3) and the unique AWS-4 block . AWS-1 and AWS-3 (blocks A-J) are paired bands, meaning phones transmit to towers on different frequencies from what towers transmit to phones on. This prevents interference.

AT&T’s agreement involves 20MHz of Band 66 spectrum , which Dish owns nationwide, along with 6MHz of Band 29 spectrum. These are both frequency bands AT&T phones already use; only AT&T uses Band 29. Provided you have a relatively recent phone, you won’t need to do anything to experience better speeds and coverage.

US 4G LTE carrier bands: the BIG picture That would be the 1900MHz band 2 (B2) for AT&T; the 1900MHz B2 together with 1700MHz AWS bands B4 and B66 for Verizon ; and pretty much the same combination of B2, B4 and B66 for T-Mobile. Those bands make the backbone of 4G LTE network coverage especially for urban areas.
