Recommended LTE bands for new IoT product

Hi there,

We are supporting the development of a low-bandwidth IoT product (LTE Cat-M1) that will be deployed nationwide on the AT&T network.

We understand that LTE B2, B4 and B12 are the minimum bands required to be supported, but what other bands are recommended for this sort of application?

Thanks.

The LTE bands that are used and compatible with AT&T service is available with a simple Google search. Even Wikipedia has this information

Having compatible LTE bands does not mean AT&T will allow it on the network

See NETWORK

Understood. However, I am looking for insight as to which bands to prioritize, as AT&T likely has internal plans on which bands to continue to develop, which to purpose for specific niche applications (e.g., urban capacity adders like B7 vs. rural long-range bands like B12/17) and which are not commonly used. Each band supported adds certification costs for the product (PTCRB + AT&T IoT) and we are trying to be cognizant about how to prioritize them accordingly.

For anyone else with the same question, the response I received directly from AT&T was to support bands B2, B4 and B12 only for LTE-M applications.
