# Frequency bands
The electromagnetic spectrum is divided into smaller radio frequency bands (also called operating bands) that governments allocate to MNOs or private network owners. The supported frequency bands depend on:
* Operators – restricted to bands they own or have licensed for use in a particular country
* IoT devices – designed to work on a subset of all of the available operating bands

Eseye's solution can, in principle, work with any spectrum. However, to date, Eseye's solution has been focused on cellular connectivity.

### Identifying bands used by operators in specific countries
Frequency bands vary by country and region, and their allocation depends on the MNOs and other spectrum owners (such as CBRS for private networks). Eseye works closely with local MNOs to ensure the maximum number of connectivity options in each country.
The following table details the most common regions we support. Band usage can vary within countries owing to specific carrier deployments. Additionally, countries may introduce newer bands. Always check with your specific carrier or regulatory authority for the most up-to-date information about the region where you are deploying your IoT devices.

Alternatively, use the following resources to identify the frequency bands supported by an operator in a particular country:
* GSMA records of members and the licensed bands available to each
This information is only available to GSMA members.
The map does not contain the most up-to-date information.
Modem manufacturers can be aware of networks operating on two bands but choose to support only one band to reduce the modem cost. We recommend that you ensure your modem supplier provides documentation to show that the modem has access to all the frequency bands in each country of operation.
