+The CAT M1 Modem uses specific LTE Bands. There are many bands supported by the radio, primarily to support many different carriers. Each carrier typically only supports one or two bands. If the radio is used in a known area with a known carrier, an antenna should be selected to match that band for the best performance. Known certified carriers and their bands are listed in the [https://www.u-blox.com/en/product/sara-r4-series#tab-documentation-resources SARA-R410M-02B certification and initial production] document.
