    4646The [https://www.u-blox.com/sites/default/files/SARA-R4-N4_ProductSummary_%28UBX-16019228%29.pdf u-blox SARA-R410M-52B] LTE Cat M1 modem supports M1 bands 2,4,5,12,13. For more info on the CATM1 standard and use cases see the following [https://www.u-blox.com/en/lte-cat-m1 CATM1 Explained Link].

     48CAT M1 is specifically for low power small data applications. Because of this, there are two items that help to reduce power:
     49 *
     50 * LTE PSM (Power Saving Mode)
     51 * LTE eDRX (Extended Discontinuous Reception)
     52  * This can be handy to disable if a lot of continuous data is required. It may help to disable eDRX (with the +CEDRXS command). In general, u-blox recommends disabling eDRX, which is currently default enabled in several of the +UMNOPROF profiles.
