	1586	+The cellular module used by the DLOS8N gateway is EC25-E, an LTE Cat 4 module launched by Quectel Communications. It supports 4G networks and is also compatible with 3G and 2G.
	1587	+
	1588	+
	1589	+Users can access the gateway CLI and run the minicom command to get the configuration interface.
