The SWAN2 is battery operated gateway and directly links up to 250 (SWAN2-C) wireless M-Bus devices to the cellular network using the new LTE Cat-NB1 technology.
The device is configured via the NFC interface. WEPTECH provides an Android application for this. This app also allows an update of the firmware of the device. In addition to that there is the option for remote configuration and Firmware-Update-Over-The-Air.
The wireless M-Bus interface (radio standard according to DIN EN 13757-4) works with 868 MHz and supports modes S, T and C as well as frame formats A and B. The gateway supports LTE bands 3, 8 and 20 as well as the protocols UDP, HTTP/S and LwM2M.
The device will switch to receive mode at adjustable intervals. The incoming wireless M-Bus meter telegrams are stored in a non-volatile memory. Following this or at configurable times, the data is sent via LTE Cat-NB1 mobile radio to the previously selected server.
