SWAN is the largest of all the ducks and usually stays with his partner all his life.

The SWAN2 is a wall or pole mounted, battery operated gateway and directly links up to 250 wireless M-Bus-devices to the cellular network using the new LTE Cat NB1 technology and additionally/ optionally supports the wired interfaces L –Bus or RS 485.

Provisioning takes place using a NFC interface, thus allowing to use your smart phone during installation. The same holds for the process of firmware update. In addition, remote configuration and FOTA (Firmware-Over-the-Air) can be performed over NB1 soon.

The OMS 3.x and 4.x compliant wireless M-Bus interface operates at 868 MHz and supports mode S, T and C, frame formats A and B.

The following protocols are supported: UDP, HTTP/S, LwM2M.

SWAN2 is equipped with 2 C cells. The operating time of approx. 10 years depends on the frequency of the upload and collection process and the signal strength.

For permanent operation with available main supply, we offer the SWAN3 as a suitable variant.
