SWAN  is the biggest of the species of ducks and stays with his partner a lifetime.

The Narrowband IoT (NB-IoT) standard LTE-Cat-NB1 is a brand-new 3GPP licensed low-power wide-area network (LPWAN) radio technology for M2M communication over the existing LTE cellular infrastructure. This cost-effective solution for small data rates offers very high coverage and deep building penetration at low power requirements and long battery lifetime.

The SWAN directly links a wireless M-Bus device (e.g. an utility meter) to a user application server by means of the new LTE Cat NB1 narrowband cellular network technology.
It can easily be configured and paired with a wM-Bus device by connecting a common terminal program to the USB service port. The OMS compliant wireless M-Bus interface operates at both 868 and 915 MHz and supports mode S, T and C frame format A and B. Either synchronous or asynchronous receiving modes can be configured.
The gateway is available in versions for LTE band 5, 8 and 20 respectively. Both the Huawei/Neul-IoT and UDP protocols are supported. The raw and not decrypted wM-Bus data are uploaded in user configurable intervals.
