M900 DECT Multi-Cell Base Station

With the new M900 base station, we are opening a new chapter in professional and modern multi-cell DECT technology.

The new easy-to-use base station comes not only in a completely new design, but also with new, versatile functions. In addition to an integrated DECT manager, the M900 also offers DECT and LAN synchronization. The integrated DECT manager manages all base stations in one installation and ensures constant availability and seamless handover. This means that calls are seamlessly transferred between the individual base stations - even across floors or buildings.

Security is a top priority in daily business communication. With the integrated TLS encryption, the M900 base station also sets absolute standards in terms of encryption.

Extreme scalability

The new M900 DECT base station provides a solid foundation for any installation size. From a small office with only one base station up to, for example, a hospital with several thousand devices, the integrated DECT manager housing state-of-the-art technology, can enable individual installations comprising up to 1,000 base stations and up to 4,000 handsets. Thanks to the M900 base station, the maintenance of the devices can also be carried out easily and efficiently. Each base station can wirelessly send software updates to the connected handsets, greatly reducing the workload for the IT department.
