    This is why this modern telephone technology is in high demand. Its use is widespread in communication systems in homes, offices, and industrial settings.

    How it Works?

    A DECT system consists of (at least) two parts: the base station and the mobile phone. These two parts are in constant communication with each other.

    The base station receives data (such as incoming calls) and sends it to the handheld. When you speak into the mobile phone, this data is transferred back to the base station and so on from there.

    Several base stations can be linked together in a network to cover a larger area, for example, in large buildings.

    When information is transmitted from the mobile phone to the base station, there may be an average delay of 10 ms, which in practice is much better than transmission via Wi-Fi or Bluetooth.

    Today, DECT devices must be Generic Access Profile (GAP) ready. This is a standard that allows DECT devices from different manufacturers to communicate and work together. 

    However, the GAP standard only covers basic phone functions. Therefore, mobile phones from other manufacturers may not be able to perform all the functions described when used together with other manufacturers’ mobile phones.

    DECT Applications in Daily Life

    The modernization and advantages offered by DECT technology have led to its widespread use for both personal and business purposes. Some common applications of DECT phones include:
