Base stations

Gigaset DECT Schnurlostelefone sind mit verschiedenen Basisstationen kompatibel, die unterschiedliche Funktionen und Leistungen bieten. Dazu gehören sowohl die eigenen Basisstationen von Gigaset sowie die von anderen Herstellern wie z.B. AVM oder Telekom. Einige der Basisstationen sind universell einsetzbar, während andere speziell für Bestimmte Anwendungen entwickelt wurden. Ein Beispiel für eine universelle Basisstation ist die Gigaset GO BOX.


Handsets from Gigaset are generally compatible with all of the manufacturer’s handsets as well as with numerous DECT handsets from other manufacturers. However, there are exceptions, especially with older models. To make sure you choose the right combination of base station and handset or handset and handset, you should consult the compatibility list on the Gigaset website.

How to find the right combination

Step 1: Identify your needs

Consider what features and services are important to you in a cordless phone. For example, do you need a base station with an answering machine or are you looking for a handset with a large display and hands-free function? As Europe’s market leader, Gigaset offers the largest selection of suitable devices.

Step 2: Choose the right base station

Once you have identified your needs, you should select a base station that meets your requirements. Compare the different models Gigaset offers and pay attention to which features they support. For example, some base stations allow you to use Internet telephony (VoIP), while others offer additional security features.

What many customers do not know is that the range of DECT handsets can be significantly increased. Traditionally, it is said that a DECT handset from Gigaset can cover a good 60 metres indoors and up to 300 metres outdoors. However, if a house is built very solidly or the telephone connection is unfortunately installed in the basement, this range shrinks. Then a DECT repeater is worthwhile. This works in exactly the same way as a WLAN repeater, only for DECT.

Step 3: Choose the right handset

Now that you have chosen the right base station, it is time to find a matching handset. Make sure that the handset you choose is compatible with your base station. You can check this by consulting the compatibility list on the Gigaset website.

Also consider what features the handset offers, e.g. hands-free function, large display, user-friendly menu navigation or Bluetooth connectivity.

In the meantime, it is also possible to operate a DECT cordless telephone directly on a router. This eliminates the need for a base station. If the router has a DECT module, i.e. it can communicate with the handset via the air interface, the Gigaset HX handsets are recommended. These were specially designed for use with various routers, such as Speedport, Fritz!BOX or others.

How phones communicate: DECT, GAP and CAT-iq explained


DECT stands for “Digital Enhanced Cordless Telecommunications” and is a standard for cordless telephones that was originally developed in Europe. DECT phones offer a long range, good voice quality and security through encryption of calls. In addition, DECT allows you to use several handsets at the same time on one base station, so you can cover several rooms in your home or office. Gigaset played a key role in developing this standard and supplemented it with ECO-DECT technology, which is part of the company’s sustainability work.


GAP stands for “Generic Access Profile” and is a standard that allows DECT handsets from different manufacturers to work with base stations from other manufacturers. This means that you can, for example, use a Gigaset handset with a base station from another manufacturer as long as both devices are GAP-compatible. Note, however, that not all functions may be available when using devices from different manufacturers.


CAT-iq stands for “Cordless Advanced Technology – internet and quality” and is a further development of the DECT standard. CAT-iq offers improved voice quality through wideband audio, also known as HD telephony, as well as a higher data transmission rate that enables the integration of internet services such as VoIP telephony. CAT-iq-enabled devices are backwards compatible with DECT devices, so they can be easily integrated into existing DECT systems.

In summary, DECT, GAP and CAT-iq provide a reliable and flexible basis for cordless telecommunication, allowing you to combine devices from different manufacturers while benefiting from advanced features such as HD telephony and Internet telephony. By understanding these standards, you can make an informed decision about which Gigaset DECT cordless phones are best suited to your needs.


The compatibility of Gigaset DECT cordless phones allows you to find the ideal combination of base station and handset for your needs. By identifying your requirements and carefully comparing the different models, you can ensure you get the best solution for your communication needs.
