Quick guide: Which DECT solution fits your business


DECT solutions from Snom and Sangoma


DECT stands for Digital Enhanced Cordless Telecommunications and is a European standard for cordless phones. This standard was firstly used in homes but thanks to the fact that the cordless phones allow mobility they were accepted in business uses.


The frequency band DECT solution use is 1.88 - 1.9 GHz in Europe. This is a dedicated band and it is not as crowded as Wi-Fi and Bluetooth the frequency bands, so there is no interference.


Unlike mobile services, DECT solutions don’t depend on the service provider for the quality of service, they depend on themselves. Also, cordless phone’s battery last much longer than the smartphone’s. Compared to smartphones cordless phones are more durable and resistant.


DECT solutions consist of a base station and one or more cordless phones.


Base stations can be single sell or multi cell. The difference between the two is in the number of cordless phones they support. While single cell base stations usually support 4-6 phones (some even 20), multi cell base stations can support up to 1000.


Base stations have an indoor range of up to 50m and, in theory, up to 300m outdoor. Single cell base station’s range can be expanded by adding repeaters, while multi cell’s by adding one or more base stations and repeaters.


DECT base stations

Which base station works for you depends on how many users you have and how large and structured your business premises are.


For smaller businesses, small in terms of number of employees and office space, there are several single cell base stations to choose from – two from Snom and one from Sangoma.


Note: Both single cell and multi cell Snom base stations operate at frequency bands 1880-1900 MHz for Europe, 1910-1930 MHz for Latin America and 1920-1930 for the US. Sangoma base station operates at frequency bands 1880-1900 MHz for Europe and 1920-1930 for the US. Snom DECT solutions are compatible with all major IP PBXs while Sangoma DECT is designed exclusively for FreePBX and PBXact UC.

If you are in need of extending the range of M300 you can do so by adding M5 repeaters. M5 repeaters don’t require Ethernet, they are installed by registering on a DECT base. The repeater acts as a base station in terms that it allows seamless and uninterrupted calls when a person exits base station range and enters the repeater’s.
