DECT is an acronym for Digital Enhanced Cordless Telecommunications and refers to a standard for the transmission of voice and data signals. DECT technology allows us to perform several functions: talk on the phone wirelessly in HD quality, listen to music, view images and read e-mails. It also allows the use of home automation devices and multimedia players in a simple and completely secure way.

DECT technology is mainly applied to cordless telephony wireless telephony This has led to numerous advantages and advances that have allowed its consolidation in the last decade. So much so, that in buildings and companies it has become a must, to the point of having such a wide offer that it is necessary to know in detail the functionalities and important details that make a phone stand out from the rest.

Operation of a DECT telephone

A DECT technology system is always composed of two interchangeable components: a fixed part, the base station; and a portable part, which is usually a telephone or, failing that, a handset. handset .

The base station serves as a bridge between the telephone and Internet connection and the terminal or terminals that are connected. According to the DECT Standard, up to 6 wireless handsets can be supported from a single base station. Generally, the fixed part we are talking about can be: a DECT base station with an answering machine (it does not always have this option) or a DSL router that contains the DECT function. In the first case, the DECT base station is connected to a telephone line (digital or analog) and regulates both the transmission and the voice connection via a radio point.

The telephone, handset or smart home sensor is the second element of this DECT telephone system. It is a wireless component connected to the base station that continuously transmits the so-called «beacon signal». This message can be received by a nearby terminal, displaying the information required to establish a connection and send data through the base station. When this happens, both members are synchronized and can make wireless calls.

The radio bands used in this type of system range from 2-GHz. This makes it possible to reach distances of up to 50m in enclosed spaces and up to 300m in open spaces. Despite this limitation, it is possible to extend the transmission power and reach greater distances by means of booster units.

Advantages

• High transmission power, expandable with booster units.
• High security in voice transmission thanks to encryption.
• High energy efficiency
• Use of its own frequency range, totally independent of Wi-Fi.
• Better sound quality.
• Possibility of simultaneous use of several devices.
• Internal calls.
• Adaptability of terminals to different base stations.
• Automatic switching between bases and terminals.

As already mentioned, the range of DECT telephones is more than wide, so here is a selection of the different terminals that we market and distribute of the renowned brand Motorola :

This technology has been implemented in companies and homes for more than 25 years and, for the time being, it seems to have a long way to go in this ecosystem. In this entry we have made a selection of DECT telephony, but if you need more information you can see our extensive catalog catalog y contact our experts in the field.
