Since its introduction, Digital Enhanced Cordless Telecommunications (DECT) has become an integral part of modern, everyday wireless telephone communication. This technology is widely sought after because it offers clear voice quality, security through digital encryption, energy efficiency, and a wider range.
Today, DECT remains the go-to wireless phone technology in many countries, including Indonesia. In fact, it has become the top choice for wireless communication at home and in the office.
In this article, we’ll discuss DECT technology as it applies to cordless phones—from the basics and how it works to its applications in everyday life.
Understanding DECT Technology
Digital Enhanced Cordless Telecommunications (DECT) represents an advancement in wireless communication technology. This technology uses radio frequencies in the 1.8 GHz to 1.9 GHz range, enabling clear voice communication free from interference from other devices such as Wi-Fi or Bluetooth.
The result is improved call quality and range compared to conventional telephone systems. DECT offers better connection stability, wider coverage, and higher communication security.
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:
- Households: Used for communication at home to help reach areas with poor cellular signal.
- Offices and small businesses: Used for communication among staff, eliminating the need to rely on mobile devices.
- Industrial or warehouse environments: These settings are ideal because they require long-distance communication without the hindrance of cables.
- Medical settings: Similar to offices and small businesses, hospitals and clinics use DECT phones for communication among medical teams.
What to Look for When Buying a DECT Cordless Phone
Now that you know how DECT phones are used in everyday life, you might be interested in using one. However, before you decide to buy one, there are a few things you should keep in mind.
- GAP compatibility: To access certain features, make sure that both the handset and the base station from different brands are GAP-certified.
- Range and Coverage: Look for models that support multi-base station networks to maintain stable range and coverage in large offices or multi-story buildings.
- Battery Life: Compare the talk time and standby time specified by the manufacturer with your actual daily usage.
- Number of supported handsets: Determine whether you’ll need additional units.
- Regulatory compliance: Ensure the device has passed type approval in the country where you’ll be using it to guarantee safety and prevent interference with other devices during use.
From this, we learn how DECT technology works and how it is applied in cordless phones. We also learn how it is used in everyday life.
Using technology that is constantly being updated is one way we can keep up with the times. However, don’t forget to use devices that are legal and meet a country’s certification standards.
