Presently, wireless technology for headsets fall into two major categories: DECT and Bluetooth. While it can be confusing to differentiate between the two, they however have distinct characteristics that set them apart with the main difference being the wireless range. This blog would be discussing this major difference as well as other differences. But first, let us establish what DECT and Bluetooth technology are.
Understanding DECT and Bluetooth Technology
DECT, or Digital Enhanced Cordless Telecommunication, is a long-range wireless technology that originated in Europe and is mostly utilised in cordless phone systems and accessories. DECT is designed to connect to a base station. This single base station powers numerous devices.
Bluetooth, on the other hand, is a short-range wireless technology with fast data transfer capabilities. One fun fact about this wireless technology is that it has become a standard connectivity option for most applications.
Wireless Headsets: DECT vs. Bluetooth
Wireless Range
DECT wireless range varies from around 160 feet indoors to about 980 feet outdoors, giving you the freedom to move within this range without losing connection. These stated ranges are based on ideal situations with no obstructions. Using DECT repeaters, the range can extend further to greater distances.
Bluetooth headsets offer a shorter wireless range, from about 125 to 130 feet and about 780 feet outdoors. However, it's important to note that barriers, such as walls and other intricate objects, can disrupt the Bluetooth signal, resulting in a shorter range.
Connection
DECT headsets require a dedicated base station connected to a telephone line or PC via a “physical cable” to provide the headset with a wireless connection. This limits the headset connection to just the base station. This type of connection is private, and it ensures a high grade of security and reliable connection, as the handset and base station work together, thus no way it can be hacked.
Bluetooth headsets connect directly to your device. While some models support pairing with up to eight devices, you can only connect to two simultaneously. You can use it with your PC, smartphone, and tablet. Although the pairing process could be easy, it is however open to third-party intrusion, and could be affected by interference and disconnection, especially when used in busy environments with a considerable number of individuals using Bluetooth devices.
Security
DECT uses a special frequency band, separate from other wireless communication protocols such as Wi-Fi and Bluetooth. As a result, DECT wireless headsets are less vulnerable to interference and hacking. In addition to the efficiency of DECT, it uses advanced encryption standards (AES) to protect communications between the headset and base station, ensuring high security. DECT headsets operate on 64-bit encryption.
On the other hand, Bluetooth headsets transfer bandwidth via the use of Frequency Hopping Spread Spectrum (FHSS) technology. Although FHSS offers some level of security, it is not as great as DECT's AES encryption. Bluetooth headsets use 128-bit encryption. Bluetooth is very susceptible to hacking and eavesdropping if care is not taken, which is why it is most advised to always turn off Bluetooth connection when not in use.
Battery Life
DECT and Bluetooth wireless headsets use rechargeable batteries, but their battery life varies. DECT headsets offer around 10 hours of talk time and can last up to 50 hours on standby. This is because the dedicated base station provides power to the headset when not in use.
Generally, Bluetooth headsets have an average battery life of around 4-6 hours for talk time and can last up to 100 hours on standby. However, recent technology offers headsets with 25 hours or more of talk time.
Still on battery life, Bluetooth headsets typically do not have a battery that can be replaced. This means that when the battery no longer holds a charge, you replace the headset. The same is not applicable to DECT headsets, as nearly all DECT headsets have a battery that can be replaced. However, more recent Bluetooth workplace headsets now include better battery technologies, including quick charging and extended battery life.
One point to note is that battery life can be affected by factors such as volume level, distance from the host device, and the headset’s battery capacity. So when using your headset, especially Bluetooth headsets, beware of these factors.
Our Verdict: DECT vs. Bluetooth
From the foregoing, you can see that these technologies - DECT and Bluetooth - though similar, have unique features that differentiate them. In making a choice, consideration should be given to your purpose - how you intend to use your wireless headset. A DECT headset may be just what you need if you operate in a fixed location and utilise a single desk phone. Bluetooth wireless headsets may be a better option for collaborative groups or those on the go. They can be paired with numerous devices at the same time, allowing users to seamlessly switch between computers, tablets, and smartphones.
