Choosing the Right Wireless Headset: DECT vs. Bluetooth

As you’re hunting around for wireless headset to go with your unified communications implementation (because, as we’ve discussed, a proper wireless headset is crucial to user acceptance), you’ll likely come across the DECT standard. You may find yourself wondering just what DECT is and how it differs from Bluetooth. This simple post will, hopefully, put the matter to rest.

DECT stands for Digital Enhanced Cordless Telecommunications, although it’s also known as Digital European Cordless Telecommunications – which makes sense because it’s a standard that originated in Europe. It is used to connect a cordless phone to a base station mainly on wireless phone systems. DECT is also used for various other applications, ranging from
baby monitors to industrial remote controls, but for our purposes, we’ll focus on the phone systems.

DECT is used for both consumer and corporate phones. In the latter case, it can be used with a PBX (IP- or TDM-based) and a wireless LAN, enabling users to move around an office without losing their calls.

The standard is widely used in or near the 1.9 GHz frequency band; however, it does not interfere with other wireless technologies including Wi-Fi and Bluetooth.


People are often concerned that others could tap into their phone call via a wireless connection; however, according to Dennis Majikas, a service engineer with Jabra, “That is almost impossible to do once authentication is established. There are two areas of potential concern, the first is when the headset to base authentication is established which includes a number of handshakes and allows for establishment of a secure link. Once that happens the wireless headset then turns voice into digital data, encrypts that, and passes only the encrypted data back to the base (for both standards), making the conversation highly secure.”

Majikas adds, “DECT uses 64 bit encryption, and Bluetooth has 128 bit encryption, so once the wireless headsets are appropriately paired with their base stations the chances of someone effectively listening in on a call is virtually nil.”

The Distance Dilemma

DECT offers a much greater range than Bluetooth. DECT has a range of about 100 meters, whereas, Bluetooth ranges from 1-30 meters (depending on its class).

  • Class 1 goes up to about 30 meters
  • Class 2 about 10 meters
  • Class 3 is 1 meter.

In an office environment, a Bluetooth-capable base station for a wireless headset would typically be Class 1. But a smartphone would be Class 2 so if the headset was to answer a call from the smartphone, it would automatically adjust itself to Class 2 power level. Class 3 is typically used for devices such as keyboards and mice.

Connectivity Considerations

Another difference is that a DECT wireless headset only connects to its base station to provide connection to the phone network. Multiple base stations can be placed throughout a facility, so if you go outside the range of one base station, it will seamlessly hop to the next base station in order to provide continuous connection without ever dropping a call.

On the other hand, a Bluetooth device can connect to up to 8 other devices simultaneously.  For example, a headset can be connected to a user’s mobile phone, computer-based soft phone and desk phone.

So the choice in wireless headset will largely depend on how it will be used. For office environments where users need it for their desk or computer-based phones, a DECT headset makes sense. The headsets will allow users to move around as much as needed.

On the other hand, if the wireless headset will also be used with a mobile phone, then Bluetooth may well make more sense. Mobility will be less of an issue since users have their mobile phones with them anyway, so they will likely remain within the 10-meter limit. The ability to use the same headset for both office and mobile phones is convenient. And if you’ve got a UC system that enables uninterrupted handoffs between computer-based softphones and mobile devices, that’s even better – the single Bluetooth headset should be all your users need.

How Can SIP Leverage Your Real Time Communications?

Every business depends on one or more communication channels for their regular business activities. For instance, one company might take to messaging frequently, while another might use video conferencing a lot. Unified Communications and cloud-based VoIP has offered a plethora of services for real-time communications, which facilitates smooth running business processes.

SIP for real time communications


Session Initiation Protocol (SIP)

If the communication technologies are not diverse and evolving on a regular basis then they will soon lose their relevance. SIP or Session Initiation Protocol is the most important technology that plays a vital role in IP telephony. SIP is the technology that facilitates one-to-one communication among callers by initiating many vital functions like call setup, authentication, routing and sending featured messages to the endpoints connected to the same IP domain.

Advantages of SIP

SIP is a protocol that helps the subscribers of different companies communicate seamlessly. It facilitates the leveraging of IP telephony by the users just like they would for other web applications. Integration of a variety of Internet services with IP telephony is also facilitated by SIP. Thus, this not only helps in establishing an integrated communication system, but it’s also the base for communications on a real time-basis.

Design of SIP platforms

SIP platforms are designed in a manner that they can be delivered both in the form of a hardware solution and/or a software system. This can then be integrated with VoIP so that the solutions can be leveraged to streamline communications and trigger quicker response time.

Mobility & SIP

Mobility is an area of concern for every company and all are trying to develop solutions that can support mobility. Cloud is thus the obvious choice for such businesses because it provides an infrastructure for both in-house as well as remote locations. SIP is the only protocol that helps companies migrate to a cloud-based VoIP system and extends the system to remote locations. Moreover, SIP also facilitates a variety of deployments so as to support all the enterprise communication activities and needs.

Changes in corporate communication

Corporate communication has undergone a sea change in the recent years and this has raised the expectations of users as well. Nowadays, everyone wants to remotely log in to the corporate server and keep an eye on their work. Thus, SIP trunking is the ideal choice for meeting such advanced communication demands as it not only supports mobility, but it also helps to integrate technologies that we frequently use for communicating on a real-time basis.

Rise of new communication technology

The demand for the SIP & SIP Trunking is going to rise because the space is fast being occupied by WebRTC (Web Real-Time Communication). There is still a little time for this new technology to be formally adopted by the corporate world, but with its rapid development, it is just a matter of a few years.
