DECT and Bluetooth are the two main wireless protocols used to connect headsets to other communications devices.

DECT is a wireless standard used to connect cordless audio accessories with a desk phone or softphone via a base station or a dongle.

So how exactly do these two technologies compare to each other?

DECT vs. Bluetooth: Comparison

Connectivity

A Bluetooth headset can have up to 8 other devices on its pairing list and be connected to 2 of those at the same time. The only requirement is that all devices in question are Bluetooth-enabled. This makes Bluetooth headsets more versatile for everyday use.

DECT headsets are intended to be paired with a single dedicated base station or a dongle. In turn, these connect to devices like desk phones, softphones, etc. and can carry any number of simultaneous connections at a time, depending on the product in question. Because of their reliance on the base station / dongle, DECT headsets are primarily used in traditional office and contact center settings.

Range

Standard DECT headsets have an indoor operating range of around 55 meters but can reach up to 180 meters with direct line of sight. This range can be extended further---theoretically without limitations---by using wireless routers spaced around the office.

The operating range of Bluetooth varies by device class and usage. Generally speaking, Bluetooth devices fall into the following three classes:

Class 1: Has a range of up to 100 meters

Class 2: These have a range of about 10 meters

Class 3: Range of 1 meter . Not used in headsets.

Class 2 devices are by far the most widespread. Most smartphones and Bluetooth headsets fall into this category.

Other Considerations

The dedicated telecommunications nature of DECT devices guarantees a more stable, clear call quality. Bluetooth devices can experience external interference, which could lead to occasional drops in call quality.

At the same time, Bluetooth is far more versatile when it comes to usage scenarios. Most Bluetooth devices can easily pair with each other. DECT relies on its base station and is limited to the deskphones or softphones with which it is paired.

Both wireless standards offer a secure, reliable way to connect telecommunications devices with each other. What you choose depends on you. Office or Contact Center worker: DECT.Hybrid or On-the-go Worker: Bluetooth.
