As you’re hunting around for wireless headsets to go with your unified communications implementation you’ll likely come across the DECT standard. Bluetooth and DECT technologies are widely used for wireless headsets.You may find yourself wondering just what DECT is and how it differs from Bluetooth.
This simple Article will, hopefully, put the matter to rest.
DECT stands for Digital Enhanced Cordless Telecommunications, operates in or near the 1.9 GHz frequency band, where it does not interfere with other wireless technologies including Wi-Fi and Bluetooth.
DECT vs. Bluetooth
People are concerned that others may be able to tap into their call via the wireless connection, but 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 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.
DECT uses 64 bit encryption, and Bluetooth has 128 bit encryption, so once the headsets are appropriately paired with their base stations the chances of someone effectively listening in on a call is virtually nil.
The Distance Dilemma
The biggest difference DECT holds is its far greater range, around 100 meters. Bluetooth range varies depending on what class is in effect. Class 1 goes up to about 30 meters, Class 2 about 10 meters and Class 3 is 1 meter.
If users need it only for desk or computer-based phones, as in a enterprise, a DECT headset makes sense.It also afford the ability for users to move about pretty much at will.
If the 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’re well within the 10-meter limit.
There are number of communication headset brands offering wireless headsets with DECT technology. For example IPN headsets from Nether lands, comes with key features like “400 meters of roaming range capability and highly secured & clear conversations, integrates your desk-phone & PC calls into one headset, three-party conferencing calls on one station and finally accessories for multiple wearing comfort”.
