Technolgies Used by Wireless Headsets

The world we live in gets smaller each day with expanding communication, and one of the biggest factors in this expanding communication is the use of wireless headsets. Wireless headsets are truly a great invention and in this day and age almost nobody can get by without the use of wireless headsets. You see them everywhere. Basically if you have some kind of communication device chances are you have wireless headsets. Another factor that has contributed to the widespread necessity of wireless headsets is the implementation of hands-free driving laws. These laws have made using wireless headsets necessary for even the people that barely use their phones, just so they can if they need too without ending up on the other side of the law.

One thing about wireless headsets that many people do not know is that not all wireless headsets use the same technologies. In the world of wireless headsets, there are actually 2 types of technologies that are used to allow wireless headsets to interact with their respective receivers.

Analog wireless headsets

These types of wireless headsets were the originals. Analog wireless headsets communicate using a shared frequency, usually 900mhz or 2.4ghz, between the wireless headsets and the receiver. One things cool feature about these wireless headsets is that if you are to use a different channel on the frequency, you can connect more wireless headsets to the same receiver. The problem with these wireless headsets, and the main reason they aren’t used much any more, is that they have no security. If you are using having a conversation with someone using analog wireless headsets, someone with a nearby radio could accidentally receive your signal.

DECT (Digital Enhanced Cordless Technology)

This technology used for wireless headsets was the main replacement for analog wireless headsets. Basically these types of wireless headsets fulfilled the need for more security as well as better call quality and range. The biggest difference between analog and DECT systems is that analog wireless headsets connect to a common frequency whereas DECT wireless headsets only connect when they are paired with the receiver. Another difference and the reason DECT wireless headsets are more secure is that DECT wireless headsets use a technique called channel hopping. Channel hopping means that the wireless headsets will change the channel they are using at random intervals making it impossible to predict which channel the wireless headsets will be using.

Bluetooth

Bluetooth is the newest technology used for wireless headsets and they were created to fulfill a need as well; the need for cheap wireless headsets. If comparing the three technologies used for wireless headsets, Bluetooth and DECT would be the most similar. Both types of these wireless headsets pair in the same fashion, and both channel hop for security. The main differences between Bluetooth wireless headsets and DECT is that Bluetooth has a range of about 30 feet, while DECT wireless headsets can range up to 300 feet. Another difference between Bluetooth and DECT is the call quality, which with DECT headsets is far superior, comparing to that of a landline, where Bluetooth wireless headsets have quality that is less then analog.

For the most part, in the communication world today, you will usually only find Bluetooth and DECT headsets because of the advancements that these technologies have made, but, in some areas, analog is still king.
