How does Bluetooth work?
Many of you reading this may remember the bad old days of making any two gadgets talk to each other. Cell phones (not smartphones!) all had their own proprietary cables. Computers hadn’t yet embraced the Universal Serial Bus, so they had a mess of different connection standards. WiFi didn’t exist yet, although some phones had infrared connections.
These were slow, you had to line up the two transmitters perfectly and they only worked at a distance where the phones were practically touching! So thank goodness for Bluetooth! It’s a name you’ve heard of, but not one that explains much about what it actually is.
As you may have gathered from the opening paragraph, Bluetooth is a wireless digital communications technology. It allows two Bluetooth devices to connect to each other and exchange data over radio waves.
