Has this ever happened to you? You're not alone.
Apple, Google and other companies have gotten rid of the headphone jack from their phones. This is pushing people towards wireless headphones, which means they'll have to rely on that Bluetooth connection.
The Bluetooth is still so unreliable. It's got a short-range, devices disconnect randomly and it uses up battery life.
Even though it's been around for 20 years, Bluetooth is a wireless standard used all around the world.
Wireless printers, keyboards, game controllers, speakers and headphones all use it. It was created by a group of engineers in the mid-'90s as a secure way to exchange data between devices.
The Bluetooth name and logo come from 10th-century Viking king Harald Gormsson who, similar to Bluetooth's purpose, unified two separate entities, Denmark and Norway. King Harald's nickname was Blatand, which translates from Danish to Bluetooth.
The logo comes from the initials of King Harald Blatant. It is a combination of the runic letters H and B.
Bluetooth uses the 2.4 gigahertz frequency to communicate with other devices. This frequency and a few others are referred to as the ISM band, for Industrial, Scientific and Medical devices.
This is the spectrum that baby monitors and cordless phones all use. It's also the same frequency, fluorescent lights and microwaves omit.
These frequencies don't require devices to have an FCC license to operate on them. This makes the band attractive to manufacturers because they don't have to deal with the FCC.
