  • 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.

  • Its got a short range, devices disconnect randomly

  • and it uses up battery life.

  • Even thought it's been around for 20 years, why does Bluetooth still suck?

  • 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 '90's

  • 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 Blatand.

  • 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.

  • Because of this, the ISM is brimming with devices.

  • And they all interfere with your Bluetooth devices.

  • Any device running on Bluetooth,

  • falls into one of three classes.

  • Class one, for long range, these need a power supply,

  • and are mainly used for industrial purposes.

  • They have a range of nearly 330 feet.

  • Class two, they have a range of about 30 feet.

  • This is what most cellphones and speakers use.

  • Class three devices have a range of less than 30 feet.

  • Class two and three devices

  • generally use low power Bluetooth.

  • But even low power can use

  • a precious battery life on your phone.

  • And if you have a class two speaker,

  • 20 feet away from your phone,

  • it still may not work great.

  • Especially if there's any interference

  • coming from other devices.

  • Bluetooth also transfers data much slower than WiFi does.

  • While devices connected via the new WiFi Direct standard

  • will be able to transfer data at 250 megabits per second,

  • Bluetooth 4.0 can only get up

  • to 25 megabits per second max.

  • There's no superfix for these issues coming anytime soon.

  • But if you want to improve the connection

  • between two devices, there are a few things you can do.

  • Keep the devices as close together as possible.

  • Keep your devices updated.

  • Reset your connections daily.

  • Or even use a device that can amplify a Bluetooth signal.

  • While there's no sure fix yet,

  • some companies are taking matters into their own hands,

  • developing technology that works a lot like Bluetooth.

  • Apple's W1 chip enables its AirPods

  • to switch to whatever device you're using,

  • rather than having to unpair and re-pair

  • the devices each time.

  • Will we start seeing other companies

  • take wireless communication into their hands?

  • We'll just have to wait and see.

Has this ever happened to you?
