Q:

What are the advantages and disadvantages of Bluetooth?

A:

The main advantages of Bluetooth are that it’s compatible and wireless. The disadvantages include that Bluetooth devices tend to be more expensive and they tend to run out of power quickly.

Bluetooth devices have considerably more compatibility than devices that use jacks. This is because many electronic devices have proprietary device jacks, or the technology they use for jacks quickly becomes outdated. Bluetooth devices can connect to any phone, smartphone or any other gadget that’s compatible with Bluetooth. Another advantage is that Bluetooth allows a device to be completely free of wires. Not only does this tend to make operating the device less of a hassle, it also allows for more flexibility and range. This makes Bluetooth headsets ideal for exercising, for example.

A downside to Bluetooth has to do with the fact that they are wireless. This means that they have to operate on battery power. Since many Bluetooth devices are small and don’t connect over wires, battery power and life often become a problem. The Bluetooth setting on a user’s phone might also drain power faster from that device. Another downside is that Bluetooth devices are often more expensive than other kinds. This is due to the extra technology they need to run.

  • Q:

    How does Bluetooth work?

    A:

    Bluetooth works by transmitting data through radio waves that operate at a low power level and a specific frequency to create an uninterrupted connection between two devices. The frequency that Bluetooth operates falls between 2.402 and 2.480 gigahertz and has been reserved for industrial, scientific and medical device use internationally. To avoid causing interruptions with other devices operating in the same radio range, Bluetooth signals are emitted at one miliwatts.
