For example, you can connect two computers on the same local area network to transfer files between them wirelessly. Bluetooth is used to transfer data between your electronic devices over short distances. For example, you can use Bluetooth to connect your computer to a wireless keyboard or pair your phone with a Bluetooth speaker.
Like WiFi, Bluetooth also uses radio signals to send data between devices. In fact, Bluetooth uses some of the same frequencies as WiFi, which can cause interference with WiFi devices. However, unlike WiFi, Bluetooth does not require you to use a password to connect to a device.
Typically, you will need to pair your Bluetooth devices by pressing and holding a button on one device. Then you will select that device from another device.
Bluetooth is also slower than WiFi, and it has a shorter range usually up to 30 feet. Originally invented as a way to connect devices without using cables, Bluetooth is now supported in almost every wireless device you can find. These days, Bluetooth is in most computers, laptops, cell phones, tablets, keyboards, mice, headphones, console gaming devices, smartwatches, fitness trackers, hearing aids, and many other peripheral devices. If you see the Bluetooth symbol on a device, it means you can connect it to other Bluetooth-enabled devices wirelessly.
For example, you can use Bluetooth to connect your phone to wireless headphones and wireless speakers. You can also use Bluetooth to connect a wireless keyboard and mouse to your desktop, laptop, or tablet.
You can use Bluetooth to transfer data from one device to another without a WiFi connection.

Miller addresses the relationship between two methods for wireless communication: IEEE Learn about how these technologies are optimized for specific usage cases and why the two technologies are complementary, rather than competitive with one another.
Like this article? Like for example a high speed digital trunking network, for digital and sharp voice services applications at a affordable cost.
Not just to mention the OpenBTS project. Thank you John, useful as usual. Thanks for the very through article. Thank you Mauricio for the feedback! You are exactly right about why I left off SigFox. I had it on the list but then decided it would be better to leave it off.
It is very informative article, with comparison of wireless technology in short, which I have not came across before. Thanks for the comment. Interesting article and good comparison of the current wireless technologies.
Voice communication is in most cases not possible. You can then decide if you want a second processor for low power data communication if your data rate does allow it. There is no such thing as low power voice communication as far as I know.
I hope this will be introduced in the near future. Thank you for sharing this by commenting. Very good point. I rarely deal with voice applications over cellular, most just data, so that was my focus. Notify of. Newest Oldest Most Voted. Inline Feedbacks. Vineeth Mathew.
