Bluetooth works similarly to WiFi and cellular networking, but it's designed for different purposes. Even though Bluetooth can perform some of the same functions as WiFi, it's optimized to perform simpler tasks at a shorter range.
Usually, WiFi and cellular technology are used to make large networks or connect several devices to the Internet, while Bluetooth works on a smaller scale, like linking a headset to a mobile phone or speakers to a tablet. In this way, they are complementary rather than competing technologies. One of the advantages of Bluetooth is the ease of connecting devices.
If you want to connect two devices—like a mobile phone and headphones—the process is fairly simple. Keep in mind, though, that Bluetooth menus on many devices will be slightly different. Many simpler devices—like remote controls and headsets—have a specific way to put them in pairing mode. If the device doesn't have a menu or other obvious way to connect via Bluetooth, consult the device's manual. I am sure there are many other uses as well. If you know any other uses of Bluetooth, scroll down and let us all know in the comments.

If he is not writing about technology, you will find him spending quality time with his little family. I have a Bluetooth OBDII reader that plugs into my vehicle and I can read error codes and get all kinds of other information about my vehicle. I can also reset the idiot light after I have any problem fixed.
It ties directly to a free app on my Android phone. Of course you can push a WIFI signal through a cable network but you must first demodulate it from the high frequency…It is pointless as you can see..!!
In addition I would like to say that bluetooth communications are not so secure as you can think , they can be compromised very easily… so be careful when you are using this kind of connection transferring sensitive data.

This short-range frequency is commonly used by most appliances that need wireless connectivity, including Wi-Fi routers. What makes Bluetooth different is the use of a technique called frequency hopping. It's a bit technical, but there's a simple explanation. Bluetooth uses 79 bands of radio waves in the aforementioned 2. When you send data, Bluetooth first divides this data into smaller packets.
These packets are sent individually over those 79 bands, and Bluetooth is smart enough to change bands rapidly so that no one line gets clogged.
That's the main platform of the technology. With the smart "hopping" of data transfers, Bluetooth can simultaneously connect up to eight devices and allow them to talk to each other. This is a commonly asked question, especially since Bluetooth's competitor Wi-Fi is associated with internet connections.
The short answer is No! Bluetooth does not use any data. PAN does not require an internet connection or mobile service to transfer files or anything else. The difference between these was more necessary a few years ago, but it's not something you need to concern yourself with anymore.
Most devices bought in the five or so years come with Bluetooth 4. This process of breaking down data into smaller packets and sending them individually is also why Bluetooth is used mainly for small data transfers that don't need to happen quickly. If you need to transfer large amounts of data quickly, there are better wireless protocols than Bluetooth.
Specifically, Bluetooth 4. The distance between devices is about yards with Bluetooth 4. Technically, Wi-Fi and Bluetooth are both wireless standard protocols to let two devices connect without cables. But each technology's merits and application are different. Wi-Fi is a stronger and faster connection, which takes more battery. Bluetooth's focus is on battery efficiency.
A side effect of this is that Bluetooth actually maintains a more stable connection, since it interferes less with the same 2. While Bluetooth is generally the better technology to use for simple, low-power connections between two devices, you can also connect two devices with Wi-Fi Direct.
