Besides connecting to the internet, you can also use WiFi to connect your devices within the same network. 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. As with all technology, Bluetooth did not remain static. The original form that some may call Bluetooth classic was reinvented more than once, most significantly in when it released version 4. The way BLE achieves a reduction in energy consumption is by staying in sleep mode until roused by activation through a connection.
The amount of energy saved as a result is quite impressive. As a result, all it takes to power basic BLE devices is a very small battery. A small 1, mAh coin cell battery can keep it going for up to two years, according to the blog. Given the impressive efficiency of BLE, one may think that it has completely supplanted the classic version.
But that is not the case, because the low energy version is not up to providing uninterrupted transmission that we have come to expect from our computer and smartphone tasks.
Like Bluetooth, Wi-Fi works off a radio frequency. In that network, Wi-Fi-enabled devices can connect so long as they are within range of the signal, which can extend to feet. Product manufacturers must complete Wi-Fi interoperability certification testing, as conducted by the Wi-Fi Alliance , in order to label devices as Wi-Fi devices.
First introduced in , Wi-Fi can work off 2. Typical Wi-Fi is used to allow access to the internet, so that a home, office, library, or hotel can have several devices pick up on the service without being plugged in. That form of connection is what makes the Internet of Things IoT possible, to have smart homes, devices, and appliances that can be accessed over the internet from anywhere. The downside is that it also can create a point of vulnerability that leads to the phenomenon of being hacked though an aquarium and the like.
Despite its association with getting connected online, Wi-Fi can now be used to connect devices directly to each through what is known as Wi-Fi Direct , which is more comparable to Bluetooth in functionality than standard Wi-Fi.
Wi-Fi Direct devices can connect anywhere, anytime—even when there is no access to a Wi-Fi network nearby. Wi-Fi Direct devices emit a signal to other devices in the area, letting them know a connection can be made.
Users can view available devices and request a connection or may receive an invitation to connect to another device. Wi-Fi Direct connections are faster than Wi-Fi connections made over the internet because they only entail a single-hop rather than two—one to the router and another to the intended device. That is a consideration when it comes to limited battery power on mobile devices.
