What’s the difference between Wi-Fi and Bluetooth? Here’s how they work

Smart technology, like smart phones or smart watches, are being used more and more in our daily lives. But what is the difference between Wi-Fi and Bluetooth? They are both wireless connection technologies that allow your smart devices to communicate with each other. Here’s how they work:

Wi-Fi is a “wireless local area network” (WLAN) that allows one or more computers to communicate with another computer over short distances. A WLAN uses radio waves to transfer data from one device to another. A device such as a laptop transmits a WLAN signal to another device such as a phone through an access point, also known as a hotspot. This hotspot can be a router or a cable modem connected to an internet service provider (ISP). Once you have established an internet connection, you can use Wi-Fi to download apps, stream videos, send emails, and do many other activities on your device.

Bluetooth is a wireless technology that allows devices to connect and share information without using cables. Bluetooth works by using short-range radio signals. Your phone transmits this radio signal with minimal power consumption over a distance of up to 10 meters. For example, you can connect your phone wirelessly with headphones or smart speakers using Bluetooth

Smart technology can be found all over our homes and offices in the form of smart lightbulbs, smart speakers, and smart doorbells (to name a few). There are so many different kinds of smart technology, but they do share one common trait: they all require a connection to your home internet in order to work.

The two most popular types of wireless technology used with smart devices are Wi-Fi and Bluetooth. While these two technologies may seem similar at first glance, they’re quite different when you look at them more closely.

Wi-Fi is a wireless local area network (WLAN) that uses high-frequency radio waves to provide internet access to devices such as computers, smartphones, tablets, and other smart tech. Bluetooth is a short-range wireless communication protocol that allows devices to communicate with each other without the need for an internet connection.

Smart technology is the wave of the future. It’s all about using automated devices to manage your home and life, with a smartphone as the central control point. Sometimes referred to as “the internet of things,” smart technology can do everything from control your lighting and temperature to lock your doors and monitor energy usage.

If you want to get started exploring smart technology, there are two important questions you’ll need answered: what is Wi-Fi and what is Bluetooth?

The biggest difference between the two wireless technologies has to do with how they communicate. Wi-Fi uses radio waves to connect devices to a wireless router. The router then connects them to the Internet or other devices.

Bluetooth, on the other hand, uses short-range radio waves that only cover about 30 feet (about 9 meters) or so. Bluetooth sends data at a slower rate than Wi-Fi, but it doesn’t need an internet connection.

The Internet of Things is the phrase we use to describe the way technology is becoming more and more a part of our everyday lives. It’s often used in reference to smart devices, which are objects that can be connected to the internet. We’ve seen this with smart home devices, like lighting and heating controls and speakers, and smartwatches. The rise of smart technology has led to a boom in Wi-Fi and Bluetooth connectivity.

Wi-Fi is typically used for connectivity over longer distances, when your device needs to connect to the internet, while Bluetooth is used for shorter distance connectivity between devices.


The majority of us will have used Bluetooth at some point in our lives. You might have used it when connecting your phone to a speaker or headphones, or connecting your phone to your car’s infotainment system so you can play music from it while you drive.

Bluetooth was invented by telecoms vendor Ericsson in 1994. It’s become commonplace on phones, tablets, laptops and other portable devices because it consumes very little power and is relatively inexpensive to implement. Because Bluetooth doesn’t use much power it’s ideal for wearable technology such as fitness trackers or smartwatches – they don

If you’re using any device that connects to the internet, chances are you’re using Wi-Fi. Your computer, smartphone and tablet all use Wi-Fi to connect to your home or office router. But what about Bluetooth? When do you use it? Is it even safe? If you’ve ever had questions like these, you’re not alone.

To answer these questions and more, we have a list of the differences between Wi-Fi and Bluetooth.

Let’s start with the basics. Wi-Fi is a high-frequency radio wave that transmits data over the air. It can be used on multiple devices at once, as long as they are connected to the internet and within range of your network’s signal.

Bluetooth is similar to Wi-Fi in that it uses radio waves to transmit data over short distances. However, Bluetooth can only be used on one device at a time and requires both devices to be compatible with each other (think: a phone and headphones).

We’ve all had the experience of walking into a coffee shop only to find that the Wi-Fi is down. Suddenly, we can’t check our work email or get any work done, and if you don’t have mobile data, you’re out of luck.

The same principle applies to Bluetooth. This wireless communication is used in everything from your favorite headphones to your car. But what makes these two technologies different, and which one do you need? Here are some important things to consider:

How They Work


Wi-Fi (also known as WiFi, WLAN) is a wireless local area network (WLAN) technology that uses radio waves for data transmission. Wi-Fi devices connect to the network through routers, and the router then connects to other networks and the internet. A computer or laptop with built-in Wi-Fi can be connected directly to a Wi-Fi network without using cables; this allows us to use the internet in any location where there is an available network.


Bluetooth is designed for short range wireless communication between devices at distances as close as 10 meters (33 feet). Bluetooth technology uses radio waves in the 2.4 GHz band in order to communicate between devices

The idea of connecting a computer to the internet without wires is appealing for many reasons. Many people today like to be able to access the internet from their phone or laptop wherever they are and whatever they are doing, and Wi-Fi has made this possible.

Some Wi-Fi standards, such as the 802.11n standard, can provide internet access to users over fairly long distances, up to 100 meters indoors and 300 meters outdoors (with the right equipment). This means that a single Wi-Fi router can provide internet access to an entire house, or even a garden.

Bluetooth is also used for short-range communication between devices. It allows two devices to communicate over a distance of up to 10m (33 feet) by using short length radio waves in the ISM band at 2.4 GHz. Bluetooth was originally developed as a wireless alternative to RS-232 data cables, which were widely used at the time in many types of computers and peripherals. It was subsequently adopted by mobile phones and other portable devices, with most modern mobile phones supporting both Wi-Fi and Bluetooth connectivity.
