Wi-Fi bluetooth

To put it simply, first of all the difference is in the way of application. If Wi-Fi is used to connect a large number of devices into one local network for further access to the Internet. Whereas with Bluetooth the task of communication between two devices directly as in wireless: headphones, mice, keyboards, remote controls, etc.

Wi-Fi + Bluetooth adapter for computer and not only: a brief review

Hello, dear readers of our quiet and friendly portal WiFiGid.ru! In this article, we are going to talk about Bluetooth + Wi-Fi adapters on the market today. It's not so easy to find such things nowadays, but many people want to get everything in one set so that it doesn't take up space in your computer or laptop. All that I could find on the subject, I publish here.

Did you find another interesting model? Leave it in the comments, it will definitely help other readers in their search. Let's help each other, and thank you very much from us!

Complex or separate?

In fact, perhaps you have a problem of misunderstanding? Bluetooth is a separate technology. It's convenient to use at home to connect, for example, headphones to a phone or to pair a smartphone with a fitness bracelet. That is, it is used for short-range communication when connecting devices.

Wi-Fi is mainly used at home as an alternative to a classic local network over the wire. That is, it is connecting all the devices through a router with each other, as well as giving them all access to the Internet via a wireless network.

The problem is that there are so many separate adapters for both. Here are some of our current picks:

That is, there are much more of these adapters separately, and the likelihood of possible problems is reduced – many have noted that the combined Chinese products occasionally have problems with driver compatibility. Do you need it? My choice was unambiguous – to go the way of separation. It's easier, and in case of failure it is not difficult to replace. Moreover, the prices for these products with their long life cycle are not so high.

What is the difference between Wi-Fi and Bluetooth: the main differences and which technology is better?

Hello all! In today's article we will dissect the question – what is the difference between Bluetooth and Wi-Fi. Oddly enough, but these technologies are often confused with each other. And this is understandable, since Wi-Fi and Bluetooth use in their armament transfer data through the air wirelessly by means of banal radio waves.

It is true that the two technologies have a lot in common, but first things first. In this article I will try to describe and explain this issue as simply and understandable as possible, but if you have any questions, feel free to write about them in the comments.

Similarities

As I have already mentioned, the main similarity is the transmission of information through radio waves. Both Wi-Fi and Bluetooth use the 2.402 GHz to 2.48 GHz frequency range. In both cases, radio waves are used to transmit information from one device to another and back again. That is probably where the most important similarity ends.

Now we will look at the main difference. First of all, let's look at the word Wi-Fi itself, or in full "Wireless Fidelity" – which in translation means "Wireless Network". About wireless, we've already understood, but here's what exactly the word network means.

Many people confuse the word "Wi-Fi" with "Internet", but in fact they are different things, although they can be related to each other. To make a wireless or WiFi network work – you need a special device: a router or a router. The router starts to build a wireless network around itself, to which other devices can connect: phone, tablet, laptop, TV, etc.

It is the router that connects all of these devices intelligently. If you connect a cable from your ISP to the router and configure it, then all the devices connected to the router will have Internet. But as I said, there may be no internet, but there is no problem with WiFi. For example, if you are disconnected from the Internet because you have not paid, you can still connect to the wireless network, but of course the Internet will not be there. Now I hope you understand that wi-fi and the Internet are only indirectly connected.

Bluetooth, on the other hand, is used for a direct connection. For example, when you connect Bluetooth headphones to the phone, the information goes directly from the smartphone to the second device – without the participation of the router.

Changing the channel width

See, the 2.4 GHz frequency in the wi-fi world has two channel widths:

The problem with the wider channel is that by doing so, it starts to overlap even more with other channels, which leads to even more interference. Therefore, in the same place in the Web-interface of the router change the setting and set the channel width of 20 MHz. Apply, save and check the connection.

Manipulations with the phone

Try to turn off the phone and wait for about 2-3 minutes. The thing is that in a smartphone, the Wi-Fi module and Bluetooth are next to each other. If it overheats, you may see a problem with both connections. If this does not help, you can try to reconnect the headphones. In this case, the AFH mode should start, which will find a free frequency. Go to "Bluetooth", highlight your headphones, click on the gear and then click on the "Remove" button. After that, reconnect them.

You can try updating the operating system on your phone (if an update has already come out). Perhaps this will solve some of the nuances of connecting and working with the wireless module. If this does not help, then go to "Settings" – "System" – "Advanced" – "Reset settings".

Look, there are several options here. First, try resetting the Wi-Fi, mobile Internet, and Bluetooth settings. You can try doing an app reset. A total reset of the entire phone should only be done last – read the other chapters in this article first.

Bluetooth and Wi-Fi: which is better for connecting to the IoT

When it comes to which wireless technology is better, it depends on what you plan to achieve. The advent of Bluetooth technology makes short-range wireless communication possible, but its complex protocol and high cost make it unsuitable for widespread use in home networks. Real-world use cases such as smart homes, building management systems, Industry 4.0, and remote asset monitoring based on BLE and Bluetooth mesh specifications show that Bluetooth appears to be the preferred technology for low-bandwidth Internet of Things communications.

Energy efficiency, resource weight, Cost, and other form factor limitations have always been major concerns when deploying the Internet of Things using Wi-Fi… The high mobility of Wi-Fi allows users to access the Internet at any time. so it is more suitable for office and home environments. however, WiFi uses radio frequency technology to send and receive data over the air. and data signals are transmitted through radio waves, which are sensitive to external interference. In the stiff competition of the Internet of Things, WiFi is far behind.

In short, compared to low-power and low-bandwidth communication standards, Bluetooth radio is better. Although Wi-Fi is an excellent and very reliable protocol, its range of use is very limited. The Wi-Fi router is used for surfing the Internet, so you probably have to put one in.

Can I use Bluetooth without WiFi?

It is possible, for sure. Bluetooth allows you to transfer data between devices without going online, but many devices require a WiFi connection to work properly, so not all Bluetooth devices can work without WiFi. For example, you need to send files from your computer to a printer using WiFi. However, if you have a Bluetooth printer, a WiFi connection is not required.

Can you run Bluetooth and WiFi at the same time?
Yes. Bluetooth and WiFi work separately without interference, so you can use both functions at the same time. However, because Bluetooth and Wi-Fi signals primarily use the 2.4 GHz frequency band, it may be that they cannot work at the same time.

Which consumes more data: Bluetooth or Wi-Fi?
Neither Bluetooth nor WiFi requires cellular data. Bluetooth devices establish connections without surfing the Internet, so you don't have to worry about paying for excess data. Wi-Fi allows smart devices to access the Internet without using cellular data… Note that when your smartphone is not connected to WiFi, many network service providers automatically switch it to cellular data, which can cause excessive data charges.
