Wi-Fi has no such pairing requirement, though you’ll need a password to access a private Wi-Fi network. This usually involves typing a number generated by one into the other.

Wifi vs bluetooth Bluetooth#

If you’ve purchased a brand-new car in the past few years, you likely had the option of getting Bluetooth installed in your vehicle.īecause Bluetooth is a direct device-to-device technology and used for so many different things, it typically requires that you first “pair” the two devices being linked. Other common examples of Bluetooth scenarios are wireless headsets for making phone calls, or wireless keyboards and mice for computers and tablets. That’s why it doesn’t matter whether there’s Wi-Fi in the room. The phone and speaker talk directly to each other over Bluetooth, which beams the music from the phone to the speaker without the need for any third device or wide network. One example is that wireless speaker and smartphone my friend wanted to use. It is almost always used to connect two devices together in some useful way. It rarely involves getting onto the Internet, and doesn’t depend on any central device like a router. It sends out what might be thought of as invisible Internet “rays” around the house that can be tapped into by any laptops, smartphones or tablets within their range to get online.īluetooth is much shorter-range, usually around 30 feet in my experience. It depends on a central base station (or multiple stations) that sends out a network signal strong enough and wide enough to cover, say, an office or home, a coffee shop or even an airport.īy far the most typical Wi-Fi scenario for consumers is the wireless router installed by an Internet provider in a home.

Wi-Fi, which originally meant “wireless fidelity,” is primarily about connecting one or many devices to the Internet, or creating a local wireless network that can link multiple devices. They can be on and active at the same time, doing these different things, or you can use each one separately. But they’re very different, and generally used for different things. So here goes.īoth Wi-Fi and Bluetooth are found in almost every laptop, tablet and smartphone. But she still wondered if this was a reliable solution, because she didn’t know if the location of the event had a Wi-Fi network.Īs I tried to explain that Wi-Fi was irrelevant in this case, it occurred to me that a lot of people may be too embarrassed to ask what the difference is between the two widely used forms of wireless data transmission. I suggested a Bluetooth speaker, and showed her how it worked. Today, co-executive editor Walt Mossberg offers some advice based on a question he recently received.Ī few weeks ago, a very smart friend asked me how she might play music from her iPhone through an external speaker to entertain about 40 people at an event, without using any cables.
