Learn What is the difference between Bluetooth and WiFi For Beginner

Both Wi­Fi and Bluetooth are found in almost every laptop, tablet and smartphone. But they’re

Very different, and generally used for different things. They can be on and active at the same time,

Doing these different things, or you can use each one separately.

What is WiFi?

Wi­Fi, which originally meant “wireless fidelity,” is primarily about connecting one or many devices

With the Internet, or creating a local wireless network that can link multiple devices. It depends on a

Central bus 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. By far the most typical

Wi­Fi scenario for consumers is the wireless router installed by an Internet provider in a home. It

Sends out what might be thought of as invisible Internet “rays” around the house that can be

Tapped into by Some laptops, smartphones or tables within them.

What is the Bluetooth?

Bluetooth is a short­range wireless solution for pairing one device with another; Wi­Fi has greater

Range and works with multiple devices. Bluetooth is much shorter­range, usually around 30 feet in

My experience. It rarely involves getting onto the Internet, and doesn’t depend on any central

A Device like a router. It is almost always used to connect two devices together in some useful way. One example is that wireless speaker and smartphone my friend wanted to use. The phone

And speaker talks 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. That’s why it doesn’t matter

Whether there’s Wi­Fi in the room.

Difference between Bluetooth and WiFi?

Because 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. This usually involves typing a

The number generated by one into the other. WiFi has no such pairing requirement, though you’ll

Need a password to access a private Wi­Fi network. Wi­Fi can also act like Bluetooth, connecting

Two devices directly over a short range. A version called Wi­Fi Direct does this. It can transfer

Photos and files between nearby devices, just like Bluetooth.

1_range:

Bluetooth is normally used to provide ad­hoc (device­to­device) voice/data transfer between

Mobile devices within a short range, low bandwidth small data transfers (voice transfer between

Wireless headset and cell phone or data transfer between PDA and laptop), and some peripheral

Connections (keyboards, mice, printers). It is not intended to transfer large amounts of data (that

Require a high ­bandwith, high­speed connection) and usually has a normal maximum range of 20

Feet between the two objects and usually require a direct line of sight. The cost of Bluetooth

The devices still averages at 2x the cost of the equivalent WiFi devices. Bluetooth is found, primarily in

Cellular phones (including Smartphones), gaming consoles (like Playstation 3), and some of the

Higher end laptops.

Wi­Fi is mainly used to provide wireless networking and Internet connection between wireless

Devices with a larger coverage area (up to 250 feet for areas without interference) and high

Bandwidth data transfers (to share high­speed Internet connections or data and files between

Computers connected). Many new smartphones are now also using WiFi technology as a way to
Cut costs on data usage (primarily on the Internet, etc. for users when they are near hotspots. All
Laptops, netbooks, mid to high­end Apple products, some desktops, some TVs and Home Theatre

Receivers, most gaming consoles, and some personal audio devices (like iPods) all come WiFi-
Ready.

2­bandwidth:

Bluetooth and Wi­Fi are different from each other in many aspects. Wi­Fi has large bandwidth
Which results in large speed of transfer and it also requires more power and the hardware required is also expensive. While on the other hand, Bluetooth requires very less power and very cheap hardware for it. But the range of Bluetooth is not as large as Wireless LAN and Bandwidth is also not as large as WLAN.

3­freuency

The Frequency range used by both WLAN and Bluetooth is same but multiplexing techniques used are different. Bluetooth is often taken as Wireless USB while a WLAN is known as Wireless Ethernet. Though, Bluetooth has lower bandwidth than WLAN but its bandwidth is still larger than wires or conventional systems for which it was implemented. And the Bandwidth of Wi-Fi is obviously much larger than the conventional systems or LANs.
