What is the difference between Bluetooth® and WiFi®?
Bluetooth® and WiFi® are wireless technologies that use network wool networks (RF), but are used for fundamentally different purposes. The main purpose of Bluetooth® is to temporarily connect the individual's personal device at short distances, while the purpose of WiFi® is to connect multiple computers together to longer distances.
Although Bluetooth® and WiFi® create networks, Bluetooth® creates a network of personal areas (PAN) by generating low -frequency radio waves that can connect all interoperative devices. You may think about it as a "cloak" surrounding an individual user. For example, the Bluetooth® headset allows the Hands-Free mobile phone to be used for driving or work. Other types of personal devices can exchange files, synchronize data and even share Internet access via an Internet laptop, mobile phone, personal digital assistant (PDA) or iPod®.
Bluetooth® network can also be used to send files from NOTEBOK on the desktop or from a laptop to the printer. If the machine does not come with the built -in Bluetooth® ability, adapters are available. Most adapters use the universal serial bus port (USB), but other types of adapters are also available.
WiFi® also uses waves of radio frequencies (RF), but its protocols are designed to connect multiple computers. In the case of the company, WiFi® allows many computers to communicate with each other without tieing the cable between them, saving considerable money and time in the installation process. Computers working over WiFi® LAN can share databases, files, programs and sources, including printers, scanners and fax machines. Computers can also share Internet access, although this is not a LAN request.
home network WiFi® IS almost always set up to share access to Internet between all computer computers while this may or may not be configured for sharing withOUBORS AND SOURCES. Between Bluetooth® and WiFi® Bluetooth® is much easier to replace files between computers at home and even for sending files to a nearby printer. When establishing a Bluetooth® network, virtually no settings are connected, while LAN requires a certain configuration and know-how to allow files and resources to be shared.
Because Bluetooth® works with equipment operated, most often used to broadcast RF networks and generate a weak signal that does not apply over 30 feet (~ 10 meters) or so. Class 1 Bluetooth® can achieve 10x, aimed at connecting home -powered homes. WiFi® also comes in various flavors and architectures, currently meets or exceeds 300 feet (~ 100 m).
Bluetooth ® and WiFi® each adheres to specific protocols and standards that make it easier for manufacturers to design and introduce Bluetooth® and WiFi® products that will be interoperable with other brands and products that support the same withTandards. For example, since winter 2008, the current Bluetooth® 2.0 standard and the latest WiFi® standard is 802.11 n , faster than the previous standard, 802.11 g . When buying devices capable of network, make sure they support the desired standard and version.
The other way Bluetooth® and WiFi® differ is that WiFi® is supported by modems and routers, while Bluetooth® can support a number of almost endless products. Personal equipment and home entertainment products are developing forever, which makes interoperability a highly required function. Perhaps the largest common common value between Bluetooth® and WiFi® is that both technologies are incredibly useful and widespread; In Homes, businesses, government and virtually all aspects of life.
