Bluetooth is a short-range wireless connection technology.
No matter where, you do not have to lay a special cable between electronic devices, through the Bluetooth can form a one-point-to-multipoint connection, any Bluetooth transceiver within the network can interoperate with the signal. For example, with a Bluetooth mouse, Bluetooth keyboard, Bluetooth headset, you do not have to plug in the cable on the computer, eliminating the need for a variety of lines wrapped around the trouble.
Bluetooth can also help you complete the transfer of files within different platforms, for example, it can help you send files from your computer to the top of your cell phone, but also connected to a Bluetooth-enabled printer to print out the required documents.
Currently, more than 2,000 organizations support and have adopted Bluetooth technology. This fact shows that Bluetooth is fast becoming one of the widely accepted low-cost wireless technologies for personal area networks. Bluetooth technology makes it easy for broadband access devices, telephones, PCs, information appliances, and other devices to transmit signals to each other over short distances.?
Extended Information
List of Bluetooth applications:
1. Wireless control and communication between cell phones and hands-free headsets. This was one of the early popular applications.
2, wireless control and communication between a mobile phone and a Bluetooth-compatible car stereo system.
3, Wireless control and communication between iOS or Android equipped tablets and devices such as speakers.
4, wireless Bluetooth headset and walkie-talkie. The headset is sometimes referred to simply as "a Bluetooth".
5, wireless audio streaming to the headset, no communication function.
6. Wireless networking between PCs with low bandwidth requirements in a limited space.
7, the wireless connection between the computer and the input and output devices, common mouse, keyboard, printer.
8, Transferring files, detailed address book information, calendar scheduling, memos, etc. between devices that can exchange objects.
9, replacing earlier wired RS-232 serial communications on test equipment, GPS receivers, medical equipment, bar code scanners, traffic control equipment.
10, for the previous frequent use of infrared control.
11, low bandwidth applications that do not require higher USB bandwidth and require wireless connectivity.
12, from the use of Bluetooth advertising version to send small advertisements to other Bluetooth devices that can be found.
13, A wireless bridge between two industrial Ethernet (e.g., PROFINET) networks
14, The controllers for three seventh- and eighth-generation game consoles, Nintendo's Wii and Sony's PlayStation 3, respectively, each employ Bluetooth
15, Dial-up Internet access on a PC or PDA can be achieved using a data-exchange-capable cell phone as a wireless modem.
16, Health sensor data is transmitted over short distances from a medical device to a cell phone, set-top box or specific telehealth device.
17, Cordless phones are allowed to ring or answer calls instead of nearby cellular phones.
18. Real Time Location Systems (RTLS) can be used to track and confirm the location of objects in real time through "nodes", "tags" affixed to or embedded in objects, and "read-write" devices that receive and process wireless signals from these tags. The location is confirmed through "nodes," "tags" affixed or embedded in the object, and "readers" that receive and process wireless signals from those tags.
19. A personal security application on a smartphone that prevents objects from being lost or stolen. Bluetooth identification (e.g., a tag) on the protected object to maintain continuous communication with the phone. If the connection is interrupted (e.g. the tag goes out of range of the phone) then an alarm goes off. This can also be used as a man overboard alert.
20. Wireless transmission of audio.
