what is bluetooth?

Answer 1

Bluetooth is an industrial specification for wireless personal area networks (PANs), also known as IEEE 802.15.1. Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers and digital cameras via a secure, globally unlicensed short range radio frequency.

The name Bluetooth was born from the 10th century king of Denmark, King Harald Bluetooth, who engaged in diplomacy which led warring parties to negotiate with each other. The inventors of the Bluetooth technology thought this a fitting name for their technology, which allowed different devices to talk to each other.[1]. The name of the king in Danish was Harald Blåtand and the Bluetooth logo is based on the H and B runes.

Introduction

A typical Bluetooth mobile phone headsetBluetooth is a radio standard and communications protocol primarily designed for low power consumption, with a short range (power class dependent: 1 meter, 10 meters, 100 meters) based around low-cost transceiver microchips in each device.

Bluetooth lets these devices communicate with each other when they are in range. The devices use a radio communications system, so they do not have to be in line of sight of each other, and can even be in other rooms, so long as the received power is high enough. As a result of different antenna designs, transmission path attenuations, and other variables, observed ranges are variable; however, transmission power levels must fall into one of three classes:

Class Maximum Permitted Power
(mW) Maximum Permitted Power
(dBm) Range
(approximate)
Class 1 100 mW 20 dBm ~100 meters
Class 2 2.5 mW 4 dBm ~10 meters
Class 3 1 mW 0 dBm ~1 meter

Bluetooth applications
Bluetooth was designed to fill a range of use cases or applications. To improve interoperability, Bluetooth Profiles were written to make sure that the application level works the same way across different manufacturers' products. Listed below is a range of use cases for different Bluetooth profiles.

Wireless control of and communication between a cell phone and a hands free headset or car kit. This is the most popular use.
Wireless networking between PCs in a confined space and where little bandwidth is required.
Wireless communications with PC input devices such as mouses and keyboards.
Wireless communications to PC output devices such as printers
Transfer of files between devices via OBEX.
Transfer of contact details, calendar appointments, and reminders between devices via OBEX.
Replacement of traditional wired serial communications in test equipment, GPS receivers and medical equipment.
For remote controls where infrared was traditionally used.
Sending small advertisements from Bluetooth enabled advertising hoardings to other, discoverable, Bluetooth devices.
Wireless control of a games console, Nintendo's Wii and Sony's PlayStation 3 will both use Bluetooth technology for their wireless controllers.
Sending commands and software to the upcoming LEGO Mindstorms NXT instead of infra red

Answer 2

BlueTooth is a specification for the use of low-power radio communications to wirelessly link phones, computers and other network devices over short distances. The name "Bluetooth" is borrowed from Harald Bluetooth, a king in Denmark more than 1,000 years ago.
Bluetooth technology was designed primarily to support simple wireless networking of personal consumer devices and peripherals, including cell phones, PDAs, and wireless headsets. Wireless signals transmitted with Bluetooth cover short distances, typically up to 30 feet (10 meters). Bluetooth devices generally communicate at less than 1 Mbps.

Answer 5

Bluetooth is a short range communication protocol for devices like computers and cell phones. Your cell phone and your digital camera are really just computers with special functions, and a very compact size that limits what they can do.

A communitcation protocol is how one computer talks with another. They have to speak the same language, and the same dialect. Bluetooth is just one way of doing that.

Answer 6

its a wireless form of technology.. it is applied in many different forms of tech, such as bluetooth wireless headsets, speaker, microphones, bluetooth usb
