Idea
of Bluetooth
Communication between different devices without wires
Communication technology (Bluetooth) wireless is a global specification for connecting all portable devices with each other, such as computer and mobile phone, Pocket PC, and audio and digital cameras.So that these devices can exchange data and transfer files between the Internet wirelessly.Was developed Bluetooth wireless technology by a group of interested are called Blutooth Special Interest Group
There are lots of ways in which electronic devices can be linked with each other such as the computer is connected to a keyboard or mouse, printer or scanner through wire Plug Almalovh. You can also connect personal notepad to your computer for electronic exchange of information through a private wire. The TV set and a video and a satellite receiver are all connected with each other through private cable and are controlled by devices Alrmot control operating in the infrared range.
The mobile device Tel connects to its base through radio waves operate at a limited distance (50 meters). And a stereo related Balsmaat through wires connected.
The aforementioned services and many others exist in every home and called electronic devices. To this day correlate these devices through the connecting wires. The delivery of these devices often aesthetically annoying and confusing in practice. One may feel that it specialty electronic engineering study to enable himself to control these devices and make the most of them.
Clarify the problem of the connection between the devicesThe connect two electrons with each other needs to agree on many points, these points:(1) How many wires needed to connect two? In some cases the only two wires such as stereo Balsmaat delivery At other times it requires 8 or 25 wires wire Kalouselat used in the computer and its peripherals.
(2) What type of connection used between two devices to exchange information? Is it straight or in parallel? For example, the computer uses two methods to connect through vents installed in the motherboard it reaches the printer with the computer in parallel while the keyboard and modem Visla with computer respectively.
(3) What kind of data exchanged between devices? And how they translate into private signals responsive to appliances? This is what is known as the Protocol Protocol. This protocols are used by all manufacturers example, can be connected to a Sony video with a TV from JVC. And because of the protocols used to exchange information already unified.
These points used by the producers (manufacturers of electronic devices) made it difficult to control the amount of links used even though the use of colored wires for Excellence, including as it can not bind all electronic devices with each other, such as computer and its accessories and communications equipment and devices home entertainment each other because that requires the preparation of new protocols and add more wires.
The idea of wireless connectivity (Bluetooth)Bluetooth is a new technology able to deliver sophisticated electronic devices such as computer and mobile phone, keyboard and headphones from the exchange of data and information from wires or cables or user intervention.
Has joined more than 1,000 global companies to Special Interest Group Bluetooth Bluetooth Special Interest Group is known by its acronym SIG and This technology replaces the wire connection.
What is the difference between Bluetooth and wireless connectivity?There is no doubt that wireless users in many applications such as transportation through the use of light rays in the long infrared a ray light does not see eye known as the infrared because it has reportedly smaller than the frequency of red light and used infrared devices to control the TV (Alrmot Control) and known as the Infrared Data Association and abbreviated IrDA It is also used in many peripheral devices to a computer.
The many companies such as Siemens, Intel, Toshiba, Motorola and Ericsson to develop specifications installed in a small plate radio module snaps into computers and telephones and electronic entertainment devices to become the devices supporting Bluetooth technology, which will benefit from the advantages as follows:• devices without wires: This makes the transfer of equipment and arranged to travel or at home easy and without hassle.• inexpensive compared with the current equipment.• easy to operate: devices can communicate with each other without user intervention and all you have to do is press the play button and leave the rest of the Bluetooth device to Athawwar with interested party through module, such as the exchange of files of all kinds between electronic devices.
Operating means Bluetooth at 2.45 GHz frequency and frequency consistent with medical equipment and scientific instruments and industrial making the spread of easy use. For example, the door can be opened Rj through infrared issued a special device for this but using Bluetooth can open the garage using a mobile device.
What about interference that may occur as a result of the mutual interference between the signals?Likely that the reader wonders if the devices will exchange information and data radio signals operating at 2.45 GHz frequency. What about interference that may cause interference that may notice on the TV screen when they interfere with the radio signals!!The overlap problem was solved in a smart way that the Bluetooth signal is weak and an 1 Miliat if compared to the signals as a mobile device that up to 3 watts. This weakness in the signal makes the impact of Bluetooth signals within a radius of 10 meters and these signals can penetrate Jdraan rooms which makes control devices from one room to another without having to go directly to the devices to be run.
When presence of several electronic devices in the room could overlap because we mentioned that the impact of Bluetooth in the range of 10 meters, the largest of the area of the room but this possibility is unlikely because there are clear continuous range frequencies signal Bluetooth, and where that term allocated frequencies Bluetooth is between 2.40 to 2.48 GHz and is this scan rate of 1600 times per second. This is what makes the sending device uses a specific frequency, such as 2.41 GHz for the exchange of information with another device while the two in the same room use another frequency such as 2.44 GHz and are choosing these frequencies automatically and randomly, which prevents interference between devices, because there is no more than two they use the same frequency at the same time. And that happened, it would be for a fraction of a second.
KFH supports (Bluetooth)Suppose you got a modern house organs Bluetooth technology works like a TV receiver, DVD player and stereo audio devices, computer and mobile phone. Each device, which already uses Bluetooth. How will these devices?
When devices are equipped with Bluetooth technology, these devices can learn required of them without user intervention where they can communicate with each other defines whether it was required to transfer data such as e-mail data from a mobile device to the computer or control other devices such as stereo control device Balsmaat . Establish networking between small devices and accessories, known as network personal personal-area network and abbreviated PAN or the name Allbeckont piconet used every single network frequencies available in the range of 2.48 GHz.
Take, for example a mobile device and the base of the company is the manufacturer has placed two tranches Bluetooth in each, were all programming unit titled specific address is located in the long devoted to this type of device. When run rule it sends a radio signal to receivers of the same title and as a mobile phone with the same title is needed, it responds to the transmitted signal and the network is established (Bekont) between them. And then does not respond to these organs for any signals from neighboring devices because they are from outside that network.
As well as with computer and electronic entertainment devices work the same mechanism as establish networks connecting devices to each other according to the addresses that are designed by the manufacturers. And then these devices, which will continue to become part of the network and exchange information between them using available frequencies. Network devices does not interfere with neighboring network because each running a different frequency.Has been programmed this Bluetooth chip with all the information necessary to operate and work required of them without user intervention.
Why, this technology named Bluetooth?Return the label to the King of Denmark Harold Bluetooth Harald Bluetooth who united Denmark and of Norway and brought them in Christianity died in 986 in a battle with his son. This name was chosen for this technology to signify how important companies in Denmark and of Norway, Sweden and Finland to the telecommunications industry, although the label has nothing to do with the content of the technology ...
