Bluetooth was designed to allow low bandwidth wirelessconnections to become easy to use so even those whoare new to wireless can use them. Version 1.1 of Bluetooth describes a low power, short range wirelessnetworking technology that uses radio waves to senddata at rates up to 720 kilobits a second.
The specification for Bluetooth provides for differentclasses of radio that allow transmission ranges ofup to 100 meters by boosting the radio power. Thetechnology of Bluetooth isn't limited to line of sight transmission since it uses directional wavesthat are capable of transmitting through many obstructions.
Bluetooth is an industry standard communication ofwireless, meaning that it enables the connectionof other devices as well, such as cell phones,computers, digital cameras, and other types ofelectronic devices. The specification of Bluetoothdefines a radio system and a "stack" of protocol layers and profiles. The highest layer is theapplication layer, while the lowest layer is theradio.
The wireless technology of Bluetooth is positioned to revolutionize the personal connectivity market by providing freedom from inconvenient fixed type lines.
The specification for Bluetooth eliminates the need for cables by providing a small form factor, low cost wireless solution that will link computers, cell phones, and other electronics. Bluetooth also allows users to connect many ranges of devices quickly and easily and expands communications capabilities as well.
The size of the Bluetooth radio is amazing, as a Bluetooth radio can be built into one or two very small microchips then integrated into any electronic device where wireless operations would be an advantage.
Bluetooth also offers a robust link, which ensures that normal operating circumstances are not interrupted by interference from other signals that are operating in the same frequency band.
Also known for its world wide operation, Bluetooth radio operates in the 2.4 GHz frequency band, whichis license free and available to any type of radio system in the world. No matter where you are in the world, you count on Bluetooth to work.
Security is also important. Offering advanced security mechanisms, Bluetooth ensures a high level of security. Therefore, authentification will prevent unauthorized acess to important data and make it very difficult to listen in.
Bluetooth also boasts power optimization. The radio is power friendly and the software for Bluetoot his very configurable, limiting the power consumption of equipment. The radio itself only consumes a small amount of power from a cellular phone.

Key Learning Points Of Bluetooth
Bluetooth is easily the best in wireless handheld technology. When it comes to learning, Bluetoothcan get quite complicated. To help you, you'll findthe key learning points of Bluetooth below:
1. Bluetooth is an energy efficient, lowoverhead communication protocol that's ideal for interdevice communications.
2. Unlike infrared, Bluetooth doesn't requiread line of sight.
3. Depending on the implementation, Bluetooth can have a range of up to 100 meters.
4. The specification of Bluetooth consists ofa Foundation Profile Document and a Foundation Core Document.
5. The protocol stack for Bluetooth consists of core protocols, cable protocols, and even adapted protocols.
6. The transmitter operates around the 2.4GHz frequency band.
7. The data channel will change frequency, orhops, 1,600 times in a second, between the 79 allocated channels in the ISM band.
8. Bluetooth utilizes a spread spectrum frequency hopping RF characteristic to ensure that independant networking operates when the other devices are in range.
9. A piconet is formed when one or more devices open up a channel of communication.
10. A piconet can have a master and up to seven slaves.
11. Communication of the interdevice is based on the concepts of channels.
12. All Bluetooth devices are capable oftransmitting voice.
13. The channel has a total capacity of1 MB per second.
14. There are two types of channels with Bluetooth - SCO (Synchronous Connection Oriented) andACL (Asynchronous Connectionless).
15. The SCO channels are time oriented, andare therefore primarily used for transferring time critical data such as voice.
16. ACL channels are normally used for communicating data.
17. Data contained in a packet can be up to2,745 bits in length.
18. In a single piconet, there can be upto three SCO links containing 64,000 bits a second each.
19. To avoid collision and timing problems,SCO links are reserved slots that are set up by the master.
20. The masters can support up to three SCO links with either one, two, or three slaves.
21. The slots that aren't reserved for SCO links can be used as ACL links.
22. The LMP (Link Management Protocol)will handle link level security, error corrections,and the establishment of communications links.
23. The LMP packets will have priorityover user packets that originate and form theL2CAP layer.
24. The L2CAP layer will ensure an acceptable quality of service. 25. No more than one ACL link can existat the L2CAP layer.

Using Bluetooth and The Bluetooth Solution
The amazing technology of Bluetooth presents a greatway of exchanging data between two wireless devices.Unlike telephones, there are no wires or messy leads to worry about. You can enjoy wireless communications with short distances of up to thirtyfeet.
Bluetooth also offers interoperability, meaning thatyou can use your portable Bluetooth device to connectwith existing Bluetooth points. This way, you won'thave to carry a data lead or CDs of drivers aroundwith you everywhere you go. You can enjoy the bestof wireless without having to worry about installingyour software.
With today's Bluetooth, you can use your PDA and cellphone to surf the net or check emails as you travel.If you are in the business field, this can be verybeneficial, especially if you like to check youremail throughout the day. Bluetooth will enable youto check your email no matter where you are - whichis great news for those who like to travel.
Bluetooth will also enable to you to transfer filesas well, such as MP3 and photo to and from your mobiledevice. Bluetooth dominates the world of short rangewireless, enabling you to do more than you may have thought possible.
One of the best things to Bluetooth and somethingeveryone loves is the wireless headset. Bluetoothoffers wire free headsets for your cell phone orcomputer, which is great for those who like to walkaround or talk on the phone in the car, without having to worry about your hands getting in the way.
To make things even better, you can use a BluetoothGPS device for satellite navigation on your PDA, laptop, or mobile. If you travel - this can be really great to have.
The Bluetooth Solution
The technology of Bluetooth will take small areanetworking to the next level by removing the needfor user intervention and help keep transmissionpower very low to preserve battery power. Eachtransmission signal to and from your cellular phone will use just 1 mw of power, giving you plenty of space on your battery to talk.
Bluetooth is a networking standard that willwork on two levels: 1. It will provide agreement at thephysical level, as Bluetooth is a radio frequencystandard. 2. It will provide agreement at the levelof protocol, where products will have to agreeon when bits are sent, how many are sent, and howthe parties in conversation can be sure the messagerecieved is the same one that was sent.
The major draws to Bluetooth is the fact that it's wireless, inexpensive, and automatic. Thereare other ways to get around wires, includinginfrared. Infrared uses light waves of a lowerfrequency than the human eye can, and is normallyused in television remote controls.
The technology of Bluetooth is intended to getaround the problems that normally come withinfrared systems. The 1.0 older standard ofBluetooth has a max transfer speed of 1 MB asecond, while the 2.0 Bluetooth standard canmanage up to 3.0 MB a second. To make thingsbetter, 2.0 is compatible with 1.0 devices.
As a solution to wireless, Bluetooth will eliminate the need for messy cords, keeping everything nice and neat. It's perfect for thosewho like to talk on cell phones, as you nolonger need to hold the phone next to yourear - which is great for those who travel a lot.
