There are many benefits of using wireless devices. The basic plus to going wireless is enjoying the freedom to work or communicated without being tied down. You can travel freely and stay connected, without the hassle of connection cables. There is a safety factor to consider as well. Bluetooth technology eliminates the risk of getting tangled with wires if, for example, you're wrestling with a wired headset while trying to drive a car.

2. Instant Gratification
Using Bluetooth devices allows you the freedom to communicate without setting up connections or pushing buttons. When two or more Bluetooth devices enter a range of 30 feet or less, they will instantly begin to communicate with each other. There's nothing more that you need to do.

3. Budget Friendly
The benefits of Bluetooth also extend to your pocketbook. Bluetooth technology is inexpensive for companies to implement. Lower costs lead to lower corporate overhead, and the savings may well be passed on to customers like you.

4. Sets the Standard
Bluetooth is standardized wireless. This means that the technology is guaranteed to meet a high level of compatibility with other wireless devices. Bluetooth technology allows many different devices to connect and communicate, even if they are different models.

5. Less Interference
Bluetooth devices are almost always able to avoid interference from other wireless devices. The Bluetooth uses a technology known as frequency hopping, as well as low power wireless signals.

6. Conserves Energy
Bluetooth uses low power signals, so the technology requires very little energy. One of the most practical benefits of Bluetooth you'll find is in using fewer batteries or less electrical power. Bluetooth won't drain the batteries on mobile devices.

7. Shared Data and Voices
The standard for Bluetooth technology allows compatible devices to share data and voice communications. Of all the benefits of Bluetooth this is most important to drivers who need to talk hands-free on their cellphones.

8. Instant Personal Area Network
You can form your own PAN (personal area network) by connecting up to seven Bluetooth devices within a range of up to thirty feet. Multiples PANS, or piconets, can be set up within a single room

9. Upgrade
Technology is constantly being upgraded, and Bluetooth is ready to comply with whatever changes may come along. Newer versions of Bluetooth are now being released, offering even more advantages. Many have backward compatibility with older Bluetooth versions.

10. Technology For Keeps
Bluetooth technology is used and available worldwide. It's a universal standard that will be around for many years to come. As more and more devices implement Bluetooth technology, more manufacturers will find it necessary to make their products compatible. The "supply and demand" chain reaction has already set Bluetooth as a standard in cutting-edge wireless.

There are more benefits to Bluetooth; just ask anyone who uses this wireless wonder. Find out more about Bluetooth, and then decide if the benefits of Bluetooth can help make your life a little easier.

How Bluetooth Features Will Change What You Do Today

Bluetooth is the name for an emerging technology that uses short-range radio links instead of cables to connect portable electronic devices. This allows a wide range of devices to communicate with one another without actually being physically connected to one another.

Some of the most notable features of Bluetooth technology are the facts that it is relatively inexpensive (this is first and foremost for many potential consumers); it is not extremely fragile, it is very user friendly, and has low power consumption. Bluetooth can be used to create wireless Personal Access Networks (PANs) while offering fast and reliable transmission of both voice and data. Bluetooth offers wireless access to the Internet (for home access as well as laptops, PDAs, and other hand held devices), cell phone services, and local access networks.

A complete Bluetooth system requires an RF portion in order to send or receive data; a module for processing, a memory module, and an interface to the electronic device it is to communicate with (such as a phone, Palm, or camera).

The lower-layer protocols can typically be found within the baseband module and the host processor must support the protocols of the upper-layer. Simply put, the RF-baseband solution supplies the means necessary in order to communicate with the host. This additionally requires an interface by which they can connect as well as the 'upper-layer' protocols in order to actually apply the applications the product is designed to support.

The higher upper layers of Bluetooth technology are referred to as Bluetooth Profiles. These profiles are literally a set of protocols that are optimized in order to complete specific tasks or applications. If you wish to share files between two linked devices they must be compatible devices that have similar applications across the spectrum of devices.

The Bluetooth stack has the following components:

1) RF portion. This is necessary for reception and transmission.

2) Baseband portion.

3) Link Control Unit4) Link Manager. This supports lower layer protocols.

5) Interface. This allows a connection to the host device.

6) Host processor. This will support upper layer protocols.

7) L2Cap. This also supports upper layer protocols.

The Radio Frequency (RF) supplies the Digital Signal Processing (DSP) element to the system while the baseband microcontroller processes the signals. The link controller supports the link manager and controls the baseboard functions by sending and receiving data, identifying the device sending data, performing authentication, and determining the frame to which the transmission should be sent. The link controller also directs the way devices communicate with each other as well as enabling the power saving sleep mode when not being directly used.

The link manager is responsible for setup, authentication, the configuration of links, and other lower layer protocols. The baseband and link manager work together in order to establish connections for the network.

The Host Controller Interface (HCI) allows the communication of lower layer protocols to the host (which contains a processor) device. The L2Cap supports upper layer protocols and enables communication with the lower layers. The higher-upper layer protocols are often very specific tasks and applications that require integration with the lower layer applications. The ability of all these components to work together and communicate adequately is very important to Bluetooth technology.

Core Protocols in Bluetooth technology:

1) Baseband. This layer combined with the link control layer enables an RF link to form while offering two distinct physical links with corresponding baseband packets. These links are Synchronous Connection-Oriented and Asynchronous Connectionless. Synchronous Connection-Oriented connections can contain either audio or a combination of data and audio while Asynchronous Connectionless packets can only be used for the purpose of transmitting data.

2) Link Manager Protocol. This is responsible for establishing links between Bluetooth devices including but not limited to security functions such as authentication and encryption keys as well as the negotiation duty cycles for the Bluetooth device and the device on the receiving end.

3) Logical Link Control and Adaptation Protocol. This adapts the upper layer protocols over the baseband.

4) Service Discovery Protocol. This allows device information, services and characteristics of services to be queried. Once queried, a connection can be made between two or more Bluetooth devices.

Telephony and Cable Replacement Protocols:

1) Telephony Control Protocol. This is a bit oriented protocol that defines the control signal for the call and establishes speech and data cells between the devices.

2) RFCOMM. This is a serial line emulation protocol. It is based on European Telecommunications Standardization Institute's specifications and emulates control over Bluetooth baseband. This provides not only transport capabilities but also allows for upper level services that use serial lines as transport mechanisms.

Adopted Protocols:

1) PPP: PPP is the point-to-point protocol. PPP Networking is the act of taking IP packets from the PPP layer and putting them on the Local Access Network.

2) TCP/UDP/IP: TCP/IP/PPP this is used for all Internet bridge purposes. It is also available as transport for the WAP.

3) OBEX Protocol. This is a session protocol that is designed to exchange data simply and automatically.

Advantages:Bluetooth technology makes the use of peer-to-peer connectivity simpler by enabling all manner of devices to communicate freely and automatically. Bluetooth also allows for fast, secure voice and data transmissions. While the range for connectivity is only about 30 feet, line of sight is not necessary for the signals to be received and transmitted.

Bluetooth is also capable of functioning in noisy radio environments while ensuring audible voice transmissions even in less than ideal situations. It can correct data through use of error correction methods while providing a high transmission rate. You also have the ability to use encryption in order to provide added layers of security.

Bluetooth may also be used to create ad hoc networking among personal devices in order to quickly exchange information.

Bluetooth Connects Wireless Networking

Bluetooth is not the first wireless technology. The reliable and cheap infrared wireless technology was invented in 1998. However, on the downside, two devices using infrared must be within 'line-of-sight', that is, you have to aim it at the receiving device, also infrared is strictly a one-to-one relationship and doesn't allow connection with multiple devices simultaneously.

WiFi (Wireless Fidelity) is a close cousin of the Bluetooth; they both use the same wireless technology to communicate. That's where the similarities end. WiFi was designed to provide wireless data connectivity while Bluetooth was designed to provide wireless device connectivity to networking and internet.

Bluetooth uses a tiny microchip, which functions as a radio transmitter and receiver. Due to the size of the microchip, the Bluetooth device will only work with other devices up to 10 meters away. It is possible, however, to boost the range to 100 meters but that would also increase the power consumption.

Though Bluetooth represents futuristic wireless technology, the name 'Bluetooth' is actually 10 centuries old. Named after a Scandinavian King, Harald Bluetooth, who managed to unite several unruly kingdoms, Bluetooth refers to the taming of myriad unruly competing standards by defining one worldwide specification. Bluetooth was founded by Ericsson, IBM, Intel, Nokia and Toshiba, the group that dubbed itself the Bluetooth SIG (Special Interest Group). Now, there are over 2,000 companies providing Bluetooth solutions worldwide.

When shopping around for a Bluetooth-enabled device, just be on the lookout for the official Bluetooth logo, which indicates that the device complies with Bluetooth standards.

Bluetooth devices can be connected to either many-to-one networking or one-to-one networking. An example of the former is a computer using a Bluetooth mouse and keyboard at the same time. An example of the latter is a mobile phone connected to a Bluetooth headset.

Today, it is all about being wireless and Bluetooth allows users to be free of cables and wires. When you travel, you don't have to worry about keeping track of a bagful of cables and you can design your office without worrying about the length of cables and hiding them.

The great thing about Bluetooth is that it is so simple that a non-techie can set it up. Bluetooth doesn't require any special configuration. All you have to do is turn on the Bluetooth and the devices will find one another and connect automatically.

There are hundreds of devices available today that use Bluetooth as a means of wireless connection to networking. However, is Bluetooth right for you? It all boils down to personal preference. As usual, technology and convenience come at a price, so a Bluetooth-enabled device can be more expensive than a conventional wired contraption. If you want to get rid of the wires and are willing to pay for it, Bluetooth-enabled devices gives you that choice.

If you want to send files to your PC and do the sync without messy cables, look out for the Bluetooth feature in your PDA. If you want your cell phone to be able to talk wirelessly to your headset or send files to and from your PDA or PC, you need one with Bluetooth capabilities.
