The Advantages And Disadvantages for Using Bluetooth

Bluetooth has a lot to offer with an increasingly difficult market place. Bluetooth helps to bring
with it the promise of freedom from the cables and simplicity in networking that has yet to be matched by LAN (Local Area Network).

In the key marketplace, of wireless and handheld devices, the closest competitor to Bluetooth is
infrared. Infrared holds many key features, although the line of sight it provides doesn't go through walls or through obstacles like that of the Bluetooth technology.

Unlike infrared, Bluetooth isn't a line of sight and it provides ranges of up to 100 meters. Bluetooth is also low power and low processing with an overhead protocol. What this means, is that it's ideal for integration into small battery powered devices. To put it short, the applications with Bluetooth are virtually endless.

Have to know more about bluetooth now ? I will give you a 10 benefits of using and choosing bluetooth for application.
Below, are 10 benefits and reasons to use Bluetooth technology.

1. Wireless
As you probably already know, there are many benefits and advantages to using wireless devices. Along with improving safety as a result of eliminating wires you don't need, wireless also offers you plenty of other advantages. When traveling with your laptop or other wireless devices, you'll no longer have to worry about bringing connection cables.

2. Bluetooth is actually inexpensive
The technology of Bluetooth is cheap for companies to implement, which results in lower costs for the company. These savings are then passed from the company on to you.

3. Bluetooth is automatic
Bluetooth doesn't have you set up a connection or push any buttons. When two or more devices enter a range of up to 30 feet of each other, they will automatically begin to communicate without you having to do anything.

4. Standardized protocol
Bluetooth is standardized wireless, meaning that a high level of compatibility among devices is
guaranteed. Bluetooth will connect devices to each other, even if they aren't the same model.

5. Low interference
Bluetooth devices almost always avoid interference from other wireless devices. Bluetooth uses a technique known as frequency hopping, and also low power wireless signals.

6. Low energy consumption
As a result of Bluetooth using low power signals, the technology requires very little energy and will use less battery or electrical power as a result. This is an excellent benefit for mobile devices,
as Bluetooth won't drain the battery.

7. Sharing voice and data
The standard for Bluetooth will allow compatible devices to share data and voice communications. This is great for mobile phones and headsets, as Bluetooth simplifies driving and talking on your cell phone.

8. Instant PAN (Personal Area Network)
You can connect up to seven Bluetooth devices to each other within a range of up to 30 feet, forming a piconet or PAN. For a single room, you can
also set up multiple piconets.

9. Upgradeable
Upgradeable is the standard for Bluetooth. There are newer versions of Bluetooth in the works,
which offer many new advantages and backward compatible with older versions.

10. The technology stays
Bluetooth technology is a world wide, universal wireless standard. With it being as popular as
it is, you can count on it being around for years to come. As more and more devices start to use
Bluetooth technology, more manufacturers will be eager to make their products compatible. A chain reaction will occur, making Bluetooth the standard for cutting edge wireless.

Every technology have some problem right ? A bugs and some reason for not choosing that. here are some information about why blue tooth is bad.

Disadvantages
Bluetooth has several positive features and one would be extremely hard pressed to find downsides when given the current competition. The only real downsides are the data rate and security. Infrared can have data rates of up to 4 MBps, which provides very fast rates for data transfer, while Bluetooth only offers 1 MBps.

For this very reason, infrared has yet to be dispensed with completely and is considered by
many to be the complimentary technology to that of Bluetooth. Infrared has inherent security due to its line of sight. The greater range and radio frequency (RF) of Bluetooth make it much more open to interception and attack. For this reason, security is a very key aspect to the Bluetooth specification.

Although there are very few disadvantages, Bluetooth still remains the best for short range wireless technology. Those who have tried it love it, and they know for a fact that Bluetooth will be around for years to come.

Why Always Bluetooth Application

Knowing about bluetooth. And need some info about what and why must bluetooth in some default. Theres some viewable and reason why bluetooth is the reason of some. And why bluetooth have more famous than infra red. In condition of this case. Now i will show you why this is was here. The paradigmatic. With new electrical devices being produced every day, the problem of connecting things is becoming more and more complex in nature. The system that comprises computers and other electronics makes use of varieties
of wires, cables, etc.

These parts will communicate through light beams, lasers, radio signals, and infrared. The problem however, is the devices and technology is often the connection between each component. Therefore, most electronic systems aren't used to their full extent
due to the problems and imperfections. To help simplify things, a solution was created -
the solution of Bluetooth. Bluetooth is wireless and automatic, offering users a variety of features that have simplified the art of connection. Bluetooth has revolutionized the standard methods of connecting things to enabling almost anything to be connected to a single system.

Aside from Bluetooth, there are other ways of connecting wireless devices. One example of such is the IR or infrared. Infrared allows low frequency light waves to transmit signals to another component. This technology is easy to create and the cost of putting the IR device into a system is rather low. Infrared technology is a one to one process. Due to the limitation, you may only send signals from one device to another, similar to a television set and remote control. You can only transmit signals between the two although not with a seperate system.

Aside from the fact that these two natures of infrared are obstacles to acquiring results, these
same qualities have worked in advantage to the connection. Infrared devices need to be lined up
directly, meaning too little interference can occur between the transmitters and receivers.

The technology behind Bluetooth works by transmitting signals through low frequency radio signals. The path of communication is working on 2.45 GHz, which is the same frequency band used in ISM devices.
Are you hvave to know the bluetooth more in the up case that i have show you ? Know i will show you why bluetooth has born and have been default application in cellular phones

For Bluetooth, there are literally hundreds of different applications and devices available for you
to use or purchase. As you may already know, Bluetooth is the most popular wireless technology
in the world. It's very reliable, very dependable, and very hard to crack into.

There are many other applications for Bluetooth in development now, many of which plan to take the wireless age to the next level. Video game systems are using Bluetooth technology as well, for their wireless controllers. This is great news for gaming fans, as Bluetooth offers the best in wireless data transmission.

If your curious about applications for Bluetooth that are still in development, you can search on
the internet. You can find all sorts of information, especially when it comes to Bluetooth. As the
future arrives, you can expect Bluetooth to bring bigger and better things.

The Function of Bluetooth Works

The Previos post we have learn some introduction of bluetooth. And now, i will show you about the function of the bluetooth. Anyway bluetooth devices will normally operate at 2.4 GHZ in the license free, globally available ISM radio band. The advantage to this band includes worldwide availability and compatibility. A disadvantage to this however, is that the devices must share this
band with other RF emitters. This includes automobile security systems, other wireless devices, and other noise sources, such as microwaves.

To overcome this challenge, Bluetooth employs a fast frequency hopping scheme and therefore uses shorter packets than other standards within the ISM band. This scheme helps to make Bluetooth communication more robust and more secure.

Frequency hopping
Frequency hopping is basically jumping from frequency to frequency within the ISM radio band. After a bluetooth device sends or receives a packet, it and the device (or devices) it's communicating with hop to another frequency before the next packet is sent. This scheme offers three advantages :
1. Allows Bluetooth devices to use the entirety of the available ISM band, while never transmitting from a fixed frequency for more than a short period of time. This helps insure that Bluetooth conforms to the ISM restrictions on the transmission quantity per frequency.
2. Ensures that any interference won't last long. Any packet that doesn't arrive safely to its destination can be resent to the next frequency.
3. Provides a base level of security as it's very hard for an eavesdropping device to predict which frequency the Bluetooth devices will use next.

The connected devices however, must agree upon the frequency they will use next. The specification in Bluetooth ensures this in two ways. First, it defines a master and slave type relationship between bluetooth devices. Next, it specifies an algorithm that uses device specific information when calculating the frequency hop sequences.

A Bluetooth device that operates in master mode can communicate with up to seven devices that are set in slave mode. To each of the slaves, the master Bluetooth device will send its own unique address and the value of its own internal clock. The information sent is then used to calculate the frequency hop sequences.

Because the master device and each of the slave devices use the same algorithm with the same initial input, the connected devices will always arrive together at the next frequency that they have agreed upon.

As a replacement for cable technology, it's no wonder that Bluetooth devices are usually battery
powered, such as wireless mice and battery powered cell phones. To conserve the power, most devices operate in low power. This helps to give Bluetooth devices a range of around 5 - 10 meters.This range is far enough for wireless communication but close enough to avoid drawing too much power from the power source of the device.

Knowing What is Bluetooth Are For

Now i want to provide you for some articles that writen about Bluetooth. Bluetooth was designed to allow low bandwidth wireless connections to become easy to use so even those who are new to wireless can use them. Version 1.1 of Bluetooth describes a low power, short range wireless networking technology that uses radio waves to send
data at rates up to 720 kilobits a second. The specification for Bluetooth provides for different
classes of radio that allow transmission ranges of up to 100 meters by boosting the radio power. The technology of Bluetooth isn't limited to line of sight transmission since it uses directional waves that are capable of transmitting through many obstructions.

Bluetooth is an industry standard communication of wireless, meaning that it enables the connection of other devices as well, such as cell phones, computers, digital cameras, and other types of electronic devices. The specification of Bluetooth defines a radio system and a "stack" of protocol layers and profiles. The highest layer is the application layer, while the lowest layer is the radio.

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 worldwide operation, Bluetooth radio operates in the 2.4 GHz frequency band, which is 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 Bluetooth is very configurable, limiting the power consumption of equipment. The radio itself only consumes a small amount of power from a cellular phone.
