These days, all communication technology faces the issue of privacy and identity theft, with Bluetooth technology being no exception.

Almost everyone knows that email services and networks require security.

What users of Bluetooth technology need to realize is that there should be Bluetooth security.

The good news for Bluetooth users is that the security scares, like most scares, are normally over dramatized and blown entirely out of proportion.

The truth being told, these issues are easy to manage, with various measures already in place to provide Bluetooth technology.

It’s true that there have been some Bluetooth phones that have been hacked into. Most devices that are hacked into are normally those that don’t have any type of security at all.

According to Bluetooth specialists, in order to hack into a Bluetooth device, the hacker must:

1. Force two paired devices to break their connection.

2. Steal the packets that are used to resend the pin.

3. Decode the pin. Of course; the hacker must also be within range of the device and using very expensive developer type equipment. Most specialists recommend that you have a longer pin, with 8 digits being recommended.

Constantly evolving, the Bluetooth technology started off as a basic wireless connection standard but has since then been adapted and proven with many different uses and functions.

A good example is Bluetooth technology for cell phones. It enables mobile users to connect to their hands free headset without using wires.

Bluetooth technology will also allow mobile phone users to connect with their hands free kit as well.

Another handy use of Bluetooth technology is file sharing. It allows the sharing of files between two cell phones, between a cell phone and computer, which makes the sharing of files a snap. If you have a cell phone and computer, you can easily transfer data between the two.

Say for example you wanted to put an MP3 on your phone from your computer you could do it easily with Bluetooth technology. All you would need is a Bluetooth adapter for your computer. It doesn’t stop with the swapping of files either, as you can use your computer and phone to synchronize phone books, send SMS messages, and much more.

In the United States, Bluetooth gets absolutely no respect. It is however, becoming more and more common in notebooks, PDAs, and especially cell phones.

Bluetooth will provide wireless users a way to transmit small amounts of data over short distances.

Now, Bluetooth is facing stiff competition from new wireless technology. Referred to as UWB or Ultra Wideband, it promises data transfer of up to 480 MB a second - while most current Bluetooth devices transfer data up to 721 KB a second.

For the time being, Bluetooth devices are surely cropping up. Below, we will look at some of the accessories offered with Bluetooth technology.

Talking to the dashboard

When pairing it with a cell phone, the CCM Blue Warrior car kit becomes a great speaker Bluetooth phones that plugs into the power adapter of your vehicle. The noise cancelling microphone will reduce background noise efficiently, with the large buttons making adjusting the speaker volume a snap. Although the Blue Warrior is far from sexy or sleek, it’s very practical.

Bluetooth is a specification for the use of low power radio communications to wireless phones, computers, and other network wireless devices over short distances.

The name Bluetooth is actually borrowed from Harald Bluetooth, a Denmark king more than 1,000 years ago.

The technology of Bluetooth was primarily designed to support simple wireless networking of devices and peripherals, which includes cell phones, PDAs, and wireless headsets.

The wireless signals that are transmitted by Bluetooth cover short distances of up to 30 feet, generally communicating less than 1 MPps (Mega Byte per second).

The networks of Bluetooth feature dynamic topology called PAN or a piconet. The piconets contain a minimum of two and a maximum of eight peer devices. The devices will communicate using protocols thatis part of the specification.

Even though the Bluetooth standard will utilize the same 2.4 GHz range as 802.11b and 802.11g, the technology isn’t suitable for a Wi-Fi replacement. When compared to Wi-Fi, Bluetooth is much slower, limited in range, and actually supports fewer devices.

For short range devices, Bluetooth is rapidly becoming the best. The technology is more popular with cell phones, as Bluetooth headsets are the way to go these days. To use Bluetooth headsets, your cell phone will need to have it enabled, or an Infrared device somewhere on the phone.

Creating good wireless Bluetooth headsets is actually difficult to do.

The regular wired Bluetooth headsets are easy to design - with ranging styles.

Bluetooth headsets can never be as small or as light as wired Bluetooth headsets, simply because it needs to include the battery and extra functions. This extra size will impact how the Bluetooth headsets mount on or around your ears.

Comfort: There seems to be two main styles of Bluetooth headsets. Some are held into place with a loop around the ear. These styles are normally more comfortable, although they may be less secure. The others are held in place by being jammed into your ear - and usually prove to be less comfortable.

Factors to consider for Bluetooth headsets

Cost: The cost is an obvious issue, something that you really need to think about.

Ergonomics:

1. Check to see if the device is easy to quickly and conveniently put on your ear then take it off again.

2. Are the control buttons on the Bluetooth headsets easy to use?

3. The Bluetooth headsets should be comfortable to wear for long phone calls.

4. Can you use it with a pair of glasses?

The networking standards of Bluetooth will transmit data via low power radio frequency. Bluetooth communicates on a 2.45 GHz frequency.

This very band of frequency has been set aside by international agreement for the use of industrial and medical devices.

Many Bluetooth devices that you already know and use, take advantage of this frequency band. Garage door openers, baby monitors and the next generation of mobile phones all use this frequency within the ISM band.

Ensuring that Bluetooth devices and the other devices don’t interfere with each other is a crucial part of the design process.

One of the ways Bluetooth devices will avoid interfering with other electronic devices is by sending out weak signals of around 1 mw. In comparison, even the most powerful of cell phones can transmit a signal of 3 watts.

The low power signals will limit the range of a Bluetooth device to around 32 feet, which cut the chances of interference between your computer and other electronic devices. Even though it has low power, Bluetooth devices don’t require a line of sight between the communicating devices. The walls in your home won’t stop the signal, making it great for rooms throughout the house.

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.

Because it meets the basic needs of connectivity in close range, Bluetooth devices has a very bright future ahead.

Bluetooth is actually the result of initiatives from nine leading communications and computer industry giants, including 3-COM, Sony, Lucent, IBM, Nokia, Microsoft, etc.

Since the forming of the original group, more than 1,800 manufacturers around the world have joined the initiative.

According to reports, the Bluetooth technology is expected to be built into more than 100 million devices, with over 670 million enabled Bluetooth devices.

Resulting from the amazing success of WAP (Wireless Application Protocol), the adoption of smart phones and hand held devices, Bluetooth devices can easily have an amazing impact on your day to day life.

Bluetooth is one of the key technologies that can help to make the mobile information society happen, by blurring the possibilities between home, the office, and the world outside.

The seamless integration and connectivity that Bluetooth promises will make it possible to explore a wide range of interactive and highly transparent personalized services which were actually quite difficult to dream of simply because of the complexity involved with making such Bluetooth devices communicate with each other.

The technology of Bluetooth wireless is a short range communications method intended to replace the cables that connect portable or fixed devices while maintaining the highest levels of security.

The key features offered by Bluetooth device include low power and low cost. The specification in Bluetooth defines a uniform structure for a wide range of devices to communicate and connect with one another.

The technology behind Bluetooth device has achieved global satisfaction such as enabled devices, almost everywhere in the world. Bluetooth device will connect and communicate without wires through short range and networks known as piconets.

Each Bluetooth device will simultaneously communicate with up to seven other devices within a single piconet, meaning that each device can also belong to several piconets simultaneously.

The piconets are dynamically established as Bluetooth device enters and leaves the proximity of radio.

A fundamental to Bluetooth device strength is the ability to handle both data and voice transmissions simultaneously with the help of piconets. The piconets will enable users to enjoy varieties of innovative solutions such as hands free talking, printing and fax capabilities, and other applications.
