Choosing A Bluetooth Headset

Creating a good wireless headset for Bluetooth is actually difficult to do. The regular wired headsets are easy to design - with ranging styles.

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

Comfort
There seems to be two main styles of headsets for Bluetooth. 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

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 headset easy to use?
3. The headset should be comfortable to wear for long phone calls.
4. Can you use it with a pair of glasses?
5. Check to see if you can wear it with either ear.
6. When you aren't wearing it, you'll need to se how you would carry it with you.
7. The weight is important as well, as you don't want something that has the risk of falling off.

Ease of use.
1. The commands and controls should be easy to remember.
2. The volume level should be easy to adjust.
3. The unit should turn on quickly.
4. The manual should be very well written and easy for you to understand.
5. There should be a support number for you to call if you should experience any types of problems.

Features
1. You'll need to know about the battery, the talk time, type, and how to tell when it is going dead or fully charged.
2. How many devices can the unit be paired with?
3. Compatability is also important, as well as the warranty period.
4. Check the sound quality for both sending and receiving audio.
5. What type of range does the headset offer you?

Other important capabilities include voice tags, last number redial, tranfer calls, 3 way calling, link to other phones, call reject, and mute. You'll also want to note if it looks attractive, and if it's too big or too small.

Bluetooth Wireless Networking

Bluetooth technology offers three different types of defined ranges, based on output ranges. Class 1 devices are the most powerful, as they can have up to 100 mW of power, with a regular antenna giving them a range of around 130 - 330 feet.

The class 2 devices are lower power, offering up to 2.5 mW of power. A regular antenna will give them a range of around 50 - 100 feet. Class 3 devices use even less power, up to 1 mW of power to be exact. With a regular antenna, they will have a range of around 16 - 33 feet.

Even though you may not realize it, Bluetooth wireless technology has never been intended for anything other than short distance types of communication. With Bluetooth wireless, the shortrange is actually a benefit.

For one, the short range will reduce the change of interference between your devices and those that belong to others who are nearby. Overall, this is a basic type of security, designed to protect you and your devices.

Secondly, the lower power used for short range means a longer battery life. Most Bluetooth devices will get their power from a battery, meaning that anything you can do to lengthen the battery life is very important.

The wireless networking offered by Bluetooth is actually among the best, even though it uses short range communication. Bluetooth is used with wireless controllers, the internet, and even wireless headsets.

For the best in short range technology, Bluetooth is extremely hard to beat. If you've never tried Bluetooth before, now is the time. It's the best with wireless networking, especially for those who enjoy hands free talking on their cell phone.

Bluetooth Security

These days, all communication technology faces the issue of privacy and identity theft, with Bluetooth being no exception. Almost everyone knows that email services and networks require security. What users of Bluetooth need to realize is that Bluetooth also requires security measures as well.

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 security for Bluetooth technology.

It's true that there has 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.

Fundamentals of security The "pairing process" is one of the most basic levels of security for Bluetooth devices. Pairing, is two or more Bluetooth devices that recognize each other by the profiles they share - in most cases they both must enter the same pin.

The core specifications for Bluetooth use an encryption algorithm, which is completely and entirely secure. Once the devices pair with each other, they too become entirely secure.

Until they have successfully paired, the Bluetooth devices won't communicate with each other. Due to this pairing process and the fact that it is short range - Bluetooth technology is considered to be secure.

As the news has indicated, experienced hackers have developed ways to get around this level of basic security. There are ways to get around this threat, as you can install software to prevent hackers from getting in.

With Bluetooth becoming more and more popular, it's really no wonder that security is always in question. As Bluetooth gets bigger and better, security will always be something that no one really takes lightly.

If you've been concerned about Bluetooth security in the past, rest assured that newer devices will offer bigger and better security. Preventing hackers from getting in is something every owner is concerned about - and the manufacturer's are very aware.

Introduction To 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.
