With different electrical devices produced everyday, the problem of connecting things is becoming more and more complex. The system that comprises the computers and other electronic devices makes use of varieties of connecting wires, cables and the likes. These parts communicate through light beams, lasers, radio signals and infrared. However, the problem with this devices and technologies is often the connection between each component. Thus, most systems are not used to their full extent due to complexities.

To simplify things, a solution was created to streamline the process of connections- bluetooth.

Bluetooth is wireless and automatic and offers users with varieties of excellent features that has recreated the art of connection. It has revolutionized the standard method of connecting things that virtually anything can be connected on a single system. From computers to mobile phones and from keyboards to headphones by means of wireless, automatic and inexpensive connection.

Other than the bluetooth technology, there are other ways of connecting things. Take for example the infrared or IR. It allows low frequency light waves which the eye can no longer interpret to transmit signals to another component. The technology is easy to create and cost of incorporating the IR device into a system is in barest minimum. Yet it has limited operations that seldom obstructs the process of connection.

Infrared technology is one to one process. Due to this limitation, you may only send signals from one component to another, like the case of the television set and the remote control. The same is true between laptops and desktops. You may only transmit signals between the two but not with another separate system, say a PDA through simultaneous actions.

It also works only on the line of sight principle wherein one has to point the infrared device directly to the host system to achieve a desirable result.

In spite of the fact that these two natures of infrared technology are obstacles to acquiring results, these same qualities have worked in advantage to connection. Because infrared devices need to be lined up directly on opposing locations, too little interference occurs between transmitters and receivers. The one to one principle on the other hand is designed to transmit signals only to the original recipient. Given that there are varieties of infrared recipients in a location, the intended recipient alone will receive the signal coming from a transmitter.

However, technology was not contented with what infrared offers. They resolved these limitations through creating the bluetooth solution.

Bluetooth technology works by transmitting signals via low frequency radio signals. The path of communication is approximately working on 2.45 gigahertz. The same frequency band is utilized in ISM devices.

The design of the technology was such that it has created a new system that does not interfere with the other devices that make use of the same frequency band (e.g. ISM). One way of doing this is the programming of the bluetooth technology to only transmit signals that has 1 milliwatt or less. Beyond this, other systems may be affected. By comparison, cell phones and other mobile devices send signals at a rate of 3 milliwatts and more.

The standard range of the bluetooth is around ten meters. This lessens the possibility that interference between device may occur. With this low transmission, it is still possible for the user to transmit bluetooth signals between obstructing walls.

Bluetooth in many ways have contributed much in connecting individual systems without being bothered by the bulk of the cables and wires.

Top 4 Cell Phone Accessories You Need    by Steve Smith

Cell phones are such an integral part of our lives today that they we take them almost for granted. With so much multi-tasking and constant activity in our lives, we rely on them every day, and it's only when they become cumbersome or don't work for us that we realize how much we've come to count on them. The right accessories can improve the functionality and convenience of your cell phone as well as making it the envy of all your friends. These Cheap Cell Phone Accessories are absolute musts for today's best-dressed cell phones.

1. Anything Bluetooth. Bluetooth is simply a term for a low frequency radio wave signal frequency that is used to make any type of electronic equipment - in this case your cell phone - wireless. No more using those awkward wired headphones that you have to plug into your cell phone! Bluetooth earpieces are small, sleek and have enough range for you to walk about your desk or step away from your parked car while chatting away. You can also get Bluetooth car kits for hands free dialing. These allow you to talk all you want while driving with voice activation and dialing. Typical Bluetooth systems give you up to eight hours of talk time and 150 hours of stand-by.

2. Antenna Booster. You would think cell phones would have clear reception and great coverage just about everywhere these days. You'd be wrong. Getting an antenna booster is a simple solution that's inexpensive, easy to install and will widen your coverage area instantly. There's nothing more annoying than a dropped call or talking to someone who's cutting in or out. Weird problems like buildings that block cell phone reception are solved with a good antenna booster as well.

3. Amplifier Antenna. For cell phones that are the life line of road warriors, an amplifier antenna installed on the car is a must. These antennas are more powerful than the antenna boosters installed in the actual cell phones and are mounted on the rear windshield of the car. They give users great coverage in those areas known as "dead zones" between cell towers and in valleys or mountain areas.

4. Mobile phone charger. Yes, this sounds vaguely old-fashioned, but we still believe this is an essential accessory for anyone who travels a lot and talks a lot. After all, why run down your cell phone's battery when you're driving if you can be using a charger and prolonging the battery life for when you get out of your vehicle? The simplest solutions are usually the most elegant, and today's chargers for cell phones are light years beyond those old versions with the big coils and bulky plugs for the cigarette lighter that you could brain someone with. Check out the newer ones that feature slimmer, shorter cords and dashboard mount, drop-in holders for your cell phone.

Almost a quarter of people in the United States today use cell phones as their primary personal telephone. A few added accessories like the ones mentioned above can make them even more reliable and versatile. When you go shopping for your next phone purchase, be sure to look at a few good extras as well as the best Cellular Phone Accessories .
