Bluetooth technology is a type of the wireless technology that eliminates the need for the number of inconvenient cables and devices that are used to connect the computers, mobile phones, digital cameras, handheld devices and new digital appliances. Bluetooth enables the users to connect to a wide variety of telecommunication and computing devices easily, without cables.

It makes rapid ad hoc connections, automatic unconscious connections between two or more digital devices.

Bluetooth provides the opportunity of using the mobile data in different applications. Bluetooth makes wireless communication between the two devices in a localized area of a room of office or home very easily. Bluetooth technology uses radio-based links and all the connections between the devices and invisible and instantaneous.

By Bluetooth technology your laptop can send print request to a printer in your next room. Bluetooth is actually a standard for wireless communication between the devices in a relatively small area and it is therefore works fine in the personal area network (PAN) using radio frequency.

Any two devices that follow the Bluetooth standard can communicate with each other. A number of the Bluetooth devices like digital camera, mobile phone and handheld pc can form a network. You can send emails to your mobile phones from your laptop without any physical connect between your laptop and your mobile phones.

Features of Bluetooth technology

•Bluetooth technology uses radio waves for communication in 2.4 GHz

•It supports multipoint communication not just point to point.

•Bluetooth works in a small area of 10-15 meters.

•Bluetooth offers speed of 1-2 Mbps.

•Bluetooth chipsets are less expensive though more expensive than IrDA.

How Bluetooth Technology Works

Bluetooth is a high speed wireless link technology that uses the radio waves. It is designed to connect the mobile phones, laptops, hand held devices and portable equipments with almost no work by the end users. Unlike infrared Bluetooth does not require line of sight between the connecting units. Bluetooth technology is a modified form of the current Wireless LAN technology and it’s more acceptable for its relative small size and low cost.

The current circuits are contained on a circuit board of 0.9 cm square and a much smaller single chip version is in development and soon it will be in use. The cost of the Bluetooth device is expected to fall rapidly. Bluetooth chip has to be equipped in many devices. In Bluetooth technology, small and inexpensive transceivers have been placed in the digital devices.

The radio waves operate at 2.45 Ghz band on the Bluetooth devices. Bluetooth supports the data speed up to 721 Kbps and 3 voice channels. The Bluetooth chip can either be built into the devices or it can be uses as an adapter. In computer it can be used with the USB port. Each Bluetooth device has a 48 bit address from the IEEE 802 standards and the Bluetooth connections can be either point to point or multipoint. Bluetooth range is 10 meter but it can be extended up to 100 meters by increasing the power.

Bluetooth devices are protected from the external interference because they change their frequency up to 1600 times in a second. Bluetooth radio technology provides the bridge between the existing data network. Bluetooth guarantees security at the bit level and the authentication is controlled by the end user by using 128 bit key. An important face of the Bluetooth technology is that it instantly forms a network when two or more devices come closer in the range of each other.

Bluetooth Technology Benefits

Bluetooth technology is a convenient choice of communication in a wire free, short range environment. Bluetooth is a globally available standard for connecting the devices like mobile phones, digital cameras, laptops, MP3 Players, cars, stereo headsets etc. Bluetooth enable devices do not need to install any drivers. The key benefits of the Bluetooth wireless technology are its built-in-security, low cost, easy of use, robustness, and ad hoc networking capabilities.

The Bluetooth wireless technology is available globally. Many manufactures from the different companies are busy to implement the technology in their products. Bluetooth technology operates in the 2.4 Ghz, one of the unlicensed, industrial and scientific radio band. Bluetooth technology is a free of charge service but your mobile phones set should support the GSM and CDMA technology.

Today mobile phones have built in capabilities and Bluetooth functionalities in them. Bluetooth technology is available in the different range of the devices like mobile phones, automobiles, medical devices, industries and enterprises etc. Due to the key features of the Bluetooth technology like low power consumption, low cost and wireless features make it more popular. Bluetooth technology does not require any fixed infrastructure and it is very simple to install and setup.

We live in a great day and age. Information is readily available at all times. We have cable TV, radio, computer applications and the Internet. We’re experiencing information overload most of the time.

Unfortunately, some people are not able to take advantage of the benefits of the Information age. The reasons may range from lack of access to an inability to use information literacy tools. And some people are not interested in the benefits of technology and information.

However, there is only one real barrier to taking advantage of the information age. The irony is most people impose the barrier on themselves. Yes, it is true.

There is one fundamental skill needed to take advantage of all the information around us. Everyone has the skill in varying degrees. The skill is reading. Yes, reading is the only mandatory skill needed to take advantage of the information age. How else can one assimilate all the knowledge available to us?

Now, let’s consider why people don’t realize reading is their barrier to the information age. The simple answer would be the reason why they are reading. There are two main reasons why people read. The reasons are for pleasure and work.

People read for pleasure and leisure. There are thousands of books published every year on a multitude of topics. The book stores are full of books and magazines. You can read fiction and or non-fiction. The thing about doing anything for pleasure and leisure is you get to it when you can. And there is nothing wrong with that.

People read work related material. There is email, reports, and paperwork of all kinds to be read. And much of this reading can be tedious and boring. Work related reading can cause fatigue and negatively impact reading for any other reason. Outside of the regular reading material for work there are trade journals and magazines to be read. Truly, this kind of reading is enjoyable but your employer may not allot time for it on the clock.

You need to be aware of another kind of reading. This kind of reading will allow you to take advantage of the information age. You should be reading for expert knowledge. Now reading for expert knowledge is not quite the same as reading for leisure or for the job. Reading for expert knowledge has a different end result. The end result of reading for knowledge is to become an authority on a topic. When you read this way, you are reading to gain insights, skills, tips, hints, tricks of the trade, and an insider’s working knowledge of a topic.

What type of fisherman are you? Are you satisfied go out and drop your fishing line and be totally unconcerned about if you catch anything or not? Is the time that you spend with your family, friends or even by your self enjoying nature what your trip is really all about? If you don’t caught anything that’s fine-you can always stop at the fish shop on the way home, but it would be nice if you caught something. Or do you feel like your trip’s been ruined because you didn’t caught anything, and go home frustrated. Or is fishing how you make your living, either by catching fish or taking customers out to fish? If you take a customer out to do some deep sea fishing, it would be much better to bring home a happy customer with his catch, who could be possibly a repeat customer or tells his friends about how great his trip was bringing you additional work. A frustrated customer will think twice about using your services again and when planning his next trip, might go elsewhere and may be steering other potential customers away from you. What if there was a way to make sure you go where the fish are? What if there was a way to guarantee that you would catch your limit, to be able to ensure that your customers will go home happy and raving about your great service.

With GPS technology it is now possible to go where the fish are and to remember the spot so you can relocate it. The other good thing about using a GPS while on the water is safety. You can enter the spot where you put your boat in the water in the memory of your GPS unit. Most GPS units hold at least 500 landmarks or areas where you want to get to. If you run into fog or bad weather you should be able to find your way back. Also if you stay out longer than expected you can find your way back in the dark. If you run into an emergency while on the water, you can call someone and let them know your coordinates, and then they could find you. If someone falls overboard a GPS unit can pinpoint the exact area where the incident happened and helping rescue crews with their rescue. This allows you to enjoy your day and not worry about getting back to land safely.

A chart plotter GPS with a map chip can give you your position relative to land features, water depth, and harbor entrances. Using a GPS with a water depth can allow you to follow the bottom looking for fish. It is also possible to let others know about a spot that you have found by using GPS coordinates.
