How Bluetooth Will Help YouThe Inner Workings Of The Bluetooth
By Lawrence Cheney
Bluetooth is a high speed, low powered wireless link technology that's designed to connect phones or other portable equipment together with little to no work required by the user. Unlike infrared, Bluetooth doesn't require line of site positioning to work.
Current prototype circuits are contained on a board that is 0.9 cm square, with a much smaller circuit board being developed.
When one bluetooth device comes in contact with another, they will automatically exchange addresses and details of capability. Then, they can establish a 1 MB link with security that they will use as required. The protocols involved with handle both data and voice, with a very flexible topography.
The technology achieves its goal by embedding tiny,non expensive short range tranceivers into the devices available today. The radio operates on the 2.45 GHz frequency band, and supports up to 721 KBps, along with three voice channels.
Each devices offers a unique 48 bit address from the IEEE 802 standard, with the connections being point to point or multipoint. The max range is 10 meters, although it can be extended to 100 meters by increasing the power. The devices are also protected from radio interference by changing their frequencies, also known as frequency hopping.
Whats important, is the fact that Bluetooth devices wont drain battery life. The specification targets power consumption of the device, limiting the drain on the battery. The radio chip will consume only 0.3mA in stand by mode, which is less than 5% of the power that standard phones use.
Bluetooth will also guarantee security at the bit level. The authentification is controlled by the user via a 128 bit key. The radio signals can be coded with anything up to 128 bit. With the frequency hopping, Bluetooth is already very hard to listen into.
The baseband protocol is a combination of both circuit and packet switches. Slots can be reserved for synchronous packets as well. Each packet will be transmitted in a different hop frequency. Normally, a packet covers a single slot although it can be extended to cover up to five slots.
Bluetooth can also support data channels of up to three simultaneous voice channels. Therefore,its possible to transfer the data while you talk at the same time. Each individual voice channel will support 64 KB.
From a technical standpoint, Bluetooth is very different indeed. Its the best wireless method in the world, surpassing even infrared. For communication on the go, Bluetooth is indeed very hard to compete with.

What Bluetooth Technology OffersAll About Bluetooth
By Lee MacRae
The technology known as Bluetooth eliminates messy wires that tangle our everyday lives. Being able to stream your favorite music and connecting devices 30 feet apart are just the start of what Bluetooth can do for you. Let us teach you all about the wonderful world of Bluetooth.
Bluetooth Headsets The Bluetooth enabled headset offers a number of advantages to that of the standard style of headset. Many people find it great to wear it and use it as a hands-free device for cell phones with Bluetooth capabilities. You can easily put your cell phone in a handbag, your pants pocket or in a jacket pocket and it is very easy to accept and make calls. You can use it like any other cell phone
but with much more safety because of the Bluetooth headset.
The Bluetooth Dongle This device simply gives you a way to connect Bluetooth devices to a host computer that does not already have Bluetooth capabilities. The dongle then provides a way to allow your laptop or personal computer to talk with Bluetooth capable equipment. This allows you things like connection to the Internet or to be able to transfer images and data within a range of 10 metres. Bluetooth technology is great for sharing files, transferring images, for printing, exchanging your data or synchronizing various devices. You can even use the dongle with a Bluetooth headset to give yourself Skype calls on the Internet.
Bluetooth GPS This technology is small in size and light weight in half. Being very portable it is ideal for use in urban environments, hiking, biking or finding your way in a new city area. They can be used to find parking spots, petrol stations, restaurants, motels or hotels when traveling, and some have the ability for an automatic alert option as you reach your destination. In addition, you can configure it to work with a number of devices from Pocket PCs to Palm devices as well a smart mobile phones. Some of them even have instructions spoken in more than 30 languages making them ideal for tourists or hikers and campers.
To help you appreciate how important Bluetooth technology has become in the world today, you can find a wireless Wii remote control that incorporates Bluetooth software
to the Wii console within the amazing distance of 30 feet. That means Bluetooth technology is today's modern technology that you should use as well.
