Bluetooth Basics

Posted on November 7th, 2008 in Bluetooth | No Comments

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 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.

Bluetooth: Connect Without Cables

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

Each device will simultaneously communicate with up to seven other devices within a single Private Area Network, meaning that each device can also belong to several PANs simultaneously. The PANs are dynamically established as Bluetooth enabled devices enter and leave the proximity of radio.

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

Bluetooth And Apple

Posted on November 1st, 2008 in Bluetooth | 1 Comment

The new Apple powerbook G4 are among the first computers to offer Bluetooth technology 2.0+EDR. The 2.0+EDR technology, which still backwards compatible with 1.0, is up to three times faster than previous versions, offering maximum data rate transfers of up to 3 MBps.  Being the first company to certify a system with 2.0+EDR, Apple continues to make great use of the Bluetooth technology.

Full support
In addition to the powerbook G4 portables, there are other Bluetooth enabled computers available from Apple, including the iBook, iMac G5, eMac, and the Power Mac G5.

Making life easier
When you turn the Bluetooth feature on, your Mac can easily perform a file transfer or even a synchronization.  From the Bluetooth selection menu, you can choose to either send a file or browse devices, quickly and easily.  Or, you can click the sync button in iSync to update your cell phone or Palm OS handheld.

The Mac and GSM/GPRS mobile phone with Bluetooth work to make each other more useful.  By using iSync, you can keep your phone updated without having to type any info, as you can keep the information in the more manageable address book on your Mac instead.

You can also use your Bluetooth enabled Mac to print documents and digital images to select a printer that also supports the technology of Bluetooth.  Or, you can also use a headset to talk to your friends during an iChat session.

Your Mac also has the ability to use Bluetooth technology to communicate with your Palm OS handheld.  This way, you can perform a HotSync operation without using any cables.  You can also send your business card or calendar events directly to someone else’s handheld using the technology of Bluetooth.

The implementation of Bluetooth by Apple is the latest in a series of moves that have caused great shift in the computer industry.  Apple established USB as the standard interface with the launching of the first Mac back in 1998.

Since then, Apple established the 802.11 wireless standard of networking with the launch of the iBook and AirPort in 1999.  During 2003, Apple launched AirPort Extreme, which was based on the new 802.11g high speed technology of wireless.

Now, Bluetooth helps to further strengthen the dominant position of the Mac in wireless communications, helping to preserve Apple’s reputation for being the first to market with innovative technology that integrates right into the operating system.

Bluetooth Technical Operations

Posted on October 31st, 2008 in Bluetooth | No Comments

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.

Bluetooth GPS Receiver

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 transceivers into the devices available today. The radio operates on the 2.45 GHz frequency band, and supports up to 721KBps, 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.

Advantages And Disadvantages of Bluetooth

Posted on October 29th, 2008 in Bluetooth | 1 Comment

Bluetooth has a lot to offer with an increasingly difficult market place. Bluetooth helps to bring with it the promise of freedom from the cables and simplicity in networking that has yet to be matched by Local Area Network.

In the key marketplace, of wireless and handheld devices, the closest competitor to Bluetooth is infrared. Infrared holds many key features, although the line of sight it provides doesn’t go through walls or through obstacles like that of the Bluetooth technology.

Unlike infrared, Bluetooth isn’t a line of sight and it provides ranges of up to 100 meters. Bluetooth is also low power and low processing with an overhead protocol. What this means, is that it’s ideal for integration into small battery powered devices. To put it short, the applications with Bluetooth are virtually endless.

Disadvantages
Bluetooth has several positive features and one would be extremely hard pressed to find downsides when given the current competition. The only real downsides are the data rate and security. Infrared can have data rates of up to 4 MBps, which provides very fast rates for data transfer, while Bluetooth only offers 1 MBps.
