What Are Bluetooth Profiles?
Bluetooth profiles are the electrical components needed to operate and work with other equipment. These profiles are broken up into different categories. There are thirty-three different profiles. All of these profiles can work with each other to control various electronic equipment in the home or in the office. Having this technology in one's home will make watching a movie or sending a fax or e-mail much more enjoyable and accessible. Being able to work on different projects at the same time and being able to communicate quickly is how people who work from home get things done. Profiles are merely signals used by certain pieces of equipment to make it work and work with other pieces.
The Advanced Audio Distribution Profile (A2DP) is used when installing sound equipment. Wireless headsets, stereo systems, speakers, and car amplifies are all controlled under this profile. Profiles are a way to keep frequencies separate. If not, then one system would control another, which would result in chaos. People would be controlling other people's equipment, which would make many people very angry. This profile also controls options like surround sound on an entertainment unit. This is an important profile because sound is so important in people's lives.
The Audio/Video Distribution Transport Protocol ( AVRCP) is the profile that remote controls work from. One remote can be used for all audio/video equipment in the home or office. This includes volume control, which works with the sound profile. These profiles work together to provide television and music at the touch of a button. The remote also controls television channels, radio channels, programming DVD players and CD players. Having one remote can be a lifesaver. From the comfort of one's easy chair, all equipment can be controlled to suit the person's needs.
| Quote of the Day |
Being so wrong about her makes me wonder now how often I am utterly wrong about myself. And how wrong she might have been about her mother, how wrong he might have been about his father, how much of family life is a vast web of misunderstandings, a tinted and touched-up family portrait, an accurate representation of fact that leaves out only the essential truth.

A Basic Imaging Profile is used mainly for the sending and receiving of images. This means being able to take a picture on a cell phone, downloading it onto a computer, and then displaying it on a television set. This is great for analyzing a picture or to share it with friends and family. Taking a picture on a cell phone and sending it to one's home computer is a great way to save a picture without using all the cell phone's memory. Being able to transport pictures through different devices is fun. Watching movies can be done on a cell phone, computer, and television.
There are other profiles that are used for the home office. Profiles that work with printers, faxes, e-mail, and other devices are all useful. Printing from one's cell phone saves time. If an e-mail comes through and it needs to be printed, the e-mail can be forwarded to the printer using Bluetooth. This technology has made life easier. People lose less information; memos and other messages can be printed faster and distributed to the right people. Other uses for this technology are for business presentation. Laser pointers, overhead projectors, and other computer programs can all be controlled from a central remote that is wireless. Without the wires, presentations can be given almost anywhere. This is very convenient and could save money on audio/visual equipment.
Bluetooth technology works on secure networks. This is one reason why profiles exist. Keeping categories separate maintains user privacy and also sets up security checkpoints in case someone is trying to access information they should not be looking at. This is a concern for those who are willing to use the technology, but are weary of sending confidential information over the radio frequencies. By using profiles, the network is broken up like a puzzle. Only when a person has all the pieces can they put a picture together. Security is a serious matter and one that is dealt with everyday.
Profiles come with the equipment. It is important to be aware of the different types of profiles because one may be needed by another to be successful. A remote is not of any use if it cannot control the volume and sound quality. Making sure the profiles will work together is essential. In the office, having different profiles enables communication to take place at a much faster rate than before. Pictures, faxes, e-mail, and other means of communication can only be improved using Bluetooth technology.
