Procedimiento para conectar un dispositivo bluetooth
Apple has its strategy right on the money and Bluetooth is nothing but a small convenience for consumer but not for Apple's master plan, and that?s why you don?t see Apple dancing over Bluetooth. Bluetooth is commonly used to transfer sound data with telephones (i.e. Bluetooth is now available in most modern handsets due to its simple interface, free operation and low-power consumption. You can use Bluetooth to send photos, ringtones and music to your PC or connect you handset with a wireless headset to make calls or listen to music.
The next hot area Bluetooth is moving to: speakers. There are a ton of portable wireless speakers available for playing music from your cell phone out loud. Bluetooth is now gaining acceptance for applications other than cable replacement. With Bluetooth, drivers can connect a wireless headset to a mobile telephone and operate more safely in a "hands free" mode, or connect to a PDA right from the vehicle. A data transmission technology comparable to Bluetooth is IrDA or infrared communication much like what your remote control devices use to control the TV, stereo, air conditioner etc. The big drawback of this type of technology, however, is the requirement that the two devices establishing a connection must be within sight of one another for transmission to take place.

Bluetooth is named after this king to show the importance of bringing together different devices and communicating with one another. But, like DECT, the important thing about Bluetooth is that it carried voice information digitally, making it equally suitable for transferring data between devices. With just about everything going digital, including music, photographs and video clips, it made Bluetooth the ideal choice for transferring these digital media wirelessly from one device to another. Bluetooth is a cable replacement technology, designed to connect paired devices within 10 meters of each other. Given limited range and application, many incorrectly discount Bluetooth as a serious business threat.
In contrast to other communications standards, which can be proprietary, licensed, and costly, Bluetooth is open-standard, meaning that it is royalty-free and can be used by anyone. The expected user base is on the order of 1.5 billion devices by 2005, with a market of $5 billion in sales. Bluetooth is turned off. In this mode, you can neither send nor receive information using Bluetooth. The magic of bluetooth is that it simultaneously handles both voice and data transmissions.
There are more than 1800 manufacturers worldwide and the Bluetooth is built into over 500 millions of devices in 2007. IMS research predicts the market growth of Bluetooth to increase by 300% in the next 5 years. Bluetooth is the name of a wireless technology standard for connecting devices, set to replace cables. It uses radio frequencies in the 2.45 GHz range to transmit information over short distances of generally 33 feet (10 meters) or less. Transferring files via Bluetooth is a quick process that makes things very convenient when using Bluetooth enabled products. Cell phones, digital camcorders, and PDAs are just some of the many products that use Bluetooth technology and now you can transfer files from these devices to your computer with no cables or wires!
Considering the design philosophy behind Bluetooth, even the 10m range is adequate for the purposes Bluetooth is intended for. Later versions of the Bluetooth spec may allow longer ranges. One of my favorite uses of Bluetooth is to control my computer from across the room. A program called Salling Clicker (Shareware, $23.95) allows me to use my PDA or phone to do just that. Bluetooth is an emerging short range, wireless networking standard. Using Bluetooth communication interfaces, a collection of devices can interconnect to form a scatternet.
However, regular Bluetooth is not fast enough for quality stereo sound. Bluetooth is the answer. More simply, Bluetooth is a low-power, spread-spectrum technology that uses frequency-hopping to ensure speedy, short-range wireless data transfer of up to 720 kbps at a range of 30-100 feet. Intended as a replacement for the short-range data cable, Bluetooth's original conception was as a wireless peripheral interface, linking print- ers, monitors, keyboards, and other peripheral devices to the CPU.
If the Bluetooth is anything like the iPhone implementation, it wont allow file transfer or anything of that sort. The Bluetooth on the iPhone allows Bluetooth headphones, speakers, and possibly song control (although I'm not sure about that). Because most devices (such as handhelds) have unused serial ports on their motherboards, adding Bluetooth is very easy. It can be as "easy" as soldering four pins total to the motherboard. The competition between Bluetooth and conventional radio based data networks (WLAN), such as 802.11 based networks, grows as Bluetooth is being developed and radio LAN becomes less expensive. The overlap between the two widens but in some aspects there is still a gap: High speed and large coverage require expensive components; Bluetooth is more cost efficient with lower speed and smaller coverage.
Solutions of both types are perfectly feasible, but Bluetooth is neither of them. Not with some salesman pre-loaded bluetooth device in store, but get them to do it with your own phone, there and then, and see what Bluetooth is all REALLY about. Its really a cool technology that allows you to do much more than you'd think it can do . Bluetooth is a latest trend as a channel for M-Commerce transaction. This paper explores the possibilities of latest trends in Bluetooth and its feasibility with M-commerce.
And Bluetooth is now starting to see use in industrial and retail environments, where being tethered could hinder business. Bluetooth is the answer. Bluetooth is a wireless protocol that was named after a 10th-century king, Harald Blatand (or, in English, Harold Bluetooth). King Blatand was instrumental in unifying previously warring tribes in what are now Norway, Denmark and Sweden.
Bluetooth is essentially a short-range wireless technology with working distances of about 100 feet. Data transfer speeds for Bluetooth range from 0.5 to 1.5 megabits per second. Integrated Bluetooth is now present in a broad range of cell phones--from high-end smartphones to low-end functional models. Of course, cell phone Bluetooth usage is not limited to just headsets--you can also use Bluetooth to stream music wirelessly, connect to the Web, transfer files, and more. The only true competitor of Bluetooth is infrared—a technology that is inferior due to its line-of-sight requirements. When using Bluetooth, you don't have to point your PDA at another's in order to transfer your business card.
Furthermore, Bluetooth is designed for short-range communication (nominal range of about 10m). In other words, the way I want to use Bluetooth is as a computer-to-computer connection. Most people I talk to see it that way, too. Bluetooth is becoming more and more popular, and it?s time to examine its security implications. Can it be made secure?
One of the distinctive elements of Bluetooth is that is uses very much less power than Wi-Fi. Class 3 devices (such as are in PDAs, phones, headsets, etc) transmit a very low power signal (1 mW) and only transmit intermittently when in standby mode, saving even more power. Because of this difference, Bluetooth is more typically found supported in wireless phones and personal devices. Bluetooth is a cheap way for all kinds of devices to communicate without being in eyesight of one another, and is commonly used today in wireless cell phones and headsets. This alone is huge because it's so much safer to drive a car and talk on a phone using one of these ?
Bluetooth is a technology I use every day in some form or another. Trying to pin down just one favorite is like trying to pick which child is your favorite. I am restarting my computer all the time, and if I don’t, then the bluetooth is not available and putting my computer into sleep mode is impossible!!! Seriously, apple needs to get with it and fix this problem. Bluetooth is the most successful short-range wireless technology in use today, embedded in over 50 percent of cellular handsets. Bluetooth low energy is the natural evolution of this successful technology.
This Bluetooth is packed with features that make this headset one of the most advanced in the market. Comfort is key to the BT125 and the ear hook is made of a very lightweight material, which won’t be a nuisance. Bluetooth is the name of a protocol for a short range (10 meter) frequency-hopping 2.4 GHz radio link between wireless devices such as a mobile phone and a PC. The idea is to make connections between different electronic items much easier and simpler, and without a lot of operator intervention. While Bluetooth is a standard, headset design and experience are not.
As a network protocol uniting many different types of devices, Bluetooth is only useful when it enjoys wide industry support. In reality, Bluetooth is an industry standard supported by all major electronics and computer vendors. By default, Bluetooth is normally switched off to save battery power. I come from a pci background and although I'm sure that there is more complicated stuff out there, I would venture to say that bluetooth is one of the more complicated networking spec's you can attempt to learn. However, if the bluetooth market is going to explode to something like $3bn by 2007, then thousands of engineers will have to understand the spec well enough to be able to design with it.
In this situation, using Bluetooth is the ideal solution. Bluetooth enables you to set up an ad hoc, wireless network instantly, without the need for a network infrastructure. In short, Bluetooth is a short-range radio frequency standard that’s designed to replace cables. It’s not meant to be a long-range, high-bandwidth beast like Wi-Fi; instead, Bluetooth lets you efficiently and easily transfer blocks of data to and from small digital devices, such as PDAs, keyboards, cameras, printers, headsets, speakers, cell phones, and much more.
