Designed with an electrical device and produces every day is the problem of how to connect all these devices in connection always complicated. Traditionally, connections have always been on cable and lines, but even with this simple method, there are many different connection methods. In addition, the cables get in the way, especially with devices such as headsets. This means that wireless technology is especially for such devices. A good example is theBluetooth stereo headsets.
Bluetooth was created as a solution to this challenge connection. A uniform standard, and automatic wireless protocol that all devices could be used in the course content, facilitate and enable the devices and most of their products.
Unlike Bluetooth, the most popular method of wireless connection was previously infrared (IR). This option uses the low-cost low-frequency waves to transmit light signalsanother device. The system is to create simple and inexpensive, but it has disadvantages.
The main disadvantage is that a protocol is 12:59. A device that can connect to another device at any time. For example, think of a TV and a remote control. The equipment must be in line of sight. This creates other problems. If there are two devices at opposite ends of the room and people are around each other, this could cause interference andConnection Error.
Bluetooth, on the other hand, uses low-frequency radio signals. This can be received within a radius of 20 meters and does not require line of sight. In addition, multiple devices can connect to each other - another clear advantage over infrared.
Although there are many possible uses for IR, where the technique is more appropriate (like the TV remote control), use the connectivity of the infrared device in general is old and Bluetooth technology has been adopted. There wasOf course, many devices for which it would have been impossible using infrared. Think of Bluetooth headsets. This would be the phone to your laptop at any time point during the operation. He'd never worked with infrared technology, Bluetooth has the ability to speak freely in hands-free phone.
