Play Bluetooth, first you want to know Bluetooth! Author: great
What is Bluetooth? What can I do with Bluetooth? Every time you hear this ear-cried scientific name, you may not be able to specifically analyze the April Fool's Day. Who do you want to? Small apartment main lineup reveals multimedia interactive English English like it is. In fact, Bluetooth technology makes many 3C products more convenient, but can not only replace traditional transmission lines, but also have many fresh gameplay.
Here, we will take you to quickly understand the working principle of Bluetooth. After a preliminary understanding of Bluetooth, we will tell you how to make your own computer with advanced Bluetooth function, lend and 3C product with Bluetooth function. Wireless connection, while providing several creative gameplay, let Bluetooth technology enhance your life! Let's go!
I believe that you must have heard of Bluetooth this a little dazzling scientific noun, and also knows some high-end mobile phones and headphones with Bluetooth function. What is Bluetooth? What convenience can you bring? I believe you must know.
All devices - including laptops, mice, printers, mobile phones, PDAs, digital cameras, etc., can be exchanged for voice and data through "Bluetooth" technology. At the same time, it can also be connected to the outside through an access point (such as: PSTN, ISDN, LAN, ADSL).
Bluetooth = wireless transmission line
Bluetooth technology is an open global specification for wireless data and voice communication. Its instining is to establish a universal radio empty interface for a communication environment between fixed devices or mobile devices, and further communicate with computer technology. Combining, various 3C devices can communicate or operate in a near-distance range without wires or cables. Simply put, Bluetooth technology is a technique that utilizes low power radio to transmit data between various 3C devices. The biggest benefit is that it can replace a variety of messy transmission lines.
Never subject to the transmission line
The traditional transmission line has a length limit, there is a certain requirement for the location of the equipment, the transmission line is too short, the device cannot be too far from the computer; the transmission line is too long to have a wealth, trouble and not beautiful. After switching to Bluetooth wireless transmission, you can break through the transfer line, the computer should be online, the phone does not have to be placed next to the computer, even at all, do not need to take it from the pocket, as long as you can transfer it within ten meters away, you can freely transfer. There is no restriction.
Get rid of unplug connection
When the equipment is more, the transmission line may become a group, it is not easy to organize, the inconvenience is inconvenient, and it is not anger. The pulling transmission line is even more bitter, not only to remember the corresponding relationship between the plugs and sockets of different shapes, sometimes you have to explore half a day behind your computer. Using Bluetooth replaces the traditional transmission line, not only say goodbye to the messy transmission line, not to go to the corresponding relationship between the socket and plug shape, as long as the simplicity of several mouse operations or buttons, you can set up wireless transmission between the devices. It is very convenient to pass the channel.
