Bluetooth technology to communicate with the equipment, determine the frequency roll into gear mode "caller" and its communication opponent, "by taking sides." Caller before they take the same time by the parties and seven communication. Therefore, the caller can be taken together with the seven parties were famous for the 8 devices to connect Piconet (sawtooth network) subnet. Piconet taken by the parties within the same time as the subject to take more than two parties Piconet. In July 1999, announced the official Bluetooth specification BluetoothVersion 1.0. Comply with the specifications of cell phones and laptop computers will be listed in late 1999 or early 2000. Bluetooth technology products make claims that the companies are growing, the current Bluetooth standards bodies "BluetoothSIG (Special Interest mix)" members of the enterprises has increased to 800 or more. The antenna is stored at the second floor of the warehouse of cell phone jammer.
The so-called Bluetooth (Bluetooth) technology, is actually a short-range wireless communications technology, the use of "Bluetooth" technology, can effectively simplify the Pocket PC, laptop and cell phone handsets and other mobile communication terminal for communication between devices, but also successfully These simplify the communication between devices and the Internet, so that these modern communication equipment and data transmission between the Internet more quickly and efficiently, widen the road for wireless communications. Put it plainly, it is easily some of the Bluetooth technology makes modern mobile communication devices and portable computer equipment, do not have to be able to use the cable network, and enables wireless access to the Internet, its practical application can also be extended to a variety of home appliances, consumer electronics products such as information appliances and automobiles, to form a huge wireless communications network. The host of china cell phone jammer is kept in the first floor of the warehouse of cell phone jammer .The warehouse of cell phone jammer will be closed at four o’clock.
IE browser produced by Microsoft, a browser, and using free (and Win) bundled manner to the user, that is, as long as you use the Win family of operating systems would certainly have the IE browser, but also because So, IE has occupied the vast majority of personal computer browser share, other non-IE (core) browser such as Netscape NETSCAPE, OPERA and FIREFOX also individual users in general are rare. Is a low-power short-range wireless connectivity technology standard in lieu of that, "Bluetooth" is taken from a unified in the 10th century Danish king, Harald II, (Harald) of the nickname, the "Bluetooth" (Bluetooth). "Bluetooth" technology is the first five world-renowned advocate of computer and communications companies: Ericsson, Ericsson, International Business Machines IBM, Intel, Intel, Nokia Nokia, and Toshiba Toshiba. And in May 1998 set up a "Bluetooth" special interest group (Bluetooth Special Interest Group-SIG), the organization adopted a free transfer to industry of the patented technology strategy to achieve its goal of global harmonization of standards. The worker needs to get the needed cell phone jammer before it is closed.
The goal is to achieve maximum data transfer speed 1Mbps (the effective transmission speed of 721kbps), the maximum transmission distance of 10 meters, the user can not have been allowed to use the 2.4GHz ISM (industrial, scientific, medical) band, set up in its 79 channel bandwidth of 1MHz, with a frequency of 1,600 times per second switching, hobbing (hobbing) mode technology to achieve spread spectrum radio transceiver. This is the origin and characteristics of Bluetooth technology.
