Bluetooth Adapter Bluetooth

Bluetooth Adapter Bluetooth (Bluetooth) is a wireless network transmission technology originally used to replace the infrared. Compared with the infrared technology, Bluetooth can transmit data without alignment, the transmission distance of less than 10 meters (infrared transmission distance of a few meters or less). In the signal amplifier with the help of communication distance and even up to 100 meters. Bluetooth technology is ideal for low power consumption of digital devices to share data with each other, such as mobile phones, handheld computers. Moreover, Bluetooth devices can transmit sound, such as Bluetooth headsets. Widely used in the Bluetooth specification version 1.1, the mature, bandwidth of about 1Mbps (USB1.1 interface bandwidth of 12Mbps, USB2.0 interface bandwidth of 480Mbps, LAN bandwidth 10Mbps/100Mbps/1000Mbps, Firewire IEEE1394 bandwidth of 400Mbps. So said that Bluetooth is suitable for small file transfer (10MB below pictures, ring tones, e-books, manuscripts, etc.) to facilitate and speed have both. the latest version is 2.1 + EDR version.
Bluetooth adapter that can be applied to a variety of digital products Bluetooth device interface converter. Market at present, there are essentially USB interface, Bluetooth adapter, and USB interface with plug and play features to distinguish if from the interface, then the type of Bluetooth adapter also a kind: the Bluetooth USB Adapter . Bluetooth USB Adapter except, of course, there are Bluetooth adapter headsets, Bluetooth, etc. Mike.
The so-called “Bluetooth” (Bluetooth), is a kind of universal adoption of a global short-range wireless connectivity technology, using the same 2.4GHz microwave near the toll-free, apply for the radio frequency bands. To avoid this band caused by a number of electronic devices interfere with each other, and thus 1600 times difficult hopping and encryption security technology, transmission rates in the 432Kbps to 721Kbps range. Widely used in the Bluetooth specification version 1.1, the mature, bandwidth of about 1Mbps, which is also some versions of up to 2Mbps.
Line types can be divided into ISA bus, PCI bus and USB bus. ISA-bus with 16-bit transfer data, the nominal rate to reach 10M. PCI bus to a 32-bit transfer data faster. Mostly currently on the market 10M and 100M PCI-bus. With the increasing popularity of USB interface, the existing Bluetooth adapter is basically for the USB bus.
USB bus or Universal Serial Bus, Universal Serial Bus, is IBM, Intel, Microsoft, Compaq, NEC and so on for several world famous companies jointly developed a new type of serial interface, it has become a computer and redeployment of equipment (such as: keyboard, tape drives, printers, writable CD-ROM, etc.) between the standard interface. The interface is not only a good load capacity, and ease of use, Ye Hao, with “plug and play” function, cascading up to 127 peripherals to support real-time audio playback and image compression.
In ensuring that the required bit error rate under the conditions of receiving the required minimum input power. DBm receiver sensitivity tends to be used to indicate that it is based on lmW optical power based on the absolute laptop ac adapter , or write to Which, Pmin refers to a given bit error rate conditions, the receiver can receive the minimum average power. For example, in a given bit error rate of 10 negative 9-th power, the receiver can receive a minimum average power InW (ie 10 minus 9 th power W), the receiver sensitivity of-60dBm.
Bluetooth adapter uses universal short-range wireless connectivity technology, use and microwave, remote control, as well as some civilian the same 2.4GHz wireless communication equipment near the toll-free, apply for the radio frequency bands, in order to avoid this band caused by a number of electronic devices the mutual interference, and thus 1600 times difficult hopping and encryption security technology.
Bluetooth adapter with the convenience of the many advantages of low-cost, mainly used in the following areas:
1. File Transfer – to transfer files across different software platforms (such as the card transmitted from the mobile phone Pocket PC)
2. Data synchronization – support for different operating platforms of the Information Synchronization (such as handheld computers and computer data synchronization, mobile phone and computer data synchronization between)
3. Voice transmission – transmission via Bluetooth audio information (such as support for Bluetooth headsets)
4. Analog Serial – by wireless means to achieve analog RS-232 serial transfer protocol (such as support for Bluetooth printers)
5. Dial-Up Networking – Call received a modem to connect to the Internet (such as computer via Bluetooth mobile phone GPRS / CDMA Internet)
6. Bluetooth Network – Bluetooth to establish a virtual network (such as the formation of Bluetooth wireless Peer to Peer) 7. File Exchange – business cards, conference matters, to-do exchange
8. SMS management – to send SMS via computer editing
9. File Manager – Edit categorized on the phone contacts, upload and download information, ring tones, pictures
