| Bluetooth Adapter Bluetooth | | | | InW (ie 10 minus 9 th power W), the receiver |
| Bluetooth Adapter Bluetooth (Bluetooth) is a | | | | sensitivity of-60dBm. |
| wireless network transmission technology originally | | | | Bluetooth adapter uses universal short-range |
| used to replace the infrared. Compared with the | | | | wireless connectivity technology, use and |
| infrared technology, Bluetooth can transmit data | | | | microwave, remote control, as well as some |
| without alignment, the transmission distance of | | | | civilian the same 2.4GHz wireless communication |
| less than 10 meters (infrared transmission | | | | equipment near the toll-free, apply for the radio |
| distance of a few meters or less). In the signal | | | | frequency bands, in order to avoid this band |
| amplifier with the help of communication distance | | | | caused by a number of electronic devices the |
| and even up to 100 meters. Bluetooth technology | | | | mutual interference, and thus 1600 times difficult |
| is ideal for low power consumption of digital | | | | hopping and encryption security technology. |
| devices to share data with each other, such as | | | | Bluetooth adapter with the convenience of the |
| mobile phones, handheld computers. Moreover, | | | | many advantages of low-cost, mainly used in the |
| Bluetooth devices can transmit sound, such as | | | | following areas: |
| Bluetooth headsets. Widely used in the Bluetooth | | | | 1. File Transfer - to transfer files across different |
| specification version 1.1, the mature, bandwidth of | | | | software platforms (such as the card transmitted |
| about 1Mbps (USB1.1 interface bandwidth of | | | | from the mobile phone Pocket PC) |
| 12Mbps, USB2.0 interface bandwidth of 480Mbps, | | | | 2. Data synchronization - support for different |
| LAN bandwidth 10Mbps/100Mbps/1000Mbps, | | | | operating platforms of the Information |
| Firewire IEEE1394 bandwidth of 400Mbps. So said | | | | Synchronization (such as handheld computers and |
| that Bluetooth is suitable for small file transfer | | | | computer data synchronization, mobile phone and |
| (10MB below pictures, ring tones, e-books, | | | | computer data synchronization between) |
| manuscripts, etc.) to facilitate and speed have | | | | 3. Voice transmission - transmission via Bluetooth |

| Bluetooth adapter that can be applied to a variety | | | | headsets) |
| of digital products Bluetooth device interface | | | | 4. Analog Serial - by wireless means to achieve |
| converter. Market at present, there are essentially | | | | analog RS-232 serial transfer protocol (such as |
| USB interface, Bluetooth adapter, and USB | | | | support for Bluetooth printers) |
| interface with plug and play features to distinguish | | | | 5. Dial-Up Networking - Call received a modem to |
| if from the interface, then the type of Bluetooth | | | | connect to the Internet (such as computer via |
| adapter also a kind: the Bluetooth USB Adapter . | | | | Bluetooth mobile phone GPRS / CDMA Internet) |
| Bluetooth USB Adapter except, of course, there | | | | 6. Bluetooth Network - Bluetooth to establish a |

| encryption security technology, transmission rates | | | | Features: |
| in the 432Kbps to 721Kbps range. Widely used in | | | | Bluetooth support new technologies, Broadcom |
| the Bluetooth specification version 1.1, the mature, | | | | 2045 chip, to provide a legal address code; |
| bandwidth of about 1Mbps, which is also some | | | | - Genuine with Widcomm 4.0 driver software, the |
| versions of up to 2Mbps. | | | | perfect support for VISTA |

| transfer data faster. Mostly currently on the | | | | -USB bus-powered, no need to take power, LED |
| market 10M and 100M PCI-bus. With the increasing | | | | lights instructions; |
| popularity of USB interface, the existing Bluetooth | | | | - Ultra-thin ultra-light, built-in antenna, without USB |

| developed a new type of serial interface, it has | | | | - Transfer Rate: 3Mbit / s (EDR), transmission |
| become a computer and redeployment of | | | | speed faster; |
| equipment (such as: keyboard, tape drives, | | | | - The scope of work as far as: 100m; |
| printers, writable CD-ROM, etc.) between the | | | | - Security: 128 bits security model; |
