Bluetooth Adapter

Bluetooth Adapter to a variety of digital products can be applied to the Bluetooth device interface converter. Bluetooth adapter using the universal short distance wireless connection technology, use and microwave, remote control and some civil wireless communication equipment the same 2.4GHz near free, free to apply for a radio frequency band, to avoid this electronic device is numerous and caused by mutual interference, resulting in the one thousand six hundred high frequency hopping and encryption security technology.

Bluetooth adapter.

Bluetooth is a wireless network transmission technology, which is used to replace the infrared. Compared with infrared technology, Bluetooth without alignment can transmit data, transmission distance is less than 10 meters ( infrared transmission distance in a few meters). In the amplifier 's help, communication distance and even up to 100 meters. Bluetooth technology is very suitable for low power consumption digital equipment mutual sharing of data, such as mobile phone, palmtop computer. Moreover, between Bluetooth devices can transmit sound, such as a Bluetooth headset. Bluetooth specification widely used mature version 1.1, a bandwidth of approximately 1Mbps ( USB1.1 interface bandwidth of 12Mbps, USB2.0 interface bandwidth of 480Mbps, LAN bandwidth for 10Mbps / 100Mbps / 1000Mbps, the IEEE1394 bandwidth of 400Mbps. Therefore, Bluetooth is very suitable for transmitting small file ( 10MB following pictures, bell, book, manuscript, and so on ) convenience and speed at. The latest version is version 2.1+EDR. Due to the current market some blue

Tooth adapter basically as USB interface, and USB interface with plug-and-play features, if from the interface to distinguish words, Bluetooth adapter type is a: Bluetooth USB adapter. Of course, in addition to Bluetooth USB adapter, Bluetooth headset, Bluetooth and Mike etc..

Basic information

The so-called" Bluetooth", is a kind of the universal short distance wireless connection technology, use and microwave near 2.4GHz free, free to apply for a radio frequency band. To avoid this, many electronic device caused by mutual interference, resulting in the one thousand six hundred high frequency hopping and encryption security technology, transmission rate in 432Kbps to 721Kbps ranging. Bluetooth specification widely used mature version 1.1, a bandwidth of approximately 1Mbps, and also some version of 2Mbps.

Classification

Line type can be divided into the ISA bus, PCI bus and USB bus.

ISA bus to transmit data 16 bits, the nominal speed can reach 10M.

In 32 PCI bus to transmit data, faster. Currently on the market are mostly 10M and 100M PCI bus. With the gradual popularization of USB interface, the existing Bluetooth adapter basically for USB bus.

USB bus or Universal Serial Bus, universal serial bus, IBM, Intel, Microsoft, Compaq, NEC and other major world famous manufacturers jointly develop a new type of serial interface, it has become the computer and external equipment ( such as: keyboards, tape machine, printer, can be written to the disc machine) between the standard interface. The interface not only load capacity, and ease of use or, having a" plug-and-play " function, can be connected in series 127 peripherals, support for real-time audio playback and image compression.
