What bluetooth adapter for pc to buy. Bluetooth Adapters

Bluetooth adapters- modern useful gadgets for creating an affordable wireless connection between various devices: tablets, mobile phones, smartphones, laptops, PCs, sound centers and TVs. Adapters create a reliable connection for fast exchange useful information, files and work commands.

Stable and high speed protocol wireless connection- Bluetooth. The choice of adapter directly depends on the specific tasks for the solution to which it is intended.

Peculiarities

Consumers often confuse two similar terms - Bluetooth and Wi-fi connection. If Bluetooth technology is used for remote transmission of data over short distances between different devices, then Wi fi technology is used to create a local computer network and organize remote access in Internet.

The maximum range of the adapters is 50-60 meters, so they are used in apartments, houses, offices and shops.

A similar technology is used to quickly exchange audio, video and text files, you can manage RAM, send and receive photos, manage work programs.

The module is connected without additional cables and adapter elements, via a standard USB port. The advantage of the module is the ability to transfer data at high speed. The modules are able to establish and maintain wireless communication even with short-term wave interference between devices.

Types of Bluetooth adapters

Modern electronics are manufactured with an installed module, but there is equipment that requires the use of additional equipment due to its design and technical features.

Bluetooth modules are presented in two types - internal and external. Each of them differs in functionality and installation method.

Internal

This type of device is a system board that is connected directly to the internal circuit of the reader. They are reliable, durable, but difficult to install. They are used for stationary PCs, laptops and speaker systems.

External

By design features similar to USB drives - installs into any USB port. The module is suitable for modern electronic gadgets, television and video equipment.

Ergonomic housing, ease of installation and safety of operation, combined with an affordable price, make such devices indispensable for creating local wireless networks and performing tasks of any complexity.

Characteristics of bluetooth adapters

Bluetooth technology is available in 5 versions. Each version provides a different baud rate, signal strength, stacks and profiles.

• 2.0 + EDR;
• 3.0 + HS;

The operating data transfer rate is 3–24 Mbit / s. The power of technology has the following parts: 1; 2.5 and 100 MW. This indicator affects the coverage radius with similar indicators. The unit of measurement is meter. Devices of 1 MW with a range of 1 meter. There are devices with a capacity of 2.5 MW on the market, with an impact radius of up to 12 meters.

The latest version of the equipment in 4.1 provides coverage with a radius of up to 60 meters.

When choosing a device, you need to take into account the power and range.

Connection working profiles

Profiles are functionality that is supported by various hardware.

Bluetooth technology supports the following profiles:

• GAP- intended to support the operation of other profiles, the security of the wireless connection.
• A2DP- intended for transmitting audio signals in a two-channel stream. It is necessary for sharing audio files, listening to music.
• HSP- used for wireless connection of a headset (headphones, microphone) - mono sound transmission at a speed of up to 64 kbps.
• AVRCP- used to control sound on playback devices.
• LAP- intended for the organization wireless network between two Bluetooth devices.
• DUN- the profile allows you to use your phone as a modem.
• HID- connection of a headset - a computer mouse and keyboard.
• OBEX FTP- profile for connecting to random access memory mobile and tablet technology from a laptop or PC.

Even if the transmitting and receiving devices support work with protocols, the codecs used are taken into account when choosing bluetooth equipment.

The number of various digital devices is growing every day. Many of them can and should interact with each other. Some do it less often, while the rest require an almost permanent connection to exchange information, files, commands. The most widespread and high-speed protocol for convenient, and most importantly - wireless, connection is the Bluetooth protocol.

If your device does not have a built-in Bluetooth module, you can use alternative options connections

It is this protocol that any smartphones, tablets, laptops, almost all televisions, multimedia centers, acoustics and even some types of kitchen appliances are equipped with today. That is why for efficient work and management of various gadgets or office, you may need to install Bluetooth on your computer. We will tell you how to choose a Bluetooth adapter for your computer, as well as how to install Bluetooth on your PC.

Bluetooth technology is the most common system wireless transmission data after Wi-Fi protocol. While Wi-Fi is used more for organizing local wireless Internet access, Bluetooth technology has established itself as the most efficient way to exchange information over short distances.

The range of receivers and transmitters operating under this protocol is gradually increasing, but today it does not yet exceed 60 meters. The technology can be used to transfer files, receive and transmit an audio signal, send and receive various kinds of commands. By connecting a computer and another device using this protocol, you can, for example, easily control internal memory smartphones, take ready-made pictures from the camera, control the TV, connect wireless speakers or headphones to the PC, and so on.

While a large number of modern devices are initially released with a pre-installed Bluetooth module, a PC for Windows control remain the least equipped with such modules. The main reason is that most computers are assembled from different components, and most often an adapter supporting this data transfer protocol must be installed separately.

Bluetooth adapters are of two types: internal (motherboards) and external (plugged into the USB connector - "whistles", visually similar to a classic USB flash drive). If your computer does not have such a communication channel with external devices, but you feel the need for it, you can purchase an external adapter separately. Even a novice user can install, connect and configure it. We will describe below how to choose such a device and how to connect it to a PC.

When choosing a Bluetooth adapter for your computer, we recommend that you pay attention to several key parameters. One of the most important is the range of the wireless signal. Depending on the distance from the PC there are or may be the devices to which you want to connect, choose an adapter with the appropriate range. The maximum distance at which the adapter can establish a connection with devices directly depends on the version of the Bluetooth protocol that it supports. The higher the index of this version, the greater the range.

Also pay attention to additional features adapter and its functionality. If you need, for example, a connection with audio devices, headphones or speakers, a prerequisite will be the adapter's support for the A2DP protocol. It is specially designed for audio signal transmission High Quality, but not supported by all adapters.

Features of Bluetooth versions and additional features

With the gradual development and refinement of the Bluetooth protocol, the developer of this technology continues to release newer and better versions. When choosing an adapter, you should definitely pay attention to the protocol version it supports. The higher this value, the more functionality, range and energy efficiency the adapter has.

The maximum version for today has an index of 4.1 and allows you to establish a stable connection with devices located within a radius of 60 meters. This version has the most economical system of energy use, which is very important when connecting to mobile devices running on battery power. Important advantages of the newest versions of Bluetooth are gradually increasing data transfer rates and automatic reconnection of lost connections.

If an adapter is purchased that supports the most current version of the protocol and an appropriate program is installed on a Windows-based PC to communicate with a specific device, the Bluetooth functionality increases significantly, and it can be used for a variety of purposes. The program for connecting with a smartphone or tablet will allow you to wirelessly connect Windows and iOS or Android to transfer photos and access the Internet. A program compatible with your audio system will allow you to play music, control its playback and volume.

If your apartment is equipped with the " smart House", exists special program, which will allow you to adjust the brightness of lighting or remotely turn on various household appliances. The functionality that you will have when using this data transfer technology is limited only by the number of devices in your home or office that support a Bluetooth connection.

How to choose the right adapter

Based on all the information described above, you can draw several conclusions that will help you make the right choice and purchase the Bluetooth adapter that best suits your needs. If you need to equip a stationary PC with support for this protocol, both the internal board and external USB adapter.

Note that the inner version may be more powerful and capable of serving a wider radius than the outer whistle. Please check this point before buying. As for the rest of the parameters, there is not much difference between internal and external solutions. Their design will not affect the Bluetooth configuration process in Windows in any way, nor will they affect the data transfer rate.

Connection and configuration

When the adapter is selected and purchased, it remains to make the necessary Windows settings and a computer in order to enable data transfer, as well as find and connect all the necessary devices. As a rule, regardless of the manufacturer of this PC component, after the first connection or reboot Windows system automatically recognizes the type of a new device, its manufacturer, independently downloads and installs the necessary driver that allows you to turn on Bluetooth. However, this will only allow you to find and connect to your gadgets. Some of them may require you to enter a security pin code to confirm the connection. V bluetooth version 4.1 The default password is "0000" (four zeros). However, after establishing a connection, you will need a program that will allow you to work with the connected device.

The website of the manufacturers of some of these adapters may contain a proprietary program that activates the basic functions of this PC component. To connect to specific gadgets (smartphones and tablets), you may need a program or utility from the manufacturer of the devices themselves in order to use their functionality to the fullest.

For example, to enable contact synchronization between your phone and Windows, you need a software program released by your phone manufacturer. To use on a computer Mobile Internet modem mode accepted by your smartphone or tablet, modified drivers for the PC network card may be required. To clarify all the capabilities of your devices and install specialized software, visit the official websites of the manufacturers.

Outcome

If your computer still does not have a Bluetooth adapter installed, we definitely recommend that you think about buying one. With it, you can get rid of many cables and make it much easier to manage, use and configure many devices already in your office or apartment.

Tell us in the comments what you use Bluetooth for in everyday life and which adapter you have chosen.

The need to install a bluetooth adapter for a computer arises when you need to quickly move information between different devices. For example, between a desktop PC and a mobile phone.

Bluetooth technology provides a fairly high data transfer rate and, unlike Wi-Fi, does not require the use of additional software and server configuration. To connect several devices, it is enough to buy a special adapter, connect it to a computer and configure.

The principle of operation and configuration of the bluetooth adapter for PC

The appearance of most adapters designed for connection to a computer or laptop (on which bluetooth support is also rare) resembles a small USB flash drive. Some are even smaller.

And to amplify the signal on these devices, a small antenna can be installed, adding 2-5 dBi. Built-in bluetooth adapters are cards that connect inside a PC (usually to a PCI slot) and sometimes provide a wireless connection using Wi-Fi technology.

Rice. 1. Options for bluetooth adapters.

Most adapters are installed and configured automatically upon connection. Some require manual configuration. Moreover, to enable them, you even need to go to the device manager menu, find the appropriate item, find out its ID and download the appropriate driver from the network.

Rice. 2. Manual installation drivers for an adapter that was not detected automatically.

BlueTooth technology is based on radio communication and allows two devices to be connected to each other almost invisibly to the user. The advantages of using an adapter include:

• direct connection, even if there are obstacles between devices;
• the ability to install on any PC or laptop with a USB port 2.0 and more modern connector versions;
• a wide range of devices at an affordable price;
• the default presence on most tablets and almost every smartphone.

The disadvantages of the device include a relatively low speed compared to a wireless Wi-Fi connection. In addition, most models transmit data over a short distance. Although when buying an adapter with an amplifier, you can increase the distance to several tens of meters - the result is impressive even for a Wi-Fi adapter.

Device classification

Bluetooth adapters are primarily classified by range:

• older models, class 4, are capable of connecting two devices, the distance between which does not exceed 2–5 meters;
• Class 3 devices provide connections at a distance of 5 to 10 m;

Rice. 3. Standard Bluetooth class 2 modules with a distance of up to 10 m.

• Class 2 adapters allow you to connect if the distance between the computer and another gadget does not exceed 50 m;
• the first class, which printers, modems and base stations are equipped with, makes it possible to transfer data within a radius of 100 m from the adapter.

Using antennas that amplify the signal increases the distance. At the same time, devices of the same class provide connection in different ways in different conditions. Since both the range and the stability of the connection depend not only on the characteristics of the adapter, but also on the configuration of the premises, and on the material of the enclosing structures.

Features of the bluetooth adapter

You can use USB Bluetooth adapters in the following situations:

• to transfer information from mobile device to a computer or vice versa. This opportunity is especially useful in the absence of a data cable for connecting devices and if it is impossible to use Wi-Fi for this (technology that is not supported on older phones);
• for wireless connection of two computers within range of the bluetooth adapter;
• to connect a printer to a computer, digital camera, headphones and other devices.

In most cases, using Bluetooth technology instead of Wi-Fi or cable will increase the distance that connected devices can be. For example, you can connect two computers in this way, even if they are in neighboring rooms and even apartments.

And if you need to transfer data from an old model mobile phone (with a special cord format for connection, like Samsung models or Sony Ericsson), this may be the only option available. The only alternative is to buy a special cord, the cost is higher than that of the adapter.

Features of the choice of adapter

Before choosing a bluetooth adapter for your computer, you should make sure that it is not included in the device package. V stationary computers wireless technology is usually not supported. And to check for Bluetooth on a laptop, you can:

• check for the presence of the corresponding character on the keyboard;

Rice. 5. Keys that allow you to turn on the bluetooth module on the laptop.

• Open the device manager and check for the module. The same option is also suitable for a stationary personal computer, although usually their owners already know about the installed boards and adapters.

After confirming the need to purchase a device, they proceed to its selection, focusing on three main parameters. The first is the protocol supported by the adapter. The second is the range of the device. And, finally, the third is the price due to both the class and the manufacturer, and the protection from external influences.

Selecting the device protocol

The availability of several generations of bluetooth adapters on the market makes it difficult to choose the right model. Moreover, according to the information on the pages of online stores, it is difficult to navigate which device can be considered new and which is already outdated.

Rice. 6. One of the outdated adapter models that can still be found on sale.

It should be noted that the speed of data transfer, and the stability of the connection, and the price depend on the adapter protocol. Latest Versions, 4.1 and above, not only allow you to connect any devices without connection problems, but also provide stable data transmission without interruptions and failures, and even consume less power.

In addition, when you leave the range of the adapter and return to it, the connection is restored automatically. And modern devices can support the connection of several gadgets at the same time.

Range selection

When choosing an adapter, one of the main factors is its range of action. Given that the increase in range is proportional to the increase in the price of the device, it is not necessary to buy a first-class model, the cost of which is noticeably higher. Especially when it comes to home use, where the distance between devices rarely exceeds 10 meters.

For home and small office adapters of class 2 or 3, as a rule, do not have an antenna, and are in the price range up to 200-300 rubles, are suitable. For large premises, it is advisable to choose class 1 models that support the 4.0 and 4.1 protocols - in addition to a range of more than 50 meters, they will also provide a speed of at least 3 Mbit / s. Their cost can reach 1000 rubles.

Modifications to adapters with built-in antennas are even more expensive. Most often, they provide two types of wireless communication at the same time - both Bluetooth and Wi-Fi. Their cost can exceed 2000 rubles, but the functionality is much higher. With the help of such equipment, information will be guaranteed to be transmitted to any device - to a laptop, to a smartphone, and to another computer with a built-in adapter and supporting wireless technology.

Other selection features

In addition to the range and protocol of the BlueTooth adapter, when choosing, attention is paid to such characteristics as:

• type of connection to the computer;
• equipment manufacturer;
• functionality;
• strength;
• price.

The price range is important for those users for whom the data transfer rate and range do not matter. To connect devices located in the same room, any device is sufficient, even with protocol 1.2 or 2.0. When constantly transferring large files and a distance exceeding 10-15 meters, it is advisable not to save money, but to purchase an adapter that supports Bluetooth 4.0 or 4.1 transmission technology.

Durability matters if the device is constantly moved and installed on different computers or laptops. For the same situations, the purchase of a gadget connected to the USB port is required. If the instrument is intended to be used on only one computer, you can select the in-board model. Moreover, such adapters can also provide Wi-Fi.

Popular manufacturers of bluetooth adapters are 3Com, Intel, 4World, Tracer, Broadcom, Atheros and GSM-Support. And among the brands, the assortment of which is represented by budget models, it is worth noting the brands Trust and StLab.

Compatibility of adapters may also depend on the manufacturer - for example, devices from 3Com come with their own drivers, which are not always detected automatically. Although most models from other companies do not even require adjustment.

Popular models

Today in online stores you can find the following Bluetooth adapters:

• among budget options that differ in minimal prices, but also in a low data transfer rate (protocol 2.0): Tekram TM-303, STLab B-122 and CLiPtec ZB626;
• in the middle price range and with support for protocols 4.0 and 4.1: Grand-X BT40G, IOGEAR GBU521 and STLab B-421;

Rice. 8. Model of adapter Grand-X BT40G costing about 600 rubles.

• among the relatively inexpensive models that provide both Bluetooth and Wi-Fi, and connect via a USB 2.0 port: Edimax EW-7611ULB (Wi-Fi up to 150 Mbps, Bluetooth - 3 Mbps).

If necessary, provide both types of wired connection it is worth paying attention to the models Intel 7265NGW.AC, Intel 7260HMW.AN and ASUS PCE-AC55BТ, which support data transfer at speeds up to 867 Mbps for Wi-Fi and up to 3 Mbps for Bluetooth. Devices connect to M2 and PCI-E ports.

conclusions

The use of bluetooth adapters allows you to practically do without a wired connection of devices to each other to transfer information. This not only improves the convenience of sharing files, but also eliminates the need to purchase data cables with different connectors for each individual gadget.

At the same time, the purchase of an adapter does not require either large expenses or a significant investment of time for their adjustment. Automatic detection of the device does not require any action on the part of the user at all. And even with manual update this is unlikely to take more than 10 minutes.

The growth of the possibilities of the digital world leads to the need to exchange information between different devices - computers, smartphones, printers, and other equipment. For this, wired and wireless methods have been developed. The simplest option is bluetooth (Bluetooth - from English - "blue tooth"). This was the nickname in the 10th century for the Viking king Harald I Bluetooth, who united all Danish tribes into a single kingdom. By analogy with it, Bluetooth combines communication protocols different devices into one universal standard.

What is a bluetooth adapter

Bluetooth technology was proposed by the Swedish company Ericsson in 1994 as an alternative to the RS-232 protocol. In 1998, the Bluetooth Special Interest Group (Bluetooth SIG) was created, which included Ericsson, IBM, Intel, Toshiba and Nokia. And since 2002, the Bluetooth specification has been included in the IEEE 802.15.1 standard. For devices that do not incorporate a bluetooth chip at the manufacturing stage, an external device is required. This has become a bluetooth adapter, which must be installed into a USB port - it will provide communication with a mouse, phone, and other devices.

Operating principle

Bluetooth operation carried out on the principles of radio communication in the ISM-range 2.4-2.4835 GHz. The applied FHSS frequency hopping method according to the pseudo-random algorithm, known only to the transmitter and receiver, changes the carrier frequency of the signal 1600 times per second, choosing from 79 operating frequencies. This and additional coding of digital data or audio signal protects the confidentiality of information transmission. Possible loss of data packets when signals from different transmitters are overlapped is compensated for by duplication of information transmission.

Customization

Most computers determine the type of bluetooth connector, connect and configure it automatically after installing it into the USB connector. If the computer does not see the connected adapter, you need to do the following:

• if an installation disc with drivers is supplied with the adapter, you must connect the adapter and start the disc - the process of searching and installing adapter drivers should be done automatically or following the instructions of the installer;
• Without installation disk by the manufacturer's brand and full name, you must download the driver for this device from the Internet;
• then you need to find the Bluetooth adapter in the Device Manager and, by right-clicking on its icon, go to Properties-> Driver-> Update driver;
• select the downloaded driver for your bluetooth adapter on your computer;
• this device is connected.

Bluetooth adapter for computer

The gradation of these devices in terms of quality, power and range occurs by classes. Bluetooth technology is simpler than WiFi, does not require additional network modules, adapters, and is constantly being improved. AIRcable in 2007 created the Host XR device with the ability to connect two antennas, one of which operates at a distance of up to 1 km, the other - with a range of up to 30 km. The most common classes of household adapters on sale and their characteristics are presented in the table:

Video

Modern communication technologies, in particular the bluetooth adapter (module), will significantly improve us to do a number of activities.

Today there is no problem to transfer files from computer to mobile phone and vice versa.

Thanks to Bluetooth device it gets simple and fast. How to choose the right bluetooth for your computer? Below I will try to answer this question.

How to choose a bluetooth adapter for your computer

Bluetooth is a short-range wireless technology. It occurs between various electronic devices, including a keyboard, computer, laptop, PDA or mobile phone.

Bluetooth technology can be used if a Bluetooth adapter (module) is installed. If you want to buy it, you will have to choose from a huge range of different devices.

A modern Bluetooth adapter can be easily connected to a computer via USB 2.0. It can be purchased from electronics stores or home appliances supermarkets.

Needless to say, purchasing it gives you more options for transferring data to external devices.

When buying a bluetooth module (adapter), you should pay attention to its range. It must be at least 10 meters long.

In open space, the distance is greater. In modern adapters of this type, it is up to 100 meters.

In general, adapters have a range of several classes. If yours is in class 3, then it works at a distance of 10 meters.

This class, has bluetooth in the PDA, mobile phones and peripherals to computers.

The third class is more than enough to connect various devices that are in the same room.

On the other hand, a class 2 community has much more energy and operates in the 20 to 50 meter range.

The strongest modules are included in the first class, where you can work up to 100 meters away.

Such modules are equipped with modems, base stations and printers, as well as some adapters.

• If you do not know how to turn on after the selection, then

The operating range of a Bluetooth adapter is different even when it comes to equipment of the same class.

This is due to the use of various components, the way of implementation, as well as the way of connecting the antenna and the quality of the antenna itself.

The materials used to make the walls of the room in which you use Bluetooth are also significant.

With the help of bluetooth, you can send small data without the need to use a cable for this purpose.

It should be noted that these devices consume very little power, but their disadvantage is that they have a low data transfer rate.

When deciding on a specific bluetooth device, you should look to ensure that the device has its own MAC address. If not, then you may have to deal with restrictions in the future.

V computer bluetooth can perform many different functions. Not only can it transfer files from your computer, but it will also allow you to access your local computer network and sync messages from other devices that support this function.

In addition, thanks to Bluetooth`owi, you can use a printer, wireless keyboard, mouse, joystick, or download photos from a digital camera to your computer.

There are headphones, microphones and loudspeakers on the market that work by combining a computer with a bluetooth device.

When buying, the profile of the standalone device is important, which determines which one you will be able to use it, for example, a driver.

Even adapters with exactly the same structure can have a completely different set of functions.

Therefore, in the case of a computer, pay attention to operating system... The reason is that Linux does not yet have built-in Bluetooth support.

Several manufacturers, including 3Com, have developed their own drivers.

The vast majority of USB adapters are equipped with Widcomm drivers, which are capable of handling almost all kinds of devices.

However, many devices, unfortunately, have old version Widcomm, which is not without errors, and some manufacturers do not allow updating it due to the high cost of such an operation.
