Buying Guide to Bluetooth Range Extenders
If Bluetooth 3 promised a huge increase speed, Bluetooth 4 comes with an improvement that will allow the widening spectrum of functionality for this technology: very low power consumption.
For mobile phones, will not be a major impact. In fact, GPS and Wi-Fi or GPS receiver consumes more power than ordinary Bluetooth used occasionally for several minutes. Instead, technology can be successfully used in various medical devices that require a functioning health care facilities continues, thanks to reduced energy consumption. In addition, the technology will be implemented including electronic devices such as watches and TV remotes.
The range will also increase significantly. On Bluetooth 2, two telephones can be connected at a distance of about 10 meters, possibly up to 30 meters, depending on the nature of interference. In contrast, 4 will have a Bluetooth range of up to 60 meters, which will facilitate device connectivity.
Increased compatibility between terminals
Finally, Bluetooth 4 promises better compatibility between mobile phones. It is known that often file transfers between phones of different companies products are either impossible or discontinued without a logical explanation, even if the technology used is the same. This kind of incompatibility will vanish once the new version, a good enough reason to be adopted.
If one of the two devices does not have WiFi then the transfer will take place more slowly through Bluetooth. The WiFi Speed Transfer will be around 24 Mbps, which is about 2-3 MB / s real.
Of course, to take advantage of these features, both devices must be equipped with Bluetooth version 3.0.
Bluetooth 3.0 HS (High Speed) is the official name for devices that also support the WiFi quick transfer function. On Bluetooth 3 you can enjoy:
Enhanced Power Control – function that will automatically control the transmission and reception power, decreasing the number of disconnections.
Generic Alternate MAC / PHY (AMP) – site pairing (pairing of two Bluetooth devices) is done via Bluetooth and transfer files if WiFi is much faster.
Bluetooth technology has become the most popular wireless solution for a growing market for devices like mobile phones, digital cameras and video cameras, computers, PDAs, printers, etc..
It is a step forward for small networks due to technological advantages that allow operation without user intervention and at a very low power consumption, thus making it suitable to be used by small devices, portables, which are usually battery-powered .
The Bluetooth technology in RF communication is being used a 2.4-gigahertz frequency band (ie between 2.402 GHz and 2.480 GHz) that requires no license and thus can be used almost anywhere. The tape is divided into 79 radio channels, each channel having a bandwidth of 1 MHz.
Radio interference to be properly treated because the operating bandwidth and other communication technologies like radio frequency cordless phones, automatic garage doors, etc.. Bluetooth technology uses the change in the scattering spectrum frequency hopping, the frequency change is occurring 1600 times per second. Each device has a wide choice of 79 frequencies that change 1600 times a second, it is unlikely that two devices are on the same frequency at the same time, and if interference occurs, however, it takes only a small fraction of a second.
When two Bluetooth devices establish a connection, one working in the role as master and one slave, with the possibility that any device to function as a master and the slave connected to another link. In a master can be connected up to 7 active slave sites, or still 255 slave sites if they are in park mode, the network is called piconet. The role of master of a device does not give any privileges or authority, is responsible for synchronizing master devices connected to it.
The distance between the two devices can establish a communication channel depends on the power class. The table below shows the three classes of power and connection specific maximum distance each.
Power Class Range allowed
Class 1 max. 100 mW (20 dBm) approx. 100 meters
Class 2 max. 2.5 mW (4 dBm) approx. 10 meters
Class 3 max. 1 mW (0 dBm) approx. 1 meter
Bluetooth is a set of specifications based on radio waves to a wireless network (PAN – Personal Area Network). Bluetooth creates a path by which to exchange information between devices such as mobile phones, laptops, personal computers, printers, digital cameras and video consoles through a secure radio frequency and short range.
Bluetooth devices communicate with each other when they are in the same range. They use a radio communications system so that it need not to be aligned to deliver face to face, can be in different rooms if the transmission is strong enough.
Bluetooth specification was first formulated by Sven Mattisson and Jaap Haartsen, workers in Lund, Sweden, Ericsson’s mobile division. On 20 May 1998 group was founded Bluetooth Special Interest Group (SIG) which now has the role of Bluetooth technology firms bid to trace the evolution of this technology.
Why is it called Bluetooth? Viking king Harald Bluetooth united Norway and Denmark, he was renowned as being very communicative and it was good to make people communicate with each other – but never would have thought that a thousand years later, the performance technology will be named with his name!
Bluetooth 1.0 and 1.0b
Versions 1.0 and 1.0b had many problems that made large producers struggling to meet their functional products.
- Many of the errors found have been repaired in version 1.0b
- Support for unencrypted channels
- The added signal strength indicator of transmission
This version is compatible with 1.1.
- Practical speed data transmission has been increased to 721 kbps, as in version 1.1
This version is compatible with version 1.x. Home improvement is the introduction of higher transmission speeds called Enhanced Data Rate, which allows a speed of 3.2 mbps. Improvement has created the following effects:
- Transmission speed three times higher
- Less power consumption,
- Transmission error rate (BER – bit error rate) lower.
