The Bluetooth transmits data in low radio frequency. The frequency it transmit the data is on 2.45 GHz. The international agreement has set a side to make use of this radio frequency for medical gadgets and industrial use.
Most of the devices use this radio frequency band for their advantage. Within the range of ISM band there are others also use this band. The mobile phone made for next generation, baby monitors and even to operate the garage doors this radio band frequency are used. In all this the Bluetooth technology operation and transmitting of data is so different that it is design in such a way the interpretation between the Bluetooth and other devices does not occur.
Bluetooth device has the capacity of sending signal as low as 1 mv. By this way the device can avoid in getting interfering with signal derived from other electronic devices. A cell phone transmits signals in the range of 3 watt.
The power signal that comes from the Bluetooth device is within 32 feet. This short range enables chances of non-interference of signals between electronic devices and computer. A direct line sight is not required for the Bluetooth even its signal power is low. The walls have no capability of stopping any signal generated by these devices and this is an advantage for the computer and other devices to operative without any blockage of signals.
Bluetooth device can communicate with 8 other devices simultaneously and at a certain radius but no interference will occur to any of these devices. It uses the low frequency technique. This technique enables other devices not to interfere on such frequency and the transmission rate is high.
Within a designated distance a number of about 79 persons can randomly use the frequencies and also can change from one to another on a certain basis.
The transmission frequency will change 1600 times or more for every second. This enables some more gadgets to make use of the spectrum of the radio waves. Every Bluetooth spread spectrum without any manual operation, hence transmitters on a certain frequency to one gadget to another with not make any change.
When Bluetooth devices share an exchange of data they try to recognize one another. This electronic share of messages between each other will enable other to find out the requirement, and share the wanted data if both devices transmit the signal of acceptance. This transfer of data is done automatically and the user does not have to do a manual operation in this regard.
On completion of acceptance by the two devices, Bluetooth device will make a Personal Area Network or PAN, or piconet that will enable the two gadgets to function. Once this is established by piconet the data transmission will take place between the two gadgets without interruption. Bluetooth technology transmission of date at low frequency enables it data to transfer to another connected gadget without interference is a great boon to the user of computer, cell phone, MP3. Etc.
