In recent years, Bluetooth has been regarded as a comfortable way of connection of different devices. One of its favorite applications has been wireless streaming of musing files from a computer, smartphone or a tablet to a speaker. However, despite its extensive use, due to its limitations in distance, this feature has had its own setbacks. Up until recently, Bluetooth had a maximum range of about 30M, and if there were walls present in its way, it had a lesser usable distance.
There are different Bluetooth devices and one of the most commonly used standards for the classification of Bluetooth devices is the followings
Class 1: refers to devices up to 100-meter range (normally 20-30m)
Class f: refers to devices up to 30-meter range (normally 5-10m)
It should be mentioned that other than the choice of the transmitter, the range also depends on the mobile phone that receives the signals. Also, other involved parameters for the proper reception of Bluetooth signals include atmospheric, urban conditions. At higher ranges, the transmission speed gets slower.
For most of the bluetooth speaker the Transfer distance within 10m, one of which is introduced below.
