What is Bluetooth (please read this section if you don't have an idea):
Briefly, Bluetooth as a standard for the short-range wireless interconnection. Bluetooth headsets do not work like a wireless phone! It meant to be
short distance
with
direct visual connection
. The 2.4-GHz band used by Bluetooth is 83-MHz wide, which gives a Bluetooth device the ability to hop between 79 different 1-MHz channels within that band. When Bluetooth detects interference on one channel, it can hop to another channel to try to avoid the interference. During this hop, the signal may be degraded or temporarily blocked, depending on what kind of connection the Bluetooth device relies on. In the case of voice services, like a Bluetooth headset, the disruption could cut out your sound when data packets are lost in the midst of a hop. When you encounter cut in and cut out, look for signal
obstacle
first.
Short distance
means 10 yards or less for connection and maybe 5 yards or less for streaming music and/or voice.
Direct visual connection
means your Bluetooth headset (s) should be able to "look" at your cellphone or Bluetooth usb adapter "directly" without any
obstacle
in between of them.
Obstacle
means anything solid which is made by concrete, metal, wood, Plastic, rubber or even a person.
