Under the ISM band rules defined in FCC Part 15.247, this frequency band is free of tariffs.11 It is license exempt in Europe. However, systems must operate under certain constraints that are supposed to enable multiple systems to coexist in time and place.
Bluetooth and Wi-Fi Interference Cases
If Bluetooth and Wi-Fi operate at the same time in the same place, they will interfere (collide) with each other. Specifically, these systems transmit on overlapping frequencies, creating in-band colored noise for one another. The sidebands of each transmission must also be accounted for. Interference between Bluetooth and Wi-Fi occurs when either of the following is true:
  • An Wi-Fi receiver senses a Bluetooth signal at the same time a Wi-Fi signal is being sent to it. The effect is most pronounced when the Bluetooth signal is within the 22-MHz-wide passband of the Wi-Fi receiver.
  • A Bluetooth receiver senses a Wi-Fi signal at the same time a Bluetooth signal is being sent to it; the effect is most pronounced when the Wi-Fi signal is within the passband of the Bluetooth receiver.
It is worthwhile to note that neither Bluetooth nor Wi-Fi was designed with specific mechanisms to combat the interference that each creates for the other. As a fast frequency-hopping system, Bluetooth assumes that it will hop away from bad channels, minimizing its exposure to interference. The Wi-Fi MAC layer, which is based on the Ethernet protocol, assumes that many stations share the same medium, and therefore, if a transmission fails, it is because two Wi-Fi stations tried to transmit at the same time. Later, this article examines how this assumption drives system behavior that actually worsens the impact of Bluetooth interference.
Nu stiu cum puteti spune ca nu interfera unele cu altele, totusi, afirmatii din neant trebuie sa aiba macar o explicatie...


Si ca o alta rezolvare am gasit ca ar trebui schimbat canalul pe care emite router-ul sau access point-ul, eu mi l-am setat pe 11.

P.S. :

Wi-Fi uses the same radio frequencies as Bluetooth, but with higher power, resulting in a stronger connection. Wi-Fi is sometimes called "wireless Ethernet." This description is accurate, as it also provides an indication of its relative strengths and weaknesses. Wi-Fi requires more setup but is better suited for operating full-scale networks; it enables a faster connection, better range from the base station, and better security than Bluetooth.
