Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was initially conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming synchronization problems.

Bluetooth can, and often does, interfere with 2.4GHz Wi-Fi channels, however the adaptive frequency hopping feature can minimize disruptions to Wi-Fi.

Bluetooth (wym. /ˈblu:tu:θ)/ – standard bezprzewodowej komunikacji krótkiego zasięgu pomiędzy różnymi urządzeniami elektronicznymi, takimi jak klawiatura, komputer, laptop, palmtop, smartfon i wieloma innymi. Jest to otwarty standard opisany w specyfikacji IEEE 802.15.1. Jego specyfikacja techniczna obejmuje trzy klasy mocy nadawczej ERP 1-3 o zasięgu 100, 10 oraz 1 metra w otwartej przestrzeni. Najczęściej spotykaną klasą jest klasa druga. Standard korzysta z fal radiowych w paśmie częstotliwości ISM 2,4 GHz. Urządzenie umożliwiające wykorzystanie tego standardu to adapter Bluetooth. Bluetooth zawiera patenty, z których można korzystać bezpłatnie w produktach zakwalifikowanych jako zgodne z Bluetooth. Kwalifikacja kosztuje 5–10 tys. USD, za to potencjalni klienci-użytkownicy mogą łatwo znaleźć nowy produkt na opublikowanej w tym celu liście.
