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.

Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization. Bluetooth can, and often does, interfere with 2.4GHz Wi-Fi channels, however the adaptive frequency hopping feature can minimize disruptions to Wi-Fi.

藍牙(英語:Bluetooth),一種无线通讯技術標準,用來讓固定與行動裝置,在短距離間交換資料,以形成個人區域網絡(PAN)。其使用短波特高頻(UHF)無線電波,經由2.4至2.485 GHz的ISM頻段來進行通信。1994年由電信商愛立信(Ericsson)發展出這個技術。它最初的設計是希望建立一個RS-232數據線的無線通訊替代版本。它能夠連結多個裝置,以克服同步的問題。 藍牙技術目前由藍牙技術聯盟(SIG)來負責維護其技術標準,其成員已超過三万,分布在電信、電腦、網路與消費性電子產品等领域。IEEE曾經將藍牙技術標準化為IEEE 802.15.1,但是這個標準已經不再繼續使用。
