History of the Wi-Fi IEEE 802.11 wireless standard.
Back then, Bluetooth was seen as simply a cable replacement, not a real network system like Wi-Fi. The main concern was whether the coexistence of both wireless protocols would lead to destructive interference potentially crippling both technologies. This issue of interference between Bluetooth and Wi-Fi signals was so important that the IEEE standards body even had an “802 Coexistence Study Group,” chaired by Jim Lansford, VP of Business Development for Mobilian (acquired by Intel), back in 2001. Today, Lansford is the director of technical standards at Qualcomm, where coexistence issues have expanded far beyond just Bluetooth and Wi-Fi.
