Qualcomm and Internet giants call for clear coexistence rules in 60 GHz

Despite the hype around 5G millimeter wave bands such as 26/28 GHz, much of the pioneering work of making high frequency spectrum economically viable for mainstream wireless devices was done in 60 GHz. In most regions, this is unlicensed spectrum in which the dominant technology has been the WiFi-like technology WiGig (IEEE 802.11ad standard, with a next generation planned, called 802.11ay). However, even in a band with plentiful capacity and a relatively mature technology, there can still be disputes about who should be able to use it, and how to protect others from interference. A group of companies including Qualcomm, Facebook, Google, Intel and Samsung have formed a 60 GHz Coexistence Study Group because they are concerned about the use…
