Are Wi-Fi and Five-G converging? Wireless internet access has its data-use volume dominated by Wi-Fi in unlicensed spectra. Predominately, unlicensed-spectra use empowers over-the-top applications and their service from any of the billion(s) of locations that terminate wireline internet service in a Wi-Fi access point. Contention protocols attempt to arbitrate Wi-Fi spectrum use, while LTE/5G systems instead leverage licensed cellular infrastructure to plan real-time use to avoid contention. 5G systems sometimes may also be permitted to operate opportunistically in unlicensed spectra in addition to their nominal licensed-spectra operation. This talk provides some insights on how they can converge productively.
