Do We Still Need Wi-Fi in the 6G Era

For more than twenty years, 802.11 or Wi-Fi has been the undisputed champion of enterprise and home networks. Even as fast cellular data networks have become widely available, Wi-Fi still carries the lion’s share of data and has relegated other WLAN or short-range wireless standards to niche roles. But the cellular and Wi-Fi worlds have been converging, slowly, at all layers. Both cellular and Wi-Fi now have commonalities at the physical, network, access control (DIAMETER) and application layers (e.g., web and VoIP) and there’s strong interest in using 5G systems for some high-end applications. In planning for 6G, what lessons can we learn from this parallel existence and the historical developments of these networks? What are the advantages and disadvantages of such a hypothetical convergence?
