Valid question.  Once the operators start using the UNII band, whether for Wi-Fi or LTE-U, will the airlink get too crowded for private networks?  Eventually, I would guess - yes, but not for a while.  The UNII band is for all to share.

Are we changing the purpose of WiFi?

The purpose of WiFi, from the start, was to offer consumers a wireless network option to use in homes, or for businesses to use on their premises, to avoid having to deploy numerous wired Ethernet access points. So, I view WiFi as being a scheme that needs to remain localized, in order to continue meeting that original design mission.

Of course, one can certainly take the radio part of WiFi, add to it the roaming and handover techniques used in cellular (techniques which are really independent of the "radio layer" anyway), and create a cellular system out of WiFi. I don't see anything dramatically difficult in this, except for what it might mean to the original purpose of 802.11.

So for example, if I live in an area which is covered by a cellular WiFi network, presumably at high enough power that it propagates indside my home or office, does this mean that I won't have access to the already limited WiFi RF channels? Or do people assume that with this cellular WiFi concept, no one would "need" to deploy their own wireless net? Or will additional frequencies be made available for this new cellular role, so as not to detract from previous uses of the scheme? There are very valid reasons why people and businesses would want to retain their own networks, in case that needs to be discussed.
