Frans, Unfortunately LTE is a 3GPP protocol (proprietary and designed for efficiency of spectrum usage) and 802.11 is an IEEE protocol (general public, sloppy is accepted ;-). I recently attended a conference on Wi-Fi organized by commercial providers. Most of the presentations were about “how to capitalize Wi-Fi”, not just Wi-Fi-offload, but cash loading with Wi-Fi. I get it, they have to make money, it’s their first duty to their shareholders … but I like my “wireless freedom” and I’ll fight for it. When I switch from cellular to Wi-Fi I feel more relaxed as far as what I can do. I can watch a video online without having to worry about my monthly quota. Also, the sharing of Wi-Fi (visitor access) is decided by the local people who operate it. So, it is not so much about interferences and efficiency but rather about an insidious invasion of a spectrum that is available for the people not for mega large operators.
LTE moving in 5 GHz feels like Wal-Mart moving in a local Farmers Market! They might even sell the same tomatoes grown by the same local people, but the small guys do not decide how it’s done. One day T-Mobile will knock on your door and propose to operate your wireless network with LTE only. (Our University used to have its own bakery and people loved it…then Aramark moved in ;-). Some schools like this model, some don’t. We need to make sure that the choice stays available.
