I really wish Wifi to 4g handoff was truly seamless since that's a lot of the reason I end up turning wifi off. As I'm walking around an office building or a college campus, loading webpages is a subpar experience at best since it's constantly losing wifi, switching to 4g, and re-establishing all of my connections. I have the same issue with sticky wifi connections where my phone stays connected for 10-20 seconds after I am out of range of the network, during which nothing works. I would love to either have a vpn that connects over 4g and wifi and seamlessly redirects traffic depending on conditions, or have widespread support for something like multipath-tcp that supposedly fixes this issue.

1. WiFi, even the current 802.11ac were never designed for those usage. It was for a few people in small area using it lightly, not constantly. 2. WiFi / Unlicensed Spectrum has limited power compared to licensed Spectrum. Which means full coverage is few order of magnitude harder. 3. I still think weak signal and hand off is an software and implementation issues. We should just disconnect WiFi if its signal is only 2 bars and not try to do edge location transfer. The upcoming 802.11ax fixes that somewhat, and it should be able to handle 32+ concurrent users, and with up 8x8 antenna in phase 1 ( Not confirmed yet ) and hopefully 16x16 in phase 2. I am not sure if Phase 1 and Phase 2 are compatible in such a way so Phase 2 router would benefits Phase 1 users as well. After-all these manufacture are there to make you spend more money to upgrade. Another problem is all these are good on paper, but once 802.11ax are mixed with 802.11ac, its performance and capacity drops dramatically. So I actually wish in the far future we force more users on ax, drop ac from 5Ghz band and users uses N on the 2.4Ghz band. Or better yet, LAA, ( License Assisted Access ). While technically superior I am not entirely comfortable of putting everything in carrier's hand. And Full LTE in Unlicensed Spectrum; MulteFire, is an entirely Qualcomm tech.
