Here the relays do not work very well since it requires both the available signal to amplify and leak into the building and carrier participation. I really believe that small cell technology is the answer for the foreseeable future since to properly handle Wi-Fi calling requires a voice-grade Wi-Fi network and plenty of internet bandwidth. Obviously small cells do require internet bandwidth or leased lines back to carrier but still I don’t have to optimize my Wi-Fi for every single issue that a phone might bring. My Wi-Fi network was designed for data not voice and it will take a redesign and a large amount of additional access points to put off voice-grade specs.

They are doing cellular relay systems now that work with repeaters to extend coverage from the roof into the core of a building, but the carriers don't seem really excited about that either. They are willing to go along with it, since it requires little on their part other than certifying your design. Minimum cost is probably around $15-20K and goes up as you want to cover larger areas within your building. Works with all carriers and all frequency bands since it's just re-broadcasting the spectrum. I think WiFi calling is probably where this is headed though, with some of the lower quality carriers already enabling this "feature" to offload traffic from their networks. I'd focus your time on having an excellent WiFi network with the type of coverage needed for flawless roaming between APs.
