Change in Wi-Fi Calling Not Dropping Calls When Leaving Wireless Hotspot Location -- Huge Improvement!

Like many of you, I use my cell phone all the time. I use it for browsing the web, social media, email, calendar, and to stay updated on news. For a few years now, I have relied upon Wi-Fi Calling to be enabled so that if there was a wireless connection available to which I was connected, I could rely on that connection to make and receive calls. Without this option, it was not possible in some places to make or receive calls let alone to be able to interact on the internet. Today, there is almost no where that I go that a internet connection is not available. 

When I first started using Wi-Fi calling on my phone, I found that if I was in say my office and on a call with my cell, if I left the building, the call would drop. The call was attempting to transition from the internet connection to the towers. I had really not tried to walk away from a connection for at least the past two years until recently. I was surprised to find that my call did not drop. I did further testing to see if I was on a call and went into an area with wireless would it drop as it handed the call from the cell tower to the wireless access point... Sure enough, this worked too and worked smoothly. 

Much improved process with the hand-off to and from Wi-Fi calling on the iPhone. I know there were many times I would call Carrie to let her know I was heading to pick her up for lunch and as I walked to my car, the call would drop. Now, that is not an issue as I can get to the car, drive out of the lot, and the call never drops. 

I am not sure if this was an improvement by the standards for mobile phones, an Apple change, or something that was improved with the hand-off between my device and either Wi-Fi or tower. Whatever it is, I am thankful for the improvement. I rely on my phone heavily and knowing that I can leave a place that has Wi-Fi and the call will not drop is important.

While it is not ideal to drop a call to my wife, it can be awkward to drop a call to a vendor, or customer, as I leave the office. Left calling them back saying "sorry, I am not sure what happened to the connection" where the whole time I know it was because I had left a place with wireless where I had placed the call and now I am in an area without wireless. This is no longer a concern as it works the way I would hope it would work.

Again, I am not sure when this changed as I could not find much information about it. I am not sure if this is an improvement only for iPhones or if Android also benefits off of this change. If it is all phones, then I wonder if this was an improvement that was made by the FCC to be able to hand the call between no Wi-Fi and connected to Wi-Fi.
