Yes, technology never stays the same. The ground under you keeps changing and this is true for things like wifi, 4G LTE and so on.

For the past several months, when it comes to mobile, Dr. Z has made video calls using LTE and it is a much more reliable thing than wifi. The scenario was different over a year ago when wifi seemed the way to go–until LTE coverage got better.

But, we have to think of a few things: there is usually a limit (or cap) on LTE usage. So, when making LTE calls via Z5 or Facetime, you have to keep an eye on data usage. With wifi, this is not an issue, but with wifi, the signals can be unreliable or too low for video communication. If you do a speedtest with wifi and it’s good, then go for it. But if the wifi signal is too low for video communication, then LTE is the way to go. Be mindful that if you have an iPad without LTE, you are pretty much limited to wifi.

In the home, wifi signals are usually much better, so using an iPad in the home, you should be in pretty good shape. The situation is different when using iPad in public wifi areas.

In public, using an iPhone is usually better for video communication.

Basically, a blue hard-wired ethernet connection is usually the best, but they usually cannot be connected to mobile devices.

This situation may change in the next six months–we never know, with the way technology bounces.

By the way, if you need video communication (VP or VRS), why not try Z5, you will like it! Click here to get it! (See if you qualify to get a FREE tablet with a stand!)
