Well it’s funny you mention that, because since then, I’ve changed my product to use traditional 4G LTE instead of LTE-M. I have had customers in several states have poor experiences with LTE-M including one in Ft.Lauderdale, which is a big city! About 30 minutes south of Austin I had 1 unit on 4G LTE and one on LTE-M and the LTE-M unit was struggling, while the 4G LTE unit was perfectly fine. It’s not Hologram’s fault, it just really sucks that LTE-M just isn’t rolled out like it should be.
One cool thing about Hologram is that in the Dashboard I could see which tower each unit was connected to, and the 4G LTE unit’s tower was very close. So I looked out my car window and saw it in the distance! The LTE-M unit’s tower was miles away, so it’s connection was very spotty, and proved to me that LTE-M is not rolled out on all towers. I’m pretty sure both were on AT&T. I’m done with LTE-M.
