My 4G RBI connection sometimes varies a lot. Right now it has absolutely plummeted. At the moment I mainly attribute this to the weather, as we have been under a constant rain dump for the last two days. Today has been the worst I have ever experienced, less than 1 Mbps down and pings as much as nearly 400 ms (usually around 50-60 ms).
It occurred to me that 3G might do better under these conditions so I decided to give it a try. It didn't really seem to make much difference but it did make me wonder about something. On the Huawei there are only three network settings, LTE Preferred, 4G, and 3G. I understand 3G but I wonder what the difference is between LTE Preferred and 4G. I have two antennas but they are not in LTE configuration. Both are vertically oriented, pointed the same way. When I set them up this gave me the best result. When I tilted the antennas at 45 degrees my speeds dropped regardless of how I positioned them.
So what difference does the Huawei see between LTE and 4G?
