Hello, community! First-time poster here, and relatively new to “professional” 4G/LTE/5G hardware and services.
We have a new mobile coach that will be roaming all over Ohio starting January. I’m one of the IT System Admins here at the college and have been performing onboard network testing between PCs/Laptops onboard to our campus servers via VPN. So far, we’re pretty disappointed with our simulated, real-world testing with various data-transfer methods (about 10-25Mbps Up, 60Mbps Down). Our biggest concern is when it’s going around to more rural areas in Ohio where it gets worse.
We currently have (2) T-Mobile, (1) AT&T and (1) Verizon 5G cards along with a Starlink on WAN2. Our coach is currently parked at one of our offices in a large, metropolitan city with mixed signal/service results. So far, T-Mobile seems the strongest connecting at mostly full-bars on 5G, but the others vary with some only connecting at 4G/LTE.
First, we’re wondering if mixing 4G/LTE and 5G connection can slow the overall throughput performance.
Second, should we force only 5G connections with, say 3 bars or more on all 4 Cellular devices?
Or, just leave everything at the defaults and the device will take care of everything?
And finally, I’m reading about T-Mobile’s Band 71. Should we replace the AT&T and Verizon with more T-Mobile SIM cards?
I welcome any configuration recommendations you might have based on your experience.
Thanks in advance!
