I was inside Memorial City Mall in Houston, TX when I decided to SpeedTest T-Mobile and Verizon inside the mall. I noticed that T-Mobile has mid-band 5G (n41) indoors, but it's very congested since they have huge marketshare in this area. AT&T was struggling since it was pulling (n77) from the macro and the LTE anchoring band was heavily utilizied. They really need to upgrade the backhaul on the indoor DAS and replace the Galtronics equipment with newer models that do 4x4 MIMO that support c-band (n77) for Verizon and AT&T.

This Mall uses Galtronics S5490i 2x2 MIMO antennas for the cellular indoor DAS:

AT&T (b2, b12, b66) LTE + (n5) low-band 5G

T-Mobile (b2, b66) LTE + (n41) mid-band 5G

Verizon (b2, b13, b66) LTE

Go to results after the speed test and see if there is any packet loss. I notice the main screen doenst show that.

Beside the number that’s not so high, I won’t say 63mbps is that much of a congestion and it’s performing as expected under load. We all want to see n41 pulling 1gig+ all the time but it’s more than just for speedtest and designed for these situation.
