Revisit 8/9/21 - 8/12/21 Maryland

Verizon

I would put Verizon as best in regards to signal level for this analysis but the worst in regards to RSRQ.  This is most likely due to congestion.

Disregard the area that shows all orange (RSRQ) and all blue (RSRP) in Bel, Air MD area (24 and 95) to Conowingo Dam area.  This is most likely some issue with the measurements in that area.

All three carriers showed some issues on Delaware Memorial Bridge.  This was most likely due to congestion and/or switching between a lot of cells since this area has a good line-of-site view to the whole area.  I see similar problems on other high bridges.

AT&T

AT&T was a little worse than Verizon in regards to RSRP/level but held up better in regards to quality.  From a signal/RSRP perspective, I would say AT&T was fairly weak around the Bel Air, MD area.

T-Mobile

T-Mobile was best overall in RSRQ/quality through the whole trip.  They did very well in Northeast MD area (all the way to Aberdeen/Route 22). Even the Cherry Hill area on NJ turnpike to just North of Delaware Memorial Bridge was good.

I would say they were equal in signal level with AT&T (Verizon was best in strength).
