I did not know that. For my previous job used to have to make a semi regular visit to the 13th (I think) floor of the VA where there was a bunch of construction going on. I must have been way above sea level. And contrary to that, I also used to have to go to sub basement #2 of HSBC Tower. The only form of communication that worked down there at the time (2010 - 2013) was 2 way radio.
I can only speak for T-Mobile, but generally in the Buffalo area, outdoors, with a stronger signal Download can be 80 – 100 Mbps, Upload can be 15 – 20 Mbps. Indoors it drops, and drops quick.
Very rarely do I go downtown or anywhere close to the city now that I'm not required to for work. However on the 15th I went to Key Bank Center for Trans-Siberian Orchestra. Outside of the arena while waiting to be let it I was getting 90 – 110 down and a solid 20 up. Inside, on the floor sitting where center ice would be, right underneath the Jumbotron, my speeds were cut in half. Topped out at around 50 x 10.
Just got back from burning some Christmas gift cards before all of the drunks get on the road.
Cheektowaga – In line at Chick Fil A – 30 x 15
Williamsville – Hobby Lobby parking lot – 90 x 15 / inside Hobby Lobby – 60 x 10
Williamsville – Wegman’s parking lot – 95 x 15 / Wegman’s café second story – 45 x 10
Depew – future site of Chick Fil A #2 – 135 x 25
Lancaster – ATM at bank near D&L Plaza - 120 x 15
And these are from Eastern Hills. The 191 is from right by Lenco Lumber, 187 is near the back of the mall by the movie theater entrance. The difference in upload is very surprising to me. Pings are always inbetween 50 - 70 ms. When I had Sprint, I'd get pings in the 40s, Verizon was 30s and 40s. In the Spring when I went to NYC and Long Island, T-Mobile pings were in the 30s, so I know they are capable of it, just don't see it around here.
Out in my neck of the woods aka God's Country in rural Eastern Erie/Northern Wyoming/Southern Genesee, if I actually have service, I can usually do 120 x 20 with no problem when near a tower.
