Wildly varying LTE speeds between carriers in one spot provide a useful reminder: "LTE" can mean many things.
If you use AT&T and need to download some huge files, head over to Arlington's Courthouse neighborhood. At the farmers market there this morning, Speedtest.net's Android app clocked the carrier's LTE downloads at 45 to 48 million bits per second, with uploads running at around 12 Mbps.
That is absolutely bonkers.
Then I tried a Sprint phone--this being one of the few places where its D.C.-area LTE service is up--and saw much worse results. With three bars of LTE signal, Speedtest's Windows Phone app reported 3 to 7 Mbps downloads; with four, 11 and just under 14 Mbps.
(My non-LTE phone routinely exceeds 12 Mbps on T-Mobile's HSPA+ service, and I've seen Verizon LTE phones get from 12 to 20.)
So, no, you shouldn't place too much emphasis on "LTE" alone as a selling point.
