New York City- NPERF (Part 1)

Keith Calligan -

********

I updated this article due to the fact that I had forgotten that video streaming was limited to a lower resolution on Verizon and ATT phones.  My previous results in regards to NPERF test were not accurate in that regard.  I have fixed for later tests.  I also removed the average total score because this is heavily weighted on streaming tests.  I adjusted my conclusion to show that Verizon was the best in all but browsing test and maximum speed.

Yesterday, I made a trip on the NJ transit from the Hamilton, NJ area to New York City.  The test phones were brought with me but I didn't have easy access to them during the day (just the automated G-Nettrack Pro running on them).  The plan is to plot those results shortly but in the meantime, I ran some Nperf tests on the my Iphone (all 3 carriers) and exported those results to a CSV file.  The information contained here is from walking around New York City (Penn station to Time Square area) and back.
