Hey there guys. I'm new to Sprint and work downtown near Wall Street.
Just started using my new iPhone 6, and was horrified at how bad the "Spark LTE" performance was in the Financial District.
First, I checked to make sure I was on Band 41, and Fieldtest confirmed that indeed I was, with 20 MHz of juicy bandwidth (I wanted to post a screenshot but I cannot figure out how). It says I'm on Band 41, with a DL freq of 39991 and signal strength of -111 (which seems a little wimpy).
Then I ran a speed test on a local server using Spark LTE. I got horrific latency, poor download speeds, and horrific upload speed... I literally cannot send an MMS message with LTE on. A 144 ms ping, a 2.59 mbps average download time, and 0.15 mbps upload (not a typo!)
Testing EVDO for comparison, performance is generally better with the LTE radio turned off! I got a 61 ms ping, 0.4 mbps download (not great) and 0.85 mbps upload (fast enough to send picture messages at least).
Is this typical for Sprint in downtown NYC? If so, the phone is going back today and I'm off to T-Mobile. Checking Sprint's map, it promises full Sprint Spark, and a few weeks ago when I checked, this area was "Spark Turbo" certified... this seems awfully misleading if "Spark Turbo" is providing only this level of performance in the center of the global finance industry.
