So I think I ran tests on approximately 40% of the Denver area sites in all my testing. On my spreadsheet, my average speedtest was an impressive 38Mbps. My lowest download was 12Mbps. And my highest was 53Mbps. I did see some peaks around 58-60Mbps, but they would always drop to the lower 50's by the time the test completed. About 35% of the sites were above 40Mbps. I am not able to definitively determine the cause of the speeds not reaching anywhere near their theoretical maximum. I am 100% sure that the airlink is not saturated. Not even close. If Sprint has sold more than 200-300 triband hotspots in the entire Denver metro area at this point, I'd be shocked. That means on average, there is one user per sector currently. It could be an artificial limit created by the network, or a backhaul limitation. I truly expected to find one site/sector that was 60-90Mbps. I found several sites with what appeared to have 4, 5 and even 6 sectors. However, when looking at the antennas, I could never locate more than three physical sectors. Every sector was Channel 40978. Thank you to all who donated to the Denver trip. Your donations paid for just over half the costs. It is greatly appreciated!! Robert

I didn't have service when you donated. I upgraded you when I got back onto coverage. Only an hour or so after you donated. Thanks for supporting S4GRU. Sent from my SPH-L900 using Tapatalk 4 Beta

I've hit a lot of 30-50Mbps zones on Denver's TDD-LTE network. But nothing faster than I've hit my hotel room so far. Sent from my SPH-L900 using Tapatalk 4 Beta

It may just be YouTube doesn't like the hard handoff. I'm not certain. It may take just a tad longer than an FDD handoff. Sent from my SPH-L900 using Tapatalk 4 Beta

OK...here are the results of the Band 25/Band 41 handoff testing in Thornton. Pretty good... In browsing, loading websites, etc. I did not notice the threshold at all between bands. When running YouTube (a grumpy cat video), it paused when I transitioned from one band to another. Band 25 to 41. And Band 41 to 25. It would transfer without pausing when I transferred within the same band. I transitioned on Band 25 to the second Band 25 site in Thornton without pausing. I also changed off between Band 41 sites without pausing, no problem. To just quickly hit the play button again though was a pretty minor inconvenience. All things considered, I think it worked well.

Some photos of Site # CO-DEN1227 on top of the Renaissance Hotel at Stapleton. Strangely, I found four sector ID's, but only three panels. I tried to get to the side so I could maybe zoom in on the labels. But there was a dang abortion clinic in the way. Robert Christina has run into the pharmacy to get me some motion sickness pills. I'm about to barf trying to use this laptop, read tiny numbers while she is driving. :puke:

There is a new Band 25 LTE site in Thornton, adjacent to some Clearwire TD-LTE 2600 sites. I'm going to see if I can do some hand off testing. Robert

No, Mr. J.W. Marriott was quite a prude. Robert

This is the best Band 25 test from my hotel. Seeing how the nearest site is approx 8 miles away, that's not bad at all. -113dBm RSRP, Cell ID 138486529. Robert

Best final result so far inside the hotel. We are now calling the valet for our car and about to go mobile. I have had to switch to the 12GB hotspot plan for the remainder of this billing period. I'm burning through the GB's! AJ is twitching. Robert EDIT: Got one even slightly better:

Definitely. I will be updating them on the Premier Sponsor TD-LTE site map. Robert via Samsung Galaxy Note 8.0 using Tapatalk

So far, every site I've connected to has been 40978. I'm keeping track of everything. I will definitely post any differences I come across. Robert via Samsung Galaxy Note 8.0 using Tapatalk

Moving the testing out to the balcony. Sent from my SPH-L900 using Tapatalk 4 Beta

I think with the all the WiFi pollution in my current location, switching to WiFi will result in lesser speeds. Even if it is dual stream. So it will not be conclusive here. When I take this testing mobile later, I'll give it a whirl. Robert

I'm now consistently hitting 43-47Mbps tests at this time and signal. Robert

OK...In my hotel room using my Netgear Zing 771S USB tethered to my laptop, bypassing the WiFi, this is the best result I got on Download... It peaked around 56Mbps, then steadily dropped until it stopped at 47Mbps at the conclusion of the test. In contrast, my Note 2 got this: So I believe my Note 2 is getting a lot of WiFI interference from several competing WiFi signals in my hotel. Using the laptop tethered directly to the MiFi is the way to go. So far if you cherry pick the best test result items, here is what I've encountered USB tethered to laptop: Best Download speed: 56Mbps peak, 47Mbps completed test Best Upload speed: 18Mbps Best ping: 58ms So far the best test result using the Note 2 on WiFi: Best Download speed: 36Mbps Best Upload speed: 20Mbps Best ping: 88ms
