Wow. I've never exceeded 16Mbps on WiMax. That is admirable.

Just pulled a nice 13.50 down and 3.76 up a Clear Voyager. Believe it or not, better then the 9.34 down and 1.47 up on my current Sprint LTE connection. Not bad. Ping is a bit high though- 80ms compared to 42 on LTE.

Wow...never could pull that with my Voyager when I had it, even though I had perfect signal with low load. Maybe Clear has throttled such devices in the past and is now removing those caps? I had no problem getting 12-plus Mbps with the Clear Hub in the same location.

It was plugged in via USB.

37/17 on 10mhz channels iirc. Problem is Clearwire never had the requisite backhaul for those kind of speeds and we've only been getting faster speeds because CW is prepping sites for TDD-LTE alongside decreases in wimax users.

I have plugged in the Voyager via USB and didn't get any higher speeds than on WiFi. Then again, maybe the Mac drivers are poorer than the Windows one?

So relatively close to the same as LTE? 10mhz is the same as 5x5?

I was actually using a Samsung Ultrabook. It wasn't mine, but the hotspot was.

20mhz TDD has the same total bandwidth as 10x10 FDD however that 20mhz can be divided up asymetrically with varying downlink and uplink bandwidths like 15 x 5 mhz (adds up to 20).

Not exactly. TDD stands for Time Division Duplex. The division between uplink and downlink is in time, not frequency. The entire carrier bandwidth is devoted to uplink, then downlink on an alternating basis.

I assume there is some limit on how much time can be allocated to a single pathway? As in only 90% of the time can ever be diverted to downlink to keep checking if traffic has become available for uplink? Am I way off on that one?

Yeah, the TDD allocation can be changed, though that is a configuration at the network level, as all TDD devices need to maintain a fairly precise synchronization to avoid transmitting while other TDD devices are receiving (and vice versa). If I recall correctly, the default TDD allocation that I have seen for WiMAX is roughly 40/60, uplink/downlink, not taking into the account the guard periods that must be inserted at each link transition.

Otherwise 21-22 x1.5 mbps every day.. Those where the days...

 

Is this even possible? I read earlier that the max down speed for wimax is under 40.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
