LTE still had trouble connecting even when LTE only set.

I decided to change my data connection to LTE only for my trip from Texas to Kansas. That way I should not have to toggle to get LTE to connect since there would not be a CDMA connection alrady established connection to change when LTE was available.

 

Well guess what? LTE still would not connect even though the iPhone had and LTE connection.

 

1. I connected once in Wichita Falls but soon lost it and never connected again there even though the iPhone maintained an LTE connection while in Wichita Falls.

 

2. iPhone connected at the south Kansas border, Evo finally connected after toggling.

 

3. Evo never connected in Wichita KS, iPhone always connected

 

4. Automatically connected from Andover, KS to El Dorado, KS

 

5. Finally automatically connected in Overland Park.

 

I cleared the LTE file so I could log all connections on the trip. No connections were logged until I set the connection to LTE/CDMA/EVDO auto when I got home.

 

Note: When connected LTE, there were not NID or BID info in netmontior when LTE only selected.

I discovered a different way to get "LTE only"

First, you dial *#*#4636#*#*

Then you scroll down a tiny bit and there is a little triangle on the right. If you press that, you get a list of options. If you select the bottom option "LTE, CDMA" you will connect to 4G without any problems. If no 4G is available, then you will revert to a 1X connection. This trick worked great for me when I was mapping 4G in my area. There are some downsides. For example, you can't get 3G. Also, I didn't have any luck staying connected to 4G for long. YMMV

To change back you do the same thing and select "CDMA + LTE/EvDo auto"

    • Cool find! Been there since 2018 according to Cellmapper. The only other time I've seen them leave up a temp site like this for a long period of time was when a nearby site is temporarily inoperable like the one in Red Hook Houses. That doesn't seem to be the case here and it's pretty much a GMO site at this point. My best guess is that T-Mobile wanted to put a site there to fill in coverage but because it's on LGA's grounds getting the actual permission to do so is extremely complex so they worked out a deal with the Port Authority to put up a COW in the meantime.  
    • Would this be a T-Mobile COW outside LGA Terminal A? eNB 49106 seems to line up to its position, plus the arm for the trailer to hook onto a truck says T-Mobile. Here is the NYC streetcar view the image was pulled from.     For all the years I have been monitoring the DAS, I have never gotten -55 or better, even after passing by every antenna in a station that is deep enough to have 0 outside macros reaching in. The SNR is still 20+, so its probably designed that way on purpose.
    • From a few days back: https://www.fiercewireless.com/wireless/deutsche-telekom-aims-50-t-mobile-ownership-2024 DT Chief Executive Timotheus Hoettgas said buying the majority stake in T-Mobile US was the group's most important strategic project at present, according to Reuters. He said that stake should top 50% much sooner than its previous projection of 2024. Earlier this year, DT paid $2.4 billion to SoftBank Group to increase its stake in T-Mobile US to 48.4%.
    • 5.9GHz finally approved by a court: https://www.fiercewireless.com/tech/court-upholds-fccs-decision-59-ghz.  This should be added to 5GHz wi-fi.  considering wi-fi 7 will be included in the qualcomm x70 and related SOCs, doubtful they will be able to add this now, unless designed to be added later.  5.9GHz will given us a third 160MHz unique carrier iirc, a major improvement.
    • waiting for about 400 with demand > supply, or 95% to look again in some detail.  Until then : https://www.sashajavid.com/FCC_Auction108.php#county_details_table_overlay
