Network Congestion

TMO has absolutely oversold their home Internet. My service was great for 1 year- slower speeds than Cox, however, the connection was very stable. Over the past 3 months we have ZERO internet from 5 pm until about 10 pm. Called tech support,, the matter was escalated and they are going to call me back. A Supervisor even called me because I am a 20 year customer. What are they going to do -- it is either add more towers or remove customers!

My family members have demanded we go back to Cox. SuperBowl is coming up and the men in my house are not happy so 15 minutes ago I reconnected Cox and am just reconfiguring a few things..

I wonder what will happen with TMO. If you think about almost every new initiative they undertake ends because of issues on their end --TV, their original prepaid card, their TV portal, their box. their home router for calls etc --the list goes on and on.

I work from home and cannot deal with Internet that does not work.

The pricing is great which is what attracted me and for just about a year it was good and now went back to Cox and got a good deal. I took the price comparable> The option.I used to have the Ultimate and if anything good came out of this I now know that the slower speeds of 100 down work just fine. I never got anything over 25 with TMO and when it worked it was fine.

My prediction for TMO moving forward -- heavy throttling and new pricing options with data caps

Awesome.  Competition is good.  There's no contracts or termination/install fees.  Ive kept Spectrum as a back (cheapest plan) , as i need service for work

I was just contacted by a local company who offered free installation and 1 mo free service for a microwave dish receiver off their transmitter. They got new equipment with a federal grant and they recently set it up to point directly towards our subdivision across the river from their transmitting station. Supposedly will have 25-50mbs 24/7, unlimited and no congestion or throttling. 
I've scheduled the install for Tues. Crossing my fingers it will give us daytime internet.

Will see how it compares over the next few months to what I an getting with TMHI. 
 

BTW, for Pines are one of the highest rated trees for signal blocking despite having no leaves. 

Being behind trees is something that doesn’t help much.  I’ve had service for ~1 year, and did notice that my service SINR/RSRP does take a ‘bit’ of a hit during summer months of a few db.  There aren’t many trees, but during summer, they have a lot of leaves (won’t have that with pine).

SINR here on LTE can drop to ~4dB at times, and up to 14 on LTE B2.  5G n41 is more stable, with SINR around 7.4 to 12.  If I move the device outside, LTE SINR can reach over 20, and n41 can reach around 18.  I’ll be a polling cron on the device to map metrics

RSRP doesn’t change too much, but is typically in the -98 to -103 dBm on LTE B2, and around -103 to -105 on n41.

Middle of the night metrics can be a little better, but in general performance can gain about 100Mbps.

SINR is basically anything that can degrade signal - whether it is congestion from many users or external ‘noise’.  Being rural, I wouldn’t expect too much traffic on the signal (i.e. too many users), but I don’t know the area or what kind of backhaul there is.

Oddly enough, when T-Mobile first deployed 5G  in San Simeon, CA, it was on a T1 (T-Mobile provided that in a written statement to California PUC).  Speed on cells were < 500kbps, with a few hits above 1Mbps.  SINR was …. 30, and RSRP was -57dBm, distance was ~500’.

It was blamed on … congestion, which was partially true.  It was congested because T-Mobile pushed 5g traffic through a T1 circuit.  Once updated, it hit +300Mbps.  Now with n41, its hitting +1400Mbps on a Samsung S21/S23.  

If anything else will help, the newer Arcadyan model has carrier aggregation on 5G carriers + LTE.

in my case, n25 is great on the mobile … however, existing Acradyan kv-21 doesn’t support n25, or 5g aggregation (i.e. no n41 + n41 or n41 + n71, or n25 + n71 combos).

If the SINR is poor on … n41 (likely), n25 could help.  As more bands are switched over … this will help.

Similarly the newer Arcadyan model has ports for antenna build in.

As far as backhaul/deprioritization … I can’t help on that one.  Also, it still doesn’t affect my area (yet!).

Not sure metrics will helpful to this discussion. They are always poor in regards to signal power from transmitter and they are always “good to excellent" in regards to quality of signal received. 

We are rural, behind a state forest of pine trees and according to the current TMHI page my address is listed as “not available” for TMHI. However, it was eligible at one time back in Aug 2022 and since we had no internet and no other options was worth a try. Thrilled back then as we had 200-380mbs until the Monday after Ian hit. FEEMA and contractors came in and congestion dropped it to bewteen 4-12 mbs 24/7 for 4 months. 
 

But since you asked, during today’s 8am speed test resulting in 40mbs, the RSRP on band b2 was -101. The RSRP on band n41 is -97. It's now 10am and speeds dropped to 11mbs. The RSRP is -102 on b2 and -101 on n41. The SINR was 6 and now at 7. The CQI was 10 at 8am and still is 10. 

I’ve tracked the metrics many times daily in the past. For the most part, the SINR increases as high as 12 when mbs speeds are high and can go down to 3 when they are quite low. The CQI remains steady at 9-11. 

Does the lowered SINR (poor signal) refer to network congestion or to deprioritazation or to both? Not that it really matters, since there's nothing else I can do on my end to improve them. 

You may want to post some of the metrics from your Arcadyan device, especially when you're having issues.  Rsrp,  CQI and SINR values can help debug.  When i had TMHI before my site was on 5g, and picking up service from +1 mile away, sinr, rsrp and cqi were all over the place.  Even now, sinr will drop on n41 from 14 to 7 during peak hours.  While indoor i might hit +550Mbps in the middle of the night, it might struggle for 400Mbps during peak hours.   If my signal was poor, all of those numbers would drop.

It is part from signal (more use = poorer sinr/cqi) and then the obvious deprioritization on TMobile home internet

I don't know what you mean by home net vs TMO home net. I have ONLY ONE home wifi network. It’s the SSID of the Arcadyan Router sent to me by TMobile Home Internet (TMHI). It sends out a signal both over ethernet and over wireless to allow my devices to connect to the Internet.

The Arcadyan is connected to an external MIMO 4x4 antenna to boost the the Arcadyan’s ability to receive a signal from the TMobile transmitter on the tower (about 2 miles away in town). The MIMO is mounted outside of the room where the Arcadyan is set up. The MIMO antenna’s wires run through the wall and feed into the Arcadyan. 

In addition to the TMHI set up I have TMobile cellular service on my iPhone. I added a Wilson Whole House Cell Booster system. The Cell Booster Antenna is mounted on a 20 ft high antenna pole. The cell booster antenna’s wire feed in through the attic and down into a room that has a powered device that then boosts the signal into the home’s various rooms.  

If I turn off the Cell Booster unit (wired into its own antenna) then I have no indoor cell phone signal. No bars, just a display saying “no service”. When turned off, if I enable the iPhone setting to use “wifi” (off the Arcadyan) then I sometimes can get one bar but the phone is incapable of receiving calls. If I try to make a call it sometimes rings, sometime doesn't. If it does ring through the caller cannot hear me and the call drops rather quickly. 

I can disable the iPhone setting to “use wifi” and that doesn't affect my ability to make or receive calls as long as the cell phone booster is powered up. When the TMHI is down, my cell phone still works.

If I turn off the Arcadyan and use my cell phone as a “hot spot” in my house (under TMobile’s Magnenta 40GB plan) it is useless. It’s not strong enough for other devices to use. In other words, I can’t use a Chat on a website using my iPad connected to the iPhone’s signal. Website pages take 4 minutes to load, or perhaps never load. 

If I use my cell phone as a “hot spot” in town, the signal is strong enough to share with my iPad. I can chat, download, upload, stream shows, etc. So I know my problem isn't my devices. The problem is the signal strength that I am able to get inside my home. Hence my need for 2 outdoor external antennas- one for the Acadyan and one for the cell phone.

I understand its congestion and beyond my control. 

For the most part I can get things done during non peak hours. What I can't do is use the Arcadyan’s SSID home internet on weekdays between 9am-5pm to do things on my computer or iPad. Things like check email, log into an account, reset passwords, download transactions or chat with support. For example, I’ve been trying to type into this window 3 times. The connection keeps dropping. It finally came up to 2.18mbs so hopefully this post will go through now.

the booster runs off your home net correct? or do you have TMO home net as well?

We left Verizon after moving here due to no signal. Niece visited and she had no ATT signal. So that is why I switched  to TM. With TM, we had a weak signal in front yard. Going outside to talk was a pain. I added a whole house cell booster set up and it has allowed us to make and receive calls inside of our house. 
 

Thanks for info about new Arcadyan. My Arcadyan is already connected to a MIMO 4x4 external antenna directed to the strongest tower signal so unlikely the new Arcadyan will make a difference. 
 

TM needs to work on the congestion issue. Today's a holiday, heavy rain downpour and we have had 30 mbs all day. This evening it's now back up to 120mbs despite all the rain. At 5am this morning I had 180mbs. Every weekend our signal is great. No complaints there. 

I can only conclude TM is deliberately throttling what the Arcadyan is capable of receiving during the hours of 9-5 on working days, M-F.  I would think the engineers could figure out how to lessen work day congestion so we can get more than 0-4mbs. TM received federal money to improve rural Internet access and for that I very grateful. However if we can't use the internet to communicate online during normal M-F business hours then rural access remains a significant problem in the US. 

Id try looking into Verizon or AT&T equivalent. 

Instead of a cell booster, id recommend calling TMobile for the 'newer' Arcadyan which has external antenna.   I have the older with internal,  but the tower is only 1200' away.
