Intermittent Service t-Mobile 5G
I just received my 5G gateway and have set this up. I'm a software engineer with a solid knowledge of electronics and telecoms but I'm not up to date with latest stuff.
Anyway I have the device setup, we also have ADSL but I want to explore 5G so I subscribed to see how it behaves.
I have a single PC cabled into the gateway, nothing else in the house communicates (yet) with the gateway (my phone does talk to the gateway over wifi to inspect it, but that’s all).
I got a 3bar signal and set the unit on my desk and it seemed OK, very much faster than ADSL.
But after an hour I began to get randomly "No internet" and the device had disconnected. This has been the case for the past two hours now. Up then down like 10 mins, 5 mins, 2 mins, 8 mins uptime then brief loss of connection.
The 3bar signal strength seems steady.
There are a primary and secondary signals reported on the web page that proves the gateway.
Does anyone have any idea what lies behind these disconnects?
My zip is 85207 and all indications are we have “5G Ultra Capacity” I am a few miles away from various buttes that have lots of towers, one is west of me and during the setup my phone indicated a signal source west of me, so I’m assuming that tower is the location of the signal.
Because of these buttes and my proximity to them and no tall buildings around I’d assumed I was advantageously placed.
So what to do? I can see numerous threads about this from other people, is the service really that poor?
My ADSL - though much slower - has no reliability issues, up 24/7.
Filtering for the n41 5G NR bands only. I can see the n41 and n71 both. There may be another tower with that PCI value but it is not in the database.
- Red
- Bandas 5G: N41, N71
- Bandas 4G LTE: B2, B4, B5, B12, B71, B66
- Red
Curious, I wonder if eNB ID 884107 - LTE Cell 131 PCI 166 at E-W. Apache Trail and S. Meridian Drive is now an n41 5G NR signal. That is just NW of eNB ID 884106 - LTE.
Ah, it looks like there are high voltage power lines running SW to NE just south of that R/C Airpark? Just north of East Brown Road. I don't know if the marking across is for high voltage power lines or not but I believe they are. There might be some noise introduced that impacts the cellular signals. I don't know how far you are from the tower but if the power lines intersect the Fresnel zone it might be possible some EM from the flux on the power lines is related to the noise. Just speculating as I am not a cellular expert.
With cellular communications you always have to consider external factors that can impact the signal. Again I don't know your actual location so you can map out the findings on Google Earth and consider the distances and the terrain and just see what jives.
OK all my problems were connected with DCHP, see the other thread:
