Sudden terrible (and strange) data speeds at home, TMo Tells me the towers are "fine"
I'll try to be brief, but have a bit of data to share. First, let me state that T-Mobile supports reps are super nice, BUT cannot think outside of the narrow box they are trained in and really can't ...
BBB escalation will get you a bit more than the typical locals, but I have had your message of “we can't guarantee coverage in all areas” often.
I’d almost recommend taking a ‘drive by’ the tower (½ mile away?) and taking a ‘test’.
and similarly network readings.
I did mention above that it took me a CPUC written complaint to get T-Mobile to ‘fix’ the 0.3Mbps 5G service, along with a BBB escalation. 8 months .
Then, after publishing the written response, it was fixed in 1 month. Press them on the issue - tell them you have full bars, but effectively unusable service. 5G 'should be' +100Mbps (according to past reps). 1Mbps at ½ mile is pretty bad, especially with good power level, and usable SINR.
Why I mention microwave … I'm in a suburban area, the local tower here is microwave. A 'bump' (wind, or other) can move these a bit out of alignment - or … something comes in between. For the amount of spectrum available and signal, your results (2 weeks ago) were decent.
The other question is more … how much bandwidth is available on each band ?
LTE is kinda low, but decent (all 3 bands should aggregate) for ~100Mbps or more
RSRP is really good, while the SINR is kinda ‘meh’.
- How much bandwidth is on n71 (eg. I have 15x15)
- How much bandwidth is on n25 (eg. I have 20x20).
- Does is make much difference toggling 5G SA vs NSA ?
Eg. S23 will aggregate LTE B2 + B66 (B4) + 5G NSA n41
Where I'm, 5G NSA doesn't work with n25 … only SA. Also, 'if' you could (Samsung) switch to n25 SA only … vs n71 SA only vs LTE only.
typical where I am, my SINR is better, but RSRP is worse - from the worst location indoors.
B2 LTE (15x15): 49Mbps / 4.4 Mbps
B66 LTE (20x20): 70Mbps/8Mbps
B12 LTE (5x5): 15Mbps/5.7Mbps
B71 LTE (10x10): 27Mbps/11Mbps
LTE B2+B66+B12 : 130Mbps/9Mbps
n25 SA (20x20): 90Mbps/14Mbps
n71 SA (15x15): 46Mbps/20Mbps
n41 SA (100 + 40) 245Mpbs/4Mpbs
5G SA auto (n71 + n41) 230/15Mbps
5G NSA + LTE (LTE B2 + LTE B66 + n41) = 360Mbps/6Mbps
Best results (outdoor, clean line of site ≈ 700Mbps/140Mbps)
Better site (same spectrum) ~=2Gbps/140Mbps.
Tower ≈ 1200’ away through trees and part of a building
