MikroTik RBLHGR&R11e-LTE6 poor LTE connection

Hi masters of LTE connections

I’ve bought me a RBLHGR&R11e-LTE6 and I’m having trouble getting a useful connection.
My goal is to get at least 5MB/s stable (yes, I’m modest) but reliable - non-failing.

I installed everything and when I just pointed it into random direction it would give me -106dBM RSRP.
The MikroTik web interface shows that RSSI and RSRQ is very nice but the RSRP (receive signal strengh that is, right?) is horrible.
When I try to optimize the direction I can get something like -99 dBM RSRP at very best, rather around -102 RSRP.
Strange, when I point it straight up into the sky it gives me like (still) -106 RSRP. The correct direction to the LTE carrier antenna doesn’t seem to play a huge role. Isn’t that odd?
The bandwidth I get can be like 2-3MB/s and what’s worse - it’s very unreliable. No ping for several minutes happens every 5 minutes. Up/down/up/down…

I have another LTE router from Huawei, it’s B818 263 that one also doesn’t get any strong signal connection but shows the following…
-11.0dB
-104dBm — < here also sometimes it’s -99 at best though, not great
-75dBm
9dB

… but the difference is this actually delivers easily 20MB/s and in 2 weeks my constant pings show that there was like 2 disconnects for 2-3 seconds in 14 days.

I’m testing from the antic/loft of the house so I can’t get any higher, opening the window and placing it on the roof doesn’t change the signal so for my testing I placed it behind the window.

My thought was that a directional LTE modem (MikroTik) would work superior at weaker signals. Also the correction direction would play a big role but it doesn’t in my case, odd, isn’t it?

Any idea what I could do?

Thanks for suggestions,

David

around 50Mbps

SINR should be bigger then +10
RSRP should be below -80

You must log changes in Tower / Cell to be sure you not hop between two sectors of the same tower, or maybe between two towers…

Few stuff
B818 Cat.19 vs R11e-LTE6 Cat.6
B818 without external antenna vs LHGR+R11e-LTE6 who have own antenna
Check R11e-LTE6=B525 vs EG12~B818

B818 probably connect and assign/aggregate/sum few Bands together, your details give info about only one band, are not complete.

The most important is a

  • monitor properly LTE
  • use a CellLock to lock a primary-band who lock the Tower and his sector antenna and you not hop to other what give you a stability.
  • use a Cell Monitor feature to detect what else towers you can connect and do Cell Lock and SpeedTest to them to grab information what Tower are fast/slow.

This is my general answer.
