A very pleasant trip to see friends sees the successful installation of a wAP ac LTE kit (RBwAPGR-5HacD2HnD & RTLe-LTE6) at their B&B in Croatia. The device is mounted on an external wall with excellent line of sight view of the transmitter 2km away. Cellmapper.net shows that the mast offers bands 1,3,20. The cellular report is mainly excellent which was good.
On a wired connection, we were getting download speeds of 60-70Mbps consistently and once we even got nearly 100Mbps. We’re more than happy with this but just wondered if this is the maximum we can expect from the R11e-LTE6?
The mast does support 5G and my mobile could get 120Mbps. Friends are more than happy as before with the Teltonika RUT950 they were only getting 20Mbps (CAT4) plus they’ve got Wi-Fi out on the terrace. But is it possible to add a 5G module to this router?
Yes I knew it was rated at 300Mbps hence my reason for asking. The installation is pretty good and the signals are excellent so wondered if there was some additional settings and/or SIM card limitation. It’s a Croatian SIM.
That modem supports only 2CA, mobile phone supports more thats why you get better speeds on phone.
I recently installed also here in Croatia HT link but with https://mikrotik.com/product/lhg_lte18#fndtn-specifications
It connects to 3 freqs same time and i was getting over 300mbit with not even full signal.
Do not draw false conclusions from individual observations. LTE speeds fluctuate so much that it is difficult to make reliable conclusions in a short period. Changes should be observed over a longer period to identify a trend. However, saying “I reduced the MTU and now I get 75 Mbps instead of 70 Mbps” (that’s what I read when you say “did help a bit”) may be completely unrelated to the MTU change at all.
Better leave the MTU at default (usually 1500) and if on Linux do a ping with a excessive packet size (30000)
ping -s 30000 -M do 1.1.1.1 -c 1
you should get something like
PING 1.1.1.1 (1.1.1.1) 30000(30028) bytes of data.
ping: local error: message too long, mtu=1500
Here is your proper network MTU size. No need to tinker.
Thanks everyone for their comments. Sadly I’m not in Croatia anymore. My friends are back out there and they’re quite happy with 60-100Mbps most of the time so we’ll leave it. It was a very cost effective solution for the holiday home as it supplied LTE modem, outdoor Wi-Fi and routing functionality for the CAPsMAN network of six cAP ac inside.
The LTE18 kit looks great but would have added considerably to the cost and complexity. Would have needed to run another cable for an additional outdoor access point plus cost of a router - although guessing the LHG LTE18 could act as that.
