Hi There All,
I have finally got my LHG LTE all set up with my 4g EE phone sim . I am getting Band 3 ok …115 db, ..albeit only 10 mg, [ not bad considering the tower is 30 miles away ! ].
HOWEVER .. on my Galaxy s10 I get 114 db LTE 4g on Band 20 from the same tower !. When I only tick Band 20 on quick setup , hoping to get the same 4G LTE on the modem IT WONT PICK IT UP … very strange, especially when I know the 4G band 20 signal is there. !
Any suggestions guys …i am stuck.
on latest firmware and software.
thanks

Depends on particular LHG you’ve got … but so far every Mikrotik LTE antenna I checked had lousy gain for low bands (B20 and B8 … something between 0 and 5 dBi) and decent to good gain for high bands (B3 around 15 dBi, even higher for B1 and B7).
The difference in gain is significant.
… and … whenever possible … recheck with another device, where you can also see the configuration and connection-state …
it’s possible your provider does not want you, with your device.(-identifier) on that frequency ( at that time … with that contract … whatsoever )
… it’s a policied planet … it’s a bug planet ! … not my opinion ! … Paul Verhoeven’s opinion !!
Thanks for the info guys. Yes , I didn’t expect it to have much ,if any gain on 800mhz, However I did expect the modem to pickup ,even recognize Band 20 LTE. …My phone gets it right away ,because its the strongest signal. The Band 3 one is too weak on the phone . The lhg lte dish makes a good job of Band 3 !
very strange…Thought there might be one of those hidden settings on Webfig ???
Its the same sim i use for
both devices, Why would EE let me receive Band 20 on the phone ,but not on the Mikrotik
HELP
RSRP (if your signal strength numbers are this) of -115dBm is about absolute minimum for LTE to work at all. And it only allows low throughput (up to Mbps or so), furthermore link won’t be stable (a few dB higher loss due to bad weather and you loose the link). For the very same reason, a few dB lower antenna gain means no service.
So again: in such challenging radio conditions the only way out is to use better antenna … read: larger, ugly looking with higher gain for low frequency band. And by large I mean at least 1.5 f not 2 metres long (high, diameter … depends on antenna type), which inevitably means higher wind load and higher possibility for lightning strikes.
It can’t be fixed in software if it physically isn’t there … and in radio technology, antennae matter a lot. Even though software architects and fashion designers want you believe otherwise.
Sussed it out…My band 20 signal is LTE-A . I now need a CAT 6 modem , The one I am using is Cat 4 .
