LTE Linking to two towers??

Wed Jan 06, 2021 9:57 pm

Hi All

I have a question hoping you can help. can a lte modem connet to two cell towers?

i.e tower one useing band 20 and tower 2 useing band 20, can you use the CA to link them together ( getting better speeds )!

Im not sure i i explanined myself hoping you can help.

I may be wrong, but CA is done from the one tower, not a band from multiple towers.

right,

do we know if multi tower support is achievable?

or is it better to have multi sim setup and lock the sims to a tower each?

Multi-tower support is there, but not all networks support it and not all CA-capable terminals support it.

However, I don't think B20 intraband CA is supported at all (even for single-tower setups). And CA only works for cells usung different frequencies. LTE networks are SFN (single-frequency nerworks) which means adjacent towers use exactly same frequency (carrier) and due to interference issues CA is not feasible in such case.

Whether you'd actually gain something by connecting to both towers depends on geometry: if by using narrow-beam high-gain antennae you can make signal from chosen tower dominant, then yes. If both towers are in approximately same direction, then probably not.

I guess they have one tower with quad signal senders.
