[srslte-users] S1 handover

[Modyngs]

Thanks for the replay

Can we also use B210 as master eNB and limesdr as slave eNB to do s1
handover?

Also I think they should be sync to each other! If yes do we need some GPS
signal or some external device to be placed in order to Handover between
two eNBs while using COTS UE, or they will sync using EPC signals?


P.S : I'm gonna use 3 PCs. One for EPC, one for master eNB using B210 and
the other slave eNB using limesdr. COTS would be a samsung S series!

Is this setup theoretically work?

Thanks
Best regards
