The test from this hour is not worth much, Plus is the worst mobile operator in Poland. This is LTE900 from BTS to Bohaterów Westerplatte, no matter because it is a 5MHz band, free and always clogged by definition. You have this speed with LTE1800aero2 on this BTS, it works on a 20MHz band, but in the evenings it clogs. Do these tests and show the results from 20-22. So Plus is B535 enough, its network -skansen does not require anything else. WZ> G there are two BTSs from FDD LTE2600, one on Zastal and the other on the church on Mickiewicza 4. If you want to have some meaningful internet from Plus, you need to use LTE2600 + 1800 aggregation of these btSs by forcing them to B535, if the signal on 2600 / 1800MHz will be too weak then you will need an external directional antenna for 1800-2600MHz set to one of them. LTE900, do not bother yourself, it is an empty shell, not LTE. The FDD LTE2600 works like the LTE1800aero2 at 20MHz, so in the B7 + B3 aggregation there is a 40MHz bandwidth available.
