You choose the equipment because you pay for it, choosing a MiFi mobile router for home applications is a mistake. The consultant has no right to push him unless you wanted cheap, i.e. for PLN 10 / month. But these types of devices can be bought for around PLN 100-120, in addition they are better Huawei E5577, E5573 or MF-910. The latter two are on offer from Plus. LTE desktop routers are used for home applications, the minimum is B315 (worth PLN 300) and the best equipment with LTE-A, Plus's offer is E5186 and recently DWR-960. Equipment worth about PLN 500-600, aggregating two LTE bands. You are within the LTE-A Plus range. LTE1800Aero2 and LTE800Sferii operate on the BTS Plus Plus Rachocin. the antenna from the link is electro-junk not even worth one zloty. At Allegro, such offers and companies are bypassed. The description is a steak of marketing nonsense and the profit sucked from your finger. You have a router without aggregation of LTE bands. On LTE1800 aero2 has 20MHz bands in MIMO and DL up to 150Mbps, on LTE800Sferia only 5MHz band and DL up to 37.5Mbps. In practice, the speeds depend on the signal parameters but above all on the BTS load. The range on LTE800 is larger so you can connect with this band. On DWR-932 there is probably no choice of LTE1800 bands or LTE800 (check the menu) You would have to do tests under BTS and see how LTE1800Aero2 works. For testing you can use MiFi or a phone with LTE and the Network Cell Info application, shows BTS data and signal parameters, and speedest tests will show how much can be achieved on LTE1800 with the correct LTE1800 signal and how busy the BTS is. Plus does not guarantee speed, as a rule the internet works well for two weeks (probably give priority on BTS), after this time it varies. looks now DL and UL speedtest?
