And why did you take the offer in Orange in addition to 315 / It is poor, expensive and B315 does not meet the requirements for your Orange infrastructure. As I wrote, BTS NetWorks are there after modernization, 4 LTE bands work with their aggregation. Do LTE2600, LTE2100, LTE1800 and LTE800 tests on this B315, force them on it with LTEWatchH
http://www.lte-anbieter.info/ltewatch/count_huawei.php?Datei=ltewatch_h BTS-CID data will be shown and signal parameters, plus speedtest on each. You will see how each of them works for you. Cybertech's antenna works on LTE1800, LTE2100 but also on LTE2600 at this distance from the BTS. After the tests, we will see which bands are best to use and which router to buy. B525 aggregates two LTE bands, you can force them with HManager. The three bands are aggregated by B715, i.e. LTE2600 + LTE1800 + LTE800, does not aggregate LTE260 + 2100 + 1800. The cost is about PLN 500, come from Play.
