Review on 4G LTE modem HUAWEI E3372h-320 White by Kio Proviax ᠌

Stands in a country house under remote video surveillance. Hong Kong region. Used in conjunction with the Keenetic Extra router (KN-1711). A MIMO antenna is plugged into the modem, which gave a real signal gain of the order of 5-7 dBi (with the gain promised by the antenna manufacturer of 15 dBi). The Amazon tower is about 5 km away (line of sight). As a result, the Internet speed is sufficient to watch video (with the H.265 codec) in real time without delays from 8K cameras. For six months from November to April, the modem worked completely autonomously without failures or breaks. Channel and speed keeps stable in any weather. In winter, the temperature was up to -50C, but the connection "did not fall."
