4G (LTE)

The 4G (LTE) mobile connection speed supported by the modem.

All modern LTE equipment is assigned one or another category (Cat.3, Cat.4, Cat.6, Cat.7, Cat.9, Cat.12, Cat.13, Cat.16, Cat.18, Cat.19, Cat.20, Cat.22), on which the transmission speed directly depends. This paragraph specifies both this category and specific speed indicators, moreover, in two parameters — for reception and for transmission. The transmission speed is always much lower, but given the specifics of mobile Internet access, this is usually not critical.

Note that equipment with different speed categories will be quite compatible with each other, however, the throughput will be limited by the capabilities of the slower device. It is also worth saying that this paragraph indicates the theoretical maximum; practical amounts can be noticeably lower (depending on the quality of the network coverage and the features of specific electronics). However, a modem with a higher speed category will perform faster in fact.
