LTE CAT12 is the next major evolution in LTE networks which is from Rel11 in 3GPP. LTE CAT12 helps improve the download and upload speeds over the 4G mobile network by increasing additional bandwidth and availability. It means better coverage, better speeds, and better reliability.
Category 12 LTE 4G is up to 6 times faster than the first generation of LTE (Category 3, short for Cat3). CAT12 is capable of 600Mbps download and 100Mbps upload. In practice speeds will be much slower than this.
LTE CAT12 offers higher capacity with additional LTE bands available that can be aggregated together to increase capacity and enhance the user experience.
The Proroute H900 and Proroute H685 are both available with CAT 12 modems, the Teltonika RUTX14 also comes with a CAT 12 modem.
