Wireless Internet Modem – Category 12 – Quectel EM120K-GL (New Platform LTE-A) – The Wireless Haven

More Details

Quectel’s EM120K-GL is an LTE-A Cat 12 module based on the 3GPP Release 12 which supports a theoretical peak data rate of 600Mbps downlink and 150Mbps uplink.

Designed in an M.2 form factor, the module is compatible with Quectel’s LTE-A Cat 6 module EM06 series/EM060K-GL, Cat 12 modules EM12-G/ EM121R-GL/EM120R-GL, Cat 16 module EM160R-GL and 5G modules RM500Q/RM502Q series, which facilitates customers’ migration between different caetgories.

The EM120K-GL is designed for the global market and nearly covers all the mainstream carriers worldwide. The module supports Qualcomm IZat location technology gpsOne 9HT (GPS, GLONASS, BDS and Galileo). The integrated GNSS greatly simplifies product design, and provides quicker, more accurate and more dependable positioning capability.


NOTE:  It is strongly recommended to invest in a quality power strip surge protector (i.e., APC, Belkin,…) to use behind a router and/or electronic equipment.  This will help protect against Transients (momentary spikes/surges in voltage or current) that can be detrimental to expensive equipment.  Transient damage to modems are not covered under warranty Protect your equipment.

IMPORTANT:  Exercise extreme caution while installing MHF4 connectors to the modem antenna ports.  The ports are delicate and easily damaged.  Assure that the MHF4 connector is perfectly centered, level and aligned with the modem port.  The MFH4 connector will then snap into place using minimum pressure.  Do not apply excessive force.  A damaged modem connector port is not covered under warranty.
