Quectel EC25

IoT/M2M-optimized LTE Cat 4 Module

Quectel EC25 is a series of LTE Cat 4 module optmized specially for M2M and IoT applicatons. Adoptng the 3GPP Rel. 11 LTE technology, it delivers maximum data rates up to 150Mbps downlink and 50Mbps uplink. Designed in the compact and unifed form factor, EC25 is compatble with Quectel mult-mode LTE Standard EC21/EC20 R2.0/EC20 R2.1/EG25-G/EG21-G modules and UMTS/HSPA+ UC20/UC200T module, which allows for fexible migraton among them in design and manufacturing.

EC25 contains 13 variants: EC25-E, EC25-EU, EC25-EUX, EC25-J, EC25-A, EC25-V, EC25-AF, EC25-AFX, EC25-MX, EC25-AUT, EC25-AUTL, EC25-AU and EC25-AUX. This makes it backward-compatble with existng EDGE and GSM/GPRS networks, ensuring that it can be connected even in remote areas devoid of 4G or 3G coverage.

EC25 supports Qualcomm® IZat™ locaton technology Gen8C Lite (GPS, GLONASS, BeiDou/Compass, Galileo and QZSS). The integrated GNSS greatly simplifes product design, and provides quicker, more accurate and more dependable positoning.

A rich set of Internet protocols, industry-standard interfaces and abundant functonalites (USB serial drivers for Windows 7/8/8.1/10, Linux, Android/eCall*) extend the applicability of the module to a wide range of M2M and IoT applicatons such as industrial router, industrial PDA, rugged tablet PC, video surveillance, and digital signage.
