Quectel EC25 is a series of LTE category 4 module optimizedspeciallyfor M2M and IoT
applications. Adopting the 3GPP Rel. 11 LTE technology, it delivers150Mbit/s downlink and
50Mbit/s uplink data rates. Designed in the compactand unified form factor, EC25 is
compatible with Quectel MTS/HSPA+UC20 module andmulti-modeLTEEC20/EC21 module,
whichallows for flexible migrationamong themin design andmanufacturing.
EC25 contains 6 variants:EC25-V, EC25-J, EC25-A, EC25-AU, EC25-AUT and EC25-E. This
makesitbackward-compatiblewith existingEDGEand GSM/GPRS networks, ensuringthatit
can be connected even in remote areasdevoidof 4G or 3G coverage.
