EC25-EFA LTE FDD: B1/B3/B5/B7/B8/B20
LTE TDD: B38/B40/B41
WCDMA: B1/B5/B8
GSM: B3/B8
LTE Version 3GPP E-UTRA Release 11
Quectel EC25 is a series of LTE category 4 module optimized
specially for M2M and IoT applications. Adopting the 3GPP
Rel. 11 LTE technology, it delivers 150Mbit/s downlink and
50Mbit/s uplink data rates. Designed in the compact and unified
form factor, EC25 is compatible with Quectel UMTS/
HSPA+ UC20 module and multi-mode LTE EC20/EC21 module,
which allows for flexible migration among them in design
and manufacturing.
EC25 contains 6 variants: EC25-V, EC25-J, EC25-A, EC25-
AU, EC25-AUT and EC25-E. This makes it backwardcompatible
with existing 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™ location technology Gen8C
Lite (GPS, GLONASS, BeiDou, Galileo and QZSS). The integrated
GNSS greatly simplifies product design, and provides
quicker, more accurate and more dependable positioning.
A rich set of Internet protocols, industry-standard interfaces
and abundant functionalities (USB drivers for Windows XP,
Windows Vista, Windows 7, Windows 8/8.1, Windows 10,
Linux, Android/eCall*) extend the applicability of the module to
a wide range of M2M and IoT applications such as industrial
router, industrial PDA, rugged tablet PC, video surveillance,
and digital signage.
