EC25 IoT/M2M-optimized Cat.4 LTE Module

EC25 series is Quectel’s new generation of LTE category-4 module, optimized specially for M2M and IoT applications. Adopting the 3GPP Rel. 10 LTE technology, it delivers 150Mbps downlink and 50Mbps uplink data rates and is fallback compatible with Quectel UMTS/HSPA+ UC20 module and multi-mode LTE EC20 module in the compact and unified form factor, providing a flexible and scalable platform for migrating from UMTS/HSPA+ to LTE. EC25 contains 4 variants: EC25-AUT, EC25-V, EC25-A, and EC25-E. This makes it backward-compatible with existing EDGE and GSM/GPRS networks, which ensures that it can be connected even in remote areas devoid of 4G or 3G coverage.

EC25 supports multiple-input multiple-output (MIMO) technology, a cutting edge antenna technology capable of transmitting multiple data streams on multiple transmitters to multiple receivers. The antennas at each end of the communication circuit are combined to minimize errors and optimize data speed. The module also combines high-speed wireless connectivity with embedded multi-constellation high-sensitivity GNSS receiver.

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, Linux, Android/eCall) extend the applicability of the module to a wide range of M2M applications such as CPE, router, data card, rugged tablet, automotive, security and industry PDA.

Key Benefits

  • LTE Cat. 4 module optimized for M2M and IoT applications
  • Worldwide LTE, UMTS/HSPA+ and GSM/GPRS/EDGE coverage
  • Compact SMT form factor ideal for small end products with tight space and extended operating temperature range
  • MIMO technology meets demands for data rate and link reliability in modem wireless communication systems
  • GNSS receiver available for applications requiring fast and accurate fixes in any environment
  • Simple migration from 3G to 4G with a flexible and scalable platform
