Modem réseau cellulaire ALLNET EC25

Quectel EC25 Mini PCIe is an LTE Cat 4 mini PCIe modem module designed for M2M and IoT applications. It delivers up to 150 Mbps downlink and 50 Mbps uplink and is backward-compatible with EDGE and GSM/GPRS networks. The EC25 Mini PCIe family includes multiple regional variants, offering broad global coverage and integrated GNSS support (GPS, GLONASS, BeiDou, Galileo, QZSS) for reliable positioning. The module provides standard interfaces and software support for Windows, Linux and Android, making it suitable for industrial routers, rugged tablets and other embedded systems.

Advantages

The EC25 Mini PCIe combines high LTE data rates with legacy 2G compatibility to maintain connectivity in areas without 4G or 3G. Integrated GNSS simplifies location features and reduces design complexity. Industry-standard Mini PCIe form factor and broad driver support (USB serial drivers for Windows 7/8/8.1/10, Linux, Android) enable straightforward integration into a variety of M2M and IoT devices.

How to use

Install the EC25 Mini PCIe module into a compatible Mini PCIe slot on the host device and connect required external antennas for cellular and GNSS reception. Ensure the host operating system has the appropriate USB serial drivers installed (Windows, Linux or Android). Configure network settings using AT commands or the platform’s network manager to establish LTE or fallback 2G connections. Select the correct regional EC25 variant to match your operator frequency bands.

Recommendations

Use antennas certified for LTE and GNSS frequencies and place them with clear sky/line-of-sight where possible for improved signal and positioning performance. Verify regulatory approvals (CE, FCC) and operator compatibility for the chosen EC25 variant before deployment.
