Following up the successful TC35i/MC35i Terminals, the new generation of GPRS Terminals is available. Based on the powerful MC55i wireless module platform the improved.
Terminals offer additional functionality while remaining compatible with its predecessors.


MC55i Terminal packs a Quad-Band GSM/GPRS baseband with TCP/IP connectivity based on GPRS Class 10 data transmission into a compact plug-and-play housing. The robust
housing includes a range of common interfaces as well as an integrated SIM cardholder which make the new generation to an all-in-one solution enabling voice, data, SMS and fax communication.
The new generation is available as Quad-Band with GPRS Class 10 functionality (MC55iT) and as a Dual-Band variant with GPRS Class 8 functionality (MC52iT). With an extended temperature
range, the reliable terminals can be used in a wide range of M2M business fields such as metering, remote maintenance, traffic systems, transportation and logistics, and security.

Like all Cinterion products, MC52iT / MC55iT come with full type approval (FTA) and are certified according to automotive e-mark as well as by the largest carriers worldwide.

Quectel EC25 Mini PCIe IoT/M2M-optimized LTE Cat 4 Module


Quectel EC25 Mini PCIe is a series of LTE category 4 module adopting standard PCI Express® MiniCard form factor (Mini PCIe). It is optimized specially for M2M and IoT applications, and delivers 150Mbps downlink and 50Mbps uplink data rates.

EC25 Mini PCIe contains 5 variants: EC25-J Mini PCIe, EC25E Mini PCIe, EC25-AU Mini PCIe, EC25-V Mini PCIe and EC25 -A Mini PCIe. This makes it backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can be connected even in remote areas devoid of 4G or 3G coverage


UC20-E Mini PCIe: 900/2100MHz @UMTS, Quad-band @GSM UC20-A Mini PCIe: 850/1900MHz @UMTS, 3G only UC20-G Mini PCIe: 800/850/900/1900/2100MHz @UMTS 850/900/1800/1900MHz @GSM


EC21 is fallback compatible with Quectel UMTS/HSPA+ UC20 module and multi-mode LTE EC20 module in the compact and unified form factor. EC21 contains 5 variants: EC21-V, EC21-A, EC21-E, EC21–AUT, and EC21-AUTL. This makes it backwardcompatible with existing EDGE and GSM/GPRS networks, which ensures that it can easily migrate from LTE to 2G or 3G networks.
