Description

Quectel UC20-G 3G IoT Mini PCIe is a series of powerful functions UMTS/HSPA+ module featuring a maximum data rate of 14.4Mbps downlink and 5.76Mbps uplink. It is designed to provide customers with global network coverage on the connectivity of HSPA+/WCDMA. The module is fully backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can be connected even in remote areas devoid of 3G coverage.

UC20 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 an 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 7/8/8.1/10, Linux(Raspian), Android/eCall) extend the applicability of the module to a wide range of M2M applications such as an industrial router, industrial PDA, rugged tablet PC, minicomputers like Raspberry Pi, video surveillance and digital signage. The compact profile of 51.0mm × 30.0mm × 4.9mm in standard Mini PCIe form factor and the high integration level enable integrators and developers to easily design their applications and truly benefit from the low power consumption and convenient Plug and Play function.
