Thanks to the combination of 900/2100 MHz, 850/1900 MHz multi-band WCDMA and quad-band GSM technology, the UC20 supports backward compatibility for EDGE and GPRS with multi-slot Class 12. Hence, this technology ensures global network coverage for M2M applications. The maximum data transmission rate for HSPA+ is 14.4 Mbps downlink and 5.76 Mbps uplink.
The 32x29x2.5mm unit operates in the -40 to +85°C temperature range for use in various building automation, medical and industrial applications. It draws only 3.1 mA in sleep mode and 570 mA in UMTS voice mode. Diverse interfaces such as two UARTs, USB 2.0 high speed, Digital Audio (PCM), two A/D converters, extensive driver support for Windows, Linux and Android, highly integrated software functions such as File System, eCall and Firmware Update, and Quectel Enhanced AT Commands, provide UC20-users with an almost unlimited spectrum of possible fields of application. A complete UC20 development kit with hardware, software, specification, application notes, debug and test tool, approvals and test reports are available for evaluation purposes.
