The MC90 from Quectel is a quad-band GSM/GPRS/GNSS/Wi-Fi module that supports hybrid positioning technologies including Cell ID and Wi-Fi aided positioning. This module is based on MTK's MT2503 platform and supports dual SIM single standby function. It integrates a multi-GNSS system, including GPS, GLONASS, Galileo and QZSS. The GLP (GNSS Low Power) power saving mode ensures great positioning accuracy with ultra-low power consumption of less than 1.2 mA. A built-in LNA provides the module with improved RF sensitivity and exceptional acquisition/tracking performances even in weak signal areas. The MC90 is an ideal choice for a wide range of IoT applications, such as bicycle sharing, student ID card, vehicle tracker, wearable device, pet tracker, asset tracker, driving recorder, etc.
The module also supports EPO technology which provides predicted Extended Prediction Orbit to speed up TTFF without the need of any extra server. Based on EPO data, QuecFastFix Online function further reduces TTFF in cold start, while the EASY technology enables a very fast first fix when there is not enough satellite information. The module provides a rich set of Internet protocols such as TCP, UDP, MQTT, PPP, FTP, HTTP and SSL, and supports audio, QuecFOTA and OpenCPU.
