Quectel module combines four bands for better tracking
August 21, 2018
Chinese IoT module supplier Quectel Wireless has released a quad-band GSM, GPRS, GNSS and wifi module that supports hybrid positioning technologies including GNSS, cell ID and wifi aided positioning, and enables position tracking in indoor and outdoor environments.
The MC90 integrates multi-GNSS system, including GPS, Glonass, Galileo and QZSS, which improves the positioning accuracy and ensures that the module can track position even in areas with weak satellite signals. This makes it suitable for urban areas with high-rise buildings and complex environments.
For blind spots of satellite coverage, it adopts wifi hotspot positioning technology to address indoor positioning demands in scenarios such as factories, schools, shopping malls, hospitals and nursing homes.
In addition, it integrates multi-aiding positioning technologies to improve GNSS performance. It supports EPO technology, which provides predicted extended prediction orbit to speed up TTFF (time to first fix) without the need of an extra server.
Based on EPO data, the QuecFastFix online function reduces TTFF in cold start, while the Easy technology enables a fast first fix when there is not enough satellite information. Moreover, GLP (GNSS Low Power) power saving mode ensures positioning accuracy with low power consumption. The built-in LNA provides the module with improved RF sensitivity, acquisition and tracking performances even in weak signal areas.
Based on MTK’s MT2503 platform, the MC90 has a compact design and low power consumption, and supports the dual SIM single standby function. The module also provides a set of internet protocols such as TCP, UDP, MQTT, PPP, FTP, HTTP and SSL, and supports audio, QuecFota and Open CPU.
The module suits IoT applications, such as bicycle sharing, student ID cards, vehicle tracking, wearable devices, pet trackers, asset trackers and driving recorders.
Engineering samples are available now.
