The GSG-F21P module is a multi-function wireless positioning module that integrates a GSM/GPRS engine and a high-precision GNSS engine. The F21P module integrates RF, baseband, power management unit, power amplifier, and GNSS. It has an ultra-small size and is easy to integrate into a variety of applications. The low-power technology of the F21P module meets the needs of today's low-power applications.

    The F21P module offers a proven solution that reduces cost and time to market. This module is suitable for almost all M2M industry applications, including logistics management, shared equipment electronic fence management, driverless, precision agriculture, personal tracking services, remote automatic monitoring and control, security systems, anti-theft systems, automatic emergency calls, wireless POS Machines, smart meters, wearable devices, etc.

    The F21P module supports 4-band GSM/GPRS with operating bands of GSM850, EGSM900, DSC1800 and PCS1900MHz. The GSM part of the F21P module embeds data transfer protocols such as TCP/UDP, PPP, FTP, HTTP, and SSL. Its embedded extended AT commands make it easier for users to develop applications.

    The GNSS receiver embedded in the F21P module integrates BD and GPS systems. It supports multiple positioning and navigation systems including BDS, GPS, SBAS and QZSS, and supports AGPS fast assisted positioning. At the same time, it supports single-frequency RTK high-precision positioning. The Dayami class is ideal for centuries. High receiving sensitivity, high positioning accuracy and low power consumption.
