Quectel AG55xQ

AG55xQ is a series of Quectel’s automotive-grade 5G NR Sub-6 GHz modules, supporting both 5G NR NSA and SA modes. Adopting 3GPP Rel-15 technology, the module supports maximum 2.4 Gbps downlink and 550 Mbps uplink data rates at 5G NSA mode, and maximum 1.6 Gbps downlink and 200 Mbps uplink data rates at LTE-A. Optional PC5- based C-V2X direct communication makes AG55xQ family a great solution for automotive applications since it makes the traffic smoother and more efficient by paving the way for automated driving and fully connected traffic. The module supports DSDA (optional) and provides abundant interfaces for developing customer applications. Its excellent performance in ESD and EMI protection ensures great robustness in harsh environments.

AG55xQ family consists of AG550Q (5G + DSSS + C-V2X), AG551Q (5G + DSSS), AG552Q (5G + DSDA) and AG553Q (5G + DSDA + C-V2X) series, each of which includes multiple modules (AG55xQ-CN, AG55xQ-EU, AG55xQ-NA and AG55xQ-JP) to meet varied market demands. It is backward compatible with existing GSM, UMTS and LTE networks, enabling connectivity in areas without 5G NR deployment and even remote areas without 3G or 4G coverage.

AG55xQ family supports multiple input multiple output (MIMO) technology. Using multiple antennas at the transmitting and receiving ends at the same time in the same frequency band greatly reduces errors and optimizes data speed. While supporting multi-constellation GNSS (GPS, GLONASS, BDS, Galileo and QZSS) based on Qualcomm® IZat™ location technology Gen 9 VT, the module also supports dual-frequency GNSS, PPE (RTK) and GNSS/QDR integrated navigation solutions. This greatly simplifies product design and enables quicker, more accurate and more dependable positioning.

With AG55xQ family, we provide automotive OEMs and tier-1 suppliers with secure and reliable connected car solutions, and vehicle manufacturers with smart and flexible solutions to build self-driving cars. More specifically, the module is commonly used in telematics boxes (T-Box), telematics control units (TCU), advanced driver-assistance systems (ADAS), C-V2X (V2V, V2I, V2P) systems, on-board units (OBU), roadside units (RSU), and other automotive/traffic systems.
