RB550A is a series of automotive grade 5G NR Sub-6 GHz modules developed by Quectel, supporting both 5G NR NSA and SA modes. Adopting 3GPP Rel-15 technology, the module supports maximum 2.2 Gbps downlink and 550 Mbps uplink data rates at 5G NSA mode, and maximum 800 Mbps downlink and 200 Mbps uplink data rates at LTE-A. Supporting optional C-V2X PC5 direct communications, RB550A series is a great solution for automotive applications and makes the traffic smoother and more efficient through paving the way for automated driving and achieving the goal of fully connected traffic. It supports DSDA (optional), and provides abundant interfaces for customers to develop applications. Its excellent performance in ESD and EMI protection ensures great robustness in harsh environments.
RB550A series consists of RB550A (5G + DSSS + C-V2X), RB551A(5G + DSSS), RB552A(5G + DSDA) and RB552A(5G + DSDA + C-V2X) variants, each of which contains multiple models (RB550A -CN, RB550A -EU, RB550A -NA and RB550A-ROW) to meet varied market demands. It is backward compatible with existing GSM, UMTS and LTE networks, enabling it to be connected in areas without 5G NR deployment currently and even remote areas devoid of 3G or 4G coverage.
RB550A series supports multiple input multiple output (MIMO) technology. Using multiple antennas at the transmitting and receiving ends at the same time and on the same frequency band greatly reduces errors and optimizes data speed. The module supports Qualcomm® IZat location technology Gen9VT Lite (GPS, GLONASS, BDS, Galileo, QZSS). The optional QDR 3.0 and the integrated dual-frequency (L1 + L5) GNSS receiver simplify product design greatly and provide quicker, more accurate and more dependable positioning capability.
With RB550A series, we are able to provide automotive OEMs and tier-1 suppliers with secure and reliable connected car solutions, and also provide vehicle manufacturers smart and flexible solutions to build self-driving cars. More specifically, the module will be commonly found 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.
