Quectel SG520B smart modules

Quectel Wireless Solutions has launched the SG520B series of 5G Sub-6 GHz, Wi-Fi 6E and Bluetooth smart modules. The module series has been developed to meet growing needs for smart modules which can support connectivity along with a variety of functions, such as edge computing capability, graphics processing, multimedia and operation of peripherals such as displays, cameras and touch panels. The modules feature a built-in, up-to-date Android operating system and are based on the Qualcomm QCM4490 64-bit octa-core processor from Qualcomm Technologies, Inc.

Offering comprehensive cellular connectivity options including worldwide 2G, 3G, 4G and 5G coverage, with LTE Cat 15 and both 5G Release 16 standalone (SA) and 5G non-standalone (NSA), the modules offer 5G and LTE multiple input multiple output (MIMO) technology. The utilisation in MIMO of multiple antennas at the receiver end at the same time and on the same frequency band helps minimise errors and enhance data speed.

Further connectivity choices include 2x2 MIMO Wi-Fi 6E, IEEE 802.11 a/b/g/n/ac/ax. and Wi-Fi dual band simultaneous (DBS), with a peak data rate of up to 3.6 Gbps. The smart modules also offer Bluetooth 5.2 and the option of a multi-constellation global navigation satellite system (GNSS) receiver for applications that require fast fixes in any environment.

Designed for industrial and consumer applications, typical use cases include smart gateways, customer premise equipment (CPE), Mi-Fi devices, point of sale (POS) terminals, cash registers, dashcam, digital signage and industrial PDAs etc.

Available in a 42.5 x 56.5 x 2.95 mm LGA package, the SG520B Series has an operating temperature range of -35 ~ +75°C. The modules also support 1080p H.265/H.264 video encoding and decoding.
