• Power optimized and cost-effective positioning with SpotNow receiver
• Cost-effective, power efficient, end-to-end IoT communication with MQTT Anywhere and MQTT Flex

The LEXI-R520 IoT module in a compact 16 x 16 mm form factor is based on the u-blox UBX-R52 cellular chipset. LEXI-R520 occupies about 60% of SARA-R520’s PCB space without affecting the overall LTE and positioning performance, making it ideal for size-constrained devices like personal/pet trackers, telematics, industrial automation and monitoring, smart city and smart building, payments, micromobility, and connected healthcare. LEXI-R520 supports power class 3 (PC3), with a maximum output power of 23 dBm across all the bands, ensuring robust connections and preventing data retransmission effects at cell edges.
Thanks to the full ownership of the hardware and software building blocks, u-blox can provide the longest device availability and lifetime support for the entire R5 platform, down to the chipset level.
The module supports LTE Cat M1 and LTE Cat NB2 technologies based on a comprehensive set of 3GPP Rel. 14 and Rel. 15 features that are relevant for IoT applications, including improvements on power consumption, coverage, data rate, and mobility.

Location information on LEXI-R520 is provided by SpotNow, the cost-optimized positioning feature running directly on the UBX-R52 chipset, which removes the need for a dedicated internal or external GNSS receiver. SpotNow is based on an Assisted GPS receiver solution, which is power-optimized for occasional tracking use cases. Alternatively, position can be estimated via LTE cell station signaling data using CellLocate, which also elimitates the need of a dedicated GNSS antenna.

LEXI-R520 is compatible with u-blox's MQTT Anywhere and MQTT Flex communication services by which data overhead, time spent on the air, and energy consumption can be reduced, thus enabling users to extend device life cycles, lower costs, and improve ROI.
