16 x 16 mm LTE-M / NB-IoT module with 23 dBm RF output power and 2G fallback

u-blox introduce its new LEXI-R4, smallest LTE-M / NB-IoT module customized for size-constrained application requirements. Measuring 16 x 16 mm, it supports all LTE-M and NB-IoT bands with an RF output power of 23 dBm, also offering the possibility to operate on a 2G network. It is suggested for asset tracking applications such as pet and personal trackers, micromobility devices, and luggage tags. It can also be used for other applications, such as alarm systems, vending machines, and stolen vehicle recovery, to mention a few.
U-blox LEXI-R4 has been conceived for size-demanding designs that proved challenging for previous modules, although still providing the same capabilities. The compact size results from a 40% footprint reduction in dimensions compared to the previous u-blox SARA-R4. The gained space can be used to potentially host larger antennas, which can improve RF (Radio Frequency) performance, or to accommodate larger-size batteries. Another prominent feature of LEXI-R4 is its 2G fallback capability. Whenever LTE-M / NB-IoT coverage conditions are not optimal, it keeps functioning by falling back onto a 2G network. This feature is highly convenient in countries where LTE-M / NB-IoT networks have yet to be fully deployed. Natively designed to support GNSS (Global ...
