Ultra-compact single-mode LTE Cat 1bis IoT module

u-blox has released its LEXI-R10, an ultra-small LTE Cat 1bis IoT module in a 16mm x 16mm form factor. The module adapts perfectly to size-demanding designs, making it excellent for use cases, including asset tracking and aftermarket telematics.

Three times smaller than the company's LENA-R8 (256 vs. 810mm2), the module is the answer to the market requirement for an ultra-small LTE Cat 1bis module and is the perfect candidate for applications needing Cat 1bis connectivity without 2G fallback or positioning features. It has been developed as a single-mode LTE-only module. Yet, LENA-R8 is still a reliable option for applications that require 2G fallback and positioning with the embedded M10 GNSS platform.

LTE Cat 1bis was initially introduced in 3GPP Rel 13 in 2016 but only lately garnered market attention in light of the planned or already executed sunset of 2G cellular technology in many regions. LTE Cat 1bis is globally obtainable via LTE networks, yet more affordable than higher data rate LTE categories.

The new module is the smallest single-mode module supplying indoor positioning and a US MNO-certified core. The module also offers Wi-Fi Radio to scan available Wi-Fi hotspots. This information can be utilised by positioning applications through a location-based service like the u-blox CellLocate Wi-Fi.

"The u-blox LEXI-R10 is the right choice whenever size constraints drive the design. For instance, LEXI-R10 adapts perfectly to the requirements of pet and personal trackers. Its convenient size allows designers to explore setups so far unthinkable," says Samuele Falcomer, senior product line manager, Product Center Cellular, u-blox.
