Module maker u-box intros new LTE-M and GNSS ‘combo’ items for low-power IoT


Swiss IoT module maker u-blox has introduced two new LTE-M mobile module sequence, the SARA-R52 and LEXI-R52, designed for industrial IoT functions. Each are based mostly on its UBX-R5 mobile chip and combine GNSS positioning. The agency is pitching them for monitoring and monitoring functions within the utilities and logistics markets, in addition to within the healthcare sector. 

The R52 sequence introduces a brand new “combo module” to supply simultaneous GNSS and LTE-M connectivity – described as “essential for functions requiring steady or cyclic monitoring”. The SARA-R520M10 has an built-in GNSS receiver (M10) for “concurrent low-power monitoring, higher time-to-first-fix (TTFF), and improved radio (RF) sensitivity,” the corporate stated. “It’s tailor-made for customers who [want a] pre-integrated mobile and GNSS answer,” it added.

The LEXI-R52 supplies the identical options because the SARA-R52, however in a smaller kind issue (16x16x2 mm) – “superb for ultra-small functions like wearables”.

A bunch of latest options within the UBX-R52 chip have been flagged, additionally, meant to dispense with extra componentry and cut back the footprint and prices related to IoT growth. The GNSS positioning characteristic, referred to as SpotNow, supplies a 10-metre repair on an IoT machine inside a “couple of seconds”. “It’s meant for infrequent monitoring functions equivalent to recycling waste dumpsters, aged trackers, or cleansing machines,” stated u-blox. 

Apart from, u-blox has a compute processing unit (‘uCPU’) that enables customers to run their very own software program throughout the chip with out utilizing an exterior microcontroller unit (MCU). The agency’s connection supervisor (uSCM) software program is designed for “automated connectivity administration [for] both finest efficiency or lowest energy consumption” – within the occasion a connection drops, for instance, it stated.

The R52 sequence presents 23 dBm of RF output energy, in comparison with 20-21 dBm in most LTE-M modules. “This ensures  steady connectivity in difficult protection situations.” Samples can be found now; quantity manufacturing is predicted within the third quarter.
