LEXI-R422 offers LTE-M and NB-IoT coverage across 16 bands, alongside software-driven filtering configuration. It also supports 2G fallback, streamlining global deployments with a unified solution.
Delivering 23 dBm RF output power within LPWA bands, LEXI-R422 ensures sturdy connections and minimizes rate repetitions, particularly at cell peripheries, without the need for external power amplifiers, thus enhancing cost efficiency.
Featuring Power Saving Mode (PSM) and extended Discontinuous Reception (eDRX), the module's low power consumption extends battery life up to a remarkable 10 years. Furthermore, it interfaces seamlessly with u-blox M10 modules like MIA-M10 (4.5 x 4.5 mm), forming a powerful duo ideal for compact yet high-performance tracking solutions, particularly in applications requiring continuous tracking and adaptable cellular and positioning power management.
Additionally, LEXI-R422 facilitates easy access to u-blox GNSS services AssistNow Online and Offline, along with CellLocate service for estimating position using surrounding cell station data, negating the necessity for a dedicated GNSS receiver.
Featuring numerous interface options and an integrated IP stack, LEXI-R422 is tailored for an extensive array of ultra-compact, data-centric IoT applications, spanning from personal and pet trackers to telematics (ODBs), industrial automation and monitoring, smart city and building infrastructure, payments, micro-mobility and connected health solutions.
