The iU891A-XL is a compact and cost–effective USB stick based on the iM891A-XL radio module that operates in the unlicensed 868/915 MHz band and combines a powerful Cortex® M4 controller with the LoRa® transceiver of Semtech® corporation.
It supports LoRaWAN® and all major unidirectional and bidirectional wireless M-Bus modes (S, C, T, and combined C/T).
With an integrated +22 dBm power amplifier and a sensitivity of -149 dBm, a sensational link budget of approx.
170 dB can be reached. This makes the iU891A-XL an ideal solution for smart metering applications connecting water, heat, electricity, and gas meters with data concentrators or IoT sensors, as well as home, building, and industrial-automation.
The external antenna provides an outstanding performance even in difficult RF environments and allows ranges of >15 km (LoS).
