The modules are NBFM (Narrow Band Frequency Modulation) 12.5 or 25 kHz channel separation programmable and are based on the Analog Devices AD7021N high performance Narrow-Band Transceiver IC.

The BK2xx complies with the most important Narrow-Band Standards: ETSI EN300 220 ( v2.3.1), FCC Part 15 – Part 95, ARIB STD-T67 .

A narrow channel separation together with a high receiver selectivity allows to obtain an exceptional RF link budget figure of more then 130 dB for a stable and long range
