The most commonly used wireless technology in Europe for meter reading is Wireless M-Bus. The installation base is tens of millions. The first solutions used mode S and T on 868 MHz. These has later been complemented with mode C. also at 868 MHz, optimizing current consumption and thereby enabling drive-by reading requiring more frequent transmissions. Mode N using ultra narrowband technology at 169 MHz is growing in popularity due to its long range and robust operation even in un-friendly environments seen by water and gas meters. Radiocrafts has a leading role in the standardization of narrowband technology at 169 MHz in CEN, which publish the EN 13757-4 norm.
