NARROW BAND
Thanks to its high efficiency filtering, PLM-1 offers high selectivity. Moreover, this filter is a rugged, passive components and allows the receiver front-end to sustain the high-energy noise pulses found in the power line environment.
NARROW BAND
Different transceivers are available, some using narrowband signalling. However they do not offer the high selectivity found in PLM-1 systems. Their selectivity is compliant with that specified under CENELEC standards.
