Principles

Your data arrives reliably at the chosen target receivers, all around the clock, via reserved frequencies with sufficient capacity to handle the most diverse applications.

The EFR system and the intelligent radio ripple control receivers open up a range of possible applications, since practically any electrical device and any energy generating device can be controlled via the receiver's relay outputs.

EFR's exclusively reserved long-wave frequencies provide sufficient capacity to transmit weather reports, warnings of bad weather, text messages and other information in addition to the typical EFR telegram transmissions.

This is where the ability of the long-wave system to forward information over a wide area reliably and rapidly is so important. It is no problem to address either individual receivers or groups of receivers, so that targeted distribution of messages can be undertaken.

The receiver devices - such as displays and radio clocks - are battery driven and thus available for use around the clock. This property is extremely useful, for example, in relation to catastrophe warnings.
