Base stations, infrastructure elements, gateways, systems

Everything for building systems and system add-ons, for solving any challenge when using wireless telecommunications and paging for individuals, compact mobile groups or large user fleets.

Base stations, repeaters, receivers and paging gateways that are fully interoperable, interchangeable and controlled via IP.
For ultra–synchronised critical paging networks the precise GPS synchronisation of transceivers is optionally possible, allowing for simultaneous transmission over large areas even in areas with overlapping radio coverage.
In the absence of IP-interconnections, the Oelmann paging network remains survivable as the connection continues via the POCSAG radio link.
All the components to build any type of paging system or to complement existing ones as part of an add–on, to update, or as replacement, with full support and a service guarantee.
