Base stations, gateways, systems

All infrastructure elements such as BSs, repeaters, receivers and paging gateways are fully interoperable, interchangeable and controlled via IP.
For ultra–synchronised critical paging networks the precise GPS synchronisation of transceivers is possible, allowing for simultaneous transmission over large areas even in areas with overlapping radio coverage.
In the absence of IP, the 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.
Additional info: paging base stations matrix.
