We build reliable digital radio paging networks adapted to your needs – on a local, regional or national scale. Our digital paging networks fulfil your requirements, from individual local base stations through to national, efficient radio paging networks.

Compact solutions for local networks

Swissphone_Alerting_Solutions_Paging-Networks_Tab1

In the compact solution radio calls are transmitted over one base station. This base station can provide an adequate signal in the immediate vicinity of the transmitter site to provide a reliable alerting service. Alerting can be triggered locally or remotely over a control center and transmitted to the base station.

Primary-secondary solutions for regional radio networks

Swissphone_Alerting_Solutions_Paging-Networks_Tab2

The regional solution consists of a primary and several secondary base stations switched into a group network. Messages are transmitted over the central base station to the radio network. Base stations in the transmission reception range save the messages and then re-transmit them bit-synchronously to each other. This transmission can take place up to a maximum of 8 times in succession.

Multi-primary-secondary solutions for efficient regional radio networks

Swissphone_Alerting_Solutions_Paging-Networks_Tab3

The efficient regional solution consists of a several primary and secondary base stations switched into a group network. The messages are transmitted over a central base station to the radio network. Base stations in the transmission reception range save the messages and then re-transmit them bit-synchronously to each other. Thanks to the many feed-in points in the radio network transmission repetitions can be substantially reduced despite coverage being over a wider area.

Synchronous solutions for radio networks

Swissphone_Alerting_Solutions_Paging-Networks_Tab4

The most efficient solution consists exclusively of primary base stations that are switched into one network group. The messages are transmitted bit-synchronously over all central base stations to the radio network. The primary base stations transmit bit-synchronously in the first transmission. This radio network configuration means that only one transmission is required for the entire coverage area. When repetition is eliminated, transmission time is minimized.

One solution, different configuration

All the radio network types referred to can only be recognized with the same components given an appropriate configuration. This affords users the greatest possible flexibility in setting up, migrating, and operating their radio network infrastructure. The controlling, configuration and monitoring components PNC (Paging Network Controller) is responsible for the radio network. This software supports all specified radio network types. When configured appropriately base stations can be addressed and configured via a TCP/IP connection or a proprietary radio protocol.

Reliable because of fallback scenarios

The radio network is designed for seamless transition from one operating mode to another. If, for instance, one or several connections in a synchronous solution are disrupted or interrupted, the radio network switches to multi-primary-secondary operating mode. The synchronous base stations that cannot be reached then run in the secondary operating mode until they can be used again as synchronous base stations. If the entire TCP/IP communication breaks down, the PNC can access an individual primary base station directly. The radio network then runs in primary-secondary operating mode. All the other synchronous base stations that no longer have a connection then run in secondary mode, thus maintaining radio network operation. Full functionality is preserved, only message throughput is reduced.
