Highlighted by Cassidian was its Xerigo 3 data radio module for TEDS (TETRA Enhanced Data Service). Supporting 25 and 50 kHz channel widths, this is equipped with standard data interfaces from the IT world – RJ-45 ethernet, IP and USB.

Tero Pesonen, head of Cassidian’s Fortecor mobile data programme, commented: “For public safety, it’s a wonderful thing that now they can rely again on a mass-market stabilizing feature on things like the interface to mission-critical connectivity – and in that sense, reduce the cost of integration, because that tends to be far higher than any of the device costs.

“Now, simply, you plug the ethernet cable in at both ends, and from the data terminal or laptop’s point of view, it’s just another LAN. I believe that the management of these terminals will probably in due time move away from the radio departments to the IT department, because it is just another IT device from their point of view – another IP device. And that’s significant.”

• Also demonstrated on the stand was a TETRA data package developed with Portalify. This enables pictures be transmitted simultaneously to an unlimited number of terminals by group addressing, using very little network capacity. “With the same application run on WAP, for instance, it is individually addressed, and cumulative usage of capacity may be an issue, especially in networks which are already loaded anyway”, Mr Pesonen said. “So if you are able to send it to a group address, then that really makes a difference.”
