alarm to check with the user if he is fine, or if he’s just having a coffee-break or something. It can either be a voice alarm, or something like blinking the display, or vibrate, or all of them. And then, in case the user does not respond to the alarm, the radio will send an emergency call together with the [location] coordinates to a predefined address.” Other types of alarm can be employed – for
example, the radio could be coupled to an electrocardiogram sensor to monitor front-line fire officers or oil rig workers for stress. Te radio can also be made to send a status message to the control room at the time when the local alert is generated, to warn of a possible incident to come. In addition, a GPS-based ‘Where are you?’
function displays the location of other team members on the THR9i’s QVGA colour display, and the locations can be saved as waypoints for alter use. Te THR9i is supported by a wide range

O
n show in Europe for the first time at PMRExpo was the THR9i radio from Cassidian. Its special feature is its
Lifeguard function, a man down alarm, which can be activated at the press of a button. “If the radio falls down or if it stops moving, after a certain period the radio realizes that there might be something wrong with the user”, explained Aila Kotilainen. “It will first generate a local
of audio and other accessories, and Cassidian also offers a terminal management tool which can update and configure several radios simultaneously.
Elsewhere on the Cassidian stand was this mock-up showing the driver’s control panel for a front-line vehicle of the future. “You can use all the functions by the touch screen”, said Mikko Ahonen, pictured here. “It’s actually our radio inside and you can place a call, send a status message or an SDS, or switch the lights on the roof, etc. You have, as well, a vehicle navigation application and video. You can have many applications running in your one central PC.”
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
A
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.”
