Celab Four:C Mobile

Mobile task management

Job ticketing solution developed in cooperation with public safety users. The solution is available for Android, Windows and the the navigator Actis.

About Celab Four:C Mobile

The purpose of Four:C Mobile is to simplify task- and status management between user in the field and command centres. This is achieved by presentating task information and enabling navigation to the associated destination as well as providing one-touch reporting.

Status reporting

The solution is delivered with configurable status buttons, of which some are particularly accessible. Statuses can be programmed to be sent to separate recipients by either TETRA ISSI, RUI/RUA or MSISDN.

Statuses can also be configured to initiate automatic procedures. Status “arrived” can erase current route as well as initiate a remote talk group change on connected radios ¹.

Four:Mobile-for-android-v1Four:C Mobile Android v2.0 supports split screen allowing both job tickets and navigation to be visible simultaneously.

Communication management

Four:C Mobile is a GUI placed on top of a device. That means you can control both the device and the connected radio from the application. From the menu you can set radio mode (TMO/DMO, Gateway and repeater). A transition to gateway mode can also initiate a switch to DMO on associated radios remotely ¹. Features like contacts and talk group lists are also accessible from the main menu.

Task management

Incoming tasks are saved in the system and activates the information display while sounding an alert tone. When the button “confirm” is pressed a status is sent to the dispatch centre and depending on attached information a few things happen².

  1. If the received task contains coordinates the navigation window can be activated by pushing Navigate./li>
  2. If the task specifies talk groups these will be accessible in the top right corner. Although, to permit use of these they have to be programmed in the connected radio.
  3. If the job has associated resources they can be contacted by pushing “Call resource”.

¹ Requires a TETRA terminal with the features Call Out and/or SDS remote activated.

² Four:C Mobile is optimised for concatinated text templates.
³ Features may vary depending on device- and OS.

Android (v2)

The latest addition to the family offers the same "Tetra-related" features as its predecessor supplemented with features like web links, file transfers and integration of cloud services and dispatch solutions. The Tetra-connection manages task management, status reporting and remote control via a Tetra-terminal over a bluetooth-connection. But they day that the infrastructure is ready the solution supports these features over alternative carriers (LTE, wifi, etc).

Since Android is the most common OS for mobile devices a lot of advantages are inherent. Thanks to many parties are driving the development is is highly future proof regarding performance, features and compatibility with carriers and APIs. At the same time the OS is already available on a myriad of devices, ensuring that there is hardware available for every deployment.

A synergy with Four:C Mobile for Android is also the simplified administrative management of the devices. Configurations, updates and device management can now easily be done remotely, simplifing implementation.
