With the help of a mobile device running a simple Android or iOS operation system the maintenance staff has access to the worksheets, they can look through the detailed work description and then report completion of the work and its work demand without having to go to the central office. They can even look at new work any time updated on a map, to see where the given work needs to be performed. As a result of this a lot of travelling time can be saved both by the optimal scheduling of the sites and by not having to travel between the centre and the sites.
With the help of the mobile application it is possible to report breakdowns from the site, and even a photograph can be taken of the failed device to ensure easy planning by breakdown reports via the mobile application. In the case of preventive maintenance the exact GPRS coordinates are stored to make sure that the report really originated from the equipment they had tested.
