The goal of higher vocational education is professional training of students. Teaching contents related to practical training are the most important for preparing students for work in real-life conditions. The mobile learning model presented in this paper analyzes the possibility of implementing augmented reality in the process of educating vocational engineers in the domain of postal networks. The technology of augmented reality was introduced with the goal of making access to learning materials easier, as well as improving the interaction between materials and students. The paper compares the results of traditional learning and learning using augmented reality in the part of the curriculum important for vocational skills. The described model was implemented in the course titled Postal Services Practicum in the final year of vocational studies at the ICT College of Vocational Studies in Belgrade. The participants in the model were students studying a curriculum in the domain of realizing postal services. The goal of implementing the model is to show that augmented reality shortens the time of realizing a task, as opposed to realizing it using printed materials, as well as the fact that the efficiency of solving a task is higher as opposed to the traditional method.
