Radio base station(RBS) is the key infrastructure in wireless network and the main product of Ericsson. To improve the efficiency and success rate of RBS maintenance is therefore necessary and beneficial to Ericsson. Augmented reality is a promising solution by annotating computer generated guiding information on real world to enhance the information received during the maintenance. This thesis developed a workable AR application for RBS to evaluate the feasibility and difficulty of applying AR on RBS. Based on Android platform, the application used Vuforia from Qualcomm and Unity as tracking and rendering package respectively. Tracked result was imported to Unity and processed by low pass filters to remove noise. Filtered data was then used to build a distributed world coordinate frame array to cover the entire RBS panel. On this distributed world coordinate frame array, digital contents such as audio, animation were placed and controlled by a task state machine. Drove by the user control in user interface layer, the task state machine provide a flexible task scheduling scheme for task navigation. At last, digital contents and real time video captured by phone camera were synthesized and rendered on the cellphone screen. The result presented a practicable AR solution for RBS maintenance and reveals the advantages and disadvantages of deploying AR technology for RBS. Certain suggestions were also described based on the development.
