Abstract or Introduction
The work is intended to give the reader an overview of WLAN-based indoor navigation. In addition, it is shown that such navigation is already possible within buildings and it also shows which obstacles still exist. Due to the rapid development of mobile devices, especially with regard to their performance, the possibilities of navigation with these devices are increasing. Especially in the area of indoor navigation there is still a lot of potential. The problem is that the GPS signal is not available inside buildings and therefore navigation is not possible with normal applications, as these no longer receive a signal from the satellites and thus the position of the mobile device can no longer be determined.
For this problem, the technical variants of indoor navigation are used, which are explained in this paper. However, the possibilities of indoor navigation also have their problems. Many technologies have a high acquisition value, since the map material has to be made available first and usually has to be digitized first. In many areas, the technology must first be retrofitted in order to really achieve the desired performance. The accuracy of the position determination also plays a role, so it is important that the technology can guarantee high accuracy when it comes to calculating the position. The topic is of particular relevance to us because these technologies have great potential and enable seamless navigation that takes place inside buildings. Especially the multitude of possibilities makes the topic very interesting and it is important to find out which of these technical possibilities is really suitable for use and will be so interesting for the user.
