Access Point Placement in Beyond 5G LiFi-RF HetNets
Due to the rapid increase in the number of mobile phones and other handheld devices, an enormous pressure is placed on the already overloaded cellular networks to provide the required Quality of Service. Heterogeneous networks, with multiple coexisting and collaborating technologies like 5G, WiFi, and LiFi, have emerged as a good solution to increase capacity.
In order to guarantee optimal coverage, avoid interference and minimize costs, the cellular base stations and WiFi/LiFi access points have to be placed optimally in the environment.
Working knowledge of Python
Sound knowledge of Wireless Communication
Interest to learn new communication technologies
Experience with optimization problems is an advantage
The topic is related to human blockage modeling in 5G and beyond systems. We would like to model blockages and evaluate their impact on user quality of service because having a line of sight is very important for communication technologies that use high frequencies such as LiFi and mmWaves. The loss of line of sight leads to frequent handovers, which in turn result in a data transmission interruption.
In the future, more data will be transmitted wirelessly, especially in aircraft cabins. However, cabin channel models are scarce especially for LiFi. Therefore, we have developed a 3D structure of an aircraft cabin in blender. The next step is to develop a statistical description of channel model by adapting an existing raytracing engine such as LuxCore.
