Comparison of measurements and simulation model of indoor signal level variation in LTE networks
This paper describes the measurements of the signal level changes in LTE networks in different indoor conditions and compares them with OMNeT++ simulation scenarios. The simulation models are matched with the measurements to have the same average signal level for stationary client. Next the mobility model is applied in the simulation and compared with the measurements of the user moving within a building. The comparison has been executed for signal level changes for mobile phones and tablets in three indoor usage scenarios: stationary, office and home mobility. The results show that the popular mobility and signal propagation models give a significantly different variance of the changes of signal level compared with the measurements and are not correctly representing the variance caused by indoor fading.
