Abstract :
This contribution deals with the impact of human crowds on the wireless propagation of programme making and special event applications. The survey is based on a ray tracing model of a concert hall that was verified with a wideband measurement campaign in the absence of humans. The channel characteristics are compared for a different amount of human beings inside of an applicable line of sight scenario in the time domain by means of the delay spread. Furthermore the composition of exemplary channel impulse responses as well as the interactions of its multipath components are discussed in detail.
