C08: Urban scenarios: small cells, indoor to outdoor, vegetation

Thursday, August 21  13:40-15:40,  Room #20

Session Chairs: Sana Salous, Lorenzo Vangelista

The cellular networks operated by mobile providers are getting more complex every day. In order to ensure a good performance across multiple layers or multiple RATs and to cope with the increasing user demand, realistic modelling of these networks for system simulations is crucial. Simple models that rely on regular network layouts or simple geo-data enable fast computation of system simulation but cannot reflect the dynamic behaviour of modern communication networks. More realistic models reflect the real environment, with buildings, streets, user and traffic simulations and realistic network deployments. In particular, since 80% of the traffic originates from the inside of buildings, the simulation of Pico- and Femto-Cells becomes more and more relevant. This session addresses propagation models for realistic Outdoor-to-Indoor and Indoor-to-Outdoor environments as well as the effect of vegetation.
