TL;DR: Results suggest radio path clearance increases with height, leading to an increase in number of cells in the detectable range and in the set of neighbors within 3 dB of the serving cell in the receiver, indicating neighbor cells are closer to each other in the power domain.

TL;DR: The results show the potential usage of the cmWave band for mobile cellular services in the years to come: the NLOS path loss slopes at 10 and 18 GHz are not much different from the 2 GHz reference, and the corresponding offsets are in the order of 20-23 dB for 25 m Tx height, which is expected to be overcome by the usage of high-gain miniaturized steerable antennas.

TL;DR: Results show that deploying In- band relays can significantly reduce the user outage if high backhaul link quality is ensured, whereas Out-band relaying and the usage of a lower frequency carrier at the Macro layer guarantee better network coverage and capacity improvements.

TL;DR: It is concluded that change of the serving HS-DSCH cell without any intermediate channel switching to DCH seems to be a promising solution from a performance point of view as it allows us to have full HSDPA cell coverage and high capacity gain from introducing H SDPA.

TL;DR: The feasibility requirements for ultra-reliable communication are analysed and the loss margins against path loss, shadow and fast fading are obtained, and the effect of increased interference due to higher deployment density on offered reliable rates and packet delays is studied.
