“…Our architecture used LTE-advanced time division duplexing (TDD) in the backhaul network. This configuration aids in the usage of TDD time synchronization that will minimize intra interference in the proposed architecture [28]. Moreover, because our study assumes that all the land-based cellular network is offline; further inter-cell interference is ruled out too.…”

Today’s wireless networks provide us reliable connectivity. However, if a disaster occurs, the whole network could be out of service and people cannot communicate. Using a fast deployable temporally network by mounting small cell base stations on unmanned aerial vehicles (UAVs) could solve the problem. Yet, this raises several challenges. We propose a capacity-deployment tool to design the backhaul network for UAV-aided networks and to evaluate the performance of the backhaul network in a realistic scenario in the city center of Ghent, Belgium. This tool assigns simultaneously resources to the ground users—access network—and to the backhaul network, taking into consideration backhaul capacity and power restrictions. We compare three types of backhaul scenarios using a 3.5 GHz link, 3.5 GHz with carrier aggregation (CA) and the 60 GHz band, considering three different types of drones. The results showed that an optimal UAV flight height (80 m) could satisfy both access and backhaul networks; however, full coverage was difficult to achieve. Finally, we discuss the influence of the flight height and the number of requesting users concerning the network performance and propose an optimal configuration and new mechanisms to improve the network capacity, based on realistic restrictions.

“…However, if the frequency resource is not properly allocated, then the system performance will decrease due to interference [3]: co-tier interference from a neighbor femto BS and cross-tier interference from a macro BS. Signal quality will decrease as a result of higher levels of interference.…”

In heterogeneous network, femtocell is deployed inside macrocell coverage. Femtocell and macrocell use the same frequency as the resource. Thus, if the resources are not properly allocated, the interference will arise. The higher level of interference results in decreasing signal quality. Therefore, interference management is needed to increase network capacity and system performance. This research implements particle swarm optimization (PSO) algorithm to minimize interference on the heterogeneous network. Based on the simulation results, it is shown that PSO algorithm works efficiently to increase the throughput value of femto user equipment (femto UE) up to 62,2 Mbps by minimizing the interference.

This paper addresses the planning and design of contemporary networks of mobile telecommunication where an existing network is subject to far-reaching development and modification and, thus, an evolution with diverse requirements of users and a diverse density of network cells. This leads to considering the diverse variants of network designs. When several variants of network designs are available, an investor might ask for a ranking of these variants. The investor is obviously not bound by the results of such a ranking and might select a variant that is not the highest in the ranking, but an objectified ranking might help in the selection. Therefore, the paper presents a way of computing and examples of ranking objectified multiple criteria and (if possible) not requiring the determination of weighting coefficients.
