In-building Distributed Antenna System (IB-DAS) has been proved to be one of the most efficient methods to provide sufficient coverage and capacity for indoor users. The target of a successful IB-DAS deployment is to guarantee the coverage as well as the capacity of the in-building areas with minimum deployment cost. We consider the optimal deployment of the IB-DAS based on passive DAS in this paper...
In the context of heterogeneous networks, femtocells are very promising. In order to properly simulate their behavior and their impact on the macrocell layer, it is necessary to be able to simulate the radio coverage of femtocells. Hence ParFlow is a possible deterministic model that can be used for such simulation. In this paper two implementations of ParFlow are presented: time domain and frequency...
There are several factors that influence the design of optimal IEEE 802.16e networks. In the first stage of the network development, the most important issue is to find an appropriate solution for the base station location from a given set of candidate sites. The network can be considerably improved if the base station location solution found during the planning phase is designed to achieve optimal...
Based on the management goals of order planning of the iron-steel plants, a mixed integer programming model for the order planning is constructed. The goals include balancing production capacity and minimizing the total cost of infringing contracts. As the data of orders and processes are put together to make a point graph, the problem of order planning is transferred into an improved traveling salesman...
