In today's cellular networks, it becomes harder to provide the resources for the increasing and fluctuating traffic demand exactly in the place and at the time where and when they are needed. Moreover, a cellular network which can cover indoor areas and hot-spots is a complicated and expensive task. Therefore, a new hierarchical topology is put forward to solve the problem, and the topology have application...
Incorporating relay nodes in cellular networks, e.g. UMTS/ HSPA, is beneficial for extending coverage as well as for service enhancement. In this paper we study the inter-cell interference generated by a relay-enabled cell and how this influences the performance of mobile users. The performance measures of interest are the inter-cell interference distribution, realized rates and flow throughput. Our...
In this paper, we evaluate analytically the capacity gain if we use the HSDPA system in band VIII. This work is based on a statistical approach that calculates the cell capacity knowing the throughput at each distance to the base station. This throughput is obtained by thorough simulations that take into account the propagation, environment (urban/rural, indoor/outdoor) and different mobile categories...
This paper describes concretely the assessment of the GSM900 Base station transmission influence on UMTS900 Equipment receiver in coordinated deployment case according to some spectral masks in reception. This work is based on theoretical approaches which quantify the GSM interference level and shows the filter importance in coexistence issues between UMTS900 and GSM900. In order to minimize the GSM...
