“…Over the past few years, the concept of densification has been exploited for enhancing data rates. The researchers in [13] have argued that at some point further densification will no longer be able to provide exponentially increasing data rates like Moore's law. Traditionally, simple path loss model is used for coverage analysis.…”

Abstract:Recently tools from stochastic geometry have gained much attention for modeling and analysis of dense cellular networks. Although extensive studies are available in literature in this respect, the approaches are generalized and often lack significance towards practical scenarios where network conditions vary dynamically. The main objective of this research is to provide some insights into the stochastic geometry based analysis of cellular networks through suitable modifications so that it can be used to estimate parameters of interest i.e., intensity and coverage probability for different tiers and scenarios under consideration. The main definition for probability of coverage has been re-defined and complete closed form expression is derived. The intensity for different tiers have been estimated with the help of proposed approach, beyond which no more gain in coverage probability can be achieved. Monte-Carlo simulations have been performed for validation of proposed approach and results are also compared with stateof-the-art approach.

“…According to Andrews et al in [4], densification of wireless networks for enabling data rate increase by spatial reuse is reaching a fundamental limit. Even though the standard path loss model shows that the SINR becomes density-independent starting from a given value of density, when considering the dual slope path loss model instead, the authors come out with a SINR decreasing monotonically with density in dense networks.…”

Abstract-Energy efficiency of a network, defined as the number of bits transmitted per unit of consumed energy, increases with the traffic load for a constant network capacity. This comes from the fact that energy is composed of two components: a fixed one, consumed by the network regardless of the traffic load, and a variable one, which depends on the traffic load. And so, when traffic load increases, the fixed component gets amortized. However, a network upgrade, namely adding more equipment in the network to fit traffic increase, comes typically with a higher increase in capacity than traffic, at least for a while after the upgrade, as traffic previsions are based on relatively long term projections. Thus, the power consumption of the network would increase faster than the traffic, and energy efficiency would then decrease. We investigate in this work the conditions under which a network upgrade does not deteriorate its energy efficiency. We consider two ways of upgrading a network: either by adding equipment with the same technology or by deploying equipment with another technology, typically more recent and more efficient. We discuss in both cases the number of equipment to be added so that to preserve the network's energy performance.

“…The successful commercialization of mobile communications has generated increasing demands for high‐speed data transmission (Boccardi et al, ; Furht & Ahson, ; Schwarz & Rupp, ), which, in turn, has motivated the development of a variety of technologies. Cell splitting (Andrews et al, ; Bhushan et al, ), realized using directional radiation patterns of sector antennas, which makes the frequency reuse possible and further enhances spectrum efficiency, appears to be the most appealing. Based on the scenario of splitting large cells into smaller cells, cell sectorization (Athley et al, ; Lee et al, ), which adopts broader frequency bandwidth, dual‐polarization channels (Cui et al, ; Luo et al, ), spatial diversity‐based multi‐input‐multioutput (Larsson et al, ; Ngo et al, ), and multibeam coverage technologies (Ericson et al, ; Swales et al, ), has been developed to fulfill communication requirements.…”

This paper examines the radiation characteristics of a shaped reflector antenna applied as an outdoor base station antenna for mobile communications. A simpler architecture in a reflector antenna can reduce the implementation cost and complexity of a base station antenna. The aim of this reflector antenna design is to resemble the required radiation characteristics of conventional base station antennas, which employ a single‐column phased array of antennas to radiate directional beam patterns for radio coverage in cell planning, while improving the existing drawback of overly large beam overlapping in adjacent sectors. It also discards the beam forming circuits of conventional base station antennas to reduce the level of passive intermodulation. This reflector antenna is fed by the elemental antenna of conventional base station antennas and is thus equipped with the functionalities of beam tilting and dual‐polarization radiation to fulfill the requirements of adaptive sectorized cell adjustment. Both numerical simulation and measurement results are presented to demonstrate the feasibility.
