A Comparison of RF Exposure in Macro- and Femtocells

چکیده

This paper assesses radio frequency exposure of a mobile handset user in the context of a new class of cellular base station: the femtocell. Traditional cellular network construction relies on using a single base station to cover a large area and serve dozens to hundreds of users. The femtocell (named after the minuscule size of the coverage area) provides a low-power in-home cellular connection for the mobile handset. Consequently, we expect it to behave differently to a macrocell in terms of the users radio frequency energy exposure. Our work focuses on the trade-off in incident power on the mobile handset user when connected to either a macrocell or femtocell using power loss and power control models. Contrary to many individuals initial feeling that putting a base station in your home would increase exposure, our findings indicate that having a femtocell in the home will actual reduce the mobile handset users exposure to radio frequency energy.

Estimation of Pathloss in Femtocells for Indoor Environments

Femtocells Access Points (FAPs) are low power base stations which improve the cellular service within indoor environments. RF propagation modeling is required to analyze the femtocell performance, power issue and the interference impact on the macro network. An indoor propagation channel is considerably more antagonistic than an outdoor channel. This paper deals with the path loss and coverage ...

SimTown: RF Propagation Models for Urban Femtocell Environments

Femtocells are miniature base stations (BS) improving cellular service typically within indoor environments such as homes or enterprise buildings. Analyzing femtocell performance and interference impact on the macro network requires the use of detailed RF propagation modeling, particularly in scenarios where user mobility is involved. This paper addresses this requirement by developing such mod...

A Stackelberg game-based spectrum allocation scheme in macro/femtocell hierarchical networks

Femtocells widely deployed in a macrocell form hierarchical cell networks, which can improve indoor coverage and network capacity, and have been regarded as one of the most promising approaches. However owing to the absence of coordination between the macro and femtocells, and among femtocells, decentralized spectrum allocation between macro and femtocell users become technically challenging. I...

Lte-a Sharing Relationship in Macrocell and Femtocells for Spectrum

Heterogeneous networks (HetNets) are likely to provide a ubiquitous access to the mobile broadband services as they involve various small cells, each targeting a different environment in the network. However, the application of the advanced resource allocation techniques is highly needed in order to handle the inter-cell interference and fully exploit the benefits of such networks. In this stud...

Analysis of Handover Decision with Adaptive Offset and Link Quality Threshold in Next-Generation Hybrid Macro/Femto-cell Networks

Femto base stations are usually installed in the region of macrocells in next-generation hybrid macro/femto-cell networks, and the transmit power of macro base stations is much larger than that of femto base stations. Because the conventional handover decision is only based on the received signal strength (RSS), user equipments near the center of macrocells hardly camp on femtocells, even if th...
