“…In an experiment described in [7], a group of users were given a test tool to allow them to compare the coverage quality of their macrocell provider with and without a residential small cell. For both UMTS and CDMA2000 high-speed data services (HSDPA and 1xEV-DO, respectively), users on average experienced close to five times improvement in physical layer data rate using a small cell when the measurements were averaged across the entire house.…”

“…Many wireless operators now depend on this emerging technology to provide the more ubiquitous coverage necessary for high-speed data and voice applications. Small-cell technology has rapidly evolved over the past few years from the research and standardization phase described in [3], [7], and [13]- [20] to commercial network deployments with several million installed units around the globe.…”

This paper describes the architectures of current and next-generation residential small-cell networks, and how these large networks are effectively provisioned and managed.ABSTRACT | In the last few years, small-cell technology has moved from the realm of academic research to large commercial networks with millions of deployed units. This paper discusses the challenges in deploying and maintaining a largescale residential small-cell network. The paper first discusses the need for residential small cells to provide ubiquitous coverage in homes located in poor coverage areas of the conventional macrocell, and then describes the architectures of current and next-generation residential small-cell networks, and how these large networks are effectively provisioned and managed. The paper is air interface agnostic and is based on the experience of the authors in commercial deployment of both UMTS and CDMA2000 femtocell networks.

“…Overall throughput for different scenarios has been presented in [1] and [4] and a comparison between open and closed access is presented in [2]. Data rates for indoor users served by macrocells and femtocells are compared in [5]. Interference management based on power control and performance in terms of capacity and coverage statistics (outage) is presented in [6].…”

In this paper we analyze how femtocell base stations (FBS) cause interference in the receivers of user terminals connected to macro base stations. A coverage hole around a FBS appears when closed access strategies are used, i.e. when only authorized users can access the FBS, and when the FBS shares the same or a portion of the macrocell frequency channel. At the cell borders of a macrocell the coverage holes can be large, especially for indoor users (10 -30 m radius for the investigated cases). The coverage holes can be reduced if different frequency channels are allocated for macrocell and femtocell operation, e.g. down to 1 -2 m for WCDMA femtocells in adjacent channels. When separation in frequency is not feasible, dynamic channel allocation (OFDMA) or adjustment of the FBS transmission power can be used to reduce the coverage holes. However, the different dynamic strategies have drawbacks in the form of reduced FBS performance and increased system complexity.Operators should consider open access schemes when using cochannel operation.

“…Presently, broadband data services have become an increasingly significant source for mobile operators' businesses [1]. Such broadband services require much higher data throughput performance than the traditional voice services to meet the end users' quality-of-service (QoS) requirements, which bring challenges to the existing cellular wireless infrastructure [2].…”

User association for energy harvesting relay stations in cellular networks

We consider a cellular wireless network enhanced by relay stations that are powered by renewable energy sources. Such a network consists of the macro base stations (BS), relay stations (RSs), and many mobile stations (MSs). In addition to the traditional data/voice transmission between the BS and the MSs, a higher service tier may be provided by using the energy harvesting RSs for some MSs. We propose a network scenario utilizing the energy harvesting relay stations to improve the service quality without taking the additional licensed frequency band and transmission power, and design a user association algorithm for the energy harvesting RSs in such a network. The goal is to assign each MS an RS for relaying its signal to minimize the probability of the relay service outage, i.e, the probability that an MS's relay service request is rejected. First, we propose a network scenario and develop a mathematical model to estimate the rejection probability for a given user association. We then propose a low-complexity local search algorithm, which balances the computational complexity and the performance, to obtain a locally optimal user association. Simulation results are provided to demonstrate the superior performance of the proposed techniques over the traditional methods.
