Analysis of cellular systems where the base stations are placed at random compares the base station to mobile link in random systems to ideal hexagonal systems and shows how deployment costs and deployment speed can be greatly reduced.Abstract:
This paper analyzes cellular systems where the base stations are placed at random. Analysis compares the base station to mobile link in random systems to ideal hexagonal systems. Under log-normal shadow fading and sectorizing-but no channel planning-the random system has carrier to interference levels within 4 dB and spectral efficiency within 2 dB of the hexagonal system. A simple linear-time channel assignment algorithm reduces each of these differences by 1 dB. Thus, at a modest cost in performance, deployment costs and deployment speed can be greatly reduced.read more

Cellular performance bounds via shotgun cellular systems
TL;DR: The shotgun cellular system is introduced, a two-dimensional interference-limited cellular radio system that places base stations randomly and assigns channels randomly and indicates cellular performance is very robust and little is lost in making rapid minimally planned deployments.

Downlink Performance Analysis for a Generalized Shotgun Cellular System
TL;DR: In this article, the authors analyzed the signal-to-interference-plus-noise ratio (SINR) performance at a mobile station (MS) in a random cellular network, where the transmissions from each BS may be affected by random fading with arbitrary distributions as well as attenuation following arbitrary path-loss models.

Stochastic geometric modeling and interference analysis for massive MIMO systems
TL;DR: Stochastic geometric modeling of the BS and MS locations is used and closed-form expressions are derived for the distribution of signal-to-interference-ratio (SIR) for both uplink and downlink, showing that the downlink SIR is greatly influenced by the correlations between the pilot sequences in the non-orthogonal pilots case.

Carrier to Interference Ratio Analysis for the Shotgun Cellular System
TL;DR: This paper derives an analytical expression for the characteristic function of the inverse of the carrier-to-interference ratio and incorporates shadow fading into the SCS and demonstrates that it merely scales the base station density by a constant, hence, the cellular performance of theSCS is independent of shadow fading.

Analysis of Downlink Connectivity Models in a Heterogeneous Cellular Network via Stochastic Geometry
TL;DR: Using stochastic ordering, interesting properties and simplifications for the HetNet downlink performance are derived by relating these two connectivity models to the maximum instantaneous received power connectivity model and the maximum biased received power (MBRP) connectivity models, providing good insights about HetNets and their down link performance in these complex networks.

Universal digital portable radio communications
TL;DR: In this paper, the authors discuss limitations of the evolving approaches and consider objectives and approaches for providing more universal digital portable communications as an integrated part of telephone exchange networks, which can be accomplished by using demand-assigned radio links for the last thousand feet or so of telephone loops and sharing the remainder of the fixed distribution facilities.

Channel assignment for cellular radio using simulated annealing
TL;DR: The channel assignment problem, i.e. the task of assigning the channels to the radio base stations in a spectrum-efficient way, is an NP-complete optimization problem occurring during design of cellular radio systems and is solved using simulated annealing, which is a general approach to combinatorial optimization.
