We address the problem of fair assignment of base station locations in a cellular network. We use the generalized α-fairness criterion, which encompasses the different notions of fairness: that of global, proportional, harmonic or max-min fairness in our study. We derive explicit expression for α-fair BS locations under ’large population’ limits in the case of simple 1D models. We show analytic...

RF power amplifiers in mobile WiMAX transceivers operate in an inherently nonlinear manner. It is possible to amplify the signal in the linear region, and avoid distortion, using output power back-off; however, this approach may suffer significant reduction in efficiency and power output. This paper investigates the use of Doherty techniques instead of back-off, to simultaneously achieve good e...

Most inherently distributed systems require self diagnosis and on-line monitoring. This is especially true in the domains of power transmission and mobile communication. Much effort has been expended in developing on-site monitoring systems for distributed power transformers and mobile communication base stations. In this paper, a new approach has been employed to implement the autonomous self ...

The mobile telephone companies are currently rolling out their GSM communications systems throughout Devon. Several people have asked me to write a discussion of the latest research on health problems associated with base stations. This is of particular concern to Devon people because of the highly publicised cancer clusters around the Orange transmitter in Crediton and the shared transmitter i...

Wireless networks with movable base stations combine the advantages of mobile ad hoc networks and wireless LAN to achieve both flexibility and scalability. We present the hierarchical mobile wireless network (HMWN) to support movable base stations. HMWN may be applied to ad hoc networks as well to build a virtual hierarchy. In such a system, mobile hosts are organized into hierarchical groups. ...

This paper proposes an algorithm for the identification of the minimum cost solution over a 10 year time horizon to power an LTE (Long-Term Evolution) macro base station, using a photovoltaic solar panel, a set of batteries, and optionally also a secondary power source, which can be a connection to a (possibly unreliable) power grid, or a small Diesel generator. The optimization is formalised a...

The energy consumption of home femto base stations (BSs) can be reduced, by turning off the Wi-Fi radio interface when there is no mobile station (MS) under the coverage of the BSs or MSs do not transmit or receive data packet for long time, especially in late night. In the energy-efficient home femto BSs, if MSs have any data packet to transmit and the Wi-Fi radio interface in off state, MSs w...

The location of mobile users served by cellular networks is considered. The chosen approach assumes that location is estimated through angular triangulation with three base stations (BSs). New estimates are proposed, which are described by closed-form expressions, and are alternatives to the maximum likelihood estimate. It is shown that the accuracy of the estimate coinciding with incircle cent...
