Optimization of the Assignment of Base Stations to Base Station Controllers in GERAN
IEEE Communications Letters, 2008In GSM-EDGE radio access network (GERAN), the assignment of base stations to base station controllers has a strong impact on network performance. In this paper, an exact method is proposed to improve an existing assignment of base stations to base station controllers. The aim is to minimize the number of handovers between base station controllers given

User-Base Stations Association in Multi-Tenant Base Station Networks
GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017Multi-tenant BS (MBS) is a new architecture to improve network capacity in which a single BS is tenanted to multiple operators. MBS allows multiple tenants to transmit from a single BS by using their own spectrum resources, resulting in a closer proximity to UEs.

Scientific American, 2005
This article focuses on the use of airships to provide Wi-Fi broadcasting. Park an antenna high in the stratosphere and then relay signals to and from devices below. Such an airborne transceiver could blanket urban areas with wireless coverage more cheaply than satellite-based alternatives while avoiding the need to build forests of mast-mounted base ...

Health Effects of Base Stations [PDF]
, 2006 Mobile phones and their base stations transmit and receive signals using electromagnetic waves. In this study, effects of RF radiation from mobile phone base stations on human health have been examined extensively. Researches and international regulations in this matter are compared with the measured values in Turkey in order to make it clear if base ...

Synchronization of cooperative base stations
2008 IEEE International Symposium on Wireless Communication Systems, 2008We consider synchronization techniques required to enhance the cellular network capacity using base station cooperation. In the physical layer, local oscillators are disciplined by the global positioning system (GPS) and over the backbone network for outdoor and indoor base stations, respectively. In the medium access control (MAC) layer, the data flow

Base station location optimization
Gateway to 21st Century Communications Village. VTC 1999-Fall. IEEE VTS 50th Vehicular Technology Conference (Cat. No.99CH36324), 1999Optimal base station location involves locating multiple base stations within a specific deployment site, while providing an acceptable quality of service to mobiles. Published research has focused on the objective function formulation and local optimization strategies.
