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.

Bell Labs Technical Journal, 2007
This paper reviews the Alcatel-Lucent Universal Mobile Telecommunications System (UMTS) base station router (BSR)—a radio access network (RAN) and core network (CN) in a single network element. While typical cellular UMTS networks are built from a plethora of network elements and are maintained in a hierarchical fashion, the BSR combines all functions ...

2016 International Conference on Control, Instrumentation, Communication and Computational Technologies (ICCICCT), 2016
A weather station can be described as an instrument or device, which provides us with the information of the weather in our neighbouring environment. For example it can provide us with details about the surrounding temperature, barometric pressure, humidity, etc.

Advanced base station technology
IEEE Communications Magazine, 1998The authors present an overview of advances in three areas including software radio, adaptive antenna technology, and high-temperature superconductivity as currently envisioned for use in advanced cellular base stations. The conclusion broadly drawn is that the advancement in DSP and ASIC technologies will provide the major contribution in making these

Synchronization of R-Mode Base Stations
2020 Joint Conference of the IEEE International Frequency Control Symposium and International Symposium on Applications of Ferroelectrics (IFCS-ISAF), 2020R-Mode is an alternative maritime PNT technology currently under development. It is based on synchronous transmissions and multilateration. Base station synchronization errors are recognized as the major error source. Introduction to R-Mode using maritime radio beacons, timing requirements, and the concept of R-Mode in-band synchronization are briefly ...

The hydrogen for base radio stations
INTELEC 07 - 29th International Telecommunications Energy Conference, 2007In this paper possible solutions for the energy supply of telecommunication systems (both TV broadcasting and Base Radio Stations for mobiles) have been studied, taking into account the consumption profiles of the units and the most suitable solutions to optimise the system from the points of view of environmental impact, cost, reliability and safety ...

Radio base stations in the cloud
Bell Labs Technical Journal, 2013During the past few years, architectures for cellular radio networks like 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) have evolved towards flatter topologies with fewer centralized nodes, shifting more and more radio-related processing towards the base station or even further into so-called remote radio heads near the antennas ...

LTE Base Stations Localization
2014Direction-of-arrival (DoA) estimation algorithm for LTE base stations (BSs) is proposed in the paper. The algorithm is assumed using of mobile receiver station (MRS) with antenna array and is based on the analysis of peaks of cell-specific reference signal (CRS) autocorrelation functions (ACFs).
