The deployment of aerial base stations (ABSs) mounted onboard unmanned vehicles is emerging as a promising technology to provide connectivity in areas where terrestrial infrastructure insufficient or absent. This may occur, for example, remote areas, large events, emergency situations, affected by natural disasters such wildfires tsunamis. To successfully materialize this goal, it required that...

As a result of dense installations of public mobile base station, additional electromagnetic radiation occurs in the living environment. In order to determine the level of radio-frequency radiation generated by base stations, extensive electromagnetic field strength measurements were carried out for 664 base station locations. Base station locations were classified into three categories: indoor...

In [1] a rate-compatible joint network-channel code (JNCC) for the two-way relay channel was proposed which can be applied for the cooperative uplink and downlink in a mobile communication system with the help of a relay. We assume the system model of [1] and present an improved JNCC which is based on the decode-and-forward scheme of [2]. In [2] a coding scheme was proposed which does not consi...

This paper addresses the displacement of a base station with optimization approach. A genetic algorithm is used as optimization approach. A new representation that describes base station placement, transmitted power with real numbers, and new genetic operators is proposed and introduced. In addition, this new representation can describe the number of base stations. For the positioning of the ba...

In this paper, Wireless sensor networks place sensors into an area to get data and send them back to a base station. Data fusion, in which collected data are fused before they are sent to the base station, is usually implemented over the network. Since a sensor is typically placed in locations that are accessible to malicious attackers, information assurance of the data fusion process is very i...

This white paper is concerned with connectivity between functional units within conventional and evolved wireless base stations. In-phase/quadrature (I/Q) radio sample distribution between the baseband and radio modules is addressed, as well as internal transport of traff ic and control data within the base station. The white paper is organized as follows: • The Introduction section provides a ...

A beamforming algorithm, the Conjugate Gradient, is applied to a base station array, in the up-link, for UTRATDD. Micro-cell, street type, propagation scenarios are considered, using a Wideband Directional Channel Model. Groups of mobile users are placed at different distances from the base station, along the street axis. The average beamforming gain is analysed, varying the number of array ele...
