Radio is an ideal media for marketing fast moving consumer goods because it can reach wide targeted listener demographics in urban habitat. A large number of people listen to radio while commuting in urban areas and respond to the broadcast of various commercial messages. This study aims at analyzing the impact of radio advertisements on urban commuters towards buying behavior in retail stores ...

Channel properties influence the development of wireless communication systems. Unlike wired channels that are stationary and predictable, radio channels are extremely random and don’t offer easy analysis. A Radio Propagation Model (RPM), also known as the Radio Wave Propagation Model (RWPM), is an empirical mathematical formulation for the characterization of radio wave propagation as a functi...

A wireless network is realized by mobile devices which communicate over radio channels. Since, experiments of real life problem with real devices are very difficult, simulation is used very often. Among many other important properties that have to be defined for simulative experiments, the mobility model and the radio propagation model have to be selected carefully. Both have strong impact on t...

3D beamforming is a technique which allows the adaptation of the base station (BS) antenna downtilt per user equipment (UE). The selection of the appropriate downtilt depends on the propagation properties of the environment. This paper investigates the optimum downtilt angle in a typical nonline-of-sight (NLOS) urban outdoor environment. Therefore measurements with variable downtilt have been c...

We study through simulation the performance of two MANET routing algorithms in a realistic urban environment. The two algorithms, AODV and AntHocNet, are representative of two different approaches and design methodologies. AODV is a a reference state-of-the-art algorithm following a purely reactive approach. AntHocNet is based on swarm intelligence and integrates proactive and reactive mechanis...

Radio propagation simulation tools are important for prediction and verification of the radio signal coverage by individual transmitters or transmitter networks such as mobile phone cellular networks. In the case of a large geographic area with a relative high resolution, the simulation can become computationally demanding, taking a considerable amount of time to accomplish. Parallel processing...

We present a deterministic model of radio wave propagation based on radiance transfers. Our model uses radiosity techniques to determine facet-to-facet specular reflections according to a 3D building description. The model contains two main components. First, visibility between elements is determined and used to establish links that represent radiance transfers that include diffraction and free...

This paper investigates the affect of pathloss and mobility in an urban environment on MANETs. Specifically, this investigation employs mobility and pathloss that resembles the mobility of pedestrians and pathloss in urban environments. We study the behavior of MANETs on a university campus and in the Paddington area of London England. The model utilizes ray tracing to provide realistic radio w...

NTT DOCOMO is currently studying a fifth-generation mobile communications system (5G) intensely. This system is expected to use high frequency bands, so clarification of the propagation characteristics in these high frequency bands is the most important issue in radio propagation research for 5G. This article gives an overview of the issues and current state of study in radio propagation, and d...

This paper presents results of measurements campaign carried out at a carrier frequency of 24GHz with the help of TPLINK router in indoor line-of-sight (LOS) scenarios. Firstly, the radio wave propagation strategies are analyzed in some rooms with router of point to point Ad hoc network. Then floor attenuation is defined for 3 floors in experimental region. The free space model and dual slope m...
