“…There is a strong demand for large transmission capacity as a result of unprecedented growth in data traffic, statistical reports show that mobile traffic is expected to grow 66 times more before the end of this decade [1], while the widespread use of micro cell wireless systems with corresponding limited frequency resources has led to inter cell interference [2]. Wireless communication are becoming routinely used by over 500 million consumers for a large variety of applications such as data transfer, internet access, audio and video streaming, and social networking.…”

The success of radio wave propagation in a building is affected by the topology, construction and materials of the building. UWB wireless communication is highly desirous and extensively engage by subscribers for real time applications due to its huge bandwidth potential with capability to deliver high data rate transmission. The impact of the properties of building materials on the way of Propagation at this frequencies calls for attention of the stakeholders, otherwise seamless transmission desired will be compromised and distorted. high frequencies are subject to rapid attenuation in presence of lossy materials like cement and glass which are the constituents of building where such transmission links will be deployed. This paper examines the effects of various building materials on wireless signals propagation at millimetre waves spectrum bands at 24GHz using Ubiquity airFibre 24GHz in indoor environment. A direct field strength measurement was used for this work, the results show that building materials have a significant effect on the wireless signal at this spectrum band.

“…Network model evaluation and testing are essential in improving various new wireless and heterogeneous communication technologies [1][2][3][4] and their deployment in the real world [5][6][7][8]. Evaluation and test of a network model generally can be classified into two major types: physical test approach and simulation test approach [9].…”

Abstract-Network simulators, e.g., QualNet, have been widely used for the sake of cost efficiency in network model evaluation and testing. In order to evaluate and test the impacts of parameters on network models, massive simulations and result analysis are typically running repetitively in a sealed virtual environment per a non-real-time simulated clock, apart from real-time human interactions. The major drawback of this caustic approach is obvious in large-scale network simulations with long simulation time and hardware-in-the-loop accessories, when the result analysis must be adaptive to human factors in nowadays computer networks. In this paper, we design and implement an interactive real-time user interface (RTUI), which is a reliable human-in-the-loop framework that allows human users to dynamically modify the parameters of network model during the simulation process. With negligible delays and overhead, the impacts of parameter changing on network model can be actualized and measured at real time, rather than in a repetitive manner of the conventional approach, resulting in RTUI's time-efficiency and cost-efficiency in network protocol debugging and assessment.

“…Multimedia services requirements nowadays encompass not only large bandwidths, but also on-the-move facilities. Future 4th generation wireless communications systems will provide seamless mobility support to access heterogeneous wired and wireless networks (Makhecha & Wandra, 2009), (Lin et al, 2010 In this way, a mobile user can seamlessly switch between different networks, supporting the same services. This process must be performed to automatically adapt to change access networks and environments, without any user participation.…”
