With the rapid growth of the Internet, traditional broadcasters are under severe pressure from their competitors. In order to enhance their competitiveness, broadcasters need to provide not only traditional linear broadcast services but also new tri-play services. Traditional terrestrial broadcast systems need to be upgraded to next generation broadcast wireless (NGB-W) systems, where terrestrial...
The use of centralized signal processing for dense urban mobile networks is gaining interest both in research and in industry. Gathering most of the base station functionalities in a processing pool would enable capacity sharing and the implementation of advanced techniques such as coordinated multi-point. Nevertheless, this puts stringent requirements on the network interconnecting the processing...
The future AN is envisioned as an IP-based hierarchical network with heterogeneous nodes and waveforms. Due to its highly dynamic nature and bandwidth constraints, new AN technologies are needed to provide reliable network operations with similar levels of mission support as in terrestrial networks. This article first identifies challenges in designing and evaluating AN technologies and then describes...
Wireless Sensor and Actuator Networks (WS&AN) currently face their actual deployment challenges. Simple point-to-point RF communications metrics remain focused on active modes peak power consumption and communication duty cycles. But, once RF links have to set themselves into mesh networks, complex interactions between RF nodes arise and various metrics must be taken into account. Here starts...
The increasing usage of mobile data-intensive applications and their needs for high data rates are setting challenges towards the today's wireless mobile communication systems. The Third Generation Partnership Project (3GPP) has addressed these challenges by introducing an IP-based Long-Term Evolution (LTE) project based on Orthogonal Frequency Division Multiple Access (OFDMA) technology, aiming to...
Some applications require that the communication link between the master and slave transceivers be maintained for a certain lifetime and be recovered as soon as possible whenever the link is broken. In these cases especially for mobile applications, it is most important to reduce the power consumption for both communication. While the master and slave are in linked status, neither of the receivers...
One of the many important parts of any multi-participant quiz game show is the Player Selection System. All participating groups are equipped with a selection button placed in front of them which can be used by them to give a response. The Player Selection System determines the group that gives the first response. Many of these systems used today are wired systems that consume a considerable amount...
The paper presents some of the problems that a mobile communication system for data transmission in a public transport management system has to work with. The mobile WiFi communication operating in a busy urban area, problems in connection with the EMC of the other vehicle's equipment and the management of the data transmission are taken into account.
The FlexNet-Waveform (FN-WF) is a new, highly-configurable MANET waveform for the international ground-based SDR arena, designed for the new FlexNet-One and FlexNet-Four hardware platforms. To ensure maximum compatibility and interoperability, the FN-WF assumes an IP-based platform with standard COTS protocols on the wired, Ethernet connections, while the wireless links utilize the best practices...
There are a very wide range of application prospects in various industries that integrating RFID technology into mobile communication terminals. This paper presents NFC mobile phone system solutions as well as the radio frequency module identification solutions of NFC mobile phone. The achievement of this technology will bring great convenience to people's lives.
In this paper we present a concept for a test system, that can establish an IP connection over NFC. Any further IP data traffic is then tunneled through a wireless NFC link. Besides a short introduction about the NFC technology, this concept is described in the first part of the paper. This system has been realized with two NFC boards, each equipped with an NFC radio chip, and was tested on its performance...
Sensor web which is called new trend of nowadays, the development of wireless network environment and minimization of sensor make practical monitoring on physical environment possible. Sensor is being a clear technical trend which autonomously senses increase of usefulness on access of wireless and mobile network, and distributed network. Therefore, Web-service which is about sensor network including...
