Spectrum Pooling for Next Generation Public Safety Radio Systems



INTRODUCTION
Dynamic Spectrum Access (DSA) technologies, including
Cognitive Radio (CR) technologies, are in development for the
next generation of commercial, military, industrial and public
safety networks. These technologies hold the promise of more
flexible and adaptive radio architectures, capable of sharing
the RF spectrum much more intensively than is feasible with
today’s currentl ....etc

Design and Application of Radio Frequency
Identification Systems

Abstract

The recent world, development of effective technologies for linking the object
wireless information is being prompted in various fields. Radio frequency identification
(RFID) is the latest technology for automatic identification which allows the transmission
of a unique serial number wirelessly. The purpose of this paper is to review RFID systems
and its various components infrastructure. The components and features are still under
research and b ....etc

1.1 Wireless Communication Systems
Wireless communication has experienced tremendous growth in the last decade. In
1991 less than 1% of the world’s population had access to a mobile phone. By the
end of 2001, an estimated one in every six people had a mobile phone . During the
same period the number of countries worldwide having a mobile network increased
from just three to over 90%. In fact the number of mobile subscribers overtook the
number of fixed-line subscribers in 2002, as shown in Figure 1.1. It is predicted that
th ....etc

Abstract

This paper presents a demandbased engineering method for designing
radio networks of cellular mobile communication systems
The proposed procedure is based on a forwardengineering method the Integrated Approach to cellular network planning and is facilitated by the application of a new discrete population model for the trac description the Demand Node Concept
The use of the concept enables the formulation of the transmitter locating task as a Maximal Coverage Location Problem MCLP which iswell known in economics fo ....etc

Vision for Beyond 4G Broadband Radio Systems




INTRODUCTION

Mobile communication experienced a tremendous success,
ever increasing availability and performance of mobile
services, starting with voice but recently expanding into
various data services. This trend is expected to accelerate due
to increasing popularity of smart phones, super phones and
tablets with powerful applications and multimedia capabilities
up to pervasive 3D multimedia an ....etc

Title: cognitive radio systems

Abstract

Efficient use of radio spectrum is a necessity for future wireless systems. While the vast majority of the frequency spectrum is licensed to different organizations, observations provide evidence that usage of the licensed spectrum is by far not complete

neither in the time domain nor the spatial domain. This material discusses basics of Cognitive radio (CR), classifications of

cognitive radio systems, cognitive system architecture, antenna design for cognitive radio system.
