We present a new model for multiple input multiple-output (MIMO) out door wireless fading channels which is more general and realistic than the usual i.i.d. model. We investigate the channel capacity as a function of parameters such as the local scattering radius at the transmitter and the receiver, the distance between the transmit (TX) and receive (RX) arrays, and the antenna beamwidth sand spacing. We point out the existence of pinhole channels which exhibit low fading correlation between antennas but still have poor rank properties and hen ....etc

This paper compares and contrasts two technologies for delivering broadband wireless Internet access services:3G VS.WiFi. The former, 3G, refers to the collection of third generation mobile technologies that are designed to allow mobile operators to offer integrated data and voice services over mobile networks .The latter, WiFi, refers to the 802.11b wireless Ethernet standard that was designed to support wireless LANs. Although the two technologies reflect fundamentally different service, industry and architectural design goals, origins and ph ....etc

4G Wireless Systems

Abstract :

The ever-increasing growth of user demand, the limitations of the third generation of wireless mobile communication systems and the emergence of new mobile broadband technologies on the market have brought researchers and industries to a thorough reflection on the fourth generation. Many prophetic visions have appeared in the literature presenting 4G as the ultimate boundary of wireless mobile communication without any limit to its potential, but in practical terms not giving any design rules and thus any ....etc

WISENET is a wireless sensor network that monitors the environmental conditions such as light, temperature, and humidity. This network is comprised of nodes called motes that form an ad-hoc network to transmit this data to a computer that function as a server. The server stores the data in a database where it can later be retrieved and analyzed via a web-based interface. The network works successfully with an implementation of one sensor mote. ....etc

The convergence of three technology paradigms, viz. light-weight portable computers, the spread of wireless networks and services, and the ubiquitous Internet, aimed at allowing users the freedom to connect to the Internet at any time and in any place, to read email, query databases, retrieve information from the web or to entertain themselves, makes mobile computing a very promising prospect as well as a very formidable challenge. This paper details the mechanism of operation of Mobile IP network protocol, designed and developed to enable eff ....etc
