Layer Reassignment for Antenna Effect Minimization in 3-Layer Channel Routing


Abstract

As semiconductor technology enters the deep submicron em, reliability has
become a major challenge in the design and manufacturing of next generation
VLSI circuits. .ln this paper we focus on one reliability issue - the antenna
effect in the context of s-layer channel routing. We first present an antenna effect
model in Z-layer channel routing and, based on this, an antenna effect cost
function is proposed. A layer ....etc

THE IMPACTS OF ANTENNA AZIMUTH AND TILT INSTALLATION ACCURACY
ON
UMTS NETWORK PERFORMANCE


Abstract

Inconsistencies in setting up antenna azimuth and tilt during installation may reduce overall network performance. However, the degree of quality degradation depends on the amount of the discrepancy between the designed and installed parameters. The paper invest ....etc

Universal Mobile Telecommunication System (UMTS) is one of the third generation (3G) mobile phone technologies. It uses WCDMA as the underlying standard and is standardized by the Third Generation Partnership Project (3GPP) and represents the European answer to International Telecommunication Union’s (ITU) International Mobile Telecommunication 2007 requirements for 3G cellular radio systems. UMTS is sometimes marketed as 3GSM, emphasizing the combination of the nature of the technology and the GSM standard, which it was, designed to succ ....etc

Abstract
The next generation of mobile/wirelesscommunication systems is expected to includeheterogeneous broadband wireless networks that willcoexist and use a common IP core to offer a diverserange of high data rate multimedia services to endusers with contemporary mobile devices that areequipped with multiple network interfaces since thenetworks have characteristics that complement eachother. This requires the provision of seamless verticalhandoff. This paper provides components of anadaptive multiple attribute vertical handoff decis ....etc
