and threats that the mobile communication systems have. 1 Introduction Most distributed systems nowadays are still based on wireline communication. The computing devices are stationary and users connect to the network from a small, fixed set of points. This is about to change when mobile communication
MOBILE COMMUNICATION SYSTEMS
"... Abstract—In this paper we evaluate the potential of a 5-element monopole array incorporated into a handheld device for beamforming in the 5.0-GHz band. The geometry of the handset consists of a 5-element array: four elements located at the handset corners and the fifth-element located at the center. ..."

service has been dominated by voice communication. However, modern mobile communications systems are shifting their focus from solely voice communication to electronic mailing and Internet access. From now, we will evolve into a wireless multimedia society, where a combination of mobile communications
Mobile Agents in a Mobile Communications System Database
"... Future wireless communications systems will have to rely on a decentralized, scalable and redundant database infrastructure supporting flexible and evolving management strategies at different levels. In this paper, we claim that mobile agents are a promising approach to implementing such strategies ..."
