Femtocells are low-power base stations to extend the cellular network coverage and provide high speed data service for indoor environments. To solve the severe interference problem introduced by unattached co-channel users, the interference mitigation technique, uplink attenuation, can be implemented at femtocell receivers. In this paper, we investigate the close-form outage probability function to...
The paradigm of wellness mobiles will enable health-care professionals to have access to comprehensive real-time patient data at the point of care and anywhere there is cellular network coverage. More importantly, users can continuously and frequently track their health on the go and receive real-time user assistance when needed to alter their lifestyles. Recently, there has been a growing interest...
Femtocells extend the cellular network coverage and provide high speed data service inside homes and enterprises for mobiles supporting existing cellular radio communication techniques. They also provide additional system capacity by offloading macro network traffic. This article reviews the characteristics of cdma2000-based femtocell systems. It discusses design and deployment aspects such as carrier...
This paper examines the issues of traffic load balancing in wideband code division multiple access (WCDMA) mobile communication networks through applying dynamic radio coverage. Dynamic radio coverage is achieved by adjusting radiation patterns of antenna arrays and the optimization of coverage is carried out cooperatively between cells using dedicatedly designed algorithm. In comparison with previous...
