Cellular Phone

by Metamaterial-embedded Low, Sar Pifa, M. R. I. Faruque, M. I. Hossain, N. Misran, M. Singh, M. T. Islam
"... Ametamaterial-embedded planar inverted-F antenna (PIFA) is proposed in this study for cellular phone applications. A dual-band PIFA is designed to operate both GSM 900 MHz and DCS 1800 MHz. The ground plane of a conventional PIFA is modified using a planar one-dimensional metamaterial array. The inv ..."

for Cellular Phone Applications

by R. Hattori, S. Suzuki, N. Ogawa, Y. Yamamoto, S. Miyakuni, T. Oku, H. Seki, T. Shimura
"... Abstract: Mass production of InGaP-HBT power amplifiers for cellular phones application in GSM and CDMA standards using a simplified device structure and process procedures are reviewed. The critical processes to realize high volume InGaP HBT production include a damage free SiN passivation by catal ..."

Melanoma Screening with Cellular Phones

by Cesare Massone, Rainer Hofmann-wellenhof, Verena Ahlgrimm-siess, Gerald Gabler, Christoph Ebner, H. Peter Soyer
"... Background. Mobile teledermatology has recently been shown to be suitable for teledermatology despite limitations in image definition in preliminary studies. The unique aspect of mobile teledermatology is that this system represents a filtering or triage system, allowing a sensitive approach for the ..."

Transactions on NFC Cellular Phones

by Jungha Woo, Abhilasha Bhagav-spantzel, Anna Cinzia Squicciarini, Elisa Bertino, Jungha Woo, Abhilasha Bhagav-spantzel, Anna Cinzia Squicciarini, Elisa Bertino
"... Abstract—A main challenge in mobile commerce is to make it possible for users to manage their transaction histories from both online e-commerce transactions and in-person transactions. Such histories are typically useful to build credit or to establish trust based on past transactions. In this paper ..."

Frequency assignment in cellular phone networks

by R. Borndörfer, A. Eisenblätter, M. Grötschel, A. Martin - IN ANNALS OF OPERATIONS RESEARCH , 1998
"... We present a graph-theoretic model for the frequency assignment problem in cellular phone networks. Obeying several technical and legal restrictions, frequencies have to be assigned to transceivers so that interference is as small as possible. This optimization problem is NP-hard. Good approximation ..."

Cellular Phones: Challenges and Opportunities

by unknown authors
"... Wireless telephones are rapidly replacing wireline tele-phones in many countries around the world. According to media accounts, a similar trend is taking hold in the United States. Although the truth is not quite as alarm-ing as the media reports suggest, the popularity of wire-less telephones and a ..."
