Abstract Purpose of this paper: The objectives of this paper are two folds: (1) utilizing hierarchical fuzzy technique for order preference by similarity to ideal solution (TOPSIS) approach to evaluate the most suitable RFID-based systems decision, and (2) to highlight key risks and benefits of radio frequency identification technology in healthcare industry. Design/methodology/approach: R...

Computer aided design and computer aided modeling tools are becoming increasingly important in the design and performance evaluation of communication systems. In this work, we report on the computer simulation modeling study of terrestrial digital microwave radio transmission, using Block Oriented System Simulator package (BOSS). The work concentrates on semi-analytical error rate evaluation in...

A few years ago it was recognized that the vision of a truly low-cost, low-power radio-based cable replacement was feasible. Such a ubiquitous link would provide the basis for portable devices to communicate together in an ad hoc fashion by creating personal area networks which have similar advantages to their office environment counterpart the local area network (LAN). Bluetooth is an effort b...

the types of transmission systems which today are available for long distance transmission of large numbers of telephone circuits are those for coaxial cables and radio links. the number of circuits is increased in both cases in step with development in technique. radio links have for several years been able to transmit 600 telephone circuits per system. and are now being designed for 960 circu...

a typical radio frequency identification system (rfid) includes one reader and a number of tags. the reader transmit to commands to the tags with interrogation radio signals, and tags receive the command and then respond with their identification. readers with interrogation signals can read tags’ responses. in rfid systems, when multiple tags respond to one reader simultaneously, tag collision ...
