establishing and operating private radio and television and its possible activity beside state radio and television is the selective method of administering radio and television in many countries worldwide. in legal system of iran, state run radio and television in article 44 of the constitution and interpretation of guardian council of mentioned article, establishing private radio and televisi...

This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...

Covid-19 was detected in Iran since February 2020, and until September 2020, all the provinces of the country were affected by this disease (1). During the Covid-19 pandemic, many older adults received a lot of stress and anxiety from the media and society, which caused them to become socially isolated and depressed. On the other hand, creating quarantine and social distancing as a policy adopt...

The industrial Internet of Things (IoT) is aiming to interconnect humans, machines, materials, processes and services in a network. Wireless Sensor Network (WSN) comprises the less power consuming, light weight and effective Sensor Nodes (SNs) for higher network performance. Radio Frequency Identification (RFID) and sensor networks are both wireless technologies that provide limitless future po...

the prevalent communications networks suffer from lack of spectrum and spectrum inefficiency. this has motivated researchers to develop cognitive radio (cr) as a smart and dynamic radio access promised solution. a major challenge to this new technology is how to make fair assignment of available spectrum to unlicensed users, particularly for smart grids communication. this paper introduces an i...

radio frequency identification (rfid) is used to identify the characteristics of an object wirelessly using radio waves. the purpose of this technology in this study is mainly focused on healthcare for inventory management and theft control replacing the manual logs. the storage and tracking of high-cost inventory items is developed. automatic reordering and billing interfaces are designed for ...
