The ever increasing use of cellular phones and the increasing number of associated base stations are becoming a widespread source of nonionizing electromagnetic radiation. Some biological effects are likely to occur even at low-level EM fields. In this study, a gigahertz transverse electromagnetic (GTEM) cell was used as an exposure environment for plane(More)
It is expected that drones will take a major role in the connected smart cities of the future. They will be delivering goods and merchandise, serving as mobile hot spots for broadband wireless access, and maintaining surveillance and security of smart cities. However, pervasive use of drones for future smart cities also brings together several technical and(More)
In this paper, we consider the use of device-to-device (D2D) communications for extending the coverage area of active base stations in the case of public safety communications with partial coverage. A 3GPP standard compliant system level simulator is developed for D2D and heterogeneous network (HetNet) technologies considering public safety scenarios. The(More)
In this paper, experimental results with software defined radios (SDRs) for capturing and localizing WiFi and GSM users are developed. First, a detailed overview on various SDR equipment and software, such as embedded and networked USRPs, WiFi Pineapple, GNU Radio, OpenBTS, and Wireshark is presented. Sufficient details are provided on how to configure and(More)
