We surveyed a pool of 433 students at the University of Banja Luka in Bosnia and Herzegovina during April 2010, examining users’ perceptions about mobile phones security. The main research hypothesis validated was that users are unaware of the nece

Free Space Optics (FSO) has the great potential for future communication applications. However, weather influenced reduced availability had been the main cause for its restricted growth. Among different weather influences fog plays the major role. A

In this paper, we present simulation results for the bit error rate (BER) performance and the fading penalty of a BPSK - subcarrier intensity modulation (BPSK-SIM) free-space optical (FSO) communication link in a log-normal atmospheric turbulence mod

Free Space Optics (FSO) links provide usage of high bandwidth and the flexibility of wireless communication links. However, weather patterns like fog and heavy snow fall limit the availability of FSO. Another technology providing similar properties r

The purpose of any communication system is to reliably transfer information between the source and destination. As a signal propagates through a wireless channel, it experiences random fluctuations in time, due to changes in reflections and attenuati
