In many places all over the world rural and remote areas lack proper connectivity that has
led to increasing digital divide. These areas might have low population density, low …

Modeling forest propagation loss over a vast area is challenging, particularly for the hilly
terrain regions where canopy obstacle depth varies with region. To consider such vegetation …

Summary Nowadays, the popular 2.4‐GHz band is used in different systems, such as Wi‐Fi,
Bluetooth, wireless sensor systems, and wireless cameras. Instead of the over‐crowded 2.4 …

The rapid development of wireless technology compels to efficient use of frequency bands.
One possible way to achieve this goal is the cognitive radio (CR) systems, which allow a …

This paper discusses an analysis of Very High Frequency (203.25 MHz and 182.25 MHz)
signal strength measurement variation over a sizeable hilly-forested region in the northern …

Cognitive Radio (CR) is becoming a necessity for improving the spectrum use in the future,
as it provides efficient utilization of the available frequency bands by allowing unlicensed …
