Radio Propagation in Outdoor Sub-Urban Environment:Effect on Gsm Signal Strength
In mobile communication, the cell phone needs adequate signal strength to properly place or receive calls. Signal strength varies based on location and multipath is one of the conditions that lead to signal variation in a given environment. In this paper, measurement of signal strength with increase in distance was made at two different environments. The plot of signal strength relative to median against distance revealed more random variation at location A suggesting the presence of multipath in that environment. It was also observed that in a real world environment with obstructions, shadowing can lead to loss of more than 13dBm signal strength.
