Abstract
For the network planning in the field of telecommunication networks received signal strength plays an important role. The received signal strength gets affected due to the varying environment condition through which the signal propagates and it also depends on the distance between the location of signal transmitter and the receiver. So complete information about these parameters are very much requires for proper mobile network planning. By keeping all these challenges in mind, this study was aimed to determine the received signal strength for Long-Term Evolution (LTE), Second Generation (2G) and Third Generation (3G) wireless technologies with challenging environment conditions. All the experiments were conducted at Lajpat Nagar residential area which is located in New Delhi. During the experiments received signal strength for all the three above mentioned wireless technologies were monitored with respect to varying environment conditions (Temperature, Relative Humidity and Air quality index for Particulate Matter 2.5) and distance from the base station. Later the optimization of received signal strength was carried out by using response surface methodology. Measurement results showed that Second Generation (2G) signal strengths was significantly higher than Third Generation (3G) and Long-Term Evolution (LTE) and the best values obtained for received signal strength for Long-Term Evolution (LTE), Third Generation (3G) and Second Generation (2G) were -77.9264dBm, -60.0345dBm and -58.1280dBm respectively. ANOVA results shows good mathematical modeling between input and output responses.
