“…E.P. Agbo et al 14) studied experimentally quality of VHF, UHF and SHF and its dependency on refractive index variation with (Climate) temperature and (water) humidity. The temperature of atmosphere and its humidity changes throughout the year in every place and thus causes changes in quality of radio waves propagates through it.…”

In the field of telecommunication, network planning plays an important role to maximize the system performance and it is very much related to received signal strength (RSS). While transmitting signal from the transmitter to the receiver, signal has to face so many obstacles like varying environment conditions, high-rise buildings, dense forests etc. Signal strength gets affected with varying distance between the transmitter and receiver too. So for efficient network planning, information about the effect of all these parameters on received signal strength (RSS) should be known to us. So this study aimed to investigate the variation in Received Signal Strength for LTE signal (RSSLTE) with respect to the variation of four input parameters i.e. Relative humidity (25 % to 75 %), Temperature (12 °C to 48 °C), Air quality index for Particulate Matter 2.5 (50 to 500) and Distance from the base station (98 m to 300 m). Optimization of received signal strength was also carried out by using response surface methodology. Optimum value of received Signal Strength for LTE signal (RSSLTE) was found to be -87.0393 dBm when the input parameters i.e.

“…Adopting these alternative energy resources can go as far as creating jobs, improving energy access and security [5], and reducing the emission of fossil fuels, which depletes the ozone layer and contributes to the formation of GHGs; this ramps up the average global surface temperature. Studies by Agbo et al [6,7], Agbo and Ekpo [8], Agbo [9], and Alhaji et al [10] have shown that the ambient temperature for their respective study locations in Nigeria is steadily increasing. This shows the importance of adopting clean, renewable energy.…”

“…Variations of meteorological parameters affect the amount of energy gotten from the sun. According to studies from Agbo et al [6,7], Agbo and Ekpo [8], Agbo [9] Alhaji et al [10], and Akinbami [11], climate change is one of the effects of these variations with its issue resulting from diverse anthropogenic activities. With the recent increase in cellular networks' deployment across the world and the most recent introduction of the 5th Generation (5G) technology, two main problems have been noticed; the cost of energy for running these mobile networks and its effects on the environment.…”

“…Climate, usually defined as the "average weather," is more rigorously, defined in terms of the mean and variability of relevant quantities over a period ranging from months to thousands or millions of years [1,2]. The classical period is 30 years, as defined by the World Meteorological Organization (WMO) [1].…”

Background: Every century has its own public health challenge. Climate change is the present century's challenge. There are various health risks arising from climate change which without mitigation actions, will tend to worsen with each passing day. Study Aim and Objective: To study the knowledge of health impact of climate change and practice of appropriate preventive measures among students of a Nigerian Tertiary Institution Methodology: A descriptive cross-sectional survey was carried out using structured questionnaires. These questionnaires were shared randomly among students from five selected departments in the college of health science and data was analyzed using SPSS Version 20.0 Results: It was found that all the students were aware of climate change and 91.7% knew about the effect of climate change on health. Significantly 78.7% believed that climate change was from man-made causes but surprisingly only 34.3% were taking actions in mitigating the effect of climate change. Conclusion: Despite the high knowledge about climate change, majority of actions taken by the students were just for convenience and to save money, not necessarily because they wanted to prevent the effects of climate change on health. Recommendation: Government and Non-governmental organizations should form advocacy clubs for young students as a platform to sensitize them on climate change and its effects. There is need to introduce rewards and sponsorships for individuals who successfully learn about climate change and ways to mitigate its effect on health.
