List and explain the main harmful effects in a wireless communication system. Select two of these issues (e.g. noise, security,...) and describe what general approaches are followed to resolve them.
Main harmful effects experienced due to the emerging network of the wireless communication system in our surroundings and governance are as follows:-
1. Noise:
In today's world due to the increase in high-frequency signals of different bandwidth, Noise has become the main problem around. there are many types of noise firstly the cross-connection of bandwidths and the unwanted noise occurred in different devices and secondly the real noise of frequencies which arises the mental and stress problems in humans and also problems in other animals especially in birds. This noise also affects the growth of plants.
2. Security:
Due to the increase in the use of wireless connections, it becomes easy for hackers and other cyber agencies to get into the confidential information of government and private companies. Nowadays the military war is going to be outdated and going towards cyber race and cyberwar and this becomes the core point on the security issue of any nation or state. This can lead to any criminal act and corruption in systems.
3. Effects on fertility:
Electromagnetic radiation emitted from the phone make an adverse effect on sperm motility. on the continuous contact in Electromagnetic radiation to the human body, this will lead to a change in sperm count and quality and the changes can be seen in the statistics of the fertility rate in humans.
4. Effects on the human body:
Many diseases as mentioned in the WHO report are risk of cancer, increased eye stress, damage in DNA, Alzheimer's, and loss of appetite. By the increase in high-frequency signals around, it has an adverse effect on the human body and results in depression and several types of mental and stress-related diseases.
Steps to be taken to resolve the issues caused by a wireless communication system:
1. Noise:
Try to minimize the distance from the various electromagnetic radiation emitting devices like mobile towers, radio stations, electric power station, telephone exchanges, etc
The government should limit the use of mobile towers and radio stations and should instead focus on using the satellite-based services, this will minimize the high crowded frequencies around the mobile and radio stations.
2. Security:
This problem can be resolved by using the most secure networks and the work should be handled by experienced professional employees.
To overcome the attacks on data and to fasten the response, should promote the use of artificial intelligence and jammers to detonate the attack by an immediate effect.

Many times cholesterol is viewed as a molecule that has harmful effects on the health of one's cardiovascular system. Contrary to what many may believe, cholesterol is a very important molecule that serves a vital function within the cell membrane. Cholesterol most important role is in: The maintenance of the structure of the bilayer by increasing membrane permeability. The maintenance of the structure of the bilayer by decreasing membrane permeability. Providing the sole anchor point for membrane proteins...
