Near field coupling can impact the performance of wireless communication systems by causing interference and signal degradation. This interference can lead to reduced signal strength, data errors, and overall decreased communication quality.

To understand how the wireless revolution and connectivity are related you need to understand the meaning behind them. The revolution is expected to dramatically affect the way we communicate and use computer technology. The connectivity is the capability to use information from the world beyond one's desk. This allows data and information to be sent over telephone or cable lines and through the air so that computers can talk to each other and share information. They are related because they are how we communicate or share this information. I hope this helps ~ Khristi Downing

Yes
sunlight affect land and water to due the heat.
fators that affect the quality of communication is the environment
WiFi is wire-less internet connection, and it provides connection to the internet on many computers at once. WiFi does not affect anything, except for the fact it provides internet to your computer, or other wireless devices.
Weather can and does affect computers and wireless signals. A thunderstorm, for instance, would produce a large amount of static "noise" to the signal, reducing the effective distance of the wireless equipment. Smoke would generally not have a noticeable on a signal, since it has no inherent radio properties, and is only slightly more dense than regular air, even if it is forming smog.
All or almost all materials affect wireless signals.
