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.
An RF beam refers to a directed or focused radio frequency signal that is used for wireless communication or radar purposes. It is a concentrated stream of electromagnetic waves in the radio frequency spectrum. RF beams are often used to establish wireless connections over long distances with high accuracy and signal strength.
The geographical area that an antenna or wireless system can reach is known as its coverage area. This refers to the range or extent of the signal that can be transmitted and received by the antenna or system. The coverage area can vary depending on factors such as the power of the signal, the height and placement of the antenna, and the obstacles or interference in the environment.
Attenuation typically occurs in processes involving the weakening or reduction of a signal's strength, intensity, or energy. In communication systems, attenuation can happen in transmission lines, optical fibers, or wireless channels, leading to signal loss or degradation over distance. It is essential to account for attenuation to maintain signal quality and integrity in various applications.
When the nerve impulse encounters a myelin-covered section of a neuron, it jumps between the nodes of Ranvier, allowing for faster transmission speed due to saltatory conduction. Myelin acts as an insulator, preventing the impulse from dissipating and increasing the efficiency of signal transmission along the neuron.

It you can pick up Internet signal without hooking an ethernet cord into your computer. You can get the wireless signal in the wireless routers range.
You could attach an external directional antenna. Google for 'wireless antenna'.
No, With most wireless cameras; they rely on a wireless routers signal to work.
Stop HACKING!!
A wireless repeater is simply a device that receives wireless signals and repeats the signal to extend the distance the wireless signal can travel. The end result is that devices can be used further away from the wireless router.
According to Life123.com, "If you're experiencing wireless signal issues, you can always add a wireless signal amplifier. An amplifier connects to your wireless router and boosts the signal output, typically by connecting to where your antenna connects. Wireless signal amplifiers also boost the receiving capabilities of your wireless router, ultimately increasing your network speed and ensuring that you never lose signal." You can buy them here (see related links).
The strength of a wireless security camera's signal would depend on the camera in question. Some of the wireless security cameras are said to be about 900 mhz.
If you do not see signal from your router, it means that the signal is not strong enough an you need to get a wireless extender or a better router.

This a location that "broadcasts" wireless signal. Some fast food restaurants for example offer free "wifi", which is wireless signal for customers to use while they dine at the restaurant.
It has an access point which transmit signal to the client and receive.
