Answer: Power P at distance 0.7 km is: 0.234 µW
Explanation:
We know that
inverse cube-power law.
Thus Power, P = c / d³
Substituting we have
15 µW = c / (175 m)³
c = (15 µW) x (175 m)³
Then finally Power value at 0.7 km.
Will be
P = c / d³
P = ((15 µW) x (175 m)³) / (700 m)³
= (15 µW) x (175 / 700)³
= (15 µW) x (0.25)³
=(15 µW) x (0.015625)
P = 0.234 µW
Answer:
The problems or risk when using a WiFi is that, hackers often have the ability to position themselves between the user and the end point connection. and once these hackers gains access to your information and privacy, u might lose important documents or contents.
It is of utmost importance that when an end user is using a public WiFi as a WAN, he/she must ensure to browse with VPN turned on, and the sharing options turned off.

The hacker also have access or privileges to every information you send out such as credit card information, emails and so on. once the hacker gains access to that information, you run into trouble.
