Answer:
c. 120 feet
Step-by-step explanation:
WiFi can be defined as a wireless local area network that allows network devices such as access points (APs), computers (both laptops and desktops), smartphones, smart televisions, etc., to communicate with each other wirelessly over a short-ranged network. It is a standard communication network that uses radio waves to establish a channel (medium) between multiple network devices.
This ultimately implies that, the network range or distance covered by WiFi is largely dependent on transmission power and frequency. The standard range or distance covered by WiFi is about 50 meters (160 feet).
Hence, a WiFi traveling indoors in the form of radio waves and operating on the 2.4 GHz band would cover up to a distance of 150 feet. Also, a WiFi can reach or travel up to 300 feet outdoors.
In this scenario, the WiFi network Daniella is configuring in a restaurant for access by staff and customers can go as far as 120 feet indoors.
