Step-by-step explanation:
A limited geographic area that provides wireless access for the public is known as a Wireless Hotspot. These hotspots enable devices like smartphones, laptops, and tablets to connect wirelessly to the internet via WiFi, which is facilitated by a wireless router exchanging data over the internet. WiFi operates on microwave frequencies in the range of 2.4 GHz to 5.0 GHz, allowing for compatibility across various devices and manufacturers. The Federal Communications Commission (FCC) oversees all forms of telephony, including wireless, and has been involved in efforts to address the digital divide, such as opening up wireless 'white spaces' to improve access to high-speed internet.
