Question 1

What is Wi-Fi (Wireless LAN)?

Answer 1

Wi-Fi, also known as Wireless LAN (WLAN), is used in laptops and mobile devices to connect wirelessly to home networks. It allows relatively slow to fast data transmission depending on the version.

Question 2

What are the characteristics of the 2.4GHz Wi-Fi frequency?

Answer 2

The 2.4GHz frequency offers larger coverage, better penetration of solid objects, lower data rates, more interference, and is often more crowded with devices.

Question 3

What are the characteristics of the 5GHz Wi-Fi frequency?

Answer 3

The 5GHz frequency provides smaller coverage, worse penetration of solid objects, higher data rates, less interference, and fewer devices use this frequency.

Question 4

What are mobile generations (3G, 4G, 5G, etc.)?

Answer 4

Mobile generations are the primary way phones access the internet, offering relatively fast connections, tunneling phone lines, and data transmission speeds dependent on signal quality.
