"Wi-Fi" na trademark of di Wi-Fi Alliance, wey dey restrict di use of di term "Wi-Fi Certified" to products wey don successfully complete interoperability certification testing.

Devices wey fit use Wi-Fi technology include personal computers, video-game consoles, phones and tablets, digital cameras, smart TVs, digital audio players and modern printers. Wi-Fi compatible devices fit connect to the Internet through WLAN and a wireless access point. Dis kind access point (or hotspot) get range of about indoors and a greater range outdoors. Hotspot coverage fit be as small as one room wey get walls wey block radio waves, or as large as many square kilometres wey dem fit achieve by using multiple overlapping access points.

Wi-Fi mostly dey use the UHF and SHF ISM radio bands. Because e no get physical connections, e dey more vulnerable to attack pass wired connections like twisted pair.

For 1971, ALOHAnet connect di Hawaiian Islands with UHF wireless packet network. ALOHAnet and di ALOHA protocol na early forerunners to Ethernet, and later di IEEE 802.11 protocols, respectively.

For 1985, one ruling by di U.S. Federal Communications Commission release di ISM band for unlicensed use. Dis frequency bands na di same ones wey equipment like microwave ovens dey use and dem fit dey subject to interference.```

Numbered questions: <response>: ```1. Wetin be one electronic device wey fit use Wi-Fi?
2. And anoda one?
3. And one more?
4. Wetin be hotspot?
5. Na only dis thing device need to get wireless internet?
6. True or False: Hotspot fit cover wider area indoors pass outdoors.
7. How small hotspot fit be?
8. How big hotspot coverage fit be if dem use multiple points?
9. You need license to use ISM band?
10. Wetin be kitchen device wey dey use the same band?
11. Which body decide to release the band for unlicensed use?
12. When e happen?
13. Wetin ALOHAnet be ancestor of?
14. Wetin be protocol wey ALOHA protocol give rise to?
15. Which area ALOHAnet serve?
16. When e happen?
17. Wetin be network wey e provide?
18. Wetin be type of wired connections?
19. True or False: Twisted pair dey more secure against attacks pass Wi-Fi.
20. Why Wi-Fi dey less secure?```
