45. What is the name of the wireless technology that specifically accommodates distances up to 300 feet?

Answer: B

Explanation:

Wi-Fi is the wireless technology that specifically accommodates distances up to 300 feet.

Wi-Fi technology is designed to provide wireless networking capabilities over considerable distances, typically up to 300 feet, making it suitable for various applications in homes and businesses.

A) Bluetooth

Bluetooth is a wireless technology primarily designed for short-range connectivity, typically up to 30 feet. While it is effective for connecting devices like headphones and keyboards, it does not accommodate distances up to 300 feet, making it an incorrect choice.

B) Wi-Fi

Wi-Fi is indeed the correct answer as it is capable of supporting connections over distances of up to 300 feet, depending on the specific environment and router capabilities. This range makes Wi-Fi suitable for broader applications in larger areas compared to other wireless technologies.

C) Near field communication (NFC)

Near field communication (NFC) is a short-range communication technology that operates effectively only within a few centimeters. Given its extremely limited range, NFC cannot accommodate distances of up to 300 feet, rendering it an incorrect option.

D) Wide area network (WAN)

A wide area network (WAN) refers to a telecommunications network that extends over a large geographical area, but it is not a specific wireless technology like Wi-Fi. WANs can utilize various technologies, including wired and wireless methods, but do not specifically define a distance capability of 300 feet, making this option inaccurate in the context of the question.

Conclusion

Wi-Fi is the only option that accurately represents a wireless technology capable of accommodating distances up to 300 feet, which is essential for effective connectivity in larger spaces. All other options either operate at significantly shorter ranges or do not fit the definition of a wireless technology focused on that specific distance.
