Question 40

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

Wi-Fi technology is designed to provide wireless connectivity over a considerable range, typically up to 300 feet in open spaces, making it suitable for home and office environments.

A) Bluetooth

Bluetooth is a wireless technology designed for short-range communication, typically limited to distances of about 30 feet. While it is effective for connecting devices like headphones and smartphones, it does not support the range needed for the question.

B) Wide area network (WAN)

A wide area network (WAN) refers to a telecommunications network that extends over a large geographical area. It is not a specific wireless technology but rather a type of network that can encompass various technologies, including Wi-Fi, thus it does not directly answer the question about a specific wireless technology accommodating distances up to 300 feet.

C) Wi-Fi

Wi-Fi is specifically engineered to support wireless communication over distances up to 300 feet, particularly in optimal conditions. This range allows devices to connect to the internet or local networks without physical cables, making it the correct answer to the question.

D) Near field communication (NFC)

Near field communication (NFC) is a technology that enables short-range communication between compatible devices, typically working within a range of just a few inches. It is not suitable for distances approaching 300 feet, making it an incorrect choice in this context.

Conclusion

Wi-Fi is definitively the correct answer as it is specifically designed to accommodate distances up to 300 feet, unlike the other options which either have much shorter ranges or do not pertain to the same context of wireless technology. Understanding the distinct purposes and limitations of these technologies is crucial for identifying the right wireless solution for various needs.
