In the context of wireless communication technology, consider the following statements:
1. Wi-Fi 5 is Target Wake Time (TWT) technology which allows devices to ‘sleep’ when they are not in use.
2. Wi-Fi 5 uses the 5GHz band frequency to deliver high throughput in wireless local area networks (LANs).
3. Wi-Fi 6 allows Wi-Fi 5 devices to connect, even if older devices don't support Wi-Fi 6.
Which of the statement(s) given above is/are correct?
(a) 1 only
(b) 2 and 3 only
(c) 1, 2 and 3
(d) 2 only
Explanation Statement 1 is not correct: Target Wake Time (TWT) is a feature of Wi-Fi 6 (802.11ax), not Wi-Fi 5, which helps devices save battery by scheduling transmission times. Actually, Target Wake Time (TWT) is a feature introduced in WiFi 6, not WiFi 5. TWT allows devices to schedule specific times for data transmission, which helps conserve power and extend battery life by minimizing unnecessary wake-ups.
Statement 2 is correct: The fifth generation of wireless networking technologies, known as Wi-Fi 5 or IEEE 802.11ac, uses the 5GHz band frequency to deliver high throughput in wireless local area networks (LANs).
Statement 3 is correct: Wi-Fi 5 supports wider channels, which can increase the data transfer rate. The maximum theoretical speed for Wi-Fi 5 is 6.9 Gbps, which is significantly faster than the maximum speed of 600 Mbps for Wi-Fi 4. Wi-Fi 6 also provides faster speeds than previous generations of Wi-Fi, both for individual devices and for the network as a whole, especially in environments with several connected devices. Additionally, it includes enhanced security features to ensure secure internet use. And finally, one of the benefits of Wi-Fi 6 is its backward compatibility with Wi-Fi 5 and Wi-Fi 4 devices, meaning that even if you have older devices that don't support Wi-Fi 6, they can still connect to a Wi-Fi 6 network.
