Internet of Things (IoT) Practice Exam

Protocol IEEE 802.11 is primarily associated with which type of network?

1. Personal Area Network (PAN)

2. Wireless Local Area Network (WLAN)

3. Wide Area Network (WAN)

4. Mobile Ad-hoc Network (MANET)

The correct answer is: Wireless Local Area Network (WLAN)

The protocol IEEE 802.11 is primarily associated with Wireless Local Area Networks (WLAN). This standard comprises a set of specifications for implementing wireless communication within a limited range, typically around a few hundred meters. It facilitates the wireless connection of devices such as laptops, smartphones, and printers to a local network, allowing users to access the internet and share files without the constraints of physical cabling. The IEEE 802.11 standard encompasses various features and functionalities, including different frequency bands (like 2.4 GHz and 5 GHz), multiple communication protocols, and security measures such as WPA2 and WPA3 for safeguarding data transmission. This makes it ideal for home networking, office environments, and public spaces where mobility and connectivity are essential. In contrast, Personal Area Networks (PAN) are designed for small personal devices and typically cover very short distances. Wide Area Networks (WAN) encompass larger geographic areas and connect multiple LANs, often requiring different technologies. Mobile Ad-hoc Networks (MANET) involve a decentralized network of mobile devices that spontaneously form a network without centralized management. These do not align with the intended use and capabilities of the IEEE 802.11 protocol, which is specifically tailored for WLAN scenarios.
