These standards, designated by the IEEE (Institute of Electrical and Electronics Engineers), define the specifications for WiFi technology, including its speed, range, and capacity.
As you continue with this tutorial, both beginners and advanced users will appreciate the significance of WiFi in powering wireless networks. We'll continue our learning journey by exploring the different types of wireless networks in the next section.
Welcome to the third installment of our tutorial. In this section, we'll explore the various types of wireless networks: WPAN, WLAN, and WWAN. Understanding these different network types is crucial, whether you're a beginner or advanced learner, as it provides a broader context for how wireless networks function and are applied in various scenarios.
A WPAN is a network that connects devices within a relatively small area, typically within a person's reach. For example, you create a WPAN when you connect your smartphone to your Bluetooth headphones. WPANs are ideal for connecting personal devices that are close together.
Key protocols used in WPANs include:
A WLAN is a network that connects devices within a limited area, such as a home, school, or office. The most common type of WLAN is a WiFi network. WLANs allow multiple devices to connect to the internet through a single connection point, such as a wireless router.
A WWAN covers a large area, typically provided by telecommunication providers. It's used to connect mobile devices to the internet over a large geographical area. The most common example of a WWAN is a cellular network, like 4G or 5G networks.
Understanding these different types of wireless networks is key to grasping the complexity and versatility of wireless technology. As we progress in this tutorial, we'll delve into the crucial topic of wireless network security. This topic is important for all users, beginners and advanced alike, as it's essential to protect your wireless connections from potential threats.
