Editing Multicast (section)

=== Types of Wireless Communication ===
'''Unicast''': In a unicast wireless communication, data is transmitted from a single source to a single, specific receiver. This is typical in point-to-point communication, where a device sends data directly to another device. Examples include internet browsing or file downloads.

'''Multicast''': In multicast communication, data is sent from one source to multiple specific receivers, often to a defined group within a network. This is efficient in scenarios like live streaming, where the data is only sent once but received by multiple devices interested in the same content.

'''Broadcast''': Broadcast communication involves sending data from one source to all devices within the network's range. In this case, every device receives the same data, regardless of whether it is requested. Examples of broadcast communication include certain emergency alerts and some radio communications.

'''Security Considerations''': Wireless networks are more vulnerable to security threats compared to wired networks, primarily because their signals can be intercepted more easily. Common security measures include encryption protocols such as WPA3 for Wi-Fi networks, firewalls, and the use of Virtual Private Networks (VPNs) to safeguard communication.

'''Advantages and Challenges''': Wireless networks offer flexibility and mobility, allowing users to connect devices without being tethered to a physical connection. However, they can be affected by interference from physical obstacles, environmental factors, or even other wireless devices, leading to slower speeds or connection issues.<ref>{{Cite book |last=Stallings |first=William |title=Wireless Communications & Networks |publisher=[[Pearson PLC|Pearson]] |year=2009 |isbn=9788131720936 |edition=2nd}}{{pn|date=September 2024}}</ref>
