Wireless Network Protocols

Wireless networking protocols, such as Wi-Fi and WLAN (Wireless Local Area Network), allow devices to communicate and access the internet without needing physical cables. Wi-Fi is a widely used wireless networking standard that operates in the 2.4 GHz and 5 GHz frequency bands, while WLAN is a general term used to describe any wireless local area network. Wi-Fi and WLAN use the Internet Protocol (IP) to route data and establish connections between devices.

When a device wants to connect to a wireless network, it uses a wireless networking protocol to broadcast a connection request. The network access point is a device that connects the network to the internet, receives the request, and establishes a connection with the device using IP and other protocols. Once the connection is established, the device can communicate with other devices on the network and access the internet.

Both wired and wireless devices can use IP and TCP/IP to communicate with each other and access the internet. However, the specific protocols and technologies used to transmit the data may differ depending on whether the devices are wired or wireless.

Both wired and wireless protocols can coexist and interact within the same network, allowing devices to connect seamlessly and communicate regardless of the connection type.
