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.

Mobile and wireless technologies provide an ever-increasing number of opportunities for companies to innovate and grow. Wireless telecommunications providers are experiencing dramatic growth in mobile data transmission, driving demand for mobile devices supporting data-intensive consumer-based applications, such as location-based services and 3D gaming. Mobile and wireless technologies can be complex. Their associated infrastructure is crucial to mission-critical applications such as defense, emergency response, and business, including logistics, smart city, networking connectivity, supply, and more.

Mobile network infrastructure is based on a software-defined architecture that allows greater flexibility, increased adaptability to new capabilities, and automation, allowing wireless operators to compete better.

Service-based Architecture

New mobile and wireless systems were designed from the ground up instead of adapting to previous generations. Previous generations were all built on top of the following previous generation. Architecture is a Service-based Architecture with crucial components:

  • Authentication Server.
  • Policy Control.
  • Network Slice Selection.
  • Session Management.
  • User plane.
  • Access and Mobility Management.

Unified Data Management.


Wireless technology uses electromagnetic waves, such as radio waves, to transmit data and information without needing physical connections, such as cables. This technology has become increasingly prevalent in recent years, with a wide range of devices using wireless technology to communicate data and information.

Wireless technology has many advantages over wired technology, such as increased flexibility and mobility and reduced cost and installation time. Wireless technology makes it possible to connect devices over long distances without needing physical connections, which can be expensive and time-consuming to install. In addition, wireless technology allows for creation of networks that can easily be expanded and modified, making it ideal for a wide range of applications.
