What is Wireless Network Architecture?
Wireless Network Infrastructure Hardware, software and communication technologies that provide connection and communication of other devices without physical network cables. It is the backbone of Wi-Fi network as it provides the necessary communication between laptop, smart phone, tablet computer, Internet of Things devices and the business application system across the building, office, campus, cities and towns.
Wireless network infrastructure fundamentally is based on use of Radio Frequency (RF) signals to transfer data from associated devices to wired network. Wireless network infrastructure generally comes along with internal and external APs, a variety of switch, router, controller, antenna, security system etc. for wireless network.
Core components include:
- Wireless Access Points (APs)
- Wireless Controllers
- Routers and Gateways
- Antennas
- Network Management Software
- Authentication Servers
- Wireless Security Systems

How Wireless Networks Work
Wireless networks enable Internet and data connectivity between various wireless devices by means of radio frequency (RF) signals rather than Ethernet cables. The Wi-Fi enabled device (laptop, Smartphone, etc.) connects to the wireless network and transmits data through the wireless access points (APs).
First device scans for wireless networks and establishes a connection with the wireless access point. Once connected, data is passed wirelessly to the access point which then routes it through switches, routers and internet gateways to its destination and the reply is sent back to the device.
Basic Process
- Wireless Request is sent by the device.
- The Access Point Start up receives.
- AP sends traffic to network switch/router
- Router routing traffic to destination.
- The response is sent back to AP.
