WLAN in Everyday Life and Business – Modern Wireless Networks, Devices and Leading Manufacturers

Wireless networking has become an essential part of modern homes and businesses. Whether in private households, home offices, hotels, retail stores or large companies – WLAN connects computers, smartphones, tablets, surveillance cameras, smart-home systems and IoT devices reliably and efficiently.

Today, WLAN is far more than simply “wireless internet.” Modern wireless solutions provide high speeds, intelligent management, advanced security features, seamless roaming and cloud-based administration. At the same time, manufacturers differ significantly in terms of functionality, scalability, performance and target audience.

In this article, we explain the basics of WLAN technology, modern wireless standards and introduce leading manufacturers such as Reyee by Ruijie Networks, Ubiquiti, TP-Link, MikroTik, ASUS, NETGEAR, Cisco, Aruba Networks (HPE Aruba Networking) and Linksys.

What Is WLAN?

WLAN stands for “Wireless Local Area Network” and describes a wireless network that allows devices to communicate with each other and access the internet without physical cables. Communication is based on IEEE 802.11 wireless standards.

Main advantages of WLAN:

No network cables required
Flexible internet access throughout the building
Easy connection of multiple devices
Ideal for smartphones, laptops and smart-home systems
Expandable with access points and mesh systems

Today, wireless networks are standard in nearly every modern environment.
