A wireless local area network (WLAN) provides wireless network communication over short distances using radio or infrared signals instead of traditional network cabling.
What Does WLAN Mean?
WLAN means wireless local area network. A WLAN can be built using any of several different wireless network protocols, most commonly Wi-Fi or Bluetooth.
Network security remains an important issue for WLANs. Wireless clients usually have their identity verified (a process called authentication) when joining a wireless LAN. Technologies such as WPA raise the level of security on wireless networks to rival that of traditional wired networks.
WLAN Devices
A WLAN can contain as few as two devices and as many as one hundred or more. However, wireless networks become increasingly difficult to manage as the number of devices increases.
Wireless LANs can contain many types of devices, including:
- Mobile phones
- Laptop and tablet computers
- Internet audio systems
- Gaming consoles
- Other internet-enabled home appliances and devices
