What is WLAN?

WLAN stands for Wireless LAN (wireless local area network) or Wi-Fi . This allows a computer to connect to the Internet wirelessly.

WLAN’s use radio or infrared signals instead of the traditional network cables. A wireless connection to the Internet is a more modern alternative than a wired network that relies on copper and/or fiber optic cables.
WLAN can link computers and different devices and provides a connection through an access point to the wider Internet. A access point is called a hotspot. This gives users the mobility to move around within a local coverage area and still be connected to the system.

A wireless network offers advantages and disadvantages when compared to a cable connection. The main advantage of a wireless network is mobility and the elimination of any cables. There is no limit to number of devices that can be supported. It depends on the bandwidth and physical layout.
A wireless network is not as expensive to install or expand. You can connect anywhere there is a signal. Set up is fast and easy. WiFi can be installed in an area where cables cannot be run, such as a outdoor area or in a historical building.

Disadvantages of wireless include the potential for radio interference due to weather or other wireless devices. Its possible a transmission can be slow, and security is harder to guarantee, so it should always be encripted.

Wireless is rapidly gaining in popularity for both home and business.
Wireless LANs have become popular in the home due to ease of installation and the increasing popularity of laptop computers. Your laptop can tap into the Internet anywhere in your house!

In addition to private use in homes and offices, Many public businesses such as coffee shops and malls have begun to offer wireless access to their customers, sometimes for free. You can now take your laptop down to the local coffee shop, and surf the net while sipping a cup of cappuccino.
