communications line and resources. When you set up a network,

internet connection. You can set up a LAN using wired
technologies (such as Ethernet) or wireless technologies (such as
Wi-Fi or Bluetooth).
Wireless networks
A wireless LAN or WLAN is a wireless local area network, which
may link two or more computers without using wires. Setting up a
wireless network is easy and allows you to share files, peripheral
devices and an internet connection.

Mobility
Wireless LAN systems allow you and other users of your home
network to share access to files and devices connected to the

Also you can share an internet connection with other computers
in your home.
Installation speed and simplicity
Installing a wireless LAN system can be fast and easy and
eliminates the need to pull cables through walls and ceilings.
Note

any additional charges will be incurred, especially roaming charges.
