2.2 Benefits of a Wireless LAN
Wireless Local Area Network (WLAN) systems offer a number of advantages over traditional
wired systems. WLANs are flexible, easy to set up and manage. They are also more economical
than wired LAN systems.

Doctors and nurses can access a complete patient’s profile on a handheld or notebook
computer upon entering a patient’s room.
It allows flexible workgroups a lower total cost of ownership for networks that are
frequently reconfigured.

2.3 Notes on Wireless LAN Setup
When setting up a wireless LAN, be sure to note the following points:
Optimize the performance of the WLAN by ensuring that the distance between access points is
not too far. In most buildings, most WLAN adapters operate within a range of 100 ~ 300 feet,
depending on the thickness and structure of the walls.
Radio waves can pass through walls and glass but not metal. If there is interference in
transmitting through a wall, it may be that the wall has reinforcing metal in its structure. Install
another access point to circumvent this problem.
