1. AP Overview
1.1.1 Overview of Wireless LAN(WLAN)
Wireless LAN(WLAN) refers to a LAN that uses high frequency radiowave instead of
cables for inter-node communication. WLAN operation is defined in IEEE 802.1b. WLAN
transmits high-speed data up to 11 Mbps. WLAN can keep high speed in rural
environment (country area) as well as in buildings and campuses, and supports data
communication with high reliability. In addition, it is easy and fast install it. It is possible to
install WLAN even in places where it is impossible to install wired LANs, and also possible
to install it temperately. Currently connected to ADSL network used for companies or
houses, it aims to provide the wireless LAN service through Access Point
(Integrated Access Point: hereinafter referred to as “The integrated AP”) which
combines ADSL with wireless LAN. The integrated AP, composed of ADSL Access
device and 11M Wireless Access Point, is designed to provide the wireless LAN
service over the high-speed Internet served via ADSL line.
The integrated AP, equipped with 10/T base wired port as 1 port, is designed to
configure 10/T base wired LAN without the help of other equipments. In medical
and education fields, WLAN has shown a rapid growth.
