3. Getting Started
WIBS are used to provide innovative services for enhancing mobility in a wireless office
environment and covering hot spot or dead spot of traditional public cellular or PCS networks, such
as on campus, on the load, etc. WIBS is connected to the IP network through 10/100base-T
interface and related software stack (H.323, etc.), and can also be used for conventional PCS or
cellular systems. WIBS is a part of an IP-based wireless office system which includes WIBS, WIS,
IP-PBX, IP-Phones, etc.
