Wireless Network

Why use Wireless Network? Difficult-to-wire environment Extend wired LANs Frequently-changing environments LAN access for mobile computer users High speed leased line replacement Convenience

Wireless LAN Technology Infrared Technology – Disadvantages: very short distance, low speed, cannot penetrate objects Narrowband Technology One specific radio frequency, obtain FCC licenses Spread Spectrum Technology Wideband radio frequency technique Frequency Hopping, Direct Sequence Use unlicensed ISM band (2.4GHz GHz)

Wireless LAN in MPI Usage: Projects Presentation Conferences & Seminars Exhibitions User Training & Workshop Course Teaching & Learning Cyber Campus ãencourage student & staff to bring their notebooks to access campus network & Internet anytime anywhere

Phase I (Ready in this Summer) ãArea Covers: – Big Auditorium – Small Auditorium – Exhibition Area & Canteen – Library – Training Room of Computer Center Phase II – Covers all classroom and gymnasium Wireless LAN in MPI
