Design of low-cost multimode fiber-fed indoor wireless networks

摘要

A low-cost option for transporting global system for mobile communication, Universal Mobile Telecommunication System and wideband local area network (WLAN) signals using multimode fiber (MMF) with 850-nm vertical-cavity surface-emittingudlasers (VCSELs) is investigated through range predictions from a link budget analysis. These predictions are experimentallyudverified for WLAN signal transmission in an office environment, using a commercial access point and a 300-m (OM1/OM2) MMFudlink with low-cost 850-nm VCSEL transmitters. The analysis indicates that good performance and signal coverage is possibleudwith optimum design of indoor fiber-fed wireless systems, even when using such inexpensive components.
