RESUMO

This work presents an experimental investigation on the implementation of wireless sensor networks (IEEE 802.15.4) over fiber optics. Such investigation was performed with the utilization of IEEE 802.15.4 transceivers, an optical fiber infrastructure inside a field-trial network, called KyaTera Network, and directly modulated lasers and photodiodes designed for usual lab applications. The analysis comprised optical and electrical signal-to-noise ratio meausermentes and packet error rate evaluation under different conditions of transmission (e.g., payload length and time between consecutive frames). Results indicate that the RF signals of the sensor network may be properly propagated through unamplified optical links of up to 100 km or for longer distances with the use of optical amplifiers.
