Abstract

We analyze the impact of a Radio over Fiber technology in a Wireless Sensor Network based on FSK and MSK modulation schemes. Experiments were carried in a WSN testbed at 915 MHz frequency range to verify the impact of RoF used as a backhaul in the sensor coverage. Moreover, it has been investigated the impact of the introduction of multiple cells. In order to avoid radio propagation uncertainties a channel emulation system was applied and the performance parameters measured were Packet Error Rate and Received Signal Strength Indicator. The results demonstrate the viability of the use of RoF as a backhaul for WSN, considering the correct impact in the coverage distance by the use of an appropriate low noise amplifier.
