• Abstract:

  This work proposes an

  experimental coverage evaluation of a Wireless

  Sensor Network (WSN) connected with Radioover-Fiber (RoF) network operating as system

  backhaul that can be implemented in WSN

  under the Internet of Things (IoT) context. The

  RoF is assembled in a bus topology and has

  a radio repeater for signal distribution to the

  WSN. Impairments present in RoF systems that

  degrade the RF signal are analyzed. The main

  parameter used to evaluate the WSN coverage

  of this system is distance by Packet Error

  Rate analysis. The results show that the radio

  repeater device brings benefits to signal quality,

  improving the area coverage of a WSN. The bus

  topology used for RoF reduces equipment cost.
