RoF ARCHITECTURE IN THE MILLIMETER WAVEBAND FOR WIRELESS SENSOR NETWORKS
The Internet of Things (IoT) finds its technological development in the rapid development of computer processes and makes it possible to integrate the physical world into the possible world. By virtually connecting identifiable physical objects to the Internet, the IoT represents a good perspective for application in intelligent transport systems, in ubiquitous home networks, in telemedicine systems, etc. In this article, we propose a radio over fiber (RoF) architecture for wireless sensor networks using bi-directional 60GHz millimeter wave wireless access technologies. This architecture finds its justification in systems which require a very high bit rate, such as high definition video signals, detection, processing, transmission and actuation functions. The performance of the system studied has been evaluated in relation to the bit error rate (BER) for various modulation formats (BPSK, QPSK and 16QAM) as a function of radio distance. Our study reveals that the proposed architecture can be matched in the range of applications for wireless communications in association with the unlicensed 60GHz band. It has the advantage of better capacity, an area of wider coverage and lower investment cost.
