“…Also, this system contributes to precision agriculture by determining the maximum communication distance between two wireless nodes, to efficiently plan the number of nodes in the WSN and their coverage area in sensor/actuator deployment within an agricultural field. There are other studies on this subject, which also employ wireless sensor networks, and use mobile devices based on Arduino boards and Xbee radio modules [38][39][40]. In our case, for the RSSI measurement of radio waves, we use a board that has an integrated radio module in the 2.4 GHz ISM band [41].…”

Precision agriculture and smart farming are concepts that are acquiring an important boom due to their relationship with the Internet of things (IoT), especially in the search for new mechanisms and procedures that allow for sustainable and efficient agriculture to meet future demand from an increasing population. Both concepts require the deployment of sensor networks that monitor agricultural variables for the integration of spatial and temporal agricultural data. This paper presents a system that has been developed to measure the attenuation of radio waves in the 2.4 GHz free band (ISM- Industrial, Scientific and Medical) when propagating inside a tomato greenhouse based on the received signal strength indicator (RSSI), and a procedure for using the system to measure RSSI at different distances and heights. The system is based on Zolertia Re-Mote nodes with the Contiki operating system and a Raspberry Pi to record the data obtained. The receiver node records the RSSI at different locations in the greenhouse with the transmitter node and at different heights. In addition, a study of the radio wave attenuation was measured in a tomato greenhouse, and we publish the corresponding obtained dataset in order to share with the research community.

“…The total attenuation caused the millimeter wave to have a short propagation distance that is just suitable for short range wireless communications. Line of sight (LOS) transmissions are more likely needed in the millimeter wave to maintain the received signal quality [6]- [9]. Compared to lower frequencies such as microwave spectrums, millimeter wave frequency spectrums * subuhpramono@staff.uns.ac.id provide a high capacity and data transfer rate, but their transmission waves have issues with propagation.…”

Researchers are keen to continue developing and investigating millimeter wave spectrum bands because these bands potentially provide broadband bandwidth for extremely high data transfer rates. This paper presents a comprehensive review of the recent millimeter wave antenna development, especially for 30-40 GHz, 60 GHz, and 140 GHz, with their characteristics, limitations, and challenges. Several previous millimeter wave antennas are introduced, including their broadband bandwidth, gain, feeding technique, substrate, and beamwidth. Based on their measured performances show that the millimeter wave antenna has great potential to support realizing the extremely high transfer data rate in wireless communication systems.
