Data collection of the radio wave propagation loss in farm fields is valuable to design a wireless network in a farm. They are used in calculating the link budget to establish a proper and efficient node arrangement. In this study, propagation losses in a 50 × 50 m mulberry field were measured in 920-MHz band with respect to the azimuthal angle of the propagation direction to arrays of bushes. Received...
Collecting data of propagation losses in farm fields is important to design a wireless network in a farm. They are used in calculating the link budget to establish a proper and efficient node arrangement. In this study, propagation losses in a 50 × 50 m mulberry field were measured in 920-MHz and 2.4-GHz bands. Received signal strength indicators (RSSIs) were measured as a function of the distance...
The loss characteristics of radio propagation in 920-MHz band in a farm were investigated. An experiment was carried out in a mulberry field of the area of 50 m × 50 m in order to obtain fundamental data of the path loss in the field. Received Signal Strength Indicator (RSSI) according to the distance between the transmitting antenna (Tx) and the receiving antenna (Rx) was investigated. Tx was placed...
The change of the radio wave propagation loss in 920-MHz band was examined as bushes in a farm grew higher. Received Signal Strength Indicator (RSSI) was measured as a function of the distance between the transmitting antenna (Tx) and the receiving antenna (Rx) in a 50 × 50 m mulberry field. Tx and Rx were placed at a height of 1.5 m. Moreover, the horizontal and vertical polarizations were measured...
