“…In order to capture small scale fading variation due to spatial offsets, the receiver cart is moved within a square of at least 0.5 m × 0.5 m while the MISO channel impulse responses are being captured. The size of this 0.5 m × 0.5 m measurement grid falls within the range of grid sizes reported for capturing small scale fading in a local neighbourhood [28,29]. The measurements captured using this approach are referred to as spatial measurements.…”

This radio channel measurement campaign characterizes the propagation conditions experienced in a dense urban environment over fixed backhaul links between wireless devices that are mounted on utility or traffic light poles. The measurements characterize the 2×1 multiple input single output channel in the 2.45 GHz band for both spatially separated omni antennas and cross polarized directional antennas. Results presented include both small and large scale channel statistics, antenna correlation coefficient values and the off-broadside rejection achieved with the directional antennas.Index Terms-radio propagation, wireless mesh networks, MIMO, Ricean channels, fading, frequency selective fading channels, multipath channels, land mobile radio cellular systems electrical engineering in 2016, both from the

“…They used measurements in rural Virginia to develop a new RMa PL model for 73 GHz that is more accurate than the existing 3GPP RMa models and can be used for frequencies from 0.5 GHz to 100 GHz. Chee et al [14] studied the effects of carrier frequency, antenna height and season on a FWA network deployed in a rural area at 825 MHz and 3535 MHz. They found that the frequency dependence of a wireless channel varies strongly with the environment.…”

Great progress has been made in providing convenient wireless communications with easy connectivity for users everywhere. Many empirical path loss (PL) models have been developed to assess the performance of new radio networks. This paper first studies the state-of-the-art of empirical PL models, along with vegetation effects on radio signal propagation. Next, an accurate empirical PL model is proposed for fixed wireless networks under challenging rural propagation conditions. The proposed model is based on a Canadian dataset from a wireless internet service provider, using the Wireless-To-The-Home technology in the unlicensed 900 MHz, 2.4 and 5.8 GHz ISM bands and in the licensed 3.65 GHz band. The proposed model considers several parameters, such as line-of-sight obstructions, frequency bands and dynamic link distance splitting, in addition to seasonal variations in PL attenuation. It outperforms other models in terms of accuracy when tested on a dataset from a different Canadian region, and it provides excellent and steady accuracy when tested on a largely different open-access dataset for mobile communication technology from seven different regions in England.INDEX TERMS radio signal propagation conditions, propagation empirical models, path loss, seasonal effect.
