Study of Radio Link Losses in Different Mediums and Receiving Stations

Abstract

Radio link is a wireless telecommunications networking system well-known for its fast connection speed and low cost. This paper contains estimated information about the different reasons behind radio link path loss and how radio link path loss influences the entire communications systems, and the best approach to tackle those issues. Radio link path loss happens when the signal propagates from the transmitter to the receiver and when different objects show up in its way. Radio path attenuation is measured in wireless devices to determine signal quality in output power, latency, signal coverage, strengths, throughput, upload, download speed, etc. In this paper, radio link transmission data of three different receiving stations of Bangladesh have been discussed. As expected, the output power and wireless signal propagation speed decrease with the increase of distance between the transmission and receiving sites. Additional dish reflectors can be utilized in the receiving end to increase the efficiency of the long-distance system. Next, we used Ubiquiti Power Beam M5 400 Wireless 150Mbps, a small radio link device, to measure and analyze the signal attenuation at different surrounding mediums, e.g., concrete, glass, wood, trees. Results show that, the radio link path loss is maximum at concrete mediums and insignificant at glass and woods. This analysis will help to design a better radio transmission system with less distortion and high efficacy.
