The Study of Roadsides WiFi Performance and Analysis via Signal Strength Assessment: A Case Study in Bangkok Metropolitan Street
Nilamit Nilas, Pakamas Choosit · 2023
WiFi access points are abundance in the city and metro area. Employing these street WiFi for data and Internet connection have many potentials. However, these WiFi locations and signal qualities are uncategorized and insufficiency information for use. The research conducted in this study involved collecting signal strength data from several access points situated along the roadsides, specifically from Lumphini park to the Rama VII bridge in northern Bangkok. To analyze this data in case study, a Python program was utilized to manipulate and receive signals via the RTL8822ce WiFi module. Upon analyzed, it was discovered that a remarkable signal strength was exhibited by a total of 271 WiFi interfaces. This exceptional signal strength indicates excellent connectivity along 20 km distance of roads, showcasing the robustness of the network infrastructure. For over 90% from the service providers, this included service monitors as well as services for multiple client users. In terms of WiFi interface types, the analysis revealed that the majority of the access points operated on the IEEE-802.11ac standard, accounted for estimated 49.95% from the total case study data. However, the IEEE-802.11ax standard counted for around 28.93% of the WiFi interfaces, while the IEEE- 802.11n standard counted for approximately 20.74%.
