Implementing an automatic payment device helps public transport operators like urban buses and citizens by guaranteeing an agile, fast, and safe service since users would only carry an NFC card, replacing cash for fares. Many factors are involved in the proper functioning of an NFC card, such as power autonomy, interference from wireless signals, weather, and manufacturing components. This study is about evaluating the wireless signals that interfere with the operation of the prototype to determine its implementation feasibility. Essential stages are considered to reach this goal, such as recognition of the route of a certain transport unit, design and development of the automatic charging prototype, the website for its administration, and clear interference tests of the main signals such as Wi-Fi, Wimax, LTE, and others. It was determined that within the simultaneous operation between the interferences of different wireless technologies and under the same environment of the smart charging prototype, they work in the 2.4GHz band, producing packet collisions due to the presence of interference, being the Wimax wireless technology the one that mostly interferes in the operation, causing slowness in the transfer speed. The closer the interference is to the prototype, the greater the affectation. It is recommended to make changes to components in the prototype construction accompanied by an optimal power backup and an autonomous device in terms of signal reception that works without depending on a Wi-Fi signal but its module that receives the signal, for example, with the integration of a chip from a telephone company |
