Analysis Of Outdoor Location Determination Using Three Access Point 802.11
Introduction to Wireless Fidelity (WI-FI) Technology
Wireless Fidelity (WI-FI) technology has experienced rapid development in recent years, especially with the presence of IEEE 802.11 standards. This technology allows data to be transmitted in a local computer network without requiring cables, using radio waves. One of the important applications of this technology is for the purpose of determining positions, which can be done through access points, base stations, and satellite-based global positioning system (GPS) applications. In this paper, we will discuss the accuracy analysis of location determination using three access points in two fields, namely close range (dean field) and long distance (far Medan).
Background of Location Determination Using Access Points
Location determination using access points is a technique that uses radio waves to determine the position of a device. This technique is widely used in various applications, including navigation systems, tracking systems, and location-based services. The accuracy of location determination using access points depends on several factors, including the number of access points, the distance between access points, and the type of environment in which the device is located.
Methodology of the Study
This thesis examines the level of accuracy in predicting positions using different distance methods for two research fields. The near terrain uses a grid of 4 m x 4 m with a distance between 1 M point, while the terrain far uses a larger grid, which is 30 m x 30 m with the distance between the point of 5 m. The experiment was carried out many times to get reliable data.
Results of the Study
The results showed that the accuracy of position predictions in the near terrain was in an unsatisfactory category, with detection deviation reaching 63%. This shows that there is a significant inaccuracy in determining the position with this method in a denser area. Conversely, for distant terrain, the average detection deviation is better, which is 36%. This indicates that the wider the area of ​​the area, the better the accuracy of positioning that can be achieved.
Factors Affecting Accuracy in Location Determination
Decreased accuracy in close terrain can be caused by several factors, such as radio wave interference from other devices, wave reflections, and physical disorders that are around the area. In far terrain, the factors that cause interference can be minimized, so that the results obtained are more accurate. However, lower results in the near field also show the potential to develop better methods, for example using a more sophisticated signal processing algorithm or the addition of more access points to increase accuracy.
Implications of the Study
In a broader context, this study provides important insights for application developers who require a reliable location determination system, especially in a dense environment. By understanding the limits of the existing method, developers can find alternative solutions to increase position accuracy, such as a combination of Wi-Fi and GPS technology to get better results in various conditions.
Future Directions
With information obtained from this study, we can better understand the challenges that exist in determining positions using wireless technology. In the future, integration between various technologies can be the key to creating a more effective and accurate location determination system. Hopefully this analysis can provide new ideas and insights for anyone involved in the development of communication and information technology.
Conclusion
In conclusion, this study has shown that the accuracy of location determination using three access points is affected by the distance between access points and the type of environment in which the device is located. The results of this study can be used to improve the accuracy of location determination in various applications, including navigation systems, tracking systems, and location-based services. By understanding the challenges that exist in determining positions using wireless technology, we can develop more effective and accurate location determination systems in the future.
