#### 4.2.1 Geolocation Services Result and Analysis  
This section summarizes the location estimate results and our analysis for each geolocation technique: the W3C Geolocation API, the IP geolocation, and the wi-fi positioning systems. The comparative analysis of location services contains the results of evaluating two parameters. These are as follows:  
* The first parameter is the precision of each service. In our study, the precision attribute refers to the level of accuracy of the latitude and longitude coordinates estimated by the service. It is specified in meters and must be a non-negative real number;
* The second parameter is accuracy, defined as the difference between measured coordinates (longitude and latitude) and the device's actual position during the measurement. This difference in meters was calculated using Python scripts, and it was validated using the distance calculator tool [34]. W3C Geolocation API  
The comparison analysis of the W3C geolocation method was performed on the four devices identified earlier, with different browsers and using two access networks. The results are summarized in Figure 5.  
From the measurements of the W3C geolocation method, when using the Windows device, the following results were obtained, as shown in Tables 3 and 4: We noticed a \begin{table}

Table 2: The characteristics of the devices and web applications. Figure 5: Comparison analysis of the W3C geolocation API method. (**a**) Comparison of W3C Geolocation API accuracy by wireless network (STC_4G); (**b**) Comparison of W3C Geolocation API accuracy by wireless network (DSL). Comparing Google Chrome, Firefox, Microsoft Edge, and Safari, we found that Google Chrome, with an average accuracy of 7.7 m, had greater accuracy than Firefox, and Firefox had better accuracy than Safari. The Firefox browser has an average accuracy of 23.9 m, and Safari has an average accuracy of 25.95 m. Microsoft Edge had the worst performance compared to the other browsers, with an average accuracy of 43.85 m.  
Using the iPhone, the measurements of the W3C geolocation method obtained the following results (summarized in Tables 7 and 8): iPhone browsers have the most accurate location results with an average accuracy of fewer than 20 m, and the Firefox browser had the most accurate location results with an average accuracy of 12.15 m. The Microsoft Edge browser obtained a result close to the value of the Firefox browser with an average accuracy of 13.9 m. The Safari browser also had reasonably good results, locating the device with an average accuracy of 17.95 m. Google's Chrome also got a very good value, close to the accuracy of the Safari browser, with an average accuracy of 18.6 m.
