“Network Social Benchmark” is an utility application that provides voting (+1 or -1) and speed testing functions on your iPhone. Your votes and results of speed test with GPS-based location can be shared over the Internet. A quality of experience map is created from your votes and results of speed test. You can get and check the quality of experience map on your iPhone. Note that this application will send your location and carrier information (e.g., carrier name) to our server when you vote and post results.
