Mobile service coverage compliance
The audit consisted of a drive test throughout pre-defined path to measure the outdoor coverage of the population in the Kingdom via an accessibility test.

Year on year data allows for performance comparison

Mobile Broadband service performance
Performance is tested for HTTP and FTP also this is usually transparent to the end user
![Page 28: 2014](https://reader036.fdocuments.net/reader036/viewer/2022070421/56816368550346895dd440d2/html5/thumbnails/28.jpg)
Mobile Broadband service performance
Test environment choice can lead to very different results
Dongle test performed to:Server in Bahrain BlueServer in India Red
No congestion on links or Mobile network
Default dongle TCP window size used impacting performance due to increased latency to reach server in India i.e. link idle while waiting acknowledgment packet.Performance improved by increase of the TCP window size.
