Mobile broadband closer to contracted speeds

Mobile network users enjoy real speeds closer to those contracted with operators than fixed network users, download or in Upload. The conclusion is contained in an Anacom study that analyzes the quality of broadband Internet access services on the fixed network and, for the first time, also on the mobile network.

According to the study, mobile services offer an average of 89.4 to 100 percent of the speed contracted in the download, data monitored in the Lisbon and Porto areas. At the Upload of files the conclusions point to values ​​between 75.1 to 100 percent of the contracted speed. In the fixed network the real speeds of download are further from the contracted values, varying between 55 and 77 percent.

Best performance

In fixed, Anacom highlights the performance of Cabovisão, which achieves the best results in all tests performed, with 70 percent of the measurements taken producing results above 75 percent of the contracted speed. The worst results go to Sapo, which managed only 10% of the measures to stay above 75% of the contracted speed.

In mobile, TMN and Vodafone are positively highlighted. The first achieves 100 percent download results in both cities and the second achieves the same value in tests for uploading files via FTP.

The values ​​found in this analysis reflect the Relative Speed ​​Index (IVR = average measured speed / maximum contracted speed16 x 100) applied in the analysis for national accesses, as explained by the regulator, in order to normalize the data and facilitate its comparison, given the dispersion of offers in the market.

Download web pages

The difference between technologies is reduced in the access to international servers, both in terms of downloading files and in terms of average time for download of Internet pages by the various services, although here the fixed access technologies register, in general terms, relatively better results than the mobile access services. In national accesses and to the United Kingdom, the download the number of web pages on fixed network services is up to half that registered on the mobile network.

Network latency

Another aspect analyzed in the Anacom study is network latency. That is, the time it takes to transfer an IP packet from source to destination. This is an especially relevant factor in the performance of interactive applications such as VoIP, or in games online. Also in this area, the best results go to the fixed network. Latency on the mobile network is higher for all destinations at around double the values ​​recorded on fixed network services.

The values ​​determined by the regulator show, however, that, even in the worst cases, there are conditions for the support of VoIP services by mobile network services, the same does not happen with games online multi-player, more sensitive to these parameters.

The study presented today was carried out by Anacom in partnership with QMETRICS and in collaboration with FCCN – Foundation for National Scientific Computing. It took place between November 5 and December 21 of the past, in the case of furniture and between October 30 and February 8 of this year, in the case of fixed.
