Evaluation study of the quality of service of broadband Internet access
Title: Evaluation study of the quality of service of broadband Internet access
Summary:
This report presents the results of the study, carried out for the third consecutive year, evaluating the quality of broadband Internet access services in Portugal, from the perspective of the user, between 5 November and 21 December 2008, for mobile access, and between 30 October 2008 and 8 February 2009 for fixed access. The study was prepared and conducted by ANACOM in partnership with QMETRICS and with the collaboration of FCCN - Fundação para a Computação Científica Nacional (Foundation for National Scientific Computing).
Among the main conclusions of the study, it is noted that the trends in download speeds achieved for international servers, for both types of access (fixed and mobile), are converging. With regard to upload speeds it is seen that the speeds of mobile technology are higher than those provided by fixed technology. It was also found that, in general, with fixed access, the average time taken to download pages was less than with mobile technology, although, for both types of access, the figures are well within the comfort threshold, providing a decent web browsing experience. The main differentiating factor between the fixed and mobile technologies in terms of results, is network latency (delay in transmission of IP packets), which has a significant impact on interactive applications such as VoIP and online gaming.

Broadband: Used to describe services or connections which allow the high speed movement of considerable quantities of information, with upstream speeds in excess of 128 kbps.
Download: To receive data, such as a file with an image or programme, on one computer from another computer, generally a server. It usually refers to the process of receiving information taken from Internet sites onto the computer. The opposite is upload.
Internet: Set of interconnected computer networks in TCP/IP extending around the world, which connects users to companies, pubic administration institutions, universities and other individuals, where servers of information and services (www, email, etc.) are available. It can be accessed with a computer and a modem, through a service provider.
IP - Internet Protocol: Switching protocol of data packets to route and send information over the Internet.
QoS - Quality of Service: Term used for a set of parameters which characterise the performance of a circuit, a network or a service.
Upload: To send data (for example a text file or a programme) from one computer to another computer, generally from the customer's computer to the server. The opposite of download.
VoIP - Voice over Internet Protocol: Voice over Internet Protocol - Consists of converting analogue voice packages into digital packages and making them travel on the Internet.
