Study on the quality of the broadband Internet access service
Title: Study on the quality of the broadband Internet access service
Summary:
This report presents the results of the study, conducted for the fourth consecutive year, into the quality, from a user perspective, of the broadband Internet access services in Portugal. The corresponding fieldwork was conducted between 27 November 2009 and 7 February 2010 for mobile accesses, and between 5 December 2009 and 17 March 2010 for fixed accesses. The study was prepared and developed by ANACOM in partnership with QMETRICS and ERICSSON PORTUGAL, with support given by FCCN - Fundação para a Computação Científica Nacional (Foundation for National Scientific Computing).
Among the study’s main conclusions, note is made of the file download speeds using fixed accesses, with average speeds exceeding those of mobile accesses, and upload speeds using mobile technology, which in the most part, exceeded those of fixed technology. Likewise, download speeds were also tested for the transfer of files over a P2P application with fixed access. The performance was found to be considerably inferior to that found with FTP transfer. In terms of perceived quality of Web Browsing, it was found that fixed access provides average download times that are lower than those available using mobile technologies.
The main differentiating factor between fixed and mobile technologies, in terms of results, is manifested above all in network latency (delay in IP packet transmission), which has a very significant effect on interactive applications such as VoIP and online gaming. For this parameter, mobile broadband is reported as having higher latency for all destinations. Even so, the values reported in the worst case do not impede the use of VoIP applications.
The methodology used in this study can also be consulted in the report.

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.
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.
User: Any person or party who uses or requests determined services.
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.
