Percentage of nominal internet speed, on average, of 39.26% in the downflow and 62.60% in the upflow is shown by the data of the EETT (National Telecommunications and Post Commission) Annual Internet Report 2016-2017 to the European Commission and European Electronic Communications Regulatory Authority (BEREC) to implement Regulation (EU) 2015/2120 on access to the open web.

As the Commission points out, the very low rate of nominal speed achieved in fixed networks creates a picture of inconsistency between the advertised and the actual speed.

It is attributed to both the xDSL (ADSL, VDSL) technology in which there are significant losses with the user’s distance from the City Center or other concentration point, but also to the fact that current nominal speeds correspond to maximum theoretical speeds at the data connection level and do not take into account factors such as line length and network congestion.

Management practices

In addition, according to the EETT Open Internet Report 2016-2017, the vast majority of traffic management practices concern traffic priority with stricter quality requirements, such as voice or video traffic, or security barriers, or barriers imposed by subscribers themselves (eg parental control services).

Certain cases of deliberate degradation of selected applications require further investigation, as -according to the regulation- there must be equal treatment of traffic, and any differentiation must be based on objective requirements of the different types of traffic.

Moreover, both from the answers to the EETT questionnaire and from the examination of the terms of provision / use of the services, there is a significant deficit in informing the end users about the traffic management practices that are being implemented. There are only general references to the applicability of traffic management techniques, without mentioning the techniques applied and without explaining the impact on the quality of Internet access services.

The vast majority of complaints registered by EETT in the first year of application of the Regulation relate to the general quality of service received by subscribers and a relatively small number related to contract terms and the quality of specific applications and services.

Generally, however, the number of complaints is relatively low, which is also attributable to the low awareness of the subscribers for the regulation, as well as to the rights deriving from it.

National regulation

Priority for EETT is to draft, within 2017, a national regulation on the open internet, which will specify the provisions of Regulation (EU) 2015/2120 and the BEREC guidelines.

Among other things, the national regulation will address the issues raised in the conclusions of this report, such as the fullest awareness of subscribers, the speed characteristics and the possible estimation methodologies to be close to the realistic expected speeds received by the subscribers, and the exact context in which subscribers will be able to claim damages or remedies.

With regard to data quality indicators for mobile communications networks, EETT will put in place in 2017 a pilot mobile hybrid network measurement system that will be able to measure in different locations and for various mobility scenarios.
