Development of fixed broadband Internet access in Ukraine

Abstract

Nowadays, the level of accessibility to Internet resources and information services to the population is considered the most essential characteristic of the state’s economic development. The United Nations (UN) includes citizens’ right to access the Internet in the list of basic human rights. In order to ensure the provision of broadband access to every citizen throughout the country, the state faces the task of creating the appropriate telecommunications infrastructure. The article considers the task of developing (modernizing) the subscriber segment (level) of the fixed broadband access network (FBA) to the Internet based on the G.fast telecommunications technology according to the ITU-T Recommendation G.9700. The technical characteristics of access network options using multi-pair metal cables of the type TPP-10x2x0.4 and «twisted pair» Cat.5e 10x2x0.5 are being studied. Obtained comparative characteristics of the access speed depending on the frequency and transient characteristics of the cables, power of additive, and transient interference. A significant result is a study of the effectiveness of the implementation of technology for compensation of transient interference between «Vectoring» systems in G.fast transmission systems according to the ITU-T Recommendation G.993. Studies prove that using a cable of the type «Twisted pair» UTP Cat.5e 10x2x0.5 ensures a higher speed of operation than using a cable of the type TPP-10x2x0.4. Without the use of the Vectoring «Twisted pair» UTP Cat.5e 10x2x0.5 transient interference compensation system, it provides 400-500 Mbps FBA speed with a cable length of up to 250 m, which is higher than the TPP cable. The obtained results make it possible to develop economically attractive strategies for the development of FBA networks, taking into account the existing features of the networks. Modernization of the network using G.fast technology can significantly improve access to high-speed Internet for millions of Ukrainian citizens, contributing to the country’s digital transformation and increasing its competitiveness in the global market.
