PCPR (Proceedings of the CPRLatam Conference) is published annually by the Latin America Communication Policy Research Network. CPRLatam is organized exclusively for charitable, scientific, education and consulting purposes. The main goal of the organization is to provide training and consulting services for scholars, private sector, and government officers on ICT policy, and to hold an annual conference for the exchange of non-partisan research, education, and information aiming to increase academic, private and government officers and the public awareness regarding ICT policy issues. This volume of the PCPR held in Cancun (Mexico) follows a set of annually international conferences, which took place in Buenos Aires (Argentina), New York (United States), Mexico City (Mexico), Brasilia (Brazil), Lima (Peru), Valparaiso (Chile), Mexico City / Oaxaca (Mexico), and Bogota (Colombia). The 2015 CPRLatam Conference was organized in coordination with the Latin American Telecommunications Congress (CLT2015), and the ITU Regional Fora on Development (RDF 2015) and on Optimization and Efficient Use of Spectrum.
