El autor invitado de esta entrega de TELOS ejemplifica bien, en su biografía y en el contenido de su texto, el salto adelante experimentado por buena parte de América Latina en cuanto a la extensión y la apropiación de las Tecnologías de la Información y la Comunicación (TIC). Germán Rey, avezado investigador en cultura y comunicación, es en efecto, director del centro Attico de Bogotá (Universidad Javeriana), un vivero de innovación abierto a todo tipo de creadores; y en su artículo no solo analiza los cambios sorprendentes de equipamiento de la población colombiana en la última década sino, sobre todo, la transformación inducida en las prácticas culturales y comunicativas ...
Get up to speed with the protocols, network architectures and techniques for 5G wireless networks with this comprehensive guide.
Seventeen-year-old Miguel Angel spends every minute after school at the Packing Shed, working out with the Alisal Boxing Club. He dreams of becoming a champion so he can get his mother and five siblings out of their cramped one-bedroom apartment in one of Salinas’ poorest barrios. But suddenly his life gets more complicated.

After the success of The Northern Clemency, shortlisted for the 2008 Man Booker Prize, Philip Hensher brings us another slice of contemporary life, this time the peaceful civility and spiralling paranoia of a small English town.
The 5G Myth explains why the vision of 5G, the next generation in mobile telephony, heralded as a huge advance in global connectivity, is flawed and sets out a better vision for a connected future. It explains why insufficient technological advances and inadequate profitability will be problems in the widespread implementation of 5G. The book advocates a focus on consistent connectivity everywhere rather than fast speeds in city centers. William Webb looks back at the transitions through previous generations of mobile telephony and shows what simple extrapolations of trends would predict for 5G. He discusses whether the increases in speed and capacity promised by 5G are needed; if the required technology is available; whether a sound business case can be made for the deployment; and asks why, given this, the industry appears so supportive of 5G. He then puts forth the argument in favor of consistent connectivity of around 10Mbits/s everywhere as a more compelling vision and shows how it can be delivered via a mix of 4G and Wi-Fi.

THE Encyclical of our Holy Father, Pius XI., on the Institution of the Feast of Christ Our King is a fitting crown to the devotion and the vast spiritual awakening which marked the Holy Year, 1925. In fulfilment of the commission of Our Lord to St. Peter, and aided by the light and grace that are given to every man according to his need, the Vicar of Christ addresses words of timely guidance and help to the Catholic world. We need that guidance today. In their greed for wealth, the senseless hurry of business, and the rush for pleasure men forget, then reject, Divine things. Our superficial education, the shallow science and the sensationalism of the newspapers bewilder men's minds. They can...
