QoS for Mobile Ultra-Broadband The mobile and wireless network evolution has sped up over the past several decades, since the appearance of digital mobile systems in the 1990s. However, if one wants to see the complete mobile and wireless evolution with the main events in its history, then the timeline will be the following: Invention of electro-magnetic theory in 1861 by J.M.C. Maxwell, who established the theoretical basis for further development of wireless communications. Start of the era of wireless communicatio
