A decade ago, broadband access was mainly offering hundreds of kbit/s, today it provides access within Mbit/s or tens of Mbit/s (i.e. speeds), enabling such things as the provision of high-definition (HD) video as well as ultra-HD videos. For example, almost all transport networks are now fibre based, and the differences shown in Figure 1.2 refer mainly to the last mile. In 2016, LTE networks were offered in at least 165 countries worldwide.
