read online books The 5G Myth: When vision decoupled from realityAuthor William Webb – Avengersinfinitywarfullmovie.de

A newrevised version of the ground breakingbook, updated with recent developments G the next generation in mobile telephony is heralded as a huge advance in global connectivity But the vision is flawed It is flawed because users will not value the higher data rates that are promised and will not need the higher capacity forecast It is flawed because technological advances are insufficient to realise the vision and because mobile operators are insufficiently profitable to afford it There is an alternative vision where industry focuses on consistent connectivity everywhere rather than ridiculously fast speeds in city centres This short and easily digested book book explains why the vision of G is flawed and sets out a better vision for a connected future Chapterexamines the lessons of history, looking back at the transitions through previous generations and showing what simple extrapolations of trends would predict for G It shows that if previous trends were followed, G would become widely deployed inand deliver realistic end user data rates of Mbits s and an increase in capacity of around x compared to current networks Chapterexamines whether such increases in speed and capacity are needed It shows that users do not value speeds above those already widely available on G It demonstrates that while data requirements are currently growing rapidly, the rate of growth is slowing and if extrapolated will result in a plateau in data rate requirements around , with little growth in the G era Hence, it concludes that the advances in speed and capacity that G might bring are not needed Chapterconsiders whether the technology is available to provide such gains It shows that further capacity improvements are very difficult and likely to be expensive to realise, raising the cost of provision for MNOs It also suggests that some changes to the core network may have unexpected side effects of enabling different industry structures, splitting the functions provided by MNOs today across multiple players Chapterconsiders industry economics and shows that MNOs are in a position of declining revenues relative to GDP, and poor profitability Few expect this to change with G with the result that investment is highly unattractive Chapterasks why, if the position is so bleak, that the industry collectively appears so supportive of G It shows that it is not in the interest of any of the key players to cast doubt on a bullish G vision and that for some the emergence of G is essential to their very survival Chapterexamines the visions set out for G indetail It shows that they are often over stated The collective vision of the MNOs, as set out by the NGMN group is examined in detail and each service is shown to be either deliverable via existing wireless solutions such as G, or economically unviable The chapter shows that few know what G actually is Chapterasks what might transpire in place of the current G vision It suggests that consistent connectivity of around Mbits s everywhere is acompelling vision and shows how it can be delivered via a mix of G and Wi Fi It also lays out a possible path for its introduction showing how this could result in seismic changes to the structure of the industry Chapterlooksbroadly at the communications world, considering the impact of regulations, spectrum and broadband access to the home It shows that regulation is set to maintain the status quo which early chapters have shown to be unsustainable and predicts this will cause further problems for any G vision Chaptersummarises the findings of the book, sets out why the current G vision is a myth, and discusses what islikely to transpire
