Making Telecoms Work modulation schemes that are inherently noise sensitive and perform poorly most of the time resulting in user frustration and packet send retries that absorb network bandwidth and battery and network power. The higher-order modulation schemes require more linear and therefore less power efficient radio-frequency transmitters. The adaptation schemes needed to manage and mitigate these effects in turn introduce variable delay and add to the overall energy budget. At this point you might question why the fixed and mobile telecommunications industry remains SO set on IP network implementation. The idea that LTE networks will be more cost efficient and power efficient than the networks they are replacing is naive. The notion that they can be profitable is not. Telecoms - The Tobacco Industry of the Twentyfirst Century? Telecommunications networks including cellular networks now provide access to instant in- formation on a scale that would have been hard to imagine thirty years ago. Information addictive and develops dependency, two core ingredients of a successful business model. Even better, the capital and energy costs of storing and managing the information in thousands of server farms around the world are paid for by other third parties. For 150 years (from 1850 to the year 2000), the telecommunications industry has made money out of people's desire and need to interrelate to one another - the telegraphy and telephony age. Telegraphy and telephony provided a basis for social and economic progress based on social, economic and business efficiency, profitability with a social purpose and associated emotional value. Information networks extend that model by helping us to interrelate with the physical and intellectual world around us. Earlier chapters discussed the role of the super phone and the interrelationship with the physical world around us. The next ten chapters shift this focus to this interrelationship between information networks and the intellectual world.
