mpact of mobile Internet will range from a low of $3.7 trillion to $10.8 trillion. To get a sense of the impact of Cloud computing, we could peruse the following estimates: In an era ruled by Moore's law, it takes about 18 months to double server performance, but the Cloud now enables rentals to be SO low as to make the cost of owning a server three times that of renting one in the Cloud. 2.7 billion people could be served from the Cloud using 50 million servers. There could be up to $3 trillion of IT spent that could potentially be on the Cloud. By 2025, it is estimated that the potential impact of Cloud computing will range from a low of $1.7 trillion to a high of $6.2 trillion. So, how should all of this be of interest to mobile operators? As a mobile network service provider, you should look to capitalize on the Cloud and solidify your strategy. You must look to enable services through the Cloud and the applications that will enable the end users to take advantage of them. This could also include the ability to enable access to popular Cloud services through your mobile Internet. You could also design plans and services to make it easier for end users to use the Cloud for their data and services. As a business that provides solutions to be deployed, your network roadmaps must reflect services that enable the Cloud as an integral part of the solution. You must brainstorm to understand which parts of the network can enable Cloud interactions directly and which parts could aggregate and interoperate with existing Cloud services. CHAPTER 3 DEPLOYMENT CHALLENGES IN EVOLVING 4G Summary This chapter started by looking at key challenges facing LTE deployment-those associated with the technology itself and also the business challenges that are related to making the investments necessary-and the uncertainty surrounding the market evolution. From there we went through some concepts related to recent evolutions and trends in mobile and Internet usage, in terms of the different types of devices being used to access the In
