<P> Sneakernets may also be used in tandem with computer network data transfer to increase data security or overall throughput for big data use cases . Innovation continues in the area to this day, for example AWS has recently announced Snowball, and bulk data processing is also done in a similar fashion by many research institutes and government agencies . </P> <P> Internet access is limited by the relation between pricing and available resources to spend . Regarding the latter, it is estimated that 40% of the world's population has less than US $20 per year available to spend on information and communications technology (ICT). In Mexico, the poorest 30% of the society counts with an estimated US $35 per year (US $3 per month) and in Brazil, the poorest 22% of the population counts with merely US $9 per year to spend on ICT (US $0.75 per month). From Latin America it is known that the borderline between ICT as a necessity good and ICT as a luxury good is roughly around the "magical number" of US $10 per person per month, or US $120 per year . This is the amount of ICT spending people esteem to be a basic necessity . Current Internet access prices exceed the available resources by large in many countries . </P> <P> Dial - up users pay the costs for making local or long distance phone calls, usually pay a monthly subscription fee, and may be subject to additional per minute or traffic based charges, and connect time limits by their ISP . Though less common today than in the past, some dial - up access is offered for "free" in return for watching banner ads as part of the dial - up service . NetZero, BlueLight, Juno, Freenet (NZ), and Free - nets are examples of services providing free access . Some Wireless community networks continue the tradition of providing free Internet access . </P> <P> Fixed broadband Internet access is often sold under an "unlimited" or flat rate pricing model, with price determined by the maximum data rate chosen by the customer, rather than a per minute or traffic based charge . Per minute and traffic based charges and traffic caps are common for mobile broadband Internet access . </P>
