The Portable Internet
The Portable Internet: Rajesh Jain points to a report from the International Telecommunication Union about the merging of three distinct types of communications technologies to create meshes of coverage over large areas. The WiMAX and IMT-2000 protocols can provide coverage for up to 50 kilometers from a base station; WiFi, 802.11b and others handle intermediate-range connections; and other protocols such as Bluetooth and RFID allow for connections within the personal range. Highly-developed areas already tend to have permanent landlines, increasing in capability as each decade's new technology eclipses the previous decade, but developing countries can skip all that and move to a combination of fixed-connection and wireless mesh, with the side benefit of enabling connectivity models that let you easily move around. But then, the security models start to change too.....
