ITU‐T's Technical Reports and Specifications 325 One of the main challenges in the build time of a MANET is to equip each device to continuously maintain the information required for routing. Such networks result from the combination in each of the terminals or nodes of the layers identified ICT infrastructure, i.e., the data communication and the detection layers, and they can operate independently or be connected to the Internet. Other infrastructure to be considered is the HAPS (High‐Altitude Platform Station). Its ability to vary the beam communication is highly adaptable in an urban environment, directing more bandwidth to where it is most needed in the daily evolution of zonal needed for data traffic. Although, it's commercial use is now limited and focused on remote areas (such as Alaska), ITU‐R has already defined the total area coverage of a HAPS aircraft in the bands 47/48 GHz and have divided it into three areas: urban, suburban and rural (they are needed to ensure consistent broadband users throughout the visibility zone on the floor of the HAPS). The Urban area coverage extends between 36 and 43 km from a point directly under the platform. Users of these areas can be portable modems. The Suburban Urban Area Coverage is up to 76.5 / 90.5 km, depending on the altitude of operation of the HAPS. Users from suburban area coverage should use high gain directional antennas and transmit power. Besides, there are also business technology initiatives that take advantage of the height, both for energy production and for the establishment of communication nodes (and meteorological studies). One example is the BAT (Bouyant Airborne Turbine) that fails high winds to produce power and to transmit it to land routes subject to the anchors. Clean Energy + Point Communication are a typical combination of infrastructure for future SSC.

However, differences can be drawn from debating what are the key factors that would influence knowledge and innovation45. ____________________ 45 This document focus on the \"hard\" part associated with the influence of business; however there are explanations due to the influence of persons (talented and creative people changing the structural design of cities).
