or business complex or campus. Establish point-to-point link between large skyscrapers or other office buildings or airports. Bring Internet to remote construction sites or research labs. Simplify networking technologies by coalescing around a small number of Internet related widely used technologies, limiting or eliminating legacy technologies such as shortwave radio so these can be dedicated to uses where they actually are needed. Bring Internet to a home if regular cable/DSL cannot be hooked up at the location. Bring Internet to a vacation home or cottage on a remote mountain or on a lake. Bring Internet to a yacht or large seafaring vessel. Share a neighborhood Wi-Fi network. Nonprofit and Government Connect widespread physical guard posts, e.g. for foresters, that guard a physical area, without any new wiring In tourist regions, fill in cell dead zones with Wi-Fi coverage, and ensure connectivity for local tourist trade operators Reduce costs of dedicated network infrastructure and improve security by applying modern encryption and authentication. Military Connect critical opinion leaders, infrastructure such as schools and police stations, in a network local authorities can maintain Build resilient infrastructure with cheaper equipment that an impoverished war-torn region can afford, i.e. using commercial grade, rather than military-class network technology, which may then be left with the developed-world military Reduce costs and simplify/protect supply chains by using cheaper simpler equipment that draws less fuel and battery power; In general these are high priorities for commercial technologies like Wi-Fi especially as they are used in mobile devices. Scientific research A long-range seismic sensor network was used during the Andean Seismic Project in Peru. A multi-hop span with a total length of was crossed with some segments around . The goal was to connect to outlying stations to UCLA in order to receive seismic data in real time. Large-scale deployments The Technology and Infrastructure for Emerging Regions (TIER) project at University of California at Berkeley in collaboration with Intel, uses a modified Wi-Fi setup to create long-distance point-to-point links for several of its projects in the developing world. This technique, dubbed Wi-Fi over Long Distance (WiLD), is used to connect the Aravind Eye Hospital with several outlying clinics in Tamil Nadu state, India. Distances range from five to over fifteen kilometres (3–10 miles) with stations placed in line of sight of each other. These links allow specialists at the hospital to communicate with nurses and patients at the clinics through
