However,
it is in rapid response to restoring services in urban environments following a disaster
event that optical wireless can be an extremely invaluable technology.
254 Chapter 9
Following a major event such as earthquake or hurricane, network services in an
urban area may be disrupted due to damage to infrastructure. Repairing the damaged
infrastructure and restoring the service may take days if not weeks. However, services
may be restored in a matter of hours by deploying optical wireless mesh networks. This
may be achieved by creating backhaul from a remote location to a building in the area
where the service has been disrupted and then distributing the service throughout the
area by means of optical wireless mesh.
Internet Services in Urban MDU Environment For an urban multi-dwelling unit (MDU)
environment, where only a small number of buildings, if any, are lit by fiber-optic cable,
optical mesh can be deployed to provide ultra-broadband Internet services to their
tenants. Although Ethernet services may not be needed by the end customers, Carrier
Ethernet services provided by a network can only facilitate the delivery of advanced
network services such as VoIP and IPTV.
