Lebanon mayor Ken Toombs says that the citywide Wi-Fi service has been very well received:
restaurants in town report that visitors are quite impressed with the free, easy-to-use Internet
access, and residents who would otherwise not be able to afford the access fees are very
appreciative of the 10 free hours per month of network access.
Meanwhile, Oliver is busy implementing new
bandwidth-intensive productivity applications for city
workers. “Our goal with the citywide Wi-Fi network is
to extend automated processes to all employees,
whether they work behind a desk, in a patrol car, or
on a maintenance crew,” he says.
Soon public safety officers and public works employees will be able to submit reports, respond to
and generate service orders, and access e mail from terminals in their cars, using the same
applications they work with at the office, freeing them to spend more time in the field. Oliver says
that his police chief expects the online reporting and database applications will help him regain at
least an hour of field time per patrol officer per shift.
Immediate wireless access to city, state, and federal databases will deliver everything from police
photographs to warrants, crime bulletins, and building floor plans to crime scene command and
emergency response crews. Remote, pole-mounted digital surveillance cameras will stream real-
time video from higher-crime areas, providing a cost-effective and visible crime deterrent.
Public works engineers and road crews will have real-time access to the department’s
geographical information system, a database of digital maps illustrating water lines, roads, and
other spatial features that can be updated in the field.
Building officials who spend hours performing inspections will have real-time access to the town’s
electronic permit management system to access and update permits and other records, enhancing
efficiency and providing better service to residents and businesses.
And those are just the short-term plans. As Oliver says, “It is hard to predict how the system will
affect our operations. The enhancements are far-reaching and continually evolving.”
Technical Implementation
The City of Lebanon’s Cisco outdoor wireless mesh network will eventually cover ten square miles.
Cisco Aironet 1510 lightweight outdoor mesh access points scattered over the geographic area
communicate continuously with one another, transmitting data back to a central LAN controller
(hub) then to a wired Internet connection. The 802.11 dual band (2.4 GHz and 5 GHz) Cisco
Aironet 1510 access points can be installed anywhere power is available, without the need for a
network connection.
The overlapping mesh network infrastructure is self-healing. If one or more access point nodes
stop working, neighboring access points will detect the lapse and pick up the transmission
workload with no disruption.
Mesh wireless networks can cover greater distances than bridged wireless networks because the
meshed nodes act as repeaters, passing radio signals along until the wired Internet connection is
found. Expanding the network just requires more access points; no new bridges or hubs are
needed.
