performance and availability of existing text-based applications, but also enable entirely new ones,

such as traffic signal management, parking enforcement control, automated meter reading,

location-based services, land management, digital tourism and much more.

As a result, local government and public safety employees can make faster, more informed

decisions and are better able to manage their resources. By avoiding the need to transfer data

between department servers and vehicle computers, they can also save considerable time filing

reports and taking care of other administrative tasks.

In one city on the east coast, police officers use the Wi-Fi hotspots downtown and in city parks and

school areas to file paperwork, download license plate alerts, and upload captured license plate

data from their license plate recognition system. They can also view and monitor video images of

all the surveillance cameras placed in strategic city locations on their police laptops. The images

are pulled down from the network at the hotspot location and streamed to the Cisco 3200 Series

Wireless and Mobile Router in the police car. With so many tools at their disposal, law

enforcement can be much more self-reliant, easing the burden on dispatchers and other support

staff.

In another scenario, a police officer using a digital camera and a handheld scanner can capture

suspect mug shots and fingerprints at the point of arrest. The information can then be transmitted

from the officer’s vehicle back to headquarters over a Cisco outdoor wireless network, and then

automatically cross-referenced with regional, state, and federal databases.

Without this technology, a suspect typically would be transported back to headquarters to be

photographed and fingerprinted by police technicians, who would then manually enter the results

into relevant databases.

In addition to saving time and effort, a Cisco wireless LAN enables the officer to conduct a real-

time database query on the suspect, comparing the fingerprints against thousands of others on

file. This not only verifies the suspect’s identity, but could potentially lead to a match with prints

from an unsolved case.

Some of the most exciting applications for high-speed wireless LANs involve the ability to send

and receive live video feeds. These days, most videos are converted on the Internet protocol that

defines how information is passed between systems via the network. It can be used to remotely

monitor public areas and to gain insight into rapidly developing or escalating situations.

The Solution: Next-Generation Wireless Mesh Deployment for a Versatile and

Flexible Outdoor Network

The cornerstone of the Cisco Outdoor Wireless Networking solution is a high-speed wireless

broadband network infrastructure providing wide area hot spots and hot zones coverage.

The next-generation Cisco Aironet

1520 Series wireless broadband platform (Figure 2) is a key

component of the Cisco Unified Wireless Network and Cisco Outdoor Wireless Networking

solution, providing connectivity with other Cisco mesh access points to form an outdoor wireless

mesh network. This versatile platform makes it easy to integrate additional radios in order to meet

network and application requirements. The platform provides flexibility and speedy deployment of

new applications by allowing the wireless infrastructure to extend services to third-party devices

such as video cameras, automated meter readers, and sensors.
