High-Speed Wireless WAN

Increasingly, county governments need systems that allow all branches of public service – from courthouses and police stations to public schools and emergency services – to share information quickly and efficiently. This is particularly important for rural counties, which have historically been extremely decentralized. With the help of Cambium Networks' wireless solutions, Orange County, Virginia is on its way to providing services to all its businesses and residents.

Orange County
Located 55 miles southwest of Washington, D.C. and 72 miles northwest of Richmond, Virginia, historical Orange County is a rural community with rolling landscapes and spectacular views of the Blue Ridge Mountains. Founded in 1734, the County’s diversified economy and location make it ideal for business and industry, and its nearly 354 square miles are home to more than 32,000 residents.

Advanced Network Systems
Advanced Network Systems, Inc., headquartered in Charlottesville, Virginia, was selected to provide design and implementation services for the county-wide project. The Company specializes in advanced wireless WAN communication technologies and was responsible for furnishing all systems consulting, engineering, procurement, deployment, systems support and maintenance services.

Situation and Challenge
Faced with performance limitations and infrastructure inefficiencies, multiple Orange County government agencies collaborated to create a high-speed wireless network that would provide a county-wide Local Area Network (LAN), a Wide Area Network (WAN) for each designated government entity and public school, a Metropolitan Area Network (MAN) for inter-governmental connectivity, and a shared infrastructure for Internet access.

Upon review, Orange County found that the wire-line solutions it used in the past were cost prohibitive and that certain locations were too distant to establish connectivity. In addition to spanning a large geographical area that contains many obstructions, Orange County faced a number of technological and logistical challenges associated with their existing network. These included limited intra- and inter-governmental connectivity, an inability to share resources and offer consolidated access to high-speed Internet services, inadequate broadband capacity for new applications, and disparate data and voice systems. The County also required reliable support for a wide range of bandwidth-intensive applications, such as voice-over-Internet Protocol (VoIP), geographic information systems (GIS), video conferencing, video surveillance and distance learning.

Technical Requirements

  • Support for a wide range of applications, including real-time streaming video and IP telephony
  • Ability to operate emergency services from alternative sites
  • High data rates of at least 10 Mbps
  • Ease of management and maintenance
  • Ability to use existing tower structures within the County
  • Stability in obstructed paths and high-interference environments
  • High security to protect sensitive government information over a broadband network
  • Design for future backbone redundancy

High Speed Wireless Point to PointDeployment Detail and Interoperability
Utilizing systems that operate in the 5.8 GHz band, Orange County deployed Cambium Networks' wi4 Fixed Point-to-Point (PTP) 400 and 600 Series Wireless Ethernet Bridges to connect 24 locations including administration offices, public schools, the courthouse, the airport, and police and emergency services.

The County used the Cambium Networks PTP 600 Series radios to construct a subscriber-access backbone that extends over 30 miles. To overcome radio frequency interference challenges and path obstructions, Connectorized models with drum antennas were deployed. The radios were mounted on the County’s existing tower structures, making it easier to expand the network.

User networks are segmented via high-performance Ethernet switches with virtual LAN and access control points. The same network solution also supplies all government entities with Internet connectivity from a 45 Mbps DS-3 link. A security platform that includes firewall appliances, VLANs, global anti-virus, content filtering and bandwidth management applications is deployed at each network entry point to protect sensitive government data. Large users, such as the public schools, utilize Cambium Networks PTP 400 Series radios with integrated antennas to provide data rates of at least 18 Mbps, exceeding the County’s expectations. Smaller subscriber sites, such as the Orange County courthouse, use four-cell Cambium Canopy solutions.

After successful completion of the initial phase, the project was expanded to include many fire and rescue locations, allowing E-911 to print dispatch reports at the fire and rescue stations. E-911 sends the dispatch report to the printer located at the fire and rescue stations that have connectivity.

Wireless WANResults
To date, the wireless solution designed by Advanced Network Systems with the Cambium Networks PTP 400 and PTP 600 Series radios has proven to be an extremely reliable, high-performance, converged voice and data network. Paired with the County’s existing VoIP communication system, the solution effectively deploys telephony services at every government facility. Agencies immediately took advantage of computer management for e-mail, anti-virus control, file sharing and Internet services such as online Standards of Learning (SOL) testing capabilities for the County’s public schools. Plus, specialized services have been added, including video surveillance at the airport and E-911 information applications for police, fire and rescue departments. Substantial cost savings and ROI have resulted from the removal of analog voice lines that previously existed throughout the County’s system.

Later, the County added redundancy to its backbone for traffic re-routing. They have plans to connect three public libraries and two more emergency services locations. Other future plans may include the implementation of mobile data connectivity for emergency services enabled through the wireless network.
