IP Vision

Morgan Hill, Calif., USA – AIRAYA, a world-class designer of proven predictable and affordable outdoor wireless video camera systems for high capacity public and government security and surveillance networks, and IP Vision Software partner to deploy a fully integrated secure licensed Public Works monitoring and surveillance system for the Orlando Utilities Commission (OUC—The Reliable One) in Orlando, Florida. The new wireless network extends the video surveillance and monitoring perimeter of OUC’s Curtis H. Stanton Energy Center, which encompasses about 3,000 acres and several remote locations that are diffi cult to patrol and monitor.

The wireless extension provided OUC with a scalable, fully integrated, secure solution that allows power company offi cials, Homeland Security and plant personnel to view live streaming video and archived video and to have VoIP capabilities to and from the most remote sections of the facility over a secure high speed network. With the AIRAYA and IP Vision Software, OUC is able to maintain a high capacity network with continuous streaming video, while offering the benefi ts of network integrity throughout the plant facility.

“We selected AIRAYA as the best wireless vendor for delivering the unique requirements presented by OUC,” said Mark Felberg, President and CEO of IP Vision Software. “AIRAYA’s mature solution includes a wide range of products, providing immediate out-of-the box connectivity and high performance, at an affordable cost. Demonstrating constant innovation in practice, AIRAYA offers a full range of supported frequency bands, channel widths and video tuning parameters, enabling us to successfully achieve our goal of supporting continuous streaming video over a large geographical area with a secure wireless network.”

The Challenge

Deliver a scalable, distributed security solution that will allow security personal access to live viewing, archived video and VoIP capabilities. The power plant provides electricity to more than 200,000 residents and businesses for the cities of Orlando and St. Cloud. Considered among Florida’s busiest and most reliable power plants, the Stanton Energy Center’s security plan must account for the large site and the need to monitor the remote locations and multiple entries into the plant. In some cases, the network cameras are located more than three miles away from the security station – a distance that would have made traditional cable-connected cameras cost prohibitive.

“The need for secure wireless private networks has increased signifi cantly around the country; together with leading local service providers and partners such as IP Vision Software, deployments have been very successful,” said Mike Nydam, CEO and President of AIRAYA. “As a result of Homeland Security initiatives across the country, we expect the secure outdoor wireless market to expand, for both license and license-exempt frequencies.” 

There were many deployment challenges:

• high RF interference

• the requirement to connect long distances of over 3 miles

• support for high density deployment of high resolution cameras

• provide aggregate bandwidth requirements in excess of 80 Mbps 


AIRAYA and IP Vision were responsible for the full design and deployment of the entire network. The system optimization and channelization for each bridge and camera were planned to meet the specifi c problems posed by the operating environment. The system required intelligent cameras with built in analytics at the edge of network that could be accessed via wireless technology.

“AIRAYA has the highest bandwidth and by far the lowest latency per hop – making AIRAYA the perfect solution for ‘Evidence Grade’ Wireless Video Surveillance for the Orlando Utilities Commission power plant,” Felberg said. 

The Solution

A fully integrated, rapid-deployment system ensures that OUC meets their long-term security objectives. The project consists of backhaul (Point-To-Point) links from three different gates to a central building 13 stories high. The network design then ties the video backhaul links together with a fourth link to the control room less than 1,000 feet away. None of the gates are visible from the control room directly. The AIRAYA solution met OUC’s requirements for capacity, speed, scalability and reliability, while optimizing available frequency.

The system uses the WirelessGRIDTM Full-Duplex Backhaul radios, and MoboticsTM high resolution IP cameras transmitting at MPEG-4 video at 30 frames per second. AIRAYA radios are capable of handling the high throughput requirements of video applications due to low latency Layer 2 operation, and tuning parameters to optimize the links. The surveillance cameras at the gates capture the license plates of vehicles when they are at the facility’s entrance. The video is managed with IP Visions’ video management software.

“With the wireless network and cameras now in place, we can now respond more quickly and monitor multiple remote areas,” said Charlie Wright, the Director of Security for OUC. “With AIRAYA and IP Vision, we placed cameras in areas we previously thought were too far for wireless equipment to reach or too expensive to trench with fi ber. The network really exceeded our expectations.”

AIRAYA’s WirelessGRIDTM backhaul radios offer the ultimate in installation flexibility with over 500 channels available through user-selectable features which include: 5, 10, 20 and 40 MHz wide channels, user selectable power settings and user selectable frequency range from 2.2-2.5 and 4.4-6.1 GHz. AIRAYA’s superior time sensitive packet performance is a function of the user selectable tunable parameters combined with low latency operation in a single link and the ability to address scalability with co-located high density links. AIRAYA’s 108/216 Mbps WirelessGRIDTM OFDM technology allowed AIRAYA and IP Vision to design a network that met the customer’s rigorous requirements.

 Public Safety Challenges in Hurricane Country

High-speed IP-based services between central public safety communication facilities and remote locations can be very challenging where weather is unpredictable and sometimes unforgiving. In such locations, public safety officials are challenged with using innovative technology to provide reliable communications between remote facilities.

St. Charles Parish, with a population of 42,437 people, in southern Louisiana is located in such an area. No matter what the conditions, the Parish Sheriff’s Office of over 358 fulltime men and women are dedicated to providing the highest quality law enforcement service in order to enhance community safety, to protect life and property, and to reduce crime.

Cary Armand, Information Technology Coordinator for St. Charles Parish Sheriffs Office (SCSO) is responsible for maintaining the SCSO network and application servers. Cary was faced with the challenge of keeping St. Charles Parish operable following the most devastating disaster ever to hit the county. The St. Charles Parish Sheriffs Office chose to implement a wireless solution by deploying AIRAYA’s WirelessGRID™ bridges for its IP communication system between central and remote office locations.

System Architecture and Deployment

The St. Charles Parish Sheriffs Office is utilizing AIRAYA WirelessGRID™ bridges with 5, 10, 20, and 40 MHz wide channels, providing four multipoint wireless links between central and remote locations, with aggregate system capacity averaging 75 Mbps. Two outdoor subscriber units were installed per base station and SCSO found that the radios were extremely easy to configure and install. The original deployment was cut over into service on March 07, 2006.


Since the initial deployment, SCSO has had no problems, resulting in zero downtime for the remote locations. “During initial testing we experienced no problems”, said Cary Armand, IT Coordinator for the St. Charles Parish Sheriffs Office. “We contacted AIRAYA’s technical support on two occasions during initial testing for general questions and guidance, and have been impressed with AIRAYA’s excellent service and technical expertise” he stated.

Mr. Armand goes on to say that “SCSO’s infrastructure of AIRAYA product have been in service and running successfully for over 9 months and we’re very satisfied with AIRAYA’s products, service and technical support”.

“AIRAYA’s products were very affordable and their exclusive bridge protocol and proprietary transmission mask provided the additional layers of security we required for our network. I would indeed recommend AIRAYA’s WirelessGRID™ bridges to others looking for a low cost, exceptional product that offers ease of installation, low maintenance, security, and excellent range & throughput”.

The AIRAYA advantage: Why AIRAYA?

In public safety implementations, WirelessGRID™ bridges are typically deployed in the licensed 4.9 GHz frequency band. WirelessGRID™ bridges are FCC Part 90 certified for high power radio operation; support multiple co-located base stations for higher system capacity; and support 5, 10, 15 and 20 MHz wide channels in 4.9 GHz for greater interference immunity. In addition, all public safety models of the WirelessGRID can operate in the 5.3 GHz and 5.8 GHz frequency bands, providing maximum utility and flexibility. Embedded AES encryption, AIRAYA’s exclusive bridge protocol and a proprietary transmission mask provide multiple layers of security for public safety and commercial networks.

The types of services actively being utilized across WirelessGRID™ public safety networks include video surveillance and location monitoring, TDM and VoIP voice, and many types of other IP data. AIRAYA WirelessGRID™ bridges provide a proven, timely and cost effective alternative to xDSL and satellite IP networks, as well as competing wireless solutions.

Safety Vision

Indianapolis today is a cosmopolitan blend of arts, education, culture, and sports; a city with plenty of vision for its future. Building on momentum gained in the last decade of the twentieth century, the city is in the midst of a technology and cultural quality-of-life resurgence. World-class sports, a diverse economy, the presence of healthy and successful businesses as well as innovative technology initiatives to promote municipal and community development, Indianapolis is poised and prepared to meet the challenges of the twenty-first century. As the eleventh largest city in the United States, the City of Indianapolis is world renowned for the Indianapolis Motor Speedway. The Indianapolis 500 is one of the premier international sporting events, drawing world-wide attention. Indianapolis in recent years has made dramatic strides in its national reputation through several city wide initiatives and has renovated its core historical structures, built new sports facilities, invested in the arts, entertainment, and technology.

At the heart of this progressive city is its state of the art public transportation system, IndyGo, which provides more than 8.5 million rides to people in the Indianapolis greater area who depend upon transit services to get them to and from their destinations quickly, efficiently and safely. To promote safety awareness, combat crime, shield itself from false insurance claims and help it keep tabs on its drivers and riders, Safety Vision chose AIRAYA as its equipment partner to deploy a wireless video and audio surveillance system on its entire transit fleet including Open Door vehicles. The system includes cameras that are a mix of color, black and white and night vision.

Thanks to AIRAYA and Safety Vision, IndyGo is now seeing a reduced accident claims and a heightened awareness of the system’s overall safety. Officials also will install surveillance on one of the transit agency’s smaller vans, which are used for curb-to-curb services.

“Our system is safe, and people rely on that safety every time they get on our buses,” said Gilbert Holmes, IndyGo President and CEO. “The security cameras give us another eye on the streets to not only observe the inside of vehicles, but to take a closer look at surrounding areas on the outside.”

“Our system is safe, and people rely on that safety every time they get on our buses,” said Gilbert Holmes, IndyGo President and CEO. “The security cameras give us another eye on the streets to not only observe the inside of vehicles, but to take a closer look at surrounding areas on the outside.”

“Since the installation of the system, our accident claims have dropped by 50 percent in part due to the security cameras,” added Holmes.

The Challenge

Deploy a Wireless Network Which Connects the Surveillance Cameras to a Central Center.

The upload of video and audio data from a bus or other in-motion vehicle to a base station has long been a challenge because of the greater bandwidth requirements of a wireless mobile audio/video system. A standard Wi-Fi or mesh solution will have bandwidth deficiency issues where the protocol cannot handle the high stream, time sensitive data transfer from the audio and camera equipment across the wireless network. This bandwidth deficiency causes the protocol to automatically reroute to another access point causing the protocol to terminate data transmission creating high latency in the system. This has long been a problem with standard Wi-Fi solutions. With AIRAYA’s user-selectable channel width and frequency capabilities real-time video streaming is truly feasible to be implemented over a wireless network. AIRAYA products all have a sub-one (1) millisecond latency. The result of operating in Layer 2 is high bandwidth and lowlatency because packet overhead is reduced.

Just as in important as simultaneous large file uploads, being able to select the appropriate channel width and frequency is also a crucial factor in real-time video streaming. Each camera manufacturer has their chosen data compression technique. Depending on the image resolution, compression format, frame rate, each camera will require appropriate throughput or bandwidth. AIRAYA radios are capable of handling the high throughput requirements of video applications due to Layer 2 operation, low latency and tuning parameters to optimize the links. The IndyGo project was in need of a solution that was robust as well as could handle the high speed and harsh bus environments. AIRAYA delivered the highest speed in the industry and with the lowest latency, as well as the ability to scale gracefully for the number of the busses that were connected.

The Solution

AIRAYA’s Rugged, Predictable, Robust and Secure Outdoor Wireless Solution. Using AIRAYA’s ruggedized and secure WirelessGRIDTM Mobile Subscribe Unit (MSU) and WirelessGRIDTM Base Stations (BSU), Safety Vision provided IndyGo with a reliable and affordable solution. The ideally suited AIRAYA equipment provided IndyGo with the optimal delivery of IP video, voice, and data services at a lower cost than or other wireless broadband solutions, with less maintenance and the ability to very quickly retrieve data from the system.

The WirelessGRIDTM Mobile Subscriber Units that were installed in each vehicle are specifically designed for use in harsh mobile environments with vibration and power spike protection. Another unique AIRAYA feature is a 12 or 24 Volt (8-30VDC Input) vehicle power cable, and a weather protected Ethernet cable connector. Out of the box the AIRAYA MSU is robust, powerful and rugged.

Delivering unparallel performance with AIRAYA’s 5, 10, 20 and 40 MHz wide user-selectable channel plan and AIRAYA’s 40 MHz wide channel, high capacity wireless data upload was possible. AIRAYA’s delivery of greater throughput is optimized by its use of available spectrum delivered through software selectable channels in the 2.2-2.5 and 4.90-5.85 GHz frequency range. Software selectable channel size and frequency range delivered by AIRAYA’s 108 Mbps WirelessGRIDTM OFDM technology allows for the AIRAYA’s partners to design networks that meet our customer’s rigorous requirements. The AIRAYA solution met IndyGo’s capacity, speed, scalability, and user needs, while optimizing available frequency.

Network Architecture

Benefits for IndyGo Riders, Drivers and City Officials

The AIRAYA WirelessGRIDTM Mobile Subscriber Units and Outdoor Wireless Base Stations were able to get the job done for Safety Vision and its customer IndyGo. For IndyGo officials, the wireless network has serve several purposes: Monitoring both drivers and riders for wrongdoing, scrutinizing drivers’ performances for training purposes and curtailing phony insurance claims. As an example, IndyGo will have the means to sift for video evidence of how a bus accident occurred.

“The footage and recordings will be admissible in court,” said Dale Meyers, IndyGo’s Information Technology Manager. Each bus is equipped with a computer hard drive that will record and store information. Those hard drives are protected by sturdy metal casings and are not accessible to drivers. The recorded information is downloaded for viewing through the AIRAYA wireless network when a bus returns to the IndyGo garage. Meyers characterized the quality of the video as being “slightly better” than surveillance camera footage one might see at a convenience store. IndyGo plans to pay for the $1.6 million initiative through a blend of federal grants and local money!

For drivers and riders it means safety.

Wireless Dynamics

Founded in the 1700s by European settlers, Nacogdoches is the oldest town in Texas. Nacogdoches is named for the Caddo family of Indians who once lived in the area. Nacogdoches is a historical city that increases in size during tourist season with visitors from around the world. It is considered one of the most historic towns in Texas with its rich Native American and Spanish heritage. Nacogdoches has a population of about 30,000 and is located approximately 130 miles SE of Dallas with a total area of 25.3 square miles (65.5 km²). Nacogdoches has a rich history that includes the state’s introduction to forward-thinking technological innovations such as the state’s first oil well drill and pipeline, and the countries first ceiling fan. Nacogdoches is now focused on meeting the goals of the “Digital Future,” tasked with bringing internet connectivity to its government agencies and services. Nacogdoches turned to AIRAYA and its partner Wireless Dynamics to accomplish a seemingly impossible goal; design and deploy a broadband wireless network for the historic city that was to “mimic” a fiber optic ring that would connect the city’s government offices and provide stable uptime for the city’s AMR project.

The progressive City of Nacogdoches is in the process of installing 16,000+ new wireless water meters that will be connected to the AIRAYA backbone. Nacogdoches will depend on the AIRAYA network to collect meter data each month to bill customers for water usage. “The City of Nacogdoches needed a Fast, Low latency connection in order to utilize VoIP, Internet and Corporate data to their city offices. We chose AIRAYA’s Full Duplex backhaul radios because of their high speed and very low latency. The GUI interface was very user friendly for the customer to maintain and the Telnet interface was a MUST for the install guys,” said Ronny Johnston, Lead Systems Engineer for Wireless Dynamics.

AIRAYA’s and Wireless Dynamics engineers faced several obstacles to a successful design and implementation; 1) the need to respect the historical integrity of the city, with many of the buildings and streets designated as historical landmarks, and 2) the need to connect and support the transmission of data between the city’s offices and other city services, while achieving maximum long-rang backhaul throughput over a long distances at far lower costs in time and money than Nacogdoches could have achieved using fiber optic cables or other wireless broadband solutions. The AIRAYA backbone was designed and built in a “ring” in order to provide fail over in case of power outage or other network outages. The fail over ring gives near 100% uptime as the water meter data is transferred at key intervals throughout the day from different locations within the city. Several vendors were considered for the project, but only AIRAYA’s backhaul radios proved capable of solving the interference issues surrounding the deployment. Another key driver was the efficiency of the innovative AIRAYA equipment, which is able to deliver predictable performance and service with less equipment than competing solutions while also supporting a larger number of users.

The Challenge

Creating Municipal Business Opportunities with Wireless Broadband.

The stated goal of the Nacogdoches City Government was to connect city offices without incurring the high cost of a fiber optics deployment while providing high speed network performance and predictability at an affordable price. The first and foremost challenges were the stated regulations prohibiting visible external antennas and wires in the Historical District as well as high interference at several locations. And finally, meeting high expectations and providing proof-of-concept for how a broadband wireless network can accelerate municipal business development and enhance quality of life and city services.

AIRAYA and Wireless Dynamics were responsible for the full design, channelization and deployment of the entire network, including system optimization and channelization for each bridge. Nacogdoches was particularly impressed by AIRAYA’s unique ability to provide complete plug-n-play, easy to use interface and configurable systems. The Nacogdoches project benefits from sophisticated 24 x 7 technical support, which is provided by the AIRAYA Support Center in Morgan Hill, California. Through the partnership with AIRAYA and Wireless Dynamics, Nacogdoches benefits from a powerful time-to-market advantage, and the ability to quickly evolve their network to meet new demands through the use of advanced technologies and services.

The Solution

Challenged with Connectivity and Obstacles AIRAYA Technology Meets the Challenge and Proves Instrumental in Nacogdoches Disaster Recovery. Unlike conventional wireless broadband bridges, AIRAYA’s WirelessGRIDTM backhaul radios are outdoor-ready WirelessGRIDTM full-duplex links that are specifically designed for rapid deployment in harsh environments. Rugged and fully weatherproof AIRAYA radios are designed for ease of configuration, diagnostics and management. Proven in thousands of private networks worldwide, WirelessGRIDTM radios are ideally suited for bandwidth-hungry applications that require robust, predictable, and secure connectivity. AIRAYA radios maximize range and capacity, as well as deliver ultra-low latency and outstanding performance in a dual-radio, single antenna configuration with asymmetrical dedicated transmit (TX) and receive (RX) radio paths. Purposebuilt to boost signal strength and enhance network performance, this powerful, innovative technology was instrumental in the success of the Nacogdoches project. Even in areas with high interference, the superior capabilities of the backhaul radios paved the way for a successful service rollout.

AIRAYA’s WirelessGRIDTM backhaul radios with user-selectable 5, 10, 20 and 40 MHz wide channel and power settings, allowed for the more than 500 channels in the 4.9-5.8 GHz frequency range solving the problem of mitigating the high RF interference in the area. The flexibility of the AIRAYA products removed the contention of frequency interference in the area and allowed the city to open more channels which allowed the network to operate more efficiently with greater throughput. The channel configurations of the radios were accomplished without having to uninstall the equipment that was deployed. The channels upgrade was entirely done in the software and as a result the Nacogdoches network achieves a high throughput of 30Mbps of Full Duplex performance.

AIRAYA’s WirelessGRIDTM backhaul radios proved their reputation for reliability and rugged design after the eye of hurricane Ike passed just west of Nacogdoches, all electricity in the city was knocked out by the powerful storm. As soon as power in the city was restored, the AIRAYA backhaul radio came up without any failure or loss of equipment and provided data and communications to the city immediately without any interruptions.

To ensure the success of wireless projects of any size, planning is critical. The City of Nacogdoches had a clear view of its needs from the start. Cost and performance were important, considering the wide area of deployment. In addition, the network needed to provide:

• Predictable connectivity in a diverse geographical area

• Hassel free installation and configuration

• Intuitive system management interface

• Flexibility and value

AIRAYA’s WirelessGRIDTM technologies were particularly well suited for the types of challenges the City of Nacogdoches was facing by providing, predictable packet delivery, high performance, and software definable flexibility at an economical price. Nacogdoches’ dispersed geographic and high interference areas required a “cost efficient” and “no disruptions to the city” solution which are not possible with current wired networks. AIRAYA was pleased to partner with Wireless Dynamics on this project and look forward to working together in the future.

Network Architecture

Wireless Dynamics has selected AIRAYA’s WirelessGRID™ Full-Duplex Backhaul Links as the workhorse of the Nacogdoches network. To enhance network performance, the WirelessGRID™ 29 dBi Dual Polarity Dish Antenna was also deployed to reinforce and prvide the coverage and throughput of the requirement the infrastructure and provide backhaul connectivity to the network. Currently the network provides coverage to the perimeter of the City and to all of its government offices.

Winnebago County


Part of the Rockford metropolitan area, Winnebago County is the third most populous region in Illinois. In addition to managing the local government and public safety facilities of the county, Winnebago County has an active economic development mandate to promote balanced growth and develop new industry beyond their traditional reliance on the manufacturing sector.


Winnebago County operates a communications backbone network interconnecting several critical government and public safety facilities, including a 911 contact center, justice center, county courthouse, and county health department. An aging network infrastructure, comprised of unlicensed microwave and costly leased lines, was not providing the reliability or scalability needed to support the county’s increasingly bandwidth intensive video and internet connectivity applications. With plans to upgrade additional facilities with the latest public safety infrastructure and applications, Winnebago County was in need of a significant overhaul to their transport network.

The new solution had to meet several important requirements established by the County. The first priority was to deploy a future-proof solution with scalability beyond 1 Gbps to ensure plenty of extra capacity to support future growth. The critical nature of their public safety network required a highly reliable carrier-grade solution. The County was also under pressure to deploy quickly with minimal disruption to their facilities and staff.

Given the capacity requirements, it was determined that either a fiber, microwave or eband solution would be needed. With links in excess of a mile, the eband solution was eliminated, and the cost and difficulty of adding to existing fiber facilities was considered a non-starter. Additionally, Winnebago County officials were impressed with the path diversity and redundancy that microwave could deliver.


After a comprehensive evaluation process conducted by Winnebago County’s network communications team, DragonWave’s Horizon Quantum packet microwave solution was selected for its unique features and unmatched scalability.

Success Story

Looking for a turnkey provider, Winnebago County worked with Urban Communications, a platinum DragonWave partner, who completed the installation of the solution and is now managing the ongoing operation of the Winnebago County network.

Winnebago County now has more than 50-times the scalability of their previous transport solution. Their advanced packet microwave ring interconnects vital government and public safety facilities including a 911 contact center, justice center, courthouse, economic development center and county health department  with expansion to additional locations being explored.
