Keller Independent School District, one of the fastest-growing school districts in Texas, has taken delivery of a system that streams high-quality video and other multimedia resources to the classroom without interruption, providing on-demand access to content and instructional tools.

The implementation, using gear from Motorola and Safari Montage, lays the foundation to support the school district's broader K-12 e-learning initiatives, which include putting wireless devices in the hands of every student to enable district-wide visual learning.

"Our existing wired infrastructure limited where and how users could access the content," said Joe Griffin, CTO of the district, comprised of 36 schools serving more than 30,000 students. "We needed a cost-effective solution that could provide high-speed, district-wide coverage and ensure seamless delivery of multimedia content to students and teachers, while supporting our efforts to expand these capabilities to all classrooms."

With a plan to move to a digital curriculum, it was crucial for the district to have a reliable and easy-to-use wireless infrastructure in place that would support one-to-one instructional objectives and enable visual teaching district-wide, said district Superintendent James Veitenheimer. "We also needed a network that could work at a very high level and make it easy for students and teachers to use," he said.

To support the high-bandwidth requirements needed to distribute large, high-quality digital video files from the Safari Montage system, Keller turned to System ID, a leading system integrator and Motorola channel partner, who recommended Motorola's 802.11n wireless LAN (WLAN) infrastructure and Motorola AirDefense wireless security and network assurance solutions.

"Keller ISD needed a robust wireless network that could handle the delivery of multiple multicast and unicast video streams simultaneously, to many clients in classrooms across the school district," said Marshall Huffman, director of advanced solutions at System ID. "After testing several vendors, the Motorola WLAN solution was the best performing network for streaming video and other multimedia content to high densities of users, which is critical in the classroom environment."

Motorola's 802.11n WLAN solution enables Keller ISD to deliver reliable video and other multimedia resources over a Wi-Fi network--replacing what was previously handled over a wired network. Leveraging Motorola's RFS7000 wireless switches, coupled with dual- and tri-radio AP-7131 access points (AP), the network is optimized to handle high user density and provides maximum coverage to support multiple voice and video streams, as well as complex data applications.

The unique tri-radio 802.11n AP allows one radio to be dedicated to security and troubleshooting, while the remaining two radios enable high-speed access and delivery of optimized multimedia content. This eliminates the cost and complexity of deploying separate sensor radios, while ensuring secure, reliable delivery of content.

In addition, Keller ISD installed the Motorola AirDefense Wireless Intrusion Prevention System (Wireless IPS), for 24x7 wireless security and proactive monitoring, and the Motorola AirDefense Advanced Troubleshooting module, which is a component of the Motorola AirDefense Network Assurance Suite.

"Video is a powerful tool for today's educators that can significantly enhance the student learning experience. But to truly benefit, schools need to have the right infrastructure in place to support the high bandwidth and quality of service required to deliver rich multimedia content, not just to the teacher's classroom computer, but to all wireless devices--from Netbooks to mobile phones," said Tim Beekman, president and co-founder of Safari Montage. "Motorola's WLAN solution provides Keller ISD with the flexibility to deliver educational digital content anywhere, anytime throughout the district, without having to give up quality or quantity. This is the first wireless network that has been able to deliver our content successfully."
