New Wireless Network Access Control Solution

Talbot County Schools Administration building

Abstract

This wireless network access control solution helped this public school district in Maryland prepare for the future with a new controller, access points, switches, and upgrades to the existing infrastructure.

The challenge

Talbot County Public Schools (TCPS), located in Maryland’s eastern shore, devotes a significant portion of its academic learning improvement plan to complying with the Maryland High School Assessments (HSAs) requirements. The HSAs are three tests (algebra/data analysis, biology, and English) that comprise one part of Maryland’s graduation requirements. An emphasis must be placed on learning and preparing to pass these exams, for which TCPS has developed a four-year improvement plan to ensure success.

In an effort to ensure that every student demonstrates improved academic achievement, TCPS instituted a one-to-one computing initiative which provides each its Easton High School students with an Apple laptop computer to encourage technology-based learning. TCPS was then faced with a range of challenges to ensure their users have reliable and secure wireless access.

Talbot County Public Schools enlisted Data Networks to implement a complete wireless network solution, from design to installation and configuration. An emphasis was placed on keeping existing core network equipment and cabling infrastructure, while positioning the core network for growth. In addition, TCPS needed a solution that could scale as more schools upgrade, with central management from EHS, and allow appropriate and secure access for students, teachers, staff, and guests.

The solution

Data Networks performed a site survey and developed a new Wireless SAN solution and related infrastructure upgrade at Easton High School, providing professional services related to the staging, installation, configuration, testing, and project management necessary for implementing this solution. Leaning on our premier partners Aruba and Juniper, Data Networks designed a solution that supplies the performance, security, management, and scalability TCPS needed at the lowest TCO.

The Aruba portion of the solution included:

  • Installation and configuration of a new Aruba Networks 6000 series
  • Wireless Controller
  • Upgrade to latest supported version of ArubaOS
  • Replacement of existing Access Points with 80 new Aruba AP-125 802.11ABGN dual-radio access points

The Juniper portion of the solution included:

  • Installation of four (4) new Juniper EX4200 Ethernet switches in existing equipment rack in the MDF; two (2) new Juniper EX4200 Ethernet switches in the server room and one (1) Juniper EX3200 Ethernet switch in each of the three existing IDFs
  • Upgrade to the latest supported version of JUNOS
  • Configuration of 802.11 trunk port on one 10GE uplink (SFP + LRM) to the existing Cisco switch
  • Configuration of switch stacks in a Virtual Chassis for centralized management
  • An end-to-end test of the wired and wireless networks

Mission accomplished

Using a dynamic configuration deployment method, the existing network was leveraged to provide the configuration details needed for access points to locate and communicate with the mobility controller to receive a software image, initial configuration parameters, and post-deployment configuration. The controller contains an integrated network management system that configures, controls, and operates all mobility controllers and access points in the entire network, and allows for up-to 512 access points as the network expands.

“To position TCPS with a scalable solution, Data Networks was able to provide secure wireless network access and integrate upgrades to the existing infrastructure,” says Dwayne MacKenzie, Data Networks’ Networking & Security Solutions Architect. “The EHS students, teachers, staff, and guest users now enjoy fast, secure wireless with minimal impact on the TCPS technology staff.”
