  1. Ohio State Highway PatrolSecure Mobile Networking Demonstration A Technical Overview of the Network and Data Flow (Dave Stewart, Terry Bell and Will Ivancic)

  2. Mobile-Router Advantages • Share wireless and network resources with other organizations • $$$ savings • Set and forget • No onsite expertise required • However, you still have to engineer the network • Continuous Connectivity • (May or may not be important to your organization) • Robust • Dynamic (Secondary) Home Agent

  3. Scenario • Mobile command center deployed at hostage situation. • Satellite connectivity needed for reachback to Internet from mobile command center.

  4. Network Concept • OSHP Bus is remote control center during emergency situations • Reachback to the Internet can be provided in a number of ways including satellite, rapidly installed land lines (T-1) or G3/G4 Cellular • Demonstration Room in Patrol Academy represents OSHP Headquarters • Patrol Cars are the mobile networks

  5. Requirements • Rapidly Deployable – no onsite expertise required • Contact between patrol cars and remote command center are of greatest importance. • Desire to have voice, data, and – given sufficient bandwidth – video between the patrol cars and the bus and/or headquarters. • Desire to monitor and control sensors and cameras remotely from the remote command center or headquarters.

  6. Full Scale Deployment • Data would NOT flow from the mobile command center to Headquarters via a private 802.11 link. • Instead, encrypted data would come into Headquarters via the Internet.

  8. Demonstration Caveats • To ease demonstration setup and configurations, all data from the mobile networks passes through the wireless encryptor. • No encrypted data flows from the Internet directly to Headquarters • To ease configurations, mobile units communicate to each other via Headquarters (probably via the remote control center in a real deployment).
