## Ohio State Highway PatrolSecure Mobile Networking Demonstration

- A Technical Overview of the Network and Data Flow
- (Dave Stewart, Terry Bell and Will Ivancic)

## 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

## Scenario

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

## 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

## 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.

## 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.

## 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).
