Wireless Communication System
Two RF Transceivers that transmits and receives wireless RS232C Data
Process: One Transceiver accepts RS232c data and converts the data to Radio Frequency. The other Transceiver receives the RF data and converts it back to RS232c
Wireless Transceiver: Specifications
OTEK TR200 Series Transceivers
• 100/300 feet range
• 916.5 MHZ Operating Frequency
• Transmission Rate of 19,200 BPS
Wireless Communication: Protocol
Sender’s Protocol
• Proprietary software made by OTEK, manual input that runs on DOS
Receiver’s Protocol
• Program developed in C that parses control and input data, reads and writes to the serial port
Interactive Display: Visual Dashboard
Purpose: To display real-time information from Whitney to a computer on a separate vehicle

Telematics: Summary
• Wireless Communication proved to be successful, however the proprietary software became a limitation
• Visual Dashboard Interface can display the information from Whitney, what is the next step?
• Automotive Telematics has become the new trend in traveling: enabling safety, security, entertainment, and navigation
