Project Description  Design a mid-range RF module that will serve as the communication link between a base station and a land vehicle for automated control  The module is part of the Wireless Open- Source/Open-Architecture Command and Control System (WOCCS)  Module is to be used to educate incoming FYE students – controlling wireless vehicles  Module will be incorporated into future senior design projects

Customer Needs Importance: 9=High, 3 = Moderate, 1= Low

Specifications Importance: 9=High, 3 = Moderate, 1= Low

System Architecture

Selected Concept  From multiple concepts, the following were selected Transmission Type – External RF Antenna User Data Protocol – USB RF Protocol – SimpliciTI Visual Feedback – Status LEDs Microcontroller/Transceiver – CC1111 System on Chip

Final Product SMA Connector Programming Connector Grounding Clip 915MHz Antenna CC1111 System on Chip External Status LEDs USB Connector Power Connector Internal Status LEDs Power Switch

Project Status  Design meets all customer needs  Design passed all engineering specifications  Project is under budget  Software implementation could be optimized for data rate performance

Testing Results  Fields in green are the values achieved on final prototype Importance: 9=High, 3 = Moderate, 1= Low

Major Issues  Hardware Board thickness and housing thickness did not match – housing rails were widened Implemented incorrect external crystal pin layout – needed to be rotated 90°  Software Data write speed from PC to the module is limited

Evaluation  Project has been successful in designing and producing a small-scale wireless system  The modules can be used in future projects Portable Medium-range communication link Easy to interface Adaptable to many diverse remote applications.  Future Work Data can be sent too quickly to the module over USB - currently resolved by rate-limiting the software that communicates with the module A more elegant software solution could be developed on the microcontroller in the future
