Cal-(IT)2 is developing several generations of general broad application radio/networking test platforms for wireless research and development. CalRadio I is the first generation. It provides a simple, low-cost platform for 802. 11b development from the MAC layer and up. It accomplishes this by putting all the MAC functionality into `C` code that r

uns on a DSP. It uses the Intersil (Conexant) Prism chip set for the physical layer. Additionally, the C5471 Texas Instruments DSP contains an ARM processor that is used to host a small Open Linux operating kernel to provide easy access to programming, downloading and display/monitoring of data. CalRadio I functions both as a test instrument, an access point, and as a WiFi client. Support for the development was provided by Cal-(IT)2 under the direction of Ramesh Rao. The overall design of the system and development management was by Douglas Palmer with RF support by Don Kimball, both with Cal-(IT)2. The RF module design and initial MAC implementation software was provided by Symbol Technologies through the cooperation of Bob Beach and by Kamran Khojasteh. The CodeComposer software development studio for the TI TMS320VC5471 was donated by Texas Instruments thanks to Cathy Wicks. CalRadio I consists of three hardware components: MP Board, RF Module and enclosure, and the software/firmware to drive it. The MP board contains all the digital processing, memory, 802. 3 Ethernet interface, serial interface and
