calradio
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 runs on a DSP. It uses the Intersil (Conexant) Prism chipset for the physical layer. Additionally, the Texas Instruments C5471 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 were provided by Symbol Technologies through the cooperation of Bob Beach and Kamran Khojasteh. The Code Composer 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, and serial interface.
CalRadio I serves as a foundational platform for wireless networking research and development, specifically targeting the 802.11b protocol. It integrates a Digital Signal Processor (DSP) that executes the Media Access Control (MAC) layer functionalities entirely in C code, facilitating a streamlined development process. The use of the Intersil Prism chipset establishes the physical layer, ensuring compatibility with existing wireless standards.
The Texas Instruments C5471 DSP is pivotal to this architecture, as it incorporates an ARM processor capable of running a lightweight Open Linux kernel. This kernel allows developers to easily program, download, and monitor data, enhancing the usability of the platform. The versatile nature of CalRadio I allows it to function not only as a testing instrument but also as an access point and a WiFi client, making it suitable for various research applications.
The development of CalRadio I was a collaborative effort, with significant contributions from Cal-(IT)2 under the leadership of Ramesh Rao. Douglas Palmer oversaw the system design and development management, while Don Kimball provided RF support. The RF module design and initial MAC implementation were facilitated by Symbol Technologies, with contributions from Bob Beach and Kamran Khojasteh. Furthermore, Texas Instruments supported the project by donating the Code Composer software development studio tailored for the TI TMS320VC5471, thanks to Cathy Wicks.
The hardware architecture of CalRadio I is comprised of three primary components: the MP Board, the RF Module, and the enclosure. The MP Board is central to the system, housing all digital processing elements, memory, the 802.3 Ethernet interface, and a serial interface. This modular design allows for flexibility and scalability in research and development endeavors, making CalRadio I an essential tool for advancing wireless networking technology.Cal-(IT)2 is developing several generations of general broad application radio/networking test platforms for wireless research and development.
