CalRadio®
CalRadio® is the first generation of general broad application radio/networking test platforms for wireless research and development. It provides a simple, low-cost platform for 802.11b development from the MAC layer and up. CalRadio® 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® puts all the MAC functionality into 'C' code that runs 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 displaying/monitoring data. CalRadio® functions as a test instrument, an access point, and a WiFi client.
Additional details regarding CalRadio®, including the BOM, schematics, and other information required to build, test, and evaluate the technology, can be found here.
