CalRadio

WELCOME TO CALRADIO

CalRadio is a wireless transceiver research program that has the goal of developing general broad application radio/networking research and development test platforms. These platforms are for broad access by the wireless community and are made available to the public on an open basis for Research and Development. A single integrated test platform gives a new dimension to radio design in the future: the capability of publishing standards in software/firmware and hardware. This has the utility of greatly speeding the design, implementation and adoption of new standards.

News Flash: CalRadio Licensed to MaXentric Technologies LLC Jan3, 2008. The California Institute for Telecommunications and Information Technology has licensed the manufacture and sale of CalRadio units to MaXentric Technologies LLC of Fort Lee, NJ. Under the licensing agreement Calit2 will continue to develop software and hardware systems for CalRadio. According to the CalRadio program engineer, Douglas Palmer: "This is a tremendous boon for CalRadio users. MaXentric has tremendous engineering and support." From this point onward sales inquiries should go to MaXentric (see under sales.

News Flash: CalRadio to be Presented at MobiEval A paper discussing the design and parameterization of CalRadio will be presented by Aaron Jow at the upcoming MobiEval Workshop to be held in Puerto Rico in June 2007. A pre-release copy of this paper is available here. The abstract states:

"We present CalRadio, a flexible 802.11b wireless platform developed at UCSD for research and evaluation of 802.11 MAC protocols, as well as the methods we used to isolate desired field test data from undesirable factors such as inter- ference, and possible metrics we can use to evaluate network performance. CalRadio's purpose is to be a low-cost flexible wireless research platform that can be reconfigured easily and quickly depending on the needs of the researcher. Radio."

News Flash: CalRadio 1a Units Now On Sale! March 01, 2007. After a long development process and lots of testing CalRadio 1a units are now on sale! CalRadio has passed all of its tests with great success and the development team here at Calit2 is putting it into small-scale production (at last)! Several graduate students have been conducting their thesis work with the first few test units and have it very well characterized. They are slamming packets between radios at high speed with various modifications to the MAC code. Experiments are on-going to modify broadcast power on a packet by packet basis to minimize interference and to minimize power use. It will soon be utilized here on campus (UCSD) for evaluating mesh network algorithms and punch-through for noisy environments. We are very happy with the ease of programming and durability of the unit. Grad Student Aaron Jow can be seen daily on the soccer field conducting field tests with two CalRadios running on battery power.
We are selling CalRadio units for the cost of production (and a small administrative fee) at US$2499 apiece - payable to the Regents of the University of California. We suggest buying a pair! We are about to start another production run and are seeking orders or interest to gauge the size of the demand. If you are interested simply go here.
