This is your Tech Tidbits Daily for Tuesday, April 5th, 2005. Today’s podcast contains two items of potential interest from Military & Aerospace Electronics published for March 2005 and one listener feedback:

• The first is an article that highlights a recent demonstration of mobile communications at Fort Gordon, Georgia for a Department of Defense initiative called Command and Control On-The-Move. Using some new equipment and techniques from ViaSat the demo was able to show equivalent DSL connections (3-mbps downstream; 256-kbps upstream) to a moving Humvee using secure encryption devices.  The key networking protocols utilized to accomplish this include: Paired Carrier Multiple Access (PCMA) and Code Reuse Multiple Access (CRMA).
• The second is a very detailed article on a new initiative by German-based Fraunhofer Institute for Reliability and Microintegration to take a cubic "eGrain sensor" from 2.6-cm per side down to 1-cm per side by late 2005 through a series of iterative steps.  The eventual goal of this project is to get a sensor which needs to be able to offer not only sensing (like heat or frequency) but also communications and power down to a 5-mm cube form factor that is also low-cost to produce. The article did not have an estimated time-line for the 5-mm device, but the article did note that there are significant technology challenges laying ahead in processing and controlling large numbers of deployed sensor devices.
