Expert Witness

Telecommunications. Cellphones. Cell towers. GPS. Software. Patents.

David Allen Burgess

I have been working with cellular technology as a practicing engineer since 1998, in both government and commercial sectors. I have worked on eavesdropping systems, triangulation systems, and ordinary cellular networks and provided training to US government personnel on cell phone interception and tracking techniques. I currently develop cell tower equipment and support mobile operators in designing and deploying their networks.

  • software source code analysis in C/C++
  • patents in any of these areas

I also post video presentations on my YouTube channel.
