K7DAN writes "The AP reports that Mexico's drug cartels have built their own sophisticated two-way radio communications system using computer-controlled linked and local repeaters on mountain tops, walkie-talkies, mobile transceivers and and base stations. The solar powered system covers vast areas of Mexico that are unserved by cellular phone network and has the advantage of being more difficult to trace." This article adds much more substance about the technology than was included in the report several weeks ago of the seizure of thousands of this network's components; from the description in this article, the earlier headline overstated the case by saying that the network had therefore been "shut down."
